Diglycerin is a multifunctional cosmetic ingredient used primarily for its humectant, moisturizing, skin-conditioning and solvent properties. Also known as Diglycerol, it is a glycerol-derived ingredient containing multiple hydroxyl groups that contribute to its strong affinity for water.
Diglycerin is used in skincare, haircare and personal-care formulations where moisture retention, skin feel and formulation support are important. It can be incorporated into moisturizers, serums, lotions, cleansers, gels and other cosmetic formulations.
Diglycerin has the molecular formula C₆H₁₄O₅ and molecular weight 166.17 g/mol. Depending on the reference and material identity, CAS numbers associated with Diglycerin/Diglycerol include 59113-36-9 and 627-82-7.
Diglycerin, also called Diglycerol, is a glycerol-derived polyol containing multiple hydroxyl groups. Its high affinity for water makes it particularly useful as a humectant in cosmetic and personal-care formulations.
Unlike conventional glycerin, Diglycerin has a larger molecular structure containing two glycerol-derived units connected through an ether linkage. This structural difference gives it different physical and formulation characteristics while retaining strong water-attracting properties.
In cosmetic formulations, Diglycerin is mainly used to support hydration and moisture management. It can also function as a solvent and contribute to formulation texture and stability. Cosmetic ingredient references identify Diglycerin as a humectant and solvent.

PubChem identifies Diglycerol/Diglycerin with formula C₆H₁₄O₅ and molecular weight 166.17 g/mol, while cosmetic references list Diglycerin as a humectant and solvent.
Diglycerin is primarily valued as a humectant. It helps attract and retain moisture, making it useful in formulations designed to improve skin hydration.
Its multiple hydroxyl groups contribute to its water affinity and make it suitable for moisturizing formulations.
Diglycerin can contribute to the moisturizing performance of skincare products by supporting moisture retention at the skin surface.
It is suitable for formulations where a smooth, hydrated and comfortable skin feel is desired.
Diglycerin can contribute to skin-conditioning properties and help improve the sensory characteristics of cosmetic formulations.
It is particularly relevant to moisturizers, serums, lotions and other products intended for regular skin application.
Diglycerin can function as a solvent and formulation aid. Its water compatibility allows it to support the incorporation and distribution of selected water-compatible ingredients.
Diglycerin is a viscous liquid and can influence the texture and rheology of a finished formulation. The effect depends on concentration and the complete formulation system.
Diglycerin may contribute to formulation stability and ingredient distribution in suitable cosmetic systems. Its use should be evaluated together with the complete formulation, emulsifier system and other functional ingredients.
Diglycerin can be used in a broad range of cosmetic and personal-care products, including:
Cosmetic ingredient references specifically describe applications in moisturizers, lotions, serums, cleansers, body washes and makeup formulations.
Diglycerin is particularly useful in skincare formulations focused on hydration and moisture retention.
It can be incorporated into serums, creams, lotions, gels and cleansing products where formulators want a multifunctional water-compatible ingredient.
Its humectant properties can support formulations intended to provide a hydrated and comfortable skin feel.
Diglycerin can also be used in hair-care formulations where moisture management and conditioning are important.
It can be incorporated into conditioners, hair masks, leave-in products and other formulations designed to improve the moisture profile and sensory properties of the hair-care system.
Diglycerin can be used in cleansers and body washes to help support skin hydration during and after cleansing.
Its humectant functionality can be useful in formulations designed to provide a less drying sensory experience.
When using Diglycerin in cosmetic formulations, manufacturers should evaluate:
Diglycerin should be selected according to the intended cosmetic application and the technical specification of the supplied grade.
