Ammonium Acryloyldimethyltaurate/VP Copolymer

Product Description

Ammonium Acryloyldimethyltaurate/VP Copolymer is a versatile, pre-neutralized synthetic polymer that functions as a gelling agent for aqueous systems and a texturizer for oil-in-water emulsions. Known in the industry for creating the sophisticated "melting" sensation on the skin, it offers a superior sensory profile compared to traditional carbomers. Upon application, the polymer structure breaks down immediately, releasing moisture for a refreshing, non-sticky, and velvety after-feel. Its standout feature for B2B formulators is its ability to stabilize oils without the use of HLB-based emulsifiers. This allows for the creation of "emulsifier-free" cream-gels that are lightweight, fast-absorbing, and gentle on the skin. Additionally, it exhibits excellent compatibility with organic solvents like ethanol, making it a robust choice for formulations containing alcohol.

Product Uses

This copolymer is the gold standard for creating modern, lightweight textures favored in the premium skincare market. It is the primary thickener for Gel-Creams and oil-free hydrators that require a fresh, watery application experience. In Sun Care, it is utilized to stabilize UV filters while reducing the greasy feel of sunscreens. Due to its high alcohol tolerance, it is extensively used in hand sanitizers and after-shave balms to provide thickening without precipitation. It is also an excellent stabilizing agent for serums containing difficult-to-suspend actives, ensuring a consistent and aesthetically pleasing product appearance.

Formulation Suggestions

Ammonium Acryloyldimethyltaurate/VP Copolymer is user-friendly and cold-processable. As a pre-neutralized powder, it requires no neutralization step with alkali. It can be added to the oil phase (preferred for ease of dispersion) or the water phase under agitation. It swells quickly to form a gel. However, formulators must note that this polymer is sensitive to electrolytes (salts). High concentrations of salt or ionic actives can cause a loss of viscosity; in such cases, it should be paired with other thickeners. It is stable across a wide pH range (4.0 to 9.0). Recommended usage levels are 0.5% to 1.2% for gelling and 0.1% to 0.5% as a co-stabilizer. Our recommendations are for reference only; please follow the advice of your formulator for actual production.
