Polyglyceryl
Polyglyceryl refers to a family of non-ionic surfactants and emulsifiers made by the polymerization of glycerol units. Depending on the number of glycerol units (e.g., Polyglyceryl-2, -3, -6, -10) and fatty acid esterification (e.g., laurate, oleate, stearate), they offer different emulsifying and solubilizing properties. These compounds are biodegradable, mild, and skin-friendly, making them ideal for use in cosmetics, food, pharmaceuticals, and personal care products. Polyglyceryl esters are often chosen in natural and organic product formulations due to their origin and non-toxic profile.
Polyglyceryl
Primary Uses
- Cosmetics & Personal Care Products
- Serve as emulsifiers in creams, lotions, sunscreens, serums, and cleansers.
- Excellent for oil-in-water (O/W) and water-in-oil (W/O) emulsions depending on HLB value.
- Provide a light, non-greasy feel, making them suitable for facial care and sensitive skin products.
- Common in natural, vegan, and clean-label cosmetic formulations.
- Food Industry
- Used as food-grade emulsifiers and dispersing agents (especially Polyglyceryl esters of fatty acids).
- Help stabilize emulsions in sauces, dressings, ice cream, and non-dairy creamers.
- Improve mouthfeel and texture in reduced-fat or low-calorie foods.

- Pharmaceutical Formulations
- Act as emulsifiers and solubilizers for oral suspensions, creams, and suppositories.
- Improve the solubility and delivery of active pharmaceutical ingredients (APIs).
- Used in topical preparations to enhance absorption and skin feel.
- Baby Care & Sensitive Skin Products
- Due to their non-irritating, non-sensitizing nature, they are widely used in baby lotions, creams, and shampoos.
- Ideal for eczema and allergy-prone formulations.
Secondary Uses
- Oral Care
- Used as mild emulsifiers and solubilizers in toothpastes, mouthwashes, and dental gels.
- Makeup & Color Cosmetics
