DIMETHICONE PEG-8 LAURATE.

Valuable / SKIN CONDITIONING

Dimethicone PEG-8 Laurate is a sophisticated silicone derivative that effectively conditions the skin by forming a smooth, protective barrier, locking in vital moisture. Beyond its skin-enhancing properties, it acts as a robust emulsifier, crucial for stabilizing diverse cosmetic formulations.

Summary

Emulsifying Skin Conditioning Surfactant

Science

Mechanism of Action

This ingredient functions by creating a smooth, vapor-permeable film on the skin's surface, which significantly contributes to moisture retention, preventing dryness and promoting a softer, more supple feel. Its silicone-based structure, enriched with polyethylene glycol (PEG) and lauric acid, delivers both emollient and hydrating benefits, and can temporarily minimize the appearance of fine lines. Additionally, it serves as a powerful emulsifier and surfactant, effectively reducing interfacial tension to ensure stable dispersion of oil and water components in formulations.

Stability

For optimal stability, formulations containing Dimethicone PEG-8 Laurate should maintain a pH between 5.5 and 8.5. If incorporated into hot-processed emulsions, it is crucial to add the ingredient once the temperature has dropped below 50°C (122°F) to preserve its functional integrity. It readily integrates into the water phase of formulations and can contribute to serum or cream textures.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has affirmed that dimethicone and its related polymers, including this ingredient, are safe for use in cosmetics under current practices when formulated to be non-irritating. While generally well-tolerated, with a low incidence of skin irritation or allergic reactions, individuals with particularly sensitive skin or known allergies are advised to perform a patch test. Data regarding safety for products that may be incidentally inhaled (e.g., via airbrush devices) are currently insufficient.
