Brightening body milks combining tranexamic acid (TXA) and kojic acid are among the fastest-growing SKUs in the skin-tone-evening segment. Both actives target melanin synthesis through complementary pathways — TXA disrupts plasminogen-keratinocyte interaction while kojic acid chelates the copper cofactor in tyrosinase — making the blend highly effective and increasingly demanded by indie founders worldwide. Finding a manufacturer that can handle both actives at effective concentrations, keep your MOQ low, and still hit label-compliant finished goods is the real challenge.
What Makes a Good Tranexamic Acid + Kojic Acid Body Milk Formula?
A well-formulated brightening body milk balances actives with a stable emulsion base. Key formulation considerations include:
| Ingredient | Effective Range | Common Usage Level | Primary Function |
|---|---|---|---|
| Tranexamic Acid | 1%–5% | 2%–3% | Reduces UV-induced melanin transfer |
| Kojic Acid | 0.5%–2% | 1% | Tyrosinase inhibition, brightening |
| Niacinamide (supporting) | 2%–5% | 3% | Melanin transfer inhibition, barrier support |
| Alpha Arbutin (optional) | 0.5%–2% | 1% | Additional tyrosinase inhibition |
Kojic acid is notoriously unstable — it oxidizes and discolors in the presence of light, iron, and high pH. Your cosmetic chemist must formulate at pH 4.5–6.0, use chelating agents like EDTA or phytic acid, and select appropriate antioxidant packages. Ensure your manufacturer can provide accelerated stability data (typically 12 weeks at 40°C/75% RH) before you commit to a large run.
MOQ and Cost Ranges for Private Label Body Milk
MOQ and unit cost vary significantly based on whether you choose a stock (white-label) base or a fully custom formula. The table below reflects typical ranges from contract manufacturers in the US, South Korea, and Southeast Asia.
| Route | MOQ | Unit COGS (unfilled) | Lead Time | Customization |
|---|---|---|---|---|
| Stock formula, private label | 100–500 units | $3–$7 | 4–8 weeks | Label, fragrance tweak only |
| Semi-custom (modify stock base) | 300–1,000 units | $5–$12 | 8–14 weeks | Active levels, scent, texture |
| Fully custom formula | 1,000–5,000 units | $8–$20+ | 12–24 weeks | Full IP ownership, unique INCI |
Development fees (NRD — new recipe development) typically range from $500 to $3,500 for custom formulas and are often waived or credited back at certain order volumes. Always request a sample run of 20–50 units before approving a production batch.
Regulatory Considerations for TXA and Kojic Acid Products
Tranexamic acid is cosmetically approved in the US, EU, and most of Asia-Pacific when used at typical cosmetic concentrations. It does not currently appear on any restricted lists, but it must not be presented with drug claims (e.g., "treats melasma"). Kojic acid has stricter regional treatment: the EU's SCCS has reviewed kojic acid and imposed concentration caps — currently 1% in face products and under ongoing review for body applications. The US has no hard cap, but responsible formulation keeps it at or below 2%. Japanese manufacturers often formulate to Japan's quasi-drug (医薬部外品) standards which allow higher kojic acid levels under licensed categories. Choose your manufacturer based on the markets you intend to sell into, and ensure your cosmetic chemist produces a complete INCI list and Safety Assessment (PIF in the EU; CPSR in the UK post-Brexit).
How to Find and Vet a Low-MOQ Manufacturer
Sourcing a manufacturer for brightening body milks requires more than a Google search. Vetting steps include requesting GMP certification (ISO 22716 is the global benchmark), reviewing the manufacturer's existing TXA or kojic acid formulation experience, requesting a Certificate of Analysis (CoA) for raw materials, and confirming they can meet your target market's labeling requirements. Founders on AJ Cosmo Labs post a product brief directly inside the iOS app and receive responses from pre-screened cosmetic manufacturers and formulators — cutting the typical cold-outreach cycle from weeks to days.

