DL-Panthenol

DL-panthenol is a white powder that occurs as a combination of D-panthenol and L-panthenol. It is a provitamin and a racemic mixture of D and L forms of panthenol. The body can readily absorb this substance. After this absorption, it is readily converted into pantothenic acid or vitamin B5, which is a natural constituent of healthy hair and a substance that occurs in all living cells. This racemic mixture is 100% active when considering moisturization properties, improving hydration, reducing water loss, and maintaining skin elasticity and softness. However, if we apply it for skin epithelization, only the D form converts into vitamin B5 but not the L form. Therefore, this mixture shows only half of the physiological activity.
