Cross-linked natural gum resins, when inserted in shampooing product, result infallible to eliminate several metallic ions risky for hair keratin

Abstract

Aims of my research is to herald the method of eliminating Calcium and Magnesium ions that remain onto hair and scalp keratin after washing with common hard water and trivial shampooing products, but even of removing other metals as Lead, Silicon and Nickel ions which can be retrieved in manifold building materials like mortar, cement, concrete, pozzolans, limestone and asbest, most of workers throughout the world are directly involved with, because of their continuous contact with those chemical materials. I have selected twelve volunteers (workers who are directly in contact with building materials containing Calcium and Magnesium ions) and prayed them to use three types of shampooing products of my invention (containing special gum resins previously cross-linked in order to uptake or sorption the metallic ions) after having used, in precedence, trivial shampoos (bought at the same store) and used the same tap water, since they live all in the same town. I calculated the difference of quantities of Magnesium and Calcium that remain onto hair and scalp keratin, using a general and trivial shampoo respect to my products, apt to remove the same metallic ions. Results are satisfactory and encouraging.
