Octoxynol-9, also known as octoxinol or polyethylene glycol p-(1,1,3,3-tetramethylbutyl)phenyl ether, is a nonionic surfactant and a member of the ethoxylated alkyl phenol family. It is widely used in various pharmaceutical and cosmetic applications as an emulsifier, solubilizer, and wetting agent. Octoxynol-9 is effective in solubilizing hydrophobic compounds, enhancing the stability of emulsions, and improving the solubility of drugs. It is also used as a detergent and a component in microemulsions. Due to its amphiphilic nature, it can interact with both water and oil, making it a versatile ingredient in the formulation of personal care products and medications.
The CAS Registry Mumber 9010-43-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,1 and 0 respectively; the second part has 2 digits, 4 and 3 respectively. Calculate Digit Verification of CAS Registry Number 9010-43: (6*9)+(5*0)+(4*1)+(3*0)+(2*4)+(1*3)=69 69 % 10 = 9 So 9010-43-9 is a valid CAS Registry Number.
