POTASSIUM C9-15 ALKYL PHOSPHATE.

Valuable / SURFACTANT - CLEANSING

POTASSIUM C9-15 ALKYL PHOSPHATE is a mild foaming surfactant and emulsifier, essential for creating stable, well-distributed cosmetic formulations. It efficiently cleanses the skin while imparting a smooth after-feel, making it suitable for a diverse range of personal care products.

Summary

Surfactant Cleansing Agent Emulsifier

Science

Mechanism of Action

This ingredient functions primarily as a surfactant by significantly reducing the surface tension of liquids, which facilitates the stable blending of immiscible substances like oil and water. It acts as a washing-active and cleansing agent, aiding in the removal of fat and soil particles from the skin and hair, while producing a dense, lubricious foam for an enhanced sensorial experience.

Dusting Analysis

Not commonly dusted

POTASSIUM C9-15 ALKYL PHOSPHATE is a fundamental functional ingredient rather than an active typically 'dusted' at trace amounts. Its surfactant and emulsifying properties require use at concentrations beyond a dusting threshold to be effective.

Stability

This ingredient is versatile, being usable in both anhydrous and aqueous formulation systems. For related alkyl-phosphate potassium salts, increasing pH and neutralization temperature can lead to a decrease in emulsion particle size. Formulations can generally be prepared at either elevated or room temperatures.
