Information

Polyhydroxystearic Acid is a multifunctional plant-derived compound used in cosmetics and skincare formulations. It is derived from hydroxystearic acid, a modified fatty acid, and is valued for its ability to stabilize formulations, improve texture, and contribute to the performance of other ingredients.

Where does it come from?

Polyhydroxystearic Acid is produced from castor oil or other plant-based fatty acids through a process that compounds hydroxystearic acid. The result is a biodegradable, plant-derived compound that is compatible with modern “clean beauty” standards.

What are the benefits?

BIODEGRADABLE GENTLE STABILIZING

What are the benefits?

  • Stabilizes formulations – minimizes separation in emulsions and suspensions.
  • Texture – creates a smooth, spreadable feel without greasiness.
  • Pigments – used in makeup and tinted skincare to keep pigments evenly dispersed.
  • SPF performance – promotes the uniform distribution of mineral UV filters like zinc oxide or titanium dioxide.
  • Biodegradable & plant-derived – aligns with eco-friendly formulation goals.

How is it used in our products?

Polyhydroxystearic Acid is used in Serum Hydroxytyrosol Skin Tint and Serum Concealer from OLIVE ROSE. It is included in our pigment-containing formulations to keep particles evenly distributed and stable. It also enhances the sensory profile of creams, making them feel smoother and easier to spread. With mineral sunscreens ingredients especially, it plays a critical role in ensuring even coverage, better skin adherence and product aesthetics.