Frequently asked questions
What is the minimum order quantity for private label tranexamic acid kojic acid body milk?
The minimum order quantity for a private label tranexamic acid and kojic acid body milk depends primarily on whether you choose a stock (white-label) formula or a custom-developed formula. Stock formulas — where a manufacturer already has a validated brightening body milk base and you simply add your brand label and optionally adjust fragrance — typically start at 100 to 500 units per SKU. These are the most accessible entry points for indie founders and startup brands testing a new market. Semi-custom routes, where you modify a stock base to adjust active concentrations, switch the emollient package, or alter viscosity, generally start between 300 and 1,000 units. Manufacturers charge a modest development or reformulation fee (usually $300–$1,500) to cover cosmetic chemist time and stability retesting of the modified formula. Fully custom formulas — where you own the IP and the INCI list is unique to your brand — almost always carry MOQs of 1,000 to 5,000 units, because the manufacturer needs to amortize new recipe development costs (typically $500–$3,500) and stability testing (accelerated and real-time) across a meaningful volume. Geography also moves the MOQ needle. South Korean K-beauty OEMs, particularly those in the Incheon and Gyeonggi corridors, are well-accustomed to small-brand briefs and often offer lower MOQs than US-based facilities for the same formula type. Southeast Asian manufacturers in Malaysia, the Philippines, and Vietnam are a growing option for budget-conscious founders targeting halal-certified formulations. Factors that can push MOQ higher include packaging complexity (airless pumps and specialty bottles often have their own 1,000-unit packaging MOQs), regulatory market (EU-compliant batches require a PIF and may require larger quantities to justify the regulatory overhead), and active concentration (very high TXA or kojic acid levels may require custom raw material procurement with their own supplier MOQs). The most common first-timer mistake is quoting a 200-unit MOQ to a manufacturer and then discovering that the bottle they've chosen has a 1,000-unit packaging MOQ — effectively raising the real production minimum to 1,000 units. Always confirm packaging MOQs separately from formula MOQs. On AJ Cosmo Labs, founders can filter manufacturers directly by MOQ threshold inside the iOS app, so you're only seeing partners who can realistically work at your current scale.
How much does it cost to private label a kojic acid tranexamic acid body milk?
The total cost of bringing a private label brightening body milk to market has several distinct components, and conflating them is the most common budgeting mistake founders make. First, there is the cost of goods sold (COGS) per finished unit. For a stock formula with private label branding, COGS typically runs $3–$7 per 200–250ml bottle, depending on active concentrations and packaging tier. Semi-custom formulas land at $5–$12 per unit, and fully custom formulations at $8–$20 or more per unit, reflecting the additional raw material sourcing and quality control overhead. Second, there are development fees. Custom formula development typically costs $500–$3,500 as a one-time project fee paid to the cosmetic chemist or manufacturing R&D team. This covers prototype development, 2–3 rounds of revision, and initial bench stability screening. Many manufacturers waive or credit this fee back at a certain volume threshold — commonly 1,000 or 2,000 units placed within 12 months. Third, stability and safety testing adds cost. Accelerated stability testing (12 weeks at 40°C/75% relative humidity) typically costs $800–$2,500 depending on the lab and number of conditions tested. For EU or UK markets, a full Cosmetic Product Safety Report (CPSR) from a qualified toxicologist costs $400–$1,200 per SKU. Fourth, packaging is often the most underestimated cost. A well-designed airless pump bottle with custom color and embossing can cost $0.80–$2.50 per unit at a 1,000-unit packaging MOQ. Standard white HDPE bottles with a lotion pump run $0.25–$0.60 per unit at similar volumes. Fifth, labeling and printing: custom labels for a 200ml body milk bottle typically cost $0.10–$0.40 per unit when ordered in quantities of 500–2,000. For a realistic all-in budget, a founder launching at 500 units of a semi-custom formula should expect to spend $6,000–$12,000 for the first production run, inclusive of development, stability, packaging, filling, and labeling. A 1,000-unit run of a fully custom formula targeting the EU market can range from $15,000 to $30,000 when compliance costs are included. AJ Cosmo Labs helps founders compare quoted costs from multiple manufacturers in one place through the iOS app, making it easier to benchmark COGS before committing to a partner.
