The dispersion of SLES is a crucial requirement in the manufacture of numerous consumer products. Sonic’s Sonolator Homogenizer is a unique answer for diluting and dispersing SLES into water to eliminate fish eye appearance and save on processing time.
SLES 70 is a very common ingredient in the personal care products and is used as the soap and surfactant in shampoo, body wash, conditioner, liquid soap, liquid detergents, and more. SLES 70 needs to be diluted prior to final use and to purchase the material in a pre-diluted state is costly. We commonly see the material diluted down to between 17.5% and 28%. The issue with diluting is that you can be left with fish eyes, or globules, of undispersed SLES. Most manufacturers place water and SLES into a mixing tank at the proper ratio and mix a finite amount for some period of time until the material is adequately dispersed. This is less than ideal because:
- It takes too long
- It requires material transfers to tank where air can be introduced
- It requires a costly and space-consuming batch mixing tank
- It requires intense mixing in the tank or re-circulation out of tank to get to a final mix
- It uses mechanical shear that imparts heat
