L-焦* 用途與合成方法
特點(diǎn)及用途 在人類皮膚中含有一種保濕功能的水溶性物質(zhì)——天然保濕因子,其組成大致為氨基酸(含40%)、焦*(含 12%)、無機(jī)鹽類(Na、K、Ca、Mg等含18.5%)、其它有機(jī)物 (含29.5%)。所以,焦*是皮膚天然保濕因子的主要組分之一,其保濕能力遠(yuǎn)超過甘油及丙二醇等。且無毒、無刺激,是現(xiàn)代護(hù)膚、護(hù)發(fā)化妝品的優(yōu)良原料。焦*還對(duì)*氧化酶的活性有抑制作用,從而阻止“類黑素”物質(zhì)在皮膚中沉積,對(duì)皮膚具有增白作用。對(duì)角質(zhì)有軟化作用,可用于指甲化妝品。除在化妝品中應(yīng)用外,L-焦*還可與其它一些有機(jī)化合物生成衍生物,在表面活性、透明光亮作用等方面具有特殊功效。也可用作表面活性劑,用于洗滌劑;化學(xué)試劑,用于外消旋胺的拆分;有機(jī)中間體。
