The arginine derivative of this invention can emulsify the oily and aqueous components uniformly to form a stable emulsion. It can form an O/W or W/O emulsion as desired, if the proportions of the oily and aqueous components are appropriately varied, or if another appropriate emulsifier is added. The emulsifier composition containing the arginine derivative of this invention provides, for example, cosmetics for the skin such as a milky lotion and a cream, medicines for external use such as an ointment, cosmetics for the hair such as a shampoo, a rinse, a hair treatment solution and a hair conditioner, and softeners. It is particularly useful when employed for cosmetics for the hair or softeners, since the arginine derivative is adsorbed by the hair, or fibers, such as of wool or cotton, and exhibits, among others, the following effects:
(1) It removes the roughness of the hair or fibers and renders them soft to the touch;
(2) It smoothens the hair or fibers and renders them easy to comb;
(3) It prevents the generation of static electricity which would otherwise cause the loosening of e.g. the hair;
(4) It gives a pleasant handle and an oily feel, such as a smooth or moist feel; and
(5) It is hardly irritating to the skin of the head or the eyes.
本发明的精氨酸衍生物可均匀地乳化油性和水性成分,形成稳定的乳液。如果适当改变油性成分和水性成分的比例,或添加另一种适当的乳化剂,它可以根据需要形成 O/W 或 W/O 型乳液。例如,含有本发明精氨酸衍生物的乳化剂组合物可提供乳状乳液和乳霜等皮肤用化妆品、软膏等外用药物、洗发水、洗发露、头发护理液和护发素等头发用化妆品以及软化剂。精氨酸衍生物可被头发或纤维(如羊毛或棉花)吸附,除其他外,还具有以下功效,因此特别适用于头发化妆品或柔顺剂:
(1) 它能去除头发或纤维的粗糙感,使其触感柔软;
(2) 抚平头发或纤维,使其易于梳理;
(3) 防止产生静电,否则静电会导致头发等松散;
(4) 手感舒适,有油腻感,如光滑或湿润的感觉;以及
(5) 对头部皮肤或眼睛几乎没有刺激。
