Compatibility

Works well with:
Glycerin Carbomer Xanthan Gum Sodium Hyaluronate Niacinamide Cetyl Alcohol

Use caution with:
High concentrations of electrolytes

Polyglyceryl-10 Stearate is a gentle, hydrophilic emulsifier with a high HLB value (approximately 14-16), making it well-suited for oil-in-water emulsions and light lotions. It is generally compatible with most cosmetic ingredients but can be sensitive to very high electrolyte concentrations, which may disrupt emulsion stability. It pairs well with co-emulsifiers of lower HLB values to create stable, balanced emulsion systems.

Formulation notes

Polyglyceryl-10 Stearate is a naturally-derived, non-ionic emulsifier produced by esterifying polyglycerol-10 with stearic acid, commonly sourced from vegetable oils. It is valued for its mild skin feel, biodegradability, and suitability for clean-beauty and natural formulations. It is considered safe for most skin types including sensitive skin, and is often found in lightweight creams, serums, and lotions.
