Stearyl Octyldodecyl Citrate Crosspolymer
What is Stearyl Octyldodecyl Citrate Crosspolymer?
Stearyl Octyldodecyl Citrate Crosspolymer is a synthetic crosspolymer derived from citric acid esterified with stearyl and octyldodecyl alcohol chains, functioning primarily as a film-forming agent and texture enhancer in skincare formulations. It creates a smooth, non-greasy film on the skin that improves product spreadability and provides a sensorial benefit, often used in sunscreens, moisturizers, and primers to boost SPF performance and water resistance. This ingredient is valued for its stability and ability to modify the rheology of emulsions without compromising the overall formula integrity.
Roles in Formulation
This ingredient serves the following purposes in cosmetic formulations:
Emollient
Softens and smooths skin by filling in surface roughness and improving slip; can also help reduce moisture loss when paired with occlusives and film formers.
Skin conditioning agent
Maintains skin softness, smoothness, and flexibility.
Viscosity controlling agent
Adjusts thickness to the desired level for stability and usability, improving dispensing, suspension, and texture across many formulation types.
Film former
Creates a continuous film on skin or hair to improve wear, water resistance, transfer resistance, shine, or hold in sunscreens, makeup, and styling products.
