PHENOXYPROPANEDIOL.

Insufficient Data CAS 538-43-2 / SOLVENT

Phenoxypropanediol is a versatile ingredient functioning as a solvent, emollient, and preservative in skincare formulations. Its unique dual hydrophobic and hydrophilic characteristics enable stable oil-in-water emulsions, thereby enhancing product integrity and sensory feel. This multifunctional nature also supports improved delivery of other active ingredients to the skin.

Solvent Emollient Preservative Antimicrobial Delivery Enhancer

Science

Mechanism of Action

Phenoxypropanediol operates through several mechanisms: it acts as a solvent to dissolve various compounds, provides a softening effect as an emollient, and inhibits microbial proliferation as a preservative. Its amphiphilic molecular structure, featuring both water-attracting and oil-attracting properties, effectively couples immiscible phases to stabilize cosmetic emulsions. This characteristic further facilitates enhanced skin penetration and bioavailability for co-formulated active ingredients.
