Science & Benefits

A hydrophobically modified alkali-soluble emulsion (HASE) polymer. It acts as a primary stabilizer in formulas containing high levels of surfactants or electrolytes. Beyond thickening, it contributes to a 'velvety' skin feel upon application. It is zero-comedogenic and zero-irritant. For acne-prone users, this polymer is a strategic functional ingredient because it allows for the inclusion of mineral-rich actives or salt-based humectants without causing the product to thin out or lose its hydrating efficacy on the skin surface.
