Description
Propylene Glycol Monostearate (PGMS) is a mixture of propylene glycol monoand diesters of stearic and palmitic acids, characterized by its bland odor and taste. It is not a single chemical entity but a blend of esters derived from these fatty acids. For a comprehensive understanding of its properties, one can refer to the work of Burdock (1997).
Uses
Used in the Cosmetics Industry:
Propylene Glycol Monostearate is used as an emulsifier for the stabilization of oil and water mixtures in various cosmetic products. Its ability to create a uniform blend of these two immiscible substances allows for the creation of stable and consistent formulations, enhancing the texture, appearance, and performance of the final product.
Used in the Pharmaceutical Industry:
In the pharmaceutical sector, Propylene Glycol Monostearate serves as a solubilizer, enabling the incorporation of water-insoluble drugs into formulations. This improves the bioavailability and absorption of the active pharmaceutical ingredients, leading to more effective drug delivery systems.
Used in the Food Industry:
Propylene Glycol Monostearate is used as a stabilizer and emulsifier in the food industry, particularly in the production of baked goods, confections, and other processed foods. It helps maintain the desired texture, consistency, and shelf life of these products by preventing separation and improving the overall quality.
Used in the Personal Care Industry:
In personal care products, such as lotions, creams, and shampoos, Propylene Glycol Monostearate is used as a consistency agent and emollient. It helps to provide a smooth, creamy texture and enhances the skin's softness and suppleness, making it a valuable ingredient in various personal care formulations.
Used in the Plastics and Coatings Industry:
Propylene Glycol Monostearate is utilized as a plasticizer and lubricant in the plastics and coatings industry. It improves the flexibility, workability, and processability of various materials, contributing to the overall performance and durability of the final product.
Preparation
Produced commercially by catalytic transesterification between propylene glycol and a hydrogenated vegetable oil such
as soybean oil.
Check Digit Verification of cas no
The CAS Registry Mumber 142-75-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,4 and 2 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 142-75:
(5*1)+(4*4)+(3*2)+(2*7)+(1*5)=46
46 % 10 = 6
So 142-75-6 is a valid CAS Registry Number.

Encapsulation of microparticles in teardrop shaped polymer capsules of cellular size
-
, (2008/06/13)
Microparticles such as propagules of eukaryotic biocontrol agents are encapsulated in cellular-scale polymer capsules that have a diameter similar to normal eukaryotic cells in a range of about 10 μm to about 400 μm. The microparticles are encapsulated by adding a hydrophobic dispersion medium such as a mixture of chloroform and hexane or a mixture of corn oil and n-hexadecane having a specific gravity of about 1 and containing an emulsifier such as lecithin to an aqueous suspension of the microparticles and a polymer matrix precursor such as alginate, agitating vigorously to form a stable emulsion of microscopic globules containing a microparticle, and adding the emulsion to an aqueous solution containing a polymerizing agent such as calcium chloride to polymerize and precipitate the globules to form microparticles encapsulated in polymer matrix capsules that may be of a teardrop shape having a length of 40-200% longer than the diameter. Precipitation of the globules is regulated by substantially matching the Specific Gravity of the hydrophobic dispersion medium and the aqueous suspension. The microparticle may be a viable propagule of a weed pathogenic fungus to provide a herbicidal composition.
