The ethylene glycol stearate dissolves or emulsifies after heating in the surfactant composite, and lens crystals appear during the cooling process, thereby producing a pearlescent luster. It can be used in liquid detergent products to produce a distinct pearlescent effect and increase the viscosity of the product. It also could moisturize the skin, nourishe hair and protects against static electricity. It has good compatibility with other types of surfactants, and can reflect its stable pearlescent effect and thickening conditioning function. It has no irritation to the skin, no damage to the hair. In contrast, EGDS produces a stronger pearlescence, and EGMS produces a finer pearl.
