PEG/PPG-20/20 PHENYLISOPROPYL CAPRYLYL DIMETHICONE.

Valuable / EMULSION STABILISING, HAIR CONDITIONING, SKIN CONDITIONING

PEG/PPG-20/20 Phenylisopropyl Caprylyl Dimethicone is a multifaceted silicone polymer designed to enhance cosmetic formulations. It acts primarily as a skin and hair conditioner, delivering a smooth feel and improving manageability. Beyond its conditioning properties, it functions as an emulsion stabilizer and texturizer, contributing to product efficacy and aesthetic.

Science

Mechanism of Action

This ingredient functions as an emollient, smoothing and softening the skin's surface. As a conditioning agent, it improves the tactile qualities of cosmetic products and enhances hair texture, making it more manageable and lustrous. It also serves as a surfactant and emulsion stabilizer, facilitating the homogeneous blending of oil and water phases, thereby enhancing product stability. Furthermore, it acts as a texturizer and thickener in oil-in-water emulsions, imparting a desirable skin feel and improving the water-resistance of sunscreens. It exhibits additional roles as a solvent and a broad-spectrum antimicrobial.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Moderate

Generally recognized as safe for cosmetic use, though a patch test is advisable for individuals with sensitive skin. While PEGs and PPGs typically exhibit good skin tolerance, some concerns regarding their solubility, toxicity, persistence, and bio-accumulation have led to their inclusion on 'orange lists' for further polymer research. A Safety Data Sheet indicates it is not considered toxic, carcinogenic, mutagenic, teratogenic, or a reproductive toxin. Acute oral, skin, ocular tolerance, and phototoxicity effects are not anticipated. However, the SDS does note 'possible skin dryness/irritation if over-exposed' and the potential for sensitivity development.
