PEG/PPG-12/12 DIMETHYLSILOXYSILICATE

Description

PEG/PPG-12/12 Dimethylsiloxysilicate is a versatile silicone-based polymer used in various cosmetic and skincare formulations. This compound is primarily recognized for its film-forming and water-resistant properties, making it an essential ingredient in long-wearing makeup products and sun protection formulas. Its molecular structure combines both hydrophilic (water-loving) and hydrophobic (water-repelling) components, allowing it to create a flexible, breathable barrier on the skin's surface.

In skincare applications, PEG/PPG-12/12 Dimethylsiloxysilicate functions as an emollient and texture enhancer, contributing to a smooth, silky feel upon application. It aids in improving the spreadability of formulations and can help to reduce the greasy or tacky sensation often associated with high-oil content products. This ingredient is particularly valuable in water-resistant sunscreens, as it helps to maintain the integrity of the UV protection even in humid or aquatic environments.

While generally considered safe for topical use, individuals with silicone sensitivities should exercise caution. As with any cosmetic ingredient, patch testing is recommended to ensure compatibility with individual skin types. PEG/PPG-12/12 Dimethylsiloxysilicate is often found in foundations, lip products, and other cosmetics requiring extended wear time or water resistance.
