Polyethylene glycol stearate

Polyethylene glycol distearate, commonly known as thickener 638, was esterified with polyethylene glycol 6000 and stearic acid. 638 is relatively insoluble in water, and the usual method is to dissolve it in hot water and then add it to other feed liquids. The addition of detergent is 0.2-0.5%, that is to say, 100kg needs 0.2-0.5kg, which can be dissolved in about 5kg of hot water and then added to the feed liquid. 638 itself is relatively insoluble in water, and the residual stearic acid content of 638 produced by small manufacturers is too high, and it is even more insoluble in water. Therefore, adding 638 to detergent with low active substance content often leads to poor transparency and poor thickening effect. Personally, I suggest that this thickener should not be used in bulk detergent products with low active substances. Manufacturers producing low-priced detergents are often small in scale, lacking the strength and experience of purchasing raw materials, and it is difficult to buy genuine raw materials. It is suggested that the limited cost should be used for the blade and basic surfactant components. He is not suitable as a thickener for detergents. If he wants to be a detergent, he should use 658 thickener.
