PEG-12 CARNAUBA.

Valuable CAS 223705-69-6 / EMULSION STABILISING

PEG-12 Carnauba is a specialized, polar derivative of carnauba wax, engineered through esterification with polyethylene glycol. This modification imbues the wax with strong hydrophilic properties, enabling it to function as a non-ionic self-emulsifying agent crucial for stable oil-in-water formulations. Beyond its emulsifying capabilities, it contributes to superior product texture, feel, and moisturizing benefits.

Science

Mechanism of Action

This ingredient operates primarily as a non-ionic self-emulsifying wax, forming and stabilizing oil-in-water emulsions by bridging oil and water phases. On the skin, it forms a protective film, which aids in moisturizing and preventing lipid and color ingredient migration. Its unique structure contributes to enhanced texture and gloss in solid products, promotes even pigment dispersion, and imparts a desirable non-greasy feel with added slip, while also allowing for the seamless integration of water-soluble actives.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has deemed both Carnauba Wax and the broader class of Polyethylene Glycols (PEGs) safe for cosmetic use under current practices. While PEG-12 Carnauba specifically lacks a dedicated CIR report, SCCS opinion, or FDA status, its base components are well-tolerated. A previous caution regarding PEG use on compromised skin was re-evaluated and removed in 2010, indicating minimal safety concerns, and general PEGs are not microbiologically sensitive.
