Functions in Cosmetics:

Humectant: Helps to attract and retain moisture in the skin, keeping it hydrated.

Preservative: Exhibits antimicrobial properties, helping to extend the shelf life of products by preventing the growth of bacteria, yeast, and mold.

Solvent: Acts as a solvent for other ingredients, improving the stability and texture of formulations.

Emollient: Contributes to the softening and smoothing of the skin.

Viscosity Control: Helps to adjust the thickness and consistency of cosmetic products.

Benefits:

Gentle on Skin: Often used in products designed for sensitive skin due to its mild nature.

Non-Irritating: Generally considered safe and non-irritating, making it suitable for a wide range of skin types.

Regulatory Approval: Decylene glycol is approved for use in cosmetics by regulatory bodies such as the European Union (EU) and the United States (FDA).

Concentration: Typically used at low concentrations (usually less than 1%) in formulations.

Product characteristics: solid powder

Solubility: Soluble in ethanol, glycols (eg propylene glycol, butylene glycol). Less soluble in water

Storage: can be stored at room temperature But close the lid of the bottle tightly. and protected from sunlight or heat, the product has a shelf life of at least 2 years
