When it comes to creating professional-quality room and linen sprays, achieving a formula that stays clear, stable and beautifully blended can be a challenge. Fragrance oils and essential oils naturally resist mixing with water — that’s where DPG (Dipropylene Glycol) steps in.
Used widely across fragrance and cosmetic applications, DPG acts as a co-solvent and fragrance carrier, helping oils disperse evenly through your base and preventing that unwanted layer of separation.
What Is DPG?
Dipropylene Glycol is a clear, low-odour liquid derived from propylene oxide. In formulation, it works as a co-solvent, meaning it enhances the solubility of oils in bases that contain water or alcohol — without acting as a surfactant.
DPG is known for its stability, versatility, and ability to carry fragrance evenly. It evaporates slowly, extending the scent experience while keeping your blend visually clear and consistent.
How DPG Enhances Solubility in Your Base
Because oil and water naturally repel each other, sprays without the right blending agent can become cloudy or separate. DPG acts as a bridge — helping oils disperse more readily into your base.
However, it’s worth noting that DPG is a co-solvent, not a true solubiliser. While it dramatically improves clarity and stability, highly water-based systems or heavy fragrance loads may still need a primary solubiliser such as Polysorbate 20 or ethoxylated castor oil to achieve complete clarity.
Together, DPG and a surfactant-based solubiliser form a reliable duo that keeps your room and linen sprays clear, smooth, and beautifully balanced.
Why Makers Love DPG
-
Versatile: Works with both essential oils and fragrance oils across water, alcohol or hybrid bases.
-
Stable: Helps reduce separation and supports even blending.
-
Gentle: Low-odour, non-sensitising, and widely accepted under cosmetic and fragrance safety guidelines.
-
Reliable: Delivers consistent results in small-batch or large-scale production.
Tips for Using DPG in Your Room or Linen Sprays
-
Always pre-blend DPG with your fragrance oil before adding it to the base for the smoothest result.
-
If using a high-water base or heavy fragrance percentage, consider pairing DPG with a mild solubiliser, like Polysorbate 20, for complete clarity.
-
Stir gently and allow time for the blend to settle before bottling.
For Makers Who Value Clarity and Consistency
Whether you’re crafting a bespoke linen spray or refining a large-scale formulation, DPG is a trusted co-solvent that brings clarity, consistency and polish to your final product. It ensures your scent stays true, your formula stays stable, and your spray looks as luxurious as it smells.
