About this ingredient

It is a functional component, not a skincare active. In soap formulas it provides hardness and cleansing properties. Pregnancy safety. Systemic absorption through intact skin is negligible and there is no evidence of harm. It can be used during pregnancy and lactation. Tolerance. In a formula with adjusted pH the irritation potential is low, but soap formulas with an alkaline pH can dry out dry and sensitive skin.
