Dipropylene Glycol (DPG) for Skin Application with Fragrance Oil

Dipropylene Glycol (DPG) is a widely used solvent for fragrance oils in cosmetic applications, including products intended for direct skin application like perfumes, body sprays, and roll-ons. It is generally considered safe for use on the skin when properly diluted in a finished product.

The usage rate of 1-100% you saw likely refers to its use as a solvent within a fragrance concentrate or as a component in a final formulation. Applying 100% DPG directly to the skin is not typically recommended as it could potentially cause dryness or mild irritation, although it is less harsh than some other solvents like pure ethanol.

When mixing fragrance oil with DPG for skin application, it's important to use an appropriate concentration for the final product (e.g., typically 10-20% fragrance oil in a solvent blend for perfumes, much lower for body sprays or lotions) to ensure safety and skin comfort.

Regarding the heating sensation compared to Propylene Glycol (PG): Propylene Glycol can sometimes cause a warming or tingling feeling on the skin, especially at higher concentrations. Dipropylene Glycol (DPG) is generally known to have a milder skin feel and is less likely to cause this heating sensation than Propylene Glycol. It is often chosen as a fragrance solvent partly because of its less irritating profile and smoother feel on the skin.
