Trimethylsiloxysilicate

Trimethylsiloxysilicate is a highly crosslinked silicone resin that is heavily relied on to protect the product from rinsing away too easily with water, sweat or friction.

Trimethylsiloxysilicate, often found listed in the ingredients of your favorite skincare and beauty products, is a silicone compound renowned for its unique properties. This ingredient, first introduced to the cosmetic world in the 1950s, has become a staple in various formulations due to its multifaceted benefits.

Traditionally, it's been widely used in industry for its antifoaming capabilities, and in recent years, its remarkable traits have found favor in the skincare sector. This silicone derivative excels in providing a moisturizing barrier on the skin's surface, contributing to its health and vitality in ways you might not have anticipated

One of the features of Trimethylsiloxysilicate in skincare is its role as an occlusive moisturizer. It forms a breathable, non-comedogenic layer on the skin, preventing water loss and keeping your skin hydrated throughout the day.

Moreover, its emollient properties enhance the skin's surface, creating a smooth and soft complexion. 

Trimethylsiloxysilicate can also reduce foaming when added to oil-in-water emulsions that suffer from unwanted foaming.

Trimethylsiloxysilicate has several benefits, which contribute to its widespread use in skincare products:

1. Moisturizing (Occlusive): As an occlusive agent, Trimethylsiloxysilicate forms a protective barrier on the skin's surface. This prevents the evaporation of water from the skin's surface (TEWL), helping maintain skin hydration and softness.

2. Emollient: As an emollient, Trimethylsiloxysilicate helps to smooth and soften the skin, improving its texture and feel.

Trimethylsiloxysilicate's safety in skincare has been extensively studied. The Cosmetic Ingredient Review (CIR), an independent body that assesses the safety of ingredients used in cosmetics, concluded that Trimethylsiloxysilicate is safe for use in skincare and cosmetics.
