Product Description

Versatile Solvent & Carrier for Fragrance and Cosmetic Formulations

Dipropylene Glycol (DPG) is a clear, low-odour liquid widely used as a solvent, carrier and diluent in fragrance, perfumery and personal-care formulations.

Its low odour makes it particularly useful for carrying fragrance compositions without significantly interfering with their intended aroma. DPG can be used in suitable perfume oils, fragrance blends, air-care formulations and cosmetic products, depending on the formulation requirements.

It is also valued for its good solvency, easy handling and compatibility with many fragrance and cosmetic ingredients.

Suitable for:
Perfume Oils • Fragrance Blends • Attars • Air-Care Formulations • Personal Care • Cosmetic Formulations • DIY Perfumery

For fragrance, cosmetic and DIY formulation use.

Safety Information

For fragrance, cosmetic and DIY formulation use only.

Do not ingest. Avoid direct contact with eyes. In case of eye contact, rinse thoroughly with clean water.

Avoid unnecessary prolonged contact with concentrated raw material. Use clean, dry equipment when handling.

Keep the container tightly closed when not in use and protect the contents from contamination and moisture.

Store in a cool, dry, well-ventilated place away from direct sunlight and excessive heat.

Keep out of reach of children.

When used in a finished cosmetic or fragrance product, the complete formulation should be assessed for its intended application and usage conditions.

FAQs

1. What is DPG?
DPG stands for Dipropylene Glycol, a liquid solvent and carrier used extensively in fragrance, cosmetic and personal-care formulations.

2. What is DPG mainly used for?
One of its most common applications is as a solvent and carrier for fragrances. It can also be used in suitable air-care and personal-care formulations.

3. Is DPG the same as Propylene Glycol (PG)?
No. DPG and PG are different materials. Both can function as solvents, but they have different physical properties and are selected according to the formulation.

4. Why is DPG commonly used in perfumery?
Its relatively low odour and good solvency make it useful for diluting and carrying fragrance materials without unnecessarily dominating the fragrance profile.

5. Can DPG be used to dilute fragrance oil?
Yes, provided the fragrance composition is compatible with DPG and the resulting product is suitable for its intended application.

6. Can DPG be used for making attar or perfume oil?
It is commonly used as a carrier/diluent in certain non-alcoholic fragrance formulations. The appropriate ratio depends on the fragrance concentrate and desired performance.

7. Can I make spray perfume using only fragrance and DPG?
DPG is not a direct substitute for ethanol in every spray-perfume formulation. High DPG levels can affect viscosity, spray characteristics, evaporation and fragrance diffusion. Formulate according to the intended delivery system.

8. Does DPG have a smell?
Good-quality DPG generally has very little characteristic odour, which is one reason it is useful in fragrance applications.

9. Is DPG water soluble?
Yes, DPG is miscible with water, although a complete fragrance formulation may still become cloudy or separate depending on the other ingredients present.

10. Is DPG a fragrance fixative?
I'd be careful with that claim. DPG's lower volatility can influence evaporation and fragrance delivery, but its primary role should be described as a solvent, carrier and diluent, rather than promising it will “fix” or dramatically increase fragrance longevity.

11. Can DPG be applied directly to skin?
We should not market the raw ingredient for direct application. It is better presented as a formulation ingredient used at an appropriate level in a properly designed finished product.

12. Can DPG be used in cosmetics?
Yes, appropriate grades of Dipropylene Glycol are used in cosmetic and personal-care formulations. Suitability depends on the particular grade and intended application.

13. Is DPG a preservative?
No. DPG should not be presented as a replacement for an appropriate preservative system.

14. How should DPG be stored?
Keep the container tightly closed in a cool, dry place protected from direct sunlight, excessive heat and contamination.
