Use caution with:
High concentrations of electrolytes Cationic surfactants Polyquaternium polymers
Sodium Acrylate Copolymer is sensitive to high electrolyte concentrations, which can disrupt its thickening network and cause viscosity loss or syneresis. It is generally incompatible with cationic polymers and surfactants due to charge interactions that can cause precipitation or gelation. When formulating with salts or ionic actives, gradual addition and testing are recommended.
Formulation notes
Sodium Acrylate Copolymer is an anionic synthetic polymer used primarily as a rheology modifier and thickener in aqueous cosmetic systems such as serums, gels, and lotions. It provides clear to translucent gels with good skin feel and can contribute mild emulsifying properties in some formulations. It is generally considered safe for cosmetic use and does not require neutralization to activate, unlike traditional carbomers.
