Polymethyloctylsiloxane is a synthetic, organosilicon compound that is predominantly used in cosmetics and personal care products. It functions as a skin conditioning agent, enhancing the skin's smoothness and providing a soft and silky touch. It is also known for its non-greasy texture and high resistance to water and heat. Despite being a silicone-based compound, it is generally deemed safe, non-irritating, and non-toxic for topical applications. However, there remains ongoing research and debate regarding the long-term effects of its use.

Check Digit Verification of cas no
The CAS Registry Mumber 68440-90-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,4,4 and 0 respectively; the second part has 2 digits, 9 and 0 respectively.Calculate Digit Verification of CAS Registry Number 68440-90:
(7*6)+(6*8)+(5*4)+(4*4)+(3*0)+(2*9)+(1*0)=144
144 % 10 = 4
So 68440-90-4 is a valid CAS Registry Number.
