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.

Amphoteric Surfactants
Amphoteric surfactants are unique surface-active agents that can act as either anionic or cationic surfactants depending on the pH of the solution. These molecules contain both acidic (carboxyl or sulfonic) and basic (amine or quaternary ammonium) functional groups, giving them high versatility, mildness, and compatibility with other surfactants. Amphoteric surfactants are widely used in personal care, household cleaning, industrial applications, pharmaceuticals, and specialty formulations where low irritation and effective cleansing are critical. Common examples include Cocamidopropyl Betaine and Lauryl Betaine.
Cocamino Propyl Betaine Desmocol
Cocamino Propyl Betaine Desmocol is a mild amphoteric surfactant derived from coconut oil fatty acids and amino acids. It appears as a clear to slightly hazy liquid with a faint coconut-like odor. CAPB is widely used in personal care and household cleaning products for its excellent foaming, cleansing, and conditioning properties. Being a zwitterionic surfactant, it is compatible with anionic, cationic, and nonionic surfactants, enhancing the mildness and stability of formulations. The 30% active solution is easy to handle and incorporate in various cosmetic and detergent products. It functions as a foam booster, viscosity builder, and anti-irritant agent, making it a versatile ingredient in mild formulations.
Emulsifying Wax Anionic
Emulsifying Wax Anionic is a versatile surfactant blend composed primarily of fatty alcohols (such as cetyl or stearyl alcohol) and anionic surfactants like sodium lauryl sulfate. It is designed to stabilize oil-in-water (O/W) emulsions by reducing interfacial tension between water and oil phases. It appears as white to off-white solid flakes or pellets, with a mild fatty odor and is dispersible in water with agitation and mild heat. Known for its excellent emulsification, cleansing, and thickening properties, this emulsifying wax is widely used in cosmetics, pharmaceuticals, household cleaners, and industrial applications.

This polymer is typically supplied as a clear to slightly hazy viscous liquid or gel. It is compatible with a broad range of surfactants and ingredients, enhancing the sensory profile of shampoos, conditioners, styling products, and skincare formulations. Galsilk 700 is also valued for its film-forming properties and ability to improve product stability.
Glycerol Monostearate Flakes
Glycerol Monostearate Flakes is a white to off-white waxy flake form emulsifier composed of 40% monoglycerides of fatty acids, primarily stearic and palmitic acids, combined with other glycerides and esters. Derived mainly from vegetable oils, this food-grade emulsifier is widely utilized in food, cosmetic, pharmaceutical, and industrial sectors for its multifunctional properties. GMS 40% flakes serve as effective emulsifiers, stabilizers, anti-caking agents, and texture enhancers, with excellent compatibility and versatility in formulations requiring semi-solid or solid fats.
Myristic Acid
Myristic Acid is a saturated fatty acid with a 14-carbon chain, naturally found in nutmeg, coconut oil, palm kernel oil, and butter fat. It appears as a white crystalline solid with a faint odor. It is widely used in the manufacture of soaps, cosmetics, surfactants, and food additives due to its emollient and cleansing properties. Myristic Acid acts as a key intermediate in the production of esters, detergents, and lubricants.
