DIMETHICONE PEG-3 LAURATE.

Valuable / FILM FORMING

DIMETHICONE PEG-3 LAURATE is a versatile silicone-based emollient that forms a lightweight, protective film on the skin, enhancing its texture and hydration while providing conditioning benefits.

Summary

Emulsifying Emollient Hair Conditioning Skin Conditioning Surfactant

Science

Mechanism of Action

This ingredient functions by creating a smooth, protective occlusive layer on the skin's surface, which effectively seals in moisture and prevents dehydration, resulting in a softer, more supple feel. Its film-forming properties also offer a temporary smoothing effect on fine lines and wrinkles. Additionally, it serves as a skin conditioner, emollient, and emulsifier, capable of mitigating skin irritation.

Stability

To maintain ingredient integrity, avoid heating PEG-8 Dimethicone above 50°C (125°F) when incorporating into the water phase, and ensure its addition to emulsions occurs after temperatures have dropped to 50°C. For Lauryl PEG-8 Dimethicone, heat exposure should not exceed 80°C. The optimal pH range for similar ingredients like PEG-8 Dimethicone typically aligns with neutral conditions.

Safety

Safety Profile

CIR Status
Safe as used
Max tested
10%
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has deemed Dimethicone, Methicone, and related substituted-methicone polymers safe for use in cosmetic products, attributing their safety to large molecular weight limiting significant skin absorption. A maximum concentration of 10% was noted for a similar ingredient, PEG/PPG-18/18 Dimethicone, in reported cosmetic applications. While Lauryl PEG-8 Dimethicone is generally recognized as safe by European regulatory bodies, it is important to note that PEG-containing components such as PEG-12 Dimethicone may potentially harbor impurities like ethylene oxide and 1,4-dioxane. Therefore, products containing PEGs are advised against use on compromised or irritated skin. Specific data regarding the topical application of Dimethicone PEG-8 Laurate during pregnancy and breastfeeding is currently unavailable, thus professional medical consultation is recommended.
