Polysorbate 8, also known as Tween 8, is a nonionic surfactant commonly used in various industries due to its emulsifying, solubilizing, and wetting properties. Derived from sorbitan and oleic acid, this chemical is widely employed in pharmaceuticals, food, cosmetics, and industrial applications to stabilize emulsions, improve solubility, and enhance the dispersion of active ingredients. Polysorbate 8 is generally recognized as safe (GRAS) by the FDA and is considered non-toxic and non-irritating, making it a popular choice for a wide range of products.
The CAS Registry Mumber 9009-51-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,0 and 9 respectively; the second part has 2 digits, 5 and 1 respectively. Calculate Digit Verification of CAS Registry Number 9009-51: (6*9)+(5*0)+(4*0)+(3*9)+(2*5)+(1*1)=92 92 % 10 = 2 So 9009-51-2 is a valid CAS Registry Number.
