Science
Mechanism of Action
Classified as an alkali-swellable emulsion (ASE) polymer, it undergoes a structural expansion upon neutralization with a base, creating a sophisticated thickening network. On the skin, it forms a cohesive, water-resistant film that reduces transepidermal water loss and improves the longevity of accompanying active ingredients.

Clinical Evidence
High confidence2.5%
Key findings
- 01 Demonstrated multifunctional capabilities as a fixative and rheology modifier, providing shear-thinning properties that improve application spreadability and emulsion stability.
Transparency
Dusting Analysis
As a functional texture enhancer rather than a primary active, use levels below 0.1% typically indicate a failure to provide meaningful structural benefits to the formulation.
The Formula
Formulation
Stability
Requires the addition of a neutralizing agent (such as NaOH or TEA) to activate its thickening properties and achieve maximum clarity.
Synergies
- Surfactants
- UV filters
- Alkaline actives
Conflicts
- High electrolyte concentrations
- Strongly cationic ingredients
- Low pH environments (<5.5)
