9004-95-9 Usage
Description
Polyethylene Glycol Monocetyl Ether(Cetomacrogol 1000) is off-white waxy solid. Polyethylene Glycol Monocetyl Ether is the tradename for polyethylene glycol hexadecyl ether , which is nonionic surfactant produced by the ethoxylation of cetyl alcohol to give a material with the general formula HO(C2H4O)nC16H33. Several grades of this material are available depending of the level of ethoxylation performed, with repeat units (n) of polyethylene glycol varying between 2 and 20. Commercially it can be known as Brij 58 (when n=20) or Brij 56 (when n=10).
Uses
Different sources of media describe the Uses of 9004-95-9 differently. You can refer to the following data:
1. Polyethylene glycol hexadecyl ether is used as a surface active agent in cosmetics. Polyethylene glycol hexadecyl ether is a compound of derivatives of cetyl, lauryl, stearyl, and oleyl alcohols mixed with ethylene oxide.Non-ionic surfactant of the polyethylene glycol family. Polyethylene glycol hexadecyl ether is used as a solubilizer and emulsifying agent in foods, cosmetics, and pharmaceuticals, often as an ointment base, and also as a research tool.?Polyethylene glycol hexadecyl ether is used as an oil in water (O/W) emulsifier for creams/lotions, and a wetting agent.
2. Polyethylene glycol hexadecyl ether, or Brij 58, has been used in a study to assess properties of gemini-conventional surfactant mixtures and their effects on solubilization of polycyclic aromatic hydrocarbons. It has also been used in a study to investigate RNase-sensitive constraint of bacterial nucleoid structure.

Flammability and Explosibility
Nonflammable
Check Digit Verification of cas no
The CAS Registry Mumber 9004-95-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,0 and 4 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 9004-95:
(6*9)+(5*0)+(4*0)+(3*4)+(2*9)+(1*5)=89
89 % 10 = 9
So 9004-95-9 is a valid CAS Registry Number.

Liposome Enhanced Detection of Amyloid Protein Aggregates
Kocsis, Istvan,Sanna, Elena,Hunter, Christopher A.
, p. 647 - 650 (2021/02/06)
Thioflavin-T is used to image amyloid aggregates because of the excellent turn-on fluorescence properties, but binding affinities are low. By mounting multiple dye units on the surface of a vesicle, the binding affinity for α-synuclein fibrils is increased by three orders of magnitude, and the optical response is increased. Cooperative interactions of the dye headgroup and lipid with the protein provide a general strategy for the construction of multivalent amyloid probes based on vesicles.

Preparation method of higher fatty alcohol 2-alkoxy ethanol
-
Paragraph 0030; 0043; 0045-0048, (2021/08/25)
The invention provides a preparation method of higher fatty alcohol 2-alkoxy ethanol, and relates to the technical field of organic synthesis, higher fatty alcohol and sulfonyl halide are used as raw materials for cascade reaction, the higher fatty alcohol is completely converted into sulfonate under the action of alkali, and then the sulfonate is subjected to phase transfer reaction under the promotion of a phase transfer catalyst (the used phase transfer catalyst comprises quaternary ammonium salt or crown ether), sulfonate directly performs nucleophilic substitution reaction with ethylene glycol, and the reaction temperature is controlled to complete the reaction within half an hour to obtain the corresponding higher fatty alcohol 2-alkoxy ethanol. The method is low in raw material and reagent cost, simple in process operation, small in pollution, high in product yield and purity, and suitable for large-scale preparation.
