4-(1,1,3,3,5,5-Hexamethyl-hexyl)-phenol, also known as Octocrylene, is a widely used organic compound in the chemical industry. It is a colorless to pale yellow liquid with a molecular formula of C20H32O and a molecular weight of 288.47 g/mol. 4-(1,1,3,3,5,5-Hexamethyl-hexyl)-phenol is primarily employed as a UV filter in sunscreens and other cosmetic products, as it effectively absorbs ultraviolet (UV) radiation, protecting the skin from harmful sun exposure. Octocrylene is characterized by its hexamethyl-hexyl side chain, which contributes to its stability and photostability, making it a popular choice for sun care formulations. It is also known for its low potential to cause skin irritation, which is an important consideration in the development of personal care products.
The CAS Registry Mumber 5806-65-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,0 and 6 respectively; the second part has 2 digits, 6 and 5 respectively. Calculate Digit Verification of CAS Registry Number 5806-65: (6*5)+(5*8)+(4*0)+(3*6)+(2*6)+(1*5)=105 105 % 10 = 5 So 5806-65-5 is a valid CAS Registry Number.