Is kojic acid safe and legal to use in body milk in the US and EU?
Kojic acid is legal for use in cosmetic body milk in both the US and EU, but the regulatory environments differ meaningfully and founders need to understand those differences before selecting a target market. In the United States, the FDA does not impose a specific concentration cap on kojic acid in rinse-off or leave-on cosmetics, because it is regulated as a cosmetic ingredient rather than an over-the-counter drug (provided no drug claims are made). Most US-market formulators keep kojic acid at 0.5%–2% in body applications. The key compliance requirement is that claims must not cross into drug territory — statements like 'treats hyperpigmentation' or 'corrects melasma' can trigger OTC drug classification and FDA enforcement action. Acceptable claim language includes 'evens skin tone', 'visibly brightens', and 'reduces the appearance of dark spots'. In the European Union, the SCCS (Scientific Committee on Consumer Safety) has issued opinions on kojic acid multiple times. The current position, as of the most recently adopted restriction under Regulation (EC) 1223/2009, restricts kojic acid to a maximum of 1% in face products. Body product applications remain under active scientific review. EU-compliant brands operating conservatively often cap kojic acid at 1% in body milk as a precautionary measure and ensure this is clearly documented in the Product Information File (PIF). Brands entering the EU market must appoint a Responsible Person established in the EU and maintain a full CPSR. In the United Kingdom post-Brexit, kojic acid follows its own GB cosmetics regulations (essentially mirroring EU standards through retained law), and brands must maintain a UK-specific RP and PIF. In Japan, kojic acid has a long-standing approval as a quasi-drug (医薬部外品) active for skin brightening at concentrations up to 1%, which gives it a legitimacy and market familiarity that is sometimes stronger than in Western markets. K-beauty and J-beauty manufacturers are experienced in formulating compliant brightening products for multiple regulatory zones simultaneously. Transexamic acid (TXA) is far less regulated at cosmetic concentrations. It appears on no major restricted lists in the US, EU, or UK as of the time of writing, and is typically used at 2%–3% in cosmetic body milks without regulatory concern, provided drug claims are avoided. The common mistake is launching a kojic acid product into the EU at 2% without a SCCS-compliant safety assessment. EU customs and market surveillance authorities do pull products, and a non-compliant product can be withdrawn from market at significant cost. Always commission a CPSR from a qualified EU toxicologist before EU launch.
How long does it take to manufacture a private label brightening body milk from scratch?
The timeline from initial concept to finished goods for a private label tranexamic acid and kojic acid body milk varies significantly by route, but most founders should plan for 8–20 weeks when they first approach a manufacturer. For a stock formula with private label branding only, the timeline is shortest: 4–8 weeks, accounting for label artwork approval, label printing lead time (typically 2–3 weeks), filling scheduling, and quality control release. If you already have approved artwork files, some manufacturers can turn around an in-stock formula in as few as 3 weeks. For a semi-custom formula, the process adds a formulation revision phase. A cosmetic chemist will modify the base to your requested active concentrations, produce bench samples (usually 50–200g), and send them to you for sensory evaluation. This back-and-forth typically takes 3–6 weeks. Following formula approval, accelerated stability screening (a subset, not the full 12-week study) may be required before production scale-up, adding another 4–6 weeks. Total: 8–14 weeks. For a fully custom formula, you should budget 14–24 weeks for the complete development cycle: initial brief and chemist briefing (1–2 weeks), prototype development (3–5 weeks), revision rounds (2–4 weeks), full accelerated stability and compatibility testing (8–12 weeks, partly parallel with other steps), regulatory documentation (2–4 weeks for EU/UK), and production scheduling and filling (2–4 weeks). Many manufacturers run stability testing in parallel with revision and documentation, which compresses the timeline, but you should not approve a production batch before seeing at minimum 8 weeks of accelerated stability data. The stage that most founders underestimate is regulatory documentation. If you are targeting the EU market, commissioning and receiving a completed CPSR from a toxicologist typically takes 4–8 weeks after the formula is finalized. That cannot be parallelized if the formulation is still changing. Supply chain delays for specialty actives — particularly pharmaceutical-grade tranexamic acid — can add 2–6 weeks if your manufacturer does not hold safety stock. Always ask about raw material lead times before signing a development agreement. AJ Cosmo Labs connects founders with manufacturers who list their current production queue and typical lead times inside the app, so you can filter for partners who match your launch calendar from the start.
