Fragrance and essence grade dipropylene glycol (DPG), CAS No. 110-98-5, is a high purity, low odor organic compound with excellent solvent compatibility and chemical stability. The hydroxyl and ether bonds in its molecular structure endow it with excellent moisture retention and solubility, making it an ideal carrier solvent in the fields of essence, cosmetics, food and beverage. This product undergoes strict purification processes and meets the standards for food additives (such as FDA certification) and cosmetic raw materials. It is widely used in fine chemical scenarios that require high safety and low odor.
Solvent and carrier action of essence flavor grade dipropylene glycol (DPG, CAS: 110-98-5) in perfume and essence formulations
As the gold solvent in the essence and fragrance industry, DPG can effectively dissolve natural essential oils, synthetic fragrances and aromatic compounds, ensure that the aroma components are evenly dispersed and extend the fragrance retention time. For example, in perfume formulations, DPG often uses more than 50% as the basic solvent to help stabilize the hierarchical structure of complex fragrance. Its low volatility and high boiling point characteristics (235 ° C) make it particularly suitable for products that require slow release of aroma, such as candles and aroma diffusers. By adjusting the ratio of DPG to fragrance (such as 15-25%), the speed and persistence of aroma diffusion can be optimized. In addition, DPG serves as a carrier in UV curable inks and aromatherapy products, which can enhance the stability and skin penetration of essential oils.
Multifunctional application of essence flavor grade dipropylene glycol (DPG, CAS: 110-98-5) in cosmetics and personal care products
In the field of cosmetics, DPG has become a key ingredient in skincare, hair care, and makeup products due to its low irritation and high compatibility
Skin care products: As a humectant and coupling agent, DPG can enhance the texture uniformity of lotion and face cream, and improve the skin absorption effect of active ingredients (such as hyaluronic acid). For example, in sunscreen, DPG helps disperse sunscreen particles and enhance skin feel.
Hair care products: used for shampoo, hair dye and styling spray. DPG can adjust the product viscosity and prevent separation of ingredients, while reducing irritation to the scalp.
Color makeup: In lipstick, eye shadow and foundation make-up, DPG is used as a plasticizer to enhance the ductility and adhesion of the formula, and as a solvent to dissolve pigments and pearlescent.
The role of flavor carrier of essence flavor grade dipropylene glycol (DPG, CAS: 110-98-5) in food, beverage and oral care
As a food grade solvent, DPG complies with FDA 21 CFR § 172.856 standards and can be safely used for dilution and stabilization of food flavorings and seasonings. For example:
Beverage industry: In carbonated drinks, fruit juices and alcoholic drinks, DPG helps to dissolve oil soluble essence (such as citrus essential oils), ensure uniform distribution of flavor and prevent sedimentation.
Baking and candy: used for essence capsules and slow release spices. DPG improves the taste level of products by controlling the speed of aroma release.
Oral care: In toothpaste and mouthwash formulations, DPG acts as a solvent to enhance the diffusion of cooling ingredients such as menthol, while regulating the moisturizing and flowability of the product.
Low odor solution of essence flavor grade dipropylene glycol (DPG, CAS: 110-98-5) in aromatherapy and household fragrance
The almost odorless nature of DPG makes it an ideal choice for aromatherapy and home fragrance products:
Aroma diffuser: After mixing with essential oils, DPG slowly evaporates to release aroma, commonly used in rattan aromatherapy and ultrasonic aromatherapy machines.
Candle and aromatherapy wax: As a spice carrier, DPG can improve the absorption capacity of wax base to essence, and reduce smoke and odor during combustion.
Air freshener: In spray type products, DPG helps to disperse essence and extend the fragrance retention time, while serving as a coupling agent to improve the water oil compatibility.
Extended application of essence flavor grade dipropylene glycol (DPG, CAS: 110-98-5) in industry and special fields
In addition to the above scenarios, DPG also demonstrates unique value in the following areas:
Pharmaceutical industry: As a drug carrier, DPG is used for topical creams and transdermal patches to enhance the skin permeability of active ingredients.
Environmentally friendly coatings: As a low VOC solvent, DPG can replace traditional aromatic solvents for water-based wood coatings and environmentally friendly inks, meeting the requirements of the EU REACH regulation.
Electronic chemicals: High purity DPG is used for cleaning precision electronic components, and its low residue characteristics can prevent corrosion of circuit boards.
