What it is
A synthetic silicone polymer modified with a phenyl group and a lauryl chain, designed to provide emollient and film-forming properties.
How it works
It forms a thin, breathable film on the skin or hair surface, reducing water loss and creating a smooth, non-greasy barrier. This improves the texture of products and helps other ingredients spread evenly.
Pros
Silky texture
Creates a smooth, velvety feel on skin and hair without greasiness, improving the sensory experience of products.
Low irritation potential
Generally well-tolerated by most skin types, including sensitive skin, with a low risk of clogging pores.
Cons and cautions
Synthetic origin
As a man-made silicone, it may not align with natural or minimalist skincare preferences.
Potential buildup
On hair, repeated use without thorough cleansing can lead to buildup, making hair feel heavy or dull.
Best for
- People with normal to oily skin who want a smooth finish
- Those looking for a lightweight primer or makeup base
Use caution if
- Individuals who prefer silicone-free or all-natural formulations
- Those with very dry skin who may need richer occlusives
