The present invention relates to N-polyhydroxyalkyl-amino acids of the formula ##STR1## wherein R.sub.1 represents a phenylene or a group of the general formula --CHR.sub.3 --, wherein R.sub.3 represents hydrogen, alkyl, benzyl possibly substituted by a hydroxyl group, hydroxyalkyl, mercaptoalkyl, methylthioalkyl, aminoalkyl, polyhydroxylalkylaminoalkyl, carboxyalkyl, guanidinoalkyl, N-polyhydroxyalkylguanidinoalkyl or a ureidoalkyl group, R.sub.2 represents a CH.sub.2 OH or COOH group, m stands for the integers of 3 or 4 and n for the integer 0, if m = 3, when R.sub.2 is COOH, or 4, or for the number 1, if m = 3 and R.sub.2 represents a CH.sub.2 OH group, their alkali metal salts or possibly substituted ammonium salts; as well as the process of preparing the same and skin care and protection agents containing an effective amount of said N-polyhydroxyalkyl-amino acids.
本发明涉及公式为##STR1##的N-多羟基烷基-氨基酸,其中R.sub.1代表苯基或一般式--CHR.sub.3--的基团,其中R.sub.3代表氢、烷基、苄基可能被羟基基团取代、羟基烷基、巯基烷基、甲硫基烷基、氨基烷基、多羟基烷基氨基烷基、羧基烷基、胍基烷基、N-多羟基烷基胍基烷基或尿素基烷基,R.sub.2代表CH.sub.2OH或COOH基团,m代表3或4的整数,n代表整数0,如果m = 3,则当R.sub.2为COOH或4时,或者当m = 3且R.sub.2代表CH.sub.2OH基团时,n代表数字1,它们的碱金属盐或可能被取代的铵盐;以及制备它们的过程和含有有效量的N-多羟基烷基-氨基酸的皮肤护理和保护剂。
