DIMETHICONE PEG-7 LACTATE.

Valuable / HAIR CONDITIONING, SKIN CONDITIONING

DIMETHICONE PEG-7 LACTATE is an amphiphilic silicone polymer expertly designed to enhance skin hydration and refine texture. It effectively forms a protective barrier, reducing trans-epidermal water loss while simultaneously acting as an emollient to smooth and soften the skin. Its water-dispersible nature allows for versatile application across various skincare and hair care formulations.

Science

Mechanism of Action

This ingredient functions as an amphiphilic silicone polymer, incorporating both water-soluble (PEG) and silicone-soluble (Dimethicone) components. The Dimethicone portion establishes a protective, hydrophobic film on the skin's surface, which significantly minimizes trans-epidermal water loss, effectively locking in moisture and improving skin hydration. This barrier additionally offers a degree of protection against environmental irritants. As an emollient, it smoothes the skin's texture, contributing to a softer feel and diminished appearance of fine lines. The PEG-7 component ensures its water-dispersibility, making it suitable for a diverse array of cosmetic formulations, including rinse-off products. Furthermore, it acts as a hair conditioning agent, promoting manageability, suppleness, softness, and shine.

Stability

Optimal formulation stability for similar PEG-Dimethicone ingredients is typically observed within a pH range of 5.5 to 8.5. Hydrolysis rates demonstrate increased stability at higher pH; for example, at 1% active, 20% hydrolysis occurred in 45 days at pH 5, compared to 86 days at pH 8. Therefore, maintaining a pH of 5.0 or above is generally recommended for robust storage stability. The PEG moiety enables water-dispersibility and solubility in water and alcohols.

Conflicts

  • Carbomer-based thickeners (potential disruption due to lactate component)
  • Certain non-polar organic and silicone solvents (may result in insolubility for PEG-Dimethicone)
  • High concentrations of humectants (risk of contributing to a sticky or tacky skin feel)

Safety

Safety Profile

CIR Status
Safe as used
Max tested
85%
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that Dimethicone and its related polymers, including PEG-Dimethicone variants, are safe for use in cosmetics when formulated to be non-irritating. Due to its substantial molecular weight, significant dermal absorption is considered unlikely. Clinical and animal studies on Dimethicone indicate no acute toxicity, minimal dermal irritation, and no sensitization, even at concentrations up to 79% (undiluted) or 5.0% in human patch tests. The FDA lists Dimethicone as a skin protectant. While PEG compounds may carry a theoretical risk of manufacturing contaminants, Moumoujus rigorously selects suppliers to ensure product purity and safety. No specific SCCS opinion for DIMETHICONE PEG-7 LACTATE was found, though Dimethicone itself has been reviewed.
