Description
Dipropylene glycol, a mixture of isomers, is a colorless, odorless, slightly viscous liquid with low vapor pressure and miscibility with water. It is known for its various applications across different industries due to its unique properties.
Uses
Used in Cosmetics Industry:
Dipropylene glycol is used as a solvent, plasticizer, and polymerization initiator and monomer for its ability to mask odors, add fragrance, decrease product viscosity, and act as a carrier for essential oils and fragrance oils.
Used in Entertainment Industry:
Dipropylene glycol is used as an active ingredient in commercial fog fluid, providing a safe and effective means for creating fog effects in fog machines for various entertainment purposes.
Used in Chemical Industry:
Dipropylene glycol serves as an intermediate in the production of polyurethane polyols, alkyd resins, and non-reinforced polyesters, contributing to the development of various chemical products.
Used in Dyes and Paints Industry:
It is utilized as a solvent and additive in the manufacturing of dyes and paints, enhancing their performance and quality.
Used in Automotive Industry:
Dipropylene glycol is used in hydraulic brake fluids, ensuring efficient and safe braking systems in vehicles.
Used in Manufacturing Industry:
It is employed as a component in cutting oils, improving the performance and longevity of cutting tools and machinery.
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.
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.
