14529-40-9 Usage
Uses
Used in Cosmetic and Personal Care Industry:
CETETH-10 is used as an emulsifying agent for its ability to stabilize and improve the texture of creams, lotions, and other skincare formulations. It helps in creating a smooth and consistent product that is easy to apply and absorbs well into the skin.
CETETH-10 is used as a solubilizing agent for enhancing the spreadability and absorption of active ingredients in skincare products. This allows for more effective delivery of beneficial compounds to the skin, improving the overall performance of the product.
CETETH-10 is used for its safety and low skin irritation potential, making it suitable for a wide range of skincare products, including those designed for sensitive skin. Its non-ionic nature contributes to its compatibility with various other ingredients, further expanding its applications in the formulation of personal care products.
Check Digit Verification of cas no
The CAS Registry Mumber 14529-40-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,5,2 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 14529-40:
(7*1)+(6*4)+(5*5)+(4*2)+(3*9)+(2*4)+(1*0)=99
99 % 10 = 9
So 14529-40-9 is a valid CAS Registry Number.

Combinatorial synthesis of PEG oligomer libraries

Page/Page column 10, (2010/02/15)
A simple chain-extending approach was established for the scale-up of the monoprotected monodisperse PEG diol materials. Reactions of THP-(OCH2CH2)n—OMs (n=4, 8, 12) with a large excess of commercially available H—(OCH2CH2)n—OH (n=1-4) under basic conditions led to THP-(OCH2CH2)n—OH (n=5-15). Similarly, Me-(OCH2CH2)n—OH (n=4-11, 13) were prepared from Me-(OCH2CH2)n—OMs (n=3, 7, 11). For the chain elongation steps, 40-80% yields were achieved through extraction purification. PEG oligomer libraries I and II were generated in 50-95% overall yields by alkylation or acylation of THP-(OCH2CH2)n—OH (n=1-15) followed by deprotection. Alkylation of Me-(OCH2CH2)n—OH (n=1-11, 13) with X—(CH2)m—CO2R (X=Br or OMs) and subsequent hydrolysis led to PEG oligomer library III in 30-60% overall yields. Combinatorial purification techniques were adapted to the larger-scale library synthesis. A total of 498 compounds, each with a weight of 2-5 g and a minimum purity of 90%, were synthesized.
