Description
Di-p-methylbenzylidenesorbitol, also known as (2R)-Sorbitan monolauric acid ester (S677000), is a lipophilic nonionic surfactant. It is characterized by its ability to act as an emulsifying agent, which is crucial in the formation and stabilization of emulsions.
Used in Pharmaceutical Industry:
Di-p-methylbenzylidenesorbitol is used as an emulsifying agent for the preparation of emulsions, creams, and ointments. Its lipophilic nature allows it to effectively stabilize mixtures of oil and water, which is essential in the creation of various pharmaceutical formulations.
Used in Cosmetic Industry:
In the cosmetic industry, Di-p-methylbenzylidenesorbitol serves a similar purpose as in the pharmaceutical sector. It is used as an emulsifying agent in the preparation of creams and ointments, ensuring that the products have a consistent texture and remain stable over time. This contributes to the efficacy, safety, and aesthetic appeal of cosmetic products.
Check Digit Verification of cas no
The CAS Registry Mumber 81541-12-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,5,4 and 1 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 81541-12:
(7*8)+(6*1)+(5*5)+(4*4)+(3*1)+(2*1)+(1*2)=110
110 % 10 = 0
So 81541-12-0 is a valid CAS Registry Number.

Method of preparing powdery diacetal clarifying agent
-
Page/Page column 18, (2019/07/17)
Provided is a method of preparing a powdery diacetal clarifying agent, which comprises mixing an aromatic aldehyde, a polyol, and an acid catalyst in an organic polar solvent, adding a hydrogenating agent and an inorganic silicon-containing agent into the foregoing mixture, and filtering the mixture. The powdery diacetal clarifying agent prepared by the method can have excellent flowability, dispersability, thermal resistance, and color stability. Accordingly, the powdery diacetal clarifying agent does not release stinking odor and incur yellowing at high temperature, allowing the plastic articles to have improved appearance and visual appeal.
