Description

Disodium Polyglyceryl-3 Caprate/Caprylate Sulfosuccinate is a cosmetic ingredient commonly used as a surfactant and emulsifier. It is the disodium salt of a polyglyceryl-3 caprate/caprylate half ester of sulfosuccinic acid. This ingredient is especially favored in cosmetic formulations for its mildness, excellent skin compatibility, and its ability to form gentle and effective cleansing formulations.

Chemical Composition and Structure

This compound involves the esterification of polyglycerol-3 with capric and caprylic acids, followed by the sulfonation of the ester with sulfosuccinic acid. The final product is then neutralized to form the disodium salt. The structure provides significant surfactant properties, enhancing the product's ability to reduce surface tension, thus facilitating the removal of oils and dirt from the skin and hair.

Physical Properties

Disodium Polyglyceryl-3 Caprate/Caprylate Sulfosuccinate typically appears as a light amber to clear liquid at room temperature. It is highly soluble in water and has excellent foaming properties, which make it particularly useful in aqueous solutions and formulations.

Production Process

Synthesis: The synthesis involves esterification of polyglycerol-3 with a mixture of capric and caprylic acids. Subsequent sulfonation with sulfosuccinic acid introduces the sulfonate groups necessary for surfactant properties.
Neutralization: The acidic form of the sulfosuccinate ester is neutralized with sodium hydroxide to produce the disodium salt, enhancing its solubility and stability in water.
Purification: The synthesized product undergoes purification steps to ensure removal of unreacted materials and by-products.
Quality Control: Comprehensive testing, including pH, solubility, and performance assessments, ensures the product meets stringent cosmetic industry standards.

Applications

Cosmetic Products: Widely used in facial cleansers, shampoos, and body washes, where it serves as a gentle surfactant that effectively cleans without stripping natural oils.
Skin Care: Utilized in skincare formulations for sensitive skin due to its mild and non-irritating nature.
Baby Care Products: Ideal for baby shampoos and washes as it is extremely gentle on the skin and eyes.

Environmental and Safety Considerations

Disodium Polyglyceryl-3 Caprate/Caprylate Sulfosuccinate is recognized for its safety and mildness, making it suitable for sensitive skin formulations. It is biodegradable, reflecting an environmentally friendly profile. As always, it is important to follow recommended usage levels to ensure safety and effectiveness in cosmetic products.

INCI


Cleansing agent. Ingredient that cleanses skin without exploiting the surface-active properties that produce a lowering of the surface tension of the stratum corneum.

Surfactant - Foam booster. It has the effect of introducing gas bubbles into the water and affects the cleaning process by helping to spread the cleanser. Since sebum has an inhibiting effect on the bubble, more foam is produced in the second shampoo.

Surfactant - Cleansing agent. Cosmetic products used to cleanse the skin utilise the surface-active action that produces a lowering of the surface tension of the stratum corneum, facilitating the removal of dirt and impurities.