What should I look for when choosing a contract manufacturer for TXA kojic acid body milk?
Choosing the right contract manufacturer for a tranexamic acid and kojic acid body milk is one of the highest-leverage decisions an indie brand founder makes, and the vetting criteria go well beyond price and MOQ. GMP certification is non-negotiable. ISO 22716 (Good Manufacturing Practices for Cosmetics) is the global standard and is required for EU compliance and strongly expected for US retail. Some manufacturers hold additional certifications such as NSF/ANSI 455, Halal GMP, or Korean CGMP — these are bonuses depending on your target market. Ask for the certificate and verify its expiry date; some are issued and never renewed. Formulation experience with specific actives matters more than general cosmetic experience. Kojic acid is notoriously unstable — it discolors at high pH, in the presence of iron contamination, and under UV exposure. Ask the manufacturer whether they have existing stability data for kojic acid formulations, and at what concentrations. Manufacturers without prior TXA experience may not understand its compatibility with cationic emulsifiers or certain preservative systems. Request references or portfolio examples. Analytical capability is critical. Your manufacturer should be able to run HPLC or UV-Vis assays in-house or through a contracted analytical lab to verify that the finished product contains the labeled concentration of TXA and kojic acid at batch release. This is especially important because kojic acid degrades — without active concentration testing, you cannot know if what's in the bottle matches your label. Stability testing infrastructure: at minimum, the manufacturer should have temperature- and humidity-controlled stability chambers capable of the ICH Q1A-equivalent conditions used for cosmetic stability (40°C/75% RH for accelerated; 25°C/60% RH for real-time). Some small manufacturers outsource this, which is acceptable if turnaround times are reasonable. Regulatory support capability varies widely. If you need EU, UK, or GCC market compliance, confirm the manufacturer can produce a full technical dossier and works with qualified safety assessors. Many Asian OEMs have EU-experienced regulatory teams on staff or on retainer — ask specifically. Minimum batch size and equipment: body milk is a water-in-oil or oil-in-water emulsion produced in tanks typically ranging from 50L (pilot scale) to 1,000L+. Verify the manufacturer has a pilot-scale tank appropriate for your MOQ so you're not being processed as an afterthought on a 2,000L production run. The most common mistake founders make is choosing a manufacturer based on a low quote without auditing these criteria — only to discover mid-project that the manufacturer cannot produce stability data, cannot hit the active concentration reliably, or cannot support the regulatory documentation needed for their target market. AJ Cosmo Labs admin-reviews all manufacturing partners on the iOS app, with certifications and capabilities on file, so the default search pool is already filtered for qualified suppliers.
Can I get a custom scent in my private label brightening body milk at low MOQ?
