Description

Polyglyceryl-10 Tetradecanedioate is the ester of tetradecanedioic acid and Polyglyceryl-10. This compound is used in the cosmetic and personal care industries for its emulsifying, moisturizing, and skin-conditioning properties.

Chemical Composition and Structure

Polyglyceryl-10 Tetradecanedioate is composed of esters formed by the reaction of tetradecanedioic acid with Polyglyceryl-10. Polyglyceryl-10 is a polymer of glycerol with an average of 10 glycerol units. The esterification process links the carboxyl groups of tetradecanedioic acid with the hydroxyl groups of Polyglyceryl-10, creating a stable compound.

Physical Properties

Polyglyceryl-10 Tetradecanedioate typically appears as a clear to slightly yellow liquid or semi-solid, depending on the specific composition and processing methods used. It is soluble in water and organic solvents, and it has a mild, neutral aroma. The compound's structure allows it to act as an effective emulsifier and moisturizer, enhancing the texture and stability of cosmetic formulations.

Production Process

Synthesis of Polyglyceryl-10: Glycerol is polymerized to produce Polyglyceryl-10, a polymer containing an average of 10 glycerol units.
Preparation of Tetradecanedioic Acid: Tetradecanedioic acid is obtained from natural sources or synthesized through chemical processes.
Esterification: Polyglyceryl-10 is reacted with tetradecanedioic acid in the presence of a catalyst. The esterification process links the carboxyl groups of the acid with the hydroxyl groups of the polyglycerol.
Purification: The resulting ester is purified to remove any unreacted materials and by-products, ensuring a high-quality final product.
Quality Control: Rigorous quality tests are conducted to evaluate the purity, stability, and composition of the ester, including chemical and microbiological analyses.

Applications

Cosmetic Products: Used in creams, lotions, and emulsions for its emulsifying and moisturizing properties, enhancing the texture and stability of the formulations.
Skin Care: Ideal for products aimed at providing moisturizing and skin-conditioning benefits due to its ability to improve skin hydration and smoothness.
Personal Care Products: Used in body washes, soaps, and other personal care items for its emulsifying and conditioning effects, contributing to a pleasant skin feel.

Environmental and Safety Considerations

Polyglyceryl-10 Tetradecanedioate is generally considered safe for use in cosmetic and personal care products. It is non-irritating and suitable for all skin types. Proper use within recommended concentrations is essential to ensure safety and maximize effectiveness. Efforts to source raw materials sustainably and to use environmentally friendly production methods are important to mitigate any potential environmental impact.

INCI


Hair conditioning agent. A significant number of ingredients with specific and targeted purposes may co-exist in hair shampoo formulations: cleansers, conditioners, thickeners, matting agents, sequestering agents, fragrances, preservatives, special additives. However, the indispensable ingredients are the cleansers and conditioners as they are necessary and sufficient for hair cleansing and manageability. The others act as commercial and non-essential auxiliaries such as: appearance, fragrance, colouring, etc. Hair conditioning agents have the task of increasing shine, manageability and volume, and reducing static electricity, especially after treatments such as colouring, ironing, waving, drying and brushing. They are, in practice, dispersants that may contain cationic surfactants, thickeners, emollients, polymers. The typology of hair conditioning agents includes: intensive conditioners, instant conditioners, thickening conditioners, drying conditioners. They can perform their task generally accompanied by other different ingredients.

Humectant. Hygroscopic compound used to minimise water loss in the skin and to prevent it from drying out by facilitating faster and greater absorption of water into the stratum corneum of the epidermis. The epidermis is the most superficial of the three layers that make up human skin (epidermis, dermis and hypodermis) and is the layer that maintains hydration in all three layers. In turn, the epidermis is composed of five layers: horny, the most superficial, granular, spinous, shiny, and basal. Humectants have the ability to retain the water they attract from the air in the stratum corneum and have the function of moisturising the skin. They are best used before emollients, which are oil-based.
