Compatibility

Works well with:
Glycerin Niacinamide Hyaluronic Acid Panthenol Allantoin Triethanolamine

Use caution with:
high concentrations of electrolytes cationic polymers propylene glycol at high levels

Must be neutralized with an alkaline agent such as triethanolamine, sodium hydroxide, or aminomethyl propanol to achieve full thickening and gelation; unactivated dispersion remains thin and acidic. High electrolyte (salt) concentrations significantly reduce viscosity and can collapse the gel network. Cationic polymers such as polyquaternium compounds can interact with the anionic polymer backbone, causing flocculation or viscosity loss.

Formulation notes

Acrylates/C10-30 Alkyl Acrylate Crosspolymer is a hydrophobically modified, crosslinked polyacrylic acid polymer used primarily as a rheology modifier and emulsion stabilizer. Its pendant long-chain alkyl groups allow it to stabilize oil-in-water emulsions at low use levels without additional emulsifiers, and it imparts a light, non-tacky skin feel. It is widely used in lotions, gels, sunscreens, and creams; because it is anionic and neutralization-dependent, formulators must account for pH and ionic strength early in the formulation design process.
