Hypotaurine
　
Successful development is the centerpiece among anti-aging material of recent years.  HYPOTAURINE or 2-Aminoethanesulfinic acid (H2N-CH2CH2-SO2H) scavenges most effectively singlet oxygen which accelerates oxidization of skin and causes aging of skin.  The item also has high humectancy.Oxidization of skin begins with transformation of sebum into lipid peroxide under the influence of U.V.  The process is as follows ----- U.V. generates reactive oxygen and free radicals on the skin.  This reactive oxygen and free radicals oxidize sebum into lipid peroxide, which transmits oxidization to inner part of the skin.  Oxidization affects cells there so much that aging of skin goes on.  In this process even crucial cells for aging such as keratinocite and fibroblast suffer damage.  Thus the skin becomes roughened and loses elasticity due to lack of collagen.  The skin without elasticity changes gradually to be wrinkly skin
Oxidization of skin begins with oxidization of squalene, a component of sebum.  Further study proved that reactive oxygen and free radicals, above all singlet oxygen have much to do with oxidization of squalene.HYPOTAURINE was discovered as a sulfuric metabolite in animal body.  Now it is successfully synthesized and originally intended to humectant.  On the other hand researcher found it is likely to have anti-oxidant efficacy seeing its chemical structure. ----- HYPOTAURINE is recognized as a scavenger of singlet oxygen.  It proves 2 times more efficient than tocopherol acetate known as conventional scavenger of singlet oxygen.  For all high scavenging ability against singlet oxygen, HYPOTAURINE is stable enough to be used in cosmetics.  With humectancy as large as glycerine, HYPOTAURINE is a right material to be applied for skin care --- anti-aging products.
