10-Hydroxydecanoic Acid ●
TL;DR. This ingredient is used mainly as a skin-conditioning and sebum-balancing active, especially in formulas aimed at oily or blemish-prone skin. It may also support mild antimicrobial preservation strategies, but it is not typically used as a standalone preservative.
What does 10-Hydroxydecanoic Acid do in a cosmetic formula?
This ingredient is used mainly as a skin-conditioning and sebum-balancing active, especially in formulas aimed at oily or blemish-prone skin. It may also support mild antimicrobial preservation strategies, but it is not typically used as a standalone preservative.
Is 10-Hydroxydecanoic Acid clean?
From a clean-beauty perspective, this ingredient is generally low-friction, with no major restricted-list controversy and low expected irritation at typical cosmetic levels. As with many acid-functional materials, comfort depends on concentration, formula pH, and the overall barrier condition of the user.
Is 10-Hydroxydecanoic Acid sustainable?
This material is a biodegradable fatty-acid derivative that can be made from renewable lipid feedstocks, though commercial sourcing depends on the supplier. Its environmental profile is generally favorable compared with persistent silicone or fluorinated materials.
Is 10-Hydroxydecanoic Acid COSMOS-approved?
It can be compatible with COSMOS-natural and COSMOS-organic formulas when sourced and processed through permitted routes, with supplier documentation needed for final certification. It aligns reasonably well with Green Chemistry because it is a small biodegradable fatty-acid derivative and can come from renewable feedstocks.
How does 10-Hydroxydecanoic Acid work chemically?
The molecule is a 10-carbon fatty acid bearing a terminal hydroxyl group and a carboxylic acid group, giving it both lipid affinity and limited water compatibility depending on pH and salt form. It is usually formulated at low active levels in sebum-control blends, and its acid group means solubility, skin feel, and activity can shift as pH moves across the mildly acidic to neutral range.
