Description
2-Propenoic acid, 4-benzoylphenyl ester, commonly known as benzophenone-4, is a chemical compound that serves as a UV filter in the production of sunscreens and personal care products. It is designed to protect the skin from the harmful effects of UV radiation by absorbing and reflecting the sun's rays, making it an effective ingredient for sun protection. Benzophenone-4 is widely used in the cosmetic and personal care industry, although there are concerns about its safety and potential for skin irritation or allergic reactions in some individuals.
Uses
Used in Sunscreen and Personal Care Products:
2-Propenoic acid, 4-benzoylphenyl ester is used as a UV filter for its ability to absorb and reflect the sun's rays, providing effective sun protection to the skin. It is commonly included in sunscreen formulations due to its efficacy in blocking harmful UV radiation.
Used in Cosmetic Industry:
In the cosmetic industry, benzophenone-4 is used as an ingredient in various personal care products to enhance their sun protection capabilities. Its inclusion in formulations helps to prevent skin damage caused by exposure to the sun, making it a valuable component in skincare products.
Despite the concerns regarding its safety, benzophenone-4 remains a widely used chemical in the cosmetic and personal care industry due to its effectiveness in providing sun protection. However, it is essential to continue researching and monitoring its potential risks to ensure the safety and well-being of consumers.
Check Digit Verification of cas no
The CAS Registry Mumber 22535-49-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,5,3 and 5 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 22535-49:
(7*2)+(6*2)+(5*5)+(4*3)+(3*5)+(2*4)+(1*9)=95
95 % 10 = 5
So 22535-49-5 is a valid CAS Registry Number.

Photopolymerization and photophysical properties of amine linked benzophenone photoinitiator for free radical polymerization
Temel, Gokhan,Enginol, Burak,Aydin, Meral,Balta, Demet Karaca,Arsu, Nergis
, p. 26 - 31 (2011)
Synthesis of amine linked type II photoinitiator (BPDEA) was achieved in high yields and photopolymerization of mono and multiacrylate monomers was performed with this photoinitiator in the absence of a coinitiator. BPDEA is more effective than benzophenone (BP) with the coinitiator (MDEA) system under inert atmosphere in photoinduced free radical polymerization of acrylates.

An intermediate for preparing (meth)acrylated photoinitiators according to Formula (I): wherein: R1 is selected from the group consisting of hydrogen and a methyl group; A represents a group comprising at least one photoinitiating moiety; L represents a n+o-valent linking group comprising at least one carbon atom; n and o each independently represent an integer from 1 to 4; p is equal to 0 or 1; X represents a group selected from the group consisting of Cl, Br, I and R2SO3; and R2 represents an optionally substituted group selected from the group consisting of an alkyl group, an alkenyl group, an alkynyl group, an alkaryl group , an aralkyl group, an aryl group and a heteroaryl group. A method for the preparation of (meth)acrylated photoinitiators by β-elimination of HX from the intermediate according to Formula (I) is also disclosed.
