What it is
A modified silicone molecule combined with stearic acid (a fatty acid from plant or animal sources). It is a semi-synthetic ingredient designed to provide emollient and skin-conditioning benefits.
How it works
It forms a thin, breathable film on the skin that reduces water loss and gives a smooth, velvety feel. It also helps other ingredients spread evenly and can improve the stability of emulsions (mixtures of oil and water).
Pros
Silky texture
Creates a smooth, velvety feel on the skin that many people find pleasant and luxurious.
Low irritation risk
Rarely causes stinging or redness, making it suitable for sensitive skin.
Cons and cautions
Silicone-based
Some people prefer to avoid silicones for personal or environmental reasons, though this ingredient is generally considered safe.
Potential buildup
In hair products, it can accumulate over time, requiring a clarifying shampoo to remove.
Best for
- People with dry or normal skin looking for a smooth finish
- Anyone who enjoys a silky, non-greasy texture in their products
Use caution if
- Those who prefer silicone-free formulations
- Individuals with very oily skin who may find silicones too heavy
