PEG-9 distearate, also known as polyethylene glycol-9 distearate, is a non-ionic surfactant derived from the esterification of polyethylene glycol (PEG) and stearic acid. It is a waxy, white solid with a melting point around 40-50°C and is soluble in most organic solvents. PEG-9 distearate is widely used in various industries, including cosmetics, pharmaceuticals, and lubricants, due to its emulsifying, solubilizing, and stabilizing properties. It helps to create stable emulsions, improve the solubility of active ingredients, and enhance the texture of formulations. Additionally, it is known for its low toxicity and good skin compatibility, making it a popular choice for personal care products.
The CAS Registry Mumber 109-34-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,0 and 9 respectively; the second part has 2 digits, 3 and 4 respectively. Calculate Digit Verification of CAS Registry Number 109-34: (5*1)+(4*0)+(3*9)+(2*3)+(1*4)=42 42 % 10 = 2 So 109-34-2 is a valid CAS Registry Number.
