25265-71-8 Usage
Chemical Properties
Dipropylene glycol is a colorless, odorless, slightly viscous liquid. it has a low vapor pressure, and is miscible with water.
Uses
Different sources of media describe the Uses of 25265-71-8 differently. You can refer to the following data:
1. Dipropylene glycol, mixture of isomers is used as a solvent, plasticizer, polymerization initiator and monomer. It acts as an additive used in perfumes, skin and hair care products. It is an active ingredient in commercial fog fluid, which is used as an entertainment in fog machines. Further, it is used as an intermediate in polyurethane polyols, alkyd resins and non-reinforced polyesters. In addition to this, it is used in dyes, paints, hydraulic brake fluids and cutting oils.
2. dipropylene glycol may be incorporated into a cosmetic for a variety of purposes including to mask odors or to perfume a product. In addition, it can help decrease product viscosity and serves as a solvent for essential oils and fragrance oils.
Production Methods
Dipropylene glycol is prepared commercially as a by-product
of propylene glycol production. Three linear isomers are
possible, but these have not been separated and studied, and
the exact composition of the commercial product is not
known. It is also possible to prepare cyclic isomers such
as 2,6-dimethyl-1,4-dioxane and 2,5-dimethyl-1,4-dioxane,
but these are not likely to form under conditions employed
commercially.
General Description
Thick odorless, colorless liquid. Sinks and mixes with water.
Air & Water Reactions
Dipropylene glycol is hygroscopic. Water soluble.
Reactivity Profile
Dipropylene glycol can react vigorously with acids and oxidizing materials. Dipropylene glycol is incompatible with strong bases. Dipropylene glycol is incompatible with peroxides.
Health Hazard
Minor eye irritation
Fire Hazard
Dipropylene glycol is combustible.
Flammability and Explosibility
Nonflammable
Chemical Reactivity
Reactivity with Water No reaction; Reactivity with Common Materials: No reaction; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.
Toxicology
Dipropylene glycol is not acutely toxic by oral, dermal, or inhalation exposure. Acute oral toxicity has been examined in the rat, mouse, and guinea pig and the reported LD50s were 15.8 ml/kg (16000 mg/kg), >2000 mg/kg and 17600 mg/kg, respectively.
Carcinogenicity
Dipropylene glycol has not been tested specifically for carcinogenicity; however, based on the results of a cancer bioassay of propylene glycol (to which dipropylene glycol is rapidly converted), dipropylene glycol is not expected to have carcinogenic potential.
Check Digit Verification of cas no
The CAS Registry Mumber 25265-71-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,2,6 and 5 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 25265-71:
(7*2)+(6*5)+(5*2)+(4*6)+(3*5)+(2*7)+(1*1)=108
108 % 10 = 8
So 25265-71-8 is a valid CAS Registry Number.
