Silicones are a family of synthetic polymers derived from silica, methanol, and water. They have been added to more than 50% of beauty product launches in the last decade to provide a "waterproof" effect, form a moisture-retaining film, and improve pigment dispersion.
Silicones and health
Siloxanes —a subtype widely used in shampoos, creams, and makeup—are the most concerning category. Several agencies warn of their potential endocrine disruptors , affecting fertility and hormonal balance.
Silicones and the environment
Annual production of methylsiloxanes is around 8–10 million tonnes . They are highly persistent and bioaccumulative : they take decades to degrade and accumulate in the marine food chain.
How to detect silicones on the label
Look for these endings and avoid products that include them:
- Words ending in -siloxane
- Cyclomethicone or Cyclopentasiloxane
- Dimethicone , Dimethiconol or Amodimethicone
At TEIA, no product contains silicones; our formulas are 100% free of these compounds.
