DROMETRIZOLE TRISILOXANE ●
TL;DR. This ingredient is an oil-soluble UV filter used in sunscreens and daily skin-care products to absorb UV radiation, especially across UVA with added UVB support. It also helps improve photostability when paired with other UV filters.
What does DROMETRIZOLE TRISILOXANE do in a cosmetic formula?
This ingredient is an oil-soluble UV filter used in sunscreens and daily skin-care products to absorb UV radiation, especially across UVA with added UVB support. It also helps improve photostability when paired with other UV filters.
Is DROMETRIZOLE TRISILOXANE clean?
From a clean-beauty perspective, it has regulatory acceptance in several markets and is generally used for performance rather than sensory claims, but it is a synthetic silicone-based filter and is often outside stricter clean-standard lists. Sensitization is not a major known issue, but brand standards may flag it because of its synthetic origin and environmental persistence questions.
Is DROMETRIZOLE TRISILOXANE sustainable?
This material is synthetically made and is not considered readily biodegradable. Its silicone-linked structure raises persistence considerations in aquatic environments, so its sustainability profile is weaker than readily biodegradable plant-derived or mineral ingredients.
Is DROMETRIZOLE TRISILOXANE COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic standards as a UV filter. Its synthetic feedstock, limited biodegradability, and persistence profile place it in weak alignment with Green Chemistry preferences.
How does DROMETRIZOLE TRISILOXANE work chemically?
The molecule is an oil-soluble aromatic UV absorber attached to a short silicone segment, which improves compatibility with oil phases and helps it remain photostable under sunlight exposure. In regions where it is authorized, it is typically allowed in sunscreen formulas up to 15%, and it is commonly co-formulated with other filters to broaden and balance UV coverage.
