Properties of N-acyl-N-methyltaurate(AMT), including surface active properties, cutaneous effects, influence on hair, and application to liquid type hair shampoo, are reviewed.
It has been found that AMT exhibit considerably high safety on skin in comparison with typical surfactants. As the result of cutaneous effects, the reduction of the amounts of dandruff was observed when using AMT shampoo.
In addition, AMT shows weaker action on the desintegration of hair cuticle.
Consequently, AMT can be a good surfactant as a detergent for the hair and scalp(skin).
On the other hand, cutaneous effects and physico-chemical properties of anionic/amphoteric surfactants mixed system, were investigated.
It has been found that these physico-chemical results were in good correlation with those pbtained by cutaneous effects. The synergistic reductions in cutaneous effects were observed as well as physico-chemical results.
These findings have promoted the development of hair shampoo composed of AMT.
