CELLULOSE ACETATE PHTHALATE

Description

Cellulose Acetate Phthalate (CAP) is a pharmaceutical excipient widely used in the formulation of oral and topical medications. This synthetic polymer is derived from cellulose and modified with acetate and phthalate groups, giving it unique properties beneficial for drug delivery systems. CAP is primarily valued for its pH-dependent solubility, making it an excellent enteric coating material for tablets and capsules.

In skincare formulations, CAP serves multiple functions. It acts as a film-forming agent, creating a protective barrier on the skin's surface that can help retain moisture and shield against environmental stressors. Its pH-sensitive nature allows for controlled release of active ingredients, potentially enhancing their efficacy and reducing irritation. CAP also exhibits emulsifying properties, aiding in the stabilization of oil-in-water formulations.

The polymer's compatibility with various cosmetic ingredients makes it versatile in skincare applications. It can be incorporated into serums, creams, and sunscreens to improve texture and increase product stability. However, formulators must consider potential sensitivities to phthalates when using CAP in cosmetic products, as regulatory guidelines may vary by region.
