Description

Macadamia seed oil polyglyceryl-6 esters behenate is a class of compounds derived from the esterification of behenic acid with the product obtained by the transesterification of macadamia seed oil and polyglycerin-6. these esters are valued for their emollient and stabilizing properties, making them useful in various cosmetic and pharmaceutical applications.

CHEMICAL COMPOSITION AND STRUCTURE

chemically, macadamia seed oil polyglyceryl-6 esters behenate consists of fatty acid chains from macadamia seed oil bonded to a polyglycerol backbone containing six glycerol units, further esterified with behenic acid. the resulting structure provides unique stability and functionality.

PHYSICAL PROPERTIES

Appearance: generally a clear to pale yellow liquid or semi-solid.
Odor: mild, characteristic odor.
Solubility: insoluble in water, but dispersible in oil and some organic solvents.
Density: varies based on specific formulation, generally around 0.9 g/cm³.
Melting Point: depends on the specific fatty acid composition and degree of esterification.

PRODUCTION PROCESS

Raw Material Preparation: macadamia seed oil is extracted from the seeds of Macadamia integrifolia.
Polyglycerol Preparation: glycerol is polymerized to form polyglyceryl-6.
Transesterification: macadamia seed oil is reacted with polyglyceryl-6 under controlled temperature and pressure conditions to produce the intermediate product.
Esterification with Behenic Acid: the intermediate product is further esterified with behenic acid to obtain the final compound.
Purification: the resulting esters are purified through distillation or other methods to remove any unreacted components and by-products.
Quality Control: the final product is tested for purity, consistency, and compliance with industry standards.

APPLICATIONS

Medical: used in topical formulations for its skin-conditioning and protective properties, aiding in the treatment of dry and sensitive skin conditions.
Cosmetics: commonly found in lotions, creams, lip balms, and hair care products as an emollient and stabilizer. enhances the texture, spreadability, and moisturizing effects of cosmetic products.
Others: used in the food industry as a non-toxic, biodegradable emulsifier and stabilizer in various formulations.

ENVIRONMENTAL AND SAFETY CONSIDERATIONS

Biodegradability: macadamia seed oil polyglyceryl-6 esters behenate are biodegradable, making them environmentally friendly.
Toxicity: generally considered non-toxic and safe for use in personal care products. however, it is essential to ensure that the product is free from contaminants and complies with regulatory standards.
Allergenicity: individuals with nut allergies should exercise caution, as macadamia seed oil is derived from macadamia seeds. patch testing is recommended for sensitive individuals.

INCI


Skin conditioning agent - Emollient. Emollients have the characteristic of enhancing the skin barrier through a source of exogenous lipids that adhere to the skin, improving barrier properties by filling gaps in intercorneocyte clusters to improve hydration while protecting against inflammation. In practice, they have the ability to create a barrier that prevents transepidermal water loss. Emollients are described as degreasing or refreshing additives that improve the lipid content of the upper layers of the skin by preventing degreasing and drying of the skin. The problem with emollients is that many have a strong lipophilic character and are identified as occlusive ingredients; they are oily and fatty materials that remain on the skin surface and reduce transepidermal water loss. In cosmetics, emollients and moisturisers are often considered synonymous with humectants and occlusives.

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.

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.
