Sclerocarya Birrea Seed Oil Polyglyceryl-10 Esters is a compound derived from the transesterification of Sclerocarya Birrea seed oil (commonly known as marula oil) with Polyglyceryl-10. This ingredient combines the emollient and nutrient-rich properties of marula seed oil with the moisturizing and emulsifying capabilities of Polyglyceryl-10, making it beneficial for use in various cosmetic and personal care products.

Chemical Composition and Structure

Sclerocarya Birrea Seed Oil Polyglyceryl-10 Esters consists of:

Sclerocarya Birrea Seed Oil: Rich in essential fatty acids (oleic acid, linoleic acid, and palmitic acid), vitamins (particularly vitamin E), phytosterols, and polyphenols.
Polyglyceryl-10: A polymer of glycerin with ten glycerol units, known for its excellent moisturizing and emulsifying properties.
Physical Properties

Sclerocarya Birrea Seed Oil Polyglyceryl-10 Esters is typically a light to dark yellow liquid with a mild, neutral aroma. It is both water-dispersible and oil-soluble, making it a versatile ingredient in emulsions and various cosmetic formulations.

Production Process

Extraction of Sclerocarya Birrea Seed Oil: Seeds are collected from mature Sclerocarya Birrea trees, cleaned, dried, and cold-pressed or solvent-extracted to obtain the oil.
Transesterification: The fatty acids from Sclerocarya Birrea seed oil are reacted with Polyglyceryl-10 under controlled conditions to form the ester compound.
Purification: The resulting product is purified to remove any unreacted materials or impurities.
Quality Control: Rigorous quality tests are conducted to evaluate the purity, stability, and composition of the final product, including chemical and microbiological analyses.

Applications

Cosmetic Products: Used in creams, lotions, serums, and emulsions for its emulsifying, moisturizing, and nourishing properties.
Skin Care: Ideal for formulations aimed at hydrating, protecting, and revitalizing the skin due to its combined benefits of marula seed oil and Polyglyceryl-10.
Hair Care: Incorporated into shampoos, conditioners, and treatments for its ability to nourish and strengthen hair while improving product texture and spreadability.
Personal Care Products: Used in body washes, soaps, and other personal care items for its emulsifying and hydrating effects.

Environmental and Safety Considerations

Sclerocarya Birrea Seed Oil Polyglyceryl-10 Esters is generally considered safe for use in cosmetic and personal care products. It is non-toxic and non-irritating to the skin. Sustainable harvesting practices for Sclerocarya Birrea are important to ensure the continued availability of its seeds and to protect the biodiversity of the regions where it is grown.

INCI


Surfactant - Emulsifying agent. Emulsions are thermodynamically unstable and are used to soothe or soften the skin and emulsify, so they need a specific, stabilising ingredient. This ingredient forms a film, lowers the surface tension and makes two immiscible liquids miscible. A very important factor affecting the stability of the emulsion is the amount of the emulsifying agent. Emulsifiers have the property of reducing the oil/water or water/oil interfacial tension, improving the stability of the emulsion and also directly influencing the stability, sensory properties and surface tension of sunscreens by modulating the filmometric performance.

Skin conditioning agent. It is the mainstay of topical skin treatment as it has the function of restoring, increasing or improving skin tolerance to external factors, including melanocyte tolerance. The most important function of the conditioning agent is to prevent skin dehydration, but the subject is rather complex and involves emollients and humectants that can be added in the formulation.
