1 -Oxydi-2-Propanol Cas 110-98-5

Bis(2-hydroxypropyl) Ether is commonly used as a plasticizer, an intermediate in industrial chemical reactions.

Properties: Dipropylene glycol is a kind of high purity product, suitable for flavor, cosmetics and other applications sensitive to odor. It is an odorless, colorless, water-soluble and hygroscopic liquid. Dipropylene glycol has a low vapor pressure and a moderate viscosity.

Application

Used in the manufacture of polyester resin. It is used as the solvent of cellulose acetate, cellulose nitrate, shellac varnish, castor oil, the component of fiber lubricant, and the preparation of plasticizer, fumigant, synthetic detergent, etc. In addition, dipropylene glycol can be used alone or in combination with diethylene glycol to extract aromatic hydrocarbons from hydrocarbons.

(1) Chemical synthesis: Dipropylene glycol is often used to synthesize other chemicals, such as polyethers, polyesters, etc.

(2) Solvent: Since dipropylene glycol has good water solubility, it can be used as a solvent to dissolve or dilute other substances.

(3) Spices and condiments: Dipropylene glycol can be used as a food additive to increase the taste and flavor of food.

(4) Cosmetics: Dipropylene glycol can be used as a moisturizer in cosmetics to improve the moisturizing effect of cosmetics.

(5) Pharmaceuticals: Dipropylene glycol can be used in the pharmaceutical field as a carrier or auxiliary for drugs.

Usage
1) Dipropylene glycol is the most ideal solvent for many fragrance and cosmetic applications. This raw material has good water, oil and hydrocarbon co-solubility and mild odor, little skin irritation, low toxicity, uniform distribution of isomers, excellent quality.

2) Dipropylene glycol can also be used as a coupling agent and moisturizer in a variety of different beauty cosmetic applications. In the field of perfume, the proportion of dipropylene glycol is more than 50%; In some other applications, the proportion of dipropylene glycol is generally less than 10% (by weight). Some of the specific product application areas include: curling lotions, skin cleans (cold creams, body washes, body washes, and skin lotions) deodorants, face, hand, and body skin care products, moisturizing skin care products, and lip balms, among others.

3) Dipropylene glycol can also play a role in unsaturated resins and saturated resins. It produces resins with superior softness. Crack resistance and weather resistance. The long-term yellowing resistance of the product is the value.

The primary use of Ammonium Sulphate is as a fertilizer for alkaline soils. In the soil the ammonium ion is released and forms a small amount of acid, lowering the pH balance of the soil, while contributing essential nitrogen for plant growth. The main disadvantage to the use of Ammonium Sulphate is its low nitrogen content relative to Ammonium Nitrate, which elevates transportation costs.
It is also used as an agricultural spray adjuvant for water soluble insecticides, herbicides, and fungicides. There it functions to bind iron and calcium cations that are present in both well water and plant cells. It is particularly effective as an adjuvant for 2,4-D (amine), glyphosate and glufosinate herbicides.
