Polyglyceryl Extra Pure
SHORT DESCRIPTION
Polyglyceryl Extra Pure refers to a high-purity class of non-ionic surfactants and emulsifiers derived from glycerol units. These compounds are widely used in cosmetics, pharmaceuticals, and food formulations due to their excellent skin compatibility, emulsifying properties, and biodegradability.
Polyglyceryls come in various forms (e.g., Polyglyceryl-3, Polyglyceryl-6, Polyglyceryl-10), each offering different levels of hydrophilicity and emulsifying strength. In cosmetics, they help create stable oil-in-water emulsions, ideal for lotions, creams, cleansers, and sunscreens. In pharmaceuticals, their non-toxic and non-irritating nature makes them suitable carriers for active ingredients. In food products, they function as safe emulsifiers and stabilizers, supporting clean-label and natural product development.
This extra pure grade ensures low impurity levels, minimal odor, and consistent performance, making it ideal for sensitive applications. Store tightly sealed in a cool, dry place away from heat and light to maintain its stability and quality.
USES
Primary Uses
- Cosmetic & Personal Care Industry:
- Used as a mild, non-ionic emulsifier in skincare and haircare products.
- Common in natural and organic formulations due to its biodegradability and plant-derived origin.
- Helps stabilize oil-in-water emulsions in lotions, serums, creams, and sunscreens.
- Provides skin-conditioning effects and improves spreadability of cosmetic formulations.
- Food Industry:
- When food-grade, it serves as an emulsifying agent in baked goods, sauces, and confectionery.
- Enhances texture, shelf-life, and prevents phase separation in emulsified food systems.
Secondary Uses
- Pharmaceutical Industry:
- Acts as an emulsion stabilizer in topical ointments and creams.
- Used in drug delivery systems to enhance dispersion of active ingredients.
- Industrial Applications:
- Used in biodegradable lubricants and environmentally friendly surfactant systems.
- Suitable for formulations requiring low toxicity and high skin compatibility, such as baby care products or specialty cleaners.
