Phenyltrimethicone ●
TL;DR. This ingredient is a silicone-based conditioning agent and emollient that adds slip, softness, shine, and a light film to hair and skin formulas. It is especially valued for gloss and a silky, non-greasy feel.
What does Phenyltrimethicone do in a cosmetic formula?
This ingredient is a silicone-based conditioning agent and emollient that adds slip, softness, shine, and a light film to hair and skin formulas. It is especially valued for gloss and a silky, non-greasy feel.
Is Phenyltrimethicone clean?
From a clean beauty perspective, this ingredient has low direct irritation potential but is often flagged because it is a synthetic silicone with limited biodegradability. Many clean standards restrict or exclude this material due to persistence concerns rather than acute skin-safety concerns.
Is Phenyltrimethicone sustainable?
This material is made from mineral-derived silicon chemistry combined with petrochemical inputs. It is not readily biodegradable and may persist in wastewater, sludge, or sediment depending on disposal and treatment conditions.
Is Phenyltrimethicone COSMOS-approved?
This ingredient is not permitted under COSMOS-natural or COSMOS-organic standards. Its Green Chemistry fit is weak because it relies on nonrenewable processing routes and has limited biodegradability despite being chemically stable in finished formulas.
How does Phenyltrimethicone work chemically?
The molecule has a silicon-oxygen backbone with methyl and aromatic side groups, which increases refractive index and helps create high shine. It is typically used around 0.5% to 5% in hair and skin products, is hydrophobic and broadly pH-stable, and usually needs emulsifiers or dispersing systems in water-based formulas.
