Emollient Emulsifying Surfactant/Cleansing Viscosity Controlling Film-forming

Science

Mechanism of Action

This dimethicone copolymer acts as an emollient, forming a protective film on the skin's surface to enhance smoothness and conditioning. It also serves as an emulsifier and surfactant, facilitating the homogeneous blending of immiscible liquids and contributing to cleansing properties. Furthermore, it functions as a film-former and can influence product viscosity.

CIR Status
Not reviewed
Sensitization risk Unknown

No direct safety assessment by major regulatory bodies such as CIR, SCCS, or FDA was identified for DEA PG-PROPYL PEG/PPG-20/20 DIMETHICONE. While many PEG and PPG compounds are generally considered safe when properly formulated, the 'DEA' (diethanolamine) component in the name is a critical consideration. DEA and its salts are explicitly prohibited in cosmetic products under EU Regulation 1223/2009/EC (Annex II/411). However, other DEA derivatives are permitted, provided the free DEA content does not exceed 0.5% by weight.

Our Assessment

Verdict

Questionable

While offering valuable emollient, emulsifying, and film-forming properties, this ingredient's 'DEA' component raises significant regulatory and safety concerns in certain regions, necessitating strict formulation control and careful consideration due to the absence of direct safety reviews.
