Dipropylene Glycol (DPG)

Description:
Dipropylene glycol (DPG) is a clear, colorless liquid that serves as a versatile ingredient in skincare formulations as well as fragrance and perfume applications. It is a type of glycol compound that is widely used as a solvent, humectant, and carrier agent. DPG has excellent solubility in water and many other organic solvents, making it suitable for a wide range of skincare and fragrance applications. It helps to improve the texture, stability, and performance of skincare products while also contributing to the scent and longevity of fragrances.

Benefits:

• Solvent properties: DPG acts as a solvent, helping to dissolve and disperse other ingredients in skincare formulations, fragrances, and perfumes.
• Humectant: It attracts moisture from the environment and helps to retain it in the skin, promoting hydration and preventing dryness.
• Carrier agent: DPG can effectively carry active ingredients into the skin, enhancing their absorption and efficacy in skincare products, while also carrying fragrance molecules in perfumes.
• Texture improvement: It contributes to the smoothness and spreadability of skincare products, improving their overall texture.
• Stability enhancer: DPG helps to stabilize formulations, preventing ingredient separation and maintaining product integrity in skincare and fragrance applications.
• Moisturizing benefits: It provides moisturizing properties, leaving the skin feeling hydrated and soft in skincare products, while also enhancing the longevity and diffusion of fragrances.

Usage: 
Dipropylene glycol (DPG) is commonly used in skincare products, fragrance formulations, and perfumes as a solvent, humectant, and carrier agent.

Fragrance Fixative:

Dipropylene glycol (DPG) possesses valuable fragrance fixative properties that can significantly enhance the longevity of scents. While DPG is widely recognized for its role as a versatile solvent, humectant, and carrier agent, it also demonstrates the ability to slow down the evaporation rate of fragrance molecules. This unique characteristic contributes to a prolonged scent experience on the skin or in the surrounding environment.

In fragrance formulations, DPG can be utilized effectively at concentrations up to 26.7%, allowing perfumers to leverage its exceptional fixative properties while considering the overall composition and desired scent characteristics. However, to maintain the desired balance and avoid potential alterations to the fragrance formulation, it is generally recommended to use DPG at concentrations below 10%.

When incorporating DPG as a fragrance fixative in cream and lotion formulations, it is advisable to consider the specific scent strength and product characteristics. For fragrances with heavy or potent aromas, using DPG closer to the maximum recommended percentage ensures proper fixation. On the other hand, for fragrances with lighter scents, it is recommended to use DPG at lower concentrations, preferably below 10%, to prevent the fixative scent from overpowering the desired fragrance notes.

To achieve a harmonious and well-rounded scent profile in cream and lotion formulations, it is essential to find the optimal balance between the fixative properties of DPG and the desired fragrance. Conducting small-scale tests and adjusting the percentage of DPG accordingly will allow for fine-tuning the aroma strength and overall sensory experience.

Applications:

• Skincare products: Moisturizers, serums, lotions, creams, toners, masks, body washes, shampoos, hair conditioners.
• Fragrances and perfumes: Eau de parfum, eau de toilette, cologne, body mists, perfumed oils.
