Эмульгаторы

[Alexa_Alexa]

Недавно зашла речь об агрессивности эмульгаторов.
Чтобы узнать агрессивность для кожи - надо знать гидрофильно-липофильный баланс эмульгатора: чем он больше, тем хуже для кожи. ГЛБ может быть от 0 до 20. В прямых эмульсиях он равен 9-12, а в обратных - 3,5-5,5.
Таблица значений ГЛБ для некоторых эмульгаторов:
Glycol Distearate HLB = 1
