C12-13 PARETH-4.

Valuable CAS 66455-14-9 / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

A non-ionic emulsifying agent that enables stable oil-in-water formulations by reducing interfacial tension between incompatible phases. This synthetic surfactant excels at creating smooth, uniform textures in creams and cleansers while maintaining exceptional stability across varying pH conditions. Its gentle profile makes it suitable for sensitive skin formulations despite being a functional workhorse ingredient.

emulsifying surfactant/cleansing

Science

Functions as an O/W emulsifier with an HLB value of 9.5-9.7, reducing surface tension between oil and water phases to create stable emulsions. Additionally enhances pigment wetting and dispersion while providing mild cleansing properties through its surfactant structure.

Key findings

  1. 01 Demonstrated stability and non-irritating properties as emulsifier in topical formulations, with analogous compounds showing rapid dermal absorption but low systemic toxicity (LD50 > 2000 mg/kg)

Transparency

Not commonly dusted

As a functional emulsifier rather than active ingredient, not typically subject to dusting practices


The Formula
