White Granule Emulsifier Steareth-21

White Granule Emulsifier Steareth-21 CAS NO 9005 00 9 Steareth-21 is a non-ionic surfactant that appears as white granules with an average degree of ethoxylation of 21. Its INCI name is Stealeth-21 and its CAS number is 9005-00-9. Due to its high HLB value (about 15-16), it is widely used in oil in water (O/W) systems and can provide reliable emulsification effects even in complex formulation environments. The packaging specification is adopted as 10kg/box, which is convenient for batch use. From a chemical perspective This ingredient is prepared by ethoxylation of stearyl alcohol, and contains 21 ethylene oxide units in the molecule, which gives it strong hydrophilicity. Therefore, it is very suitable for use as the main emulsifier or in combination with low HLB value emulsifiers such as Stealeth-2 as an auxiliary emulsifier. By adjusting Steareth-21, the balance of hydrophilic phase and lipophilic phase can be precisely adjusted, allowing the formulator to better control the stabili…
