Polyhydroxystearic Acid
- INCI:
- Polyhydroxystearic Acid
- Also known as:
- PHSA
Polymeric pigment dispersant for oil-based media, key in fluid foundations and liquid lipsticks. It coats the particles of pigments and inorganic filters, improving milling, dispersion stability, and color uniformity. It helps prevent sedimentation and flocculation over the product's shelf life.
Functions
Typical applications
- Fluid foundations
- Liquid lipsticks
- Pigment dispersions
- Sunscreens with inorganic filters

Trimethylsiloxysilicate
Film-forming silicone resin used in long-wear makeup formulations. It is associated with transfer- and rub-resistant finishes in lipsticks, foundations, and eyeliners. It is usually incorporated dissolved in the volatile solvent phase of the formula.
Carbomer
Carbomer
Cross-linked acrylic polymer, the global standard for thickening and stabilizing gels and emulsions. Once neutralized, it produces transparent gels with a characteristic rheology, and it suspends particles and actives with great efficiency at low use levels.
Guar Hydroxypropyltrimonium Chloride
Guar Hydroxypropyltrimonium Chloride
Cationic derivative of guar gum used as a deposition conditioner in cleansing systems. It improves wet combability, softens the skin in shower gels, and contributes to the viscosity of the formula.
Hydroxyethyl Cellulose
Hydroxyethylcellulose
Nonionic, water-soluble cellulosic thickener, a standard in water-based architectural paints for viscosity control, water retention, and storage stability. It provides good leveling and spatter resistance during application. It is also used as a rheology modifier in gels and personal care products.
