Hydroxypropyl Cyclodextrin Trihydroxystearin ●
TL;DR. This ingredient is mainly used as an encapsulating, odor-binding, and stabilizing material for small oil-loving molecules such as fragrance components, malodor compounds, or select actives. Its fatty portion can also improve oil-phase compatibility and add light structuring or film feel.
What does Hydroxypropyl Cyclodextrin Trihydroxystearin do in a cosmetic formula?
This ingredient is mainly used as an encapsulating, odor-binding, and stabilizing material for small oil-loving molecules such as fragrance components, malodor compounds, or select actives. Its fatty portion can also improve oil-phase compatibility and add light structuring or film feel.
Is Hydroxypropyl Cyclodextrin Trihydroxystearin clean?
From a clean-beauty perspective, it is not a common restricted-list ingredient and is generally expected to have low sensitization potential. The main caveat is that it is a chemically modified material, so it may not fit the strictest definitions of minimally processed natural ingredients.
Is Hydroxypropyl Cyclodextrin Trihydroxystearin sustainable?
This material is typically based on a starch-derived sugar structure combined with a vegetable-oil-derived fatty ester, with an added synthetic modification step. Its components are generally more biodegradable than silicone or fluorinated film formers, but the processing route is less simple than for unmodified plant oils or waxes.
Is Hydroxypropyl Cyclodextrin Trihydroxystearin COSMOS-approved?
This ingredient is not a straightforward COSMOS-organic fit because it is chemically modified, and public confirmation for broad COSMOS-natural acceptance is limited. It has partial Green Chemistry alignment through renewable feedstock content and expected biodegradability, balanced by the synthetic modification step.
How does Hydroxypropyl Cyclodextrin Trihydroxystearin work chemically?
The molecule combines a cyclic sugar-like cavity with a lipophilic fatty ester domain, giving it both inclusion-complex behavior and better compatibility with oil phases. It is generally stable across typical cosmetic pH ranges, with the saturated fatty portion offering better oxidation resistance than unsaturated plant oils.
