Dipropylene Glycol is a multifunctional cosmetic and personal-care ingredient widely used as a solvent, fragrance carrier, viscosity-controlling and formulation-support ingredient. It is commonly abbreviated as DPG and is used in skincare, haircare, fragrance, cleansing and other cosmetic formulations.
Commercial Dipropylene Glycol is generally supplied as a mixture of related propylene glycol ether isomers. The commonly used CAS Number for the mixture is 25265-71-8, with molecular formula C₆H₁₄O₃ and molecular weight of approximately 134.17 g/mol.
Dipropylene Glycol is generally a clear, colorless to slightly colored liquid with good compatibility with water and many organic materials. Its solvent properties make it particularly useful for dissolving or carrying fragrances, essential oils and selected cosmetic ingredients.
In cosmetic formulations, Dipropylene Glycol can also help modify viscosity and support the uniform incorporation of functional ingredients. It is used across a wide range of products including perfumes, fragrances, skincare products, haircare products, deodorants, makeup and bath and shower formulations.
Dipropylene Glycol is a propylene glycol ether-type diol formed through the linkage of propylene glycol units. Unlike simple glycols such as Propylene Glycol, commercial Dipropylene Glycol is commonly supplied as an isomeric mixture.
It is commonly identified by the abbreviation DPG and CAS Number 25265-71-8.
Dipropylene Glycol is valued in cosmetic formulation because it combines useful solvent characteristics with fragrance compatibility and viscosity-control properties. Cosmetic ingredient references identify its principal functions as solvent, viscosity controlling, masking and perfuming.

Dipropylene Glycol is primarily valued as a solvent in cosmetic and personal-care formulations. It can help dissolve and incorporate compatible ingredients into finished products.
Its solvent properties make it particularly useful when formulators need to incorporate fragrance materials, essential oils or other functional ingredients.
DPG is widely used in fragrance systems as a carrier and solvent for fragrance materials. It can help distribute fragrance components uniformly within a formulation.
It is used in perfumes, fragrance preparations and selected personal-care products.
Dipropylene Glycol can contribute to the viscosity and flow characteristics of cosmetic formulations. This makes it useful when formulators need to adjust the physical properties of a liquid system.
DPG can support the formulation and delivery of perfuming materials and is recognized in cosmetic ingredient references for perfuming-related functionality.
As a multifunctional solvent, Dipropylene Glycol can assist with the incorporation and distribution of selected cosmetic ingredients and contribute to formulation uniformity.
Dipropylene Glycol is particularly relevant to:
Its solvent and carrier properties support the incorporation and distribution of fragrance materials.
Potential applications include:
Dipropylene Glycol can be considered for:
DPG can be used in selected:
Potential applications include:
Dipropylene Glycol has been reported in skincare, haircare, deodorant, makeup and bath/shower applications.
Dipropylene Glycol is generally handled as a liquid cosmetic ingredient and is suitable for many water-containing and mixed-solvent formulations.
Its concentration should be selected according to the intended function, product type, ingredient compatibility and applicable cosmetic requirements.
Formulators should evaluate compatibility with:
Commercial Dipropylene Glycol can contain different proportions of structural isomers. Therefore, the current product specification, COA and TDS should be used when defining the exact material supplied.
DPG should also be distinguished from Propylene Glycol. Propylene Glycol is a smaller diol with formula C₃H₈O₂, whereas Dipropylene Glycol is a higher molecular-weight glycol ether material.
Swapnroop provides Dipropylene Glycol (DPG) for customers seeking a cosmetic ingredient manufacturer and bulk supplier in India.
Dipropylene Glycol can be considered for fragrance, skincare, haircare, cleansing, deodorant, makeup and personal-care formulations requiring a multifunctional solvent and formulation-support ingredient.
For commercial procurement, customers should confirm the required grade, isomer profile where applicable, specification, packaging, quantity and current technical documentation before purchase.
The applicable batch COA and TDS should remain the controlling quality documents for the supplied material.