Yes, custom fragrance can be incorporated into a private label brightening body milk even at low MOQs, but there are important constraints that founders need to understand before requesting one. Most contract manufacturers offer a library of in-house fragrance compounds that you can select and apply to your formula at no additional development cost, and at the same MOQ as the unscented base. These are often described as 'standard' or 'stock' fragrances. Common options for brightening body milks include light florals, fresh citrus blends, sakura or cherry blossom accords, and clean white musk bases — all designed to complement the active cosmetic ingredient story without overwhelming the product's efficacy positioning. If you want a proprietary custom fragrance — one developed exclusively for your brand — the process involves working with either the manufacturer's in-house perfumer or a third-party fragrance house. Custom fragrance development typically costs $500–$3,000 for an exclusive accord, with IFRA (International Fragrance Association) compliance documentation required. The fragrance must be tested for stability in the specific formula base, because fragrance components interact with emulsion systems, active ingredients, and packaging. This adds 4–8 weeks to your development timeline. Fragrance load in body milk typically runs 0.3%–1.5%. Higher loads can interact with kojic acid stability — some fragrance raw materials are pro-oxidant or shift pH, which accelerates kojic acid degradation and discoloration. Your cosmetic chemist should conduct a fragrance compatibility screen (typically a 4-week bench test at elevated temperature) before approving the final fragrance at production concentration. Fragrance allergen labeling is also a regulatory consideration. Under EU Cosmetics Regulation, 26 listed fragrance allergens must be declared on the label if present above 0.001% (leave-on) threshold. With the EU's evolving allergen framework (Regulation 2023/1545 expanding the list to over 80 allergens by 2025), ensure your fragrance supplier provides a full allergen declaration. For unscented or fragrance-free positioning — increasingly popular in the brightening category, especially for sensitive skin claims — your manufacturer should use a masking agent to neutralize the inherent odor of TXA and kojic acid (both have mild characteristic odors) without technically being a fragrance. AJ Cosmo Labs enables founders to specify fragrance preferences in their product brief inside the app and match with manufacturers who have in-house perfumers or established fragrance house partnerships.
How do I find a private label body milk manufacturer in South Korea or Asia for small brands?
South Korea is the most developed ecosystem globally for private label brightening body milk manufacturing, and it is particularly accessible to small brands due to the sheer density of OEM/ODM facilities concentrated in the Seoul Capital Area (Incheon, Suwon, Anyang) and in Chungcheongbuk-do province. Korean manufacturers pioneered many of the brightening actives used globally, including kojic acid derivatives, arbutin, and niacinamide blends, and many have long-standing experience with tranexamic acid formulations. The entry points for small brands sourcing from Korea are: Korean OEM/ODM trade shows (K-Beauty Expo, InterCHARM Korea), B2B platforms, agency-based sourcing services, and increasingly, app-based marketplaces like AJ Cosmo Labs where Korean and broader Asian manufacturers list their capabilities and MOQ ranges directly. When approaching a Korean manufacturer, prepare the following before initial contact: a product brief (desired active concentrations, target market, pack size, packaging preference, target COGS), reference products for texture and finish (water-thin lotion vs. thicker milk), fragrance direction, and your target MOQ and timeline. Korean OEMs respond fastest to founders who are specific and prepared — a vague inquiry gets a delayed or generic response. MOQs at Korean facilities for brightening body milk typically start at 300–500 units for existing formulas and 1,000–3,000 units for custom ODM development. Some smaller Korean studios (called 소공인 or small manufacturing ateliers) can work at 100–200 units for semi-custom projects, though quality and GMP standards vary more at this tier and require more rigorous vetting. Language and time zone are practical obstacles. Many mid-sized Korean OEMs have English-speaking export sales teams, but communication delays of 24 hours per email exchange are common. Using a platform that enables asynchronous messaging with translation support — as AJ Cosmo Labs does through its app — significantly reduces friction. Beyond Korea, Malaysia is a strong option for Halal-certified formulations (JAKIM certification), with a growing cluster of cosmetic contract manufacturers around Selangor and Kuala Lumpur. Thailand and the Philippines are developing hubs with lower labor costs but fewer facilities with full GMP-to-EU-standard credentials. China-based OEMs (Guangzhou is the primary hub) offer the lowest COGS but require more rigorous vetting for IP protection, raw material authenticity (especially for pharmaceutical-grade TXA), and regulatory documentation quality. Founders targeting the EU or UK market from Chinese OEMs need to invest particularly carefully in independent third-party audits.
