Description:
Dipropylene Glycol (DPG) is a clear, colorless, low-odor liquid glycol used primarily as a solvent, carrier, humectant, and viscosity modifier. It has good compatibility with water, alcohols, fragrances, and many organic materials. DPG is commonly used in cosmetics, personal care products, fragrances, household products, and industrial formulations.
Typical usage rates
The appropriate level depends on the application and the desired function:
| Application | Typical usage rate |
|---|---|
| Fragrance / perfume | 5–50% |
| Cosmetics & personal care | 1–10% |
| Creams & lotions | 1–5% |
| Liquid soaps / body wash | 1–5% |
| Air fresheners | 5–30% |
| Industrial solvent applications | 5–50%+ |
| As a carrier/solvent for fragrances | 10–50% |
These are typical formulation ranges, not universal regulatory limits. The final rate should be determined by the specific product, grade of DPG, formulation requirements, and applicable regulations.
Benefits
-
Excellent solvent: Helps dissolve and incorporate fragrances, oils, and other ingredients.
-
Fragrance carrier: Helps distribute fragrance materials evenly and can contribute to controlled evaporation.
-
Humectant: Helps retain moisture in some cosmetic formulations.
-
Low odor: Useful when the base material should have minimal impact on the product's fragrance.
-
Good water compatibility: Can be incorporated into many water-based formulations.
-
Viscosity control: Can help adjust the texture and flow characteristics of formulations.
-
Improves formulation stability: Can assist with keeping certain ingredients uniformly dispersed or dissolved.
-
Versatile: Suitable for personal care, fragrance, household, and various industrial applications.
Important: DPG is available in different grades, such as fragrance grade, cosmetic grade, and industrial grade. For cosmetics or products applied to skin, use a grade appropriate for that application and follow the supplier's specification and safety data sheet.
If you tell me what product you are formulating (e.g., perfume, body lotion, shampoo, liquid soap, air freshener, or detergent), I can give you a more specific recommended DPG percentage and a sample formulation.
