Amino acid fluoroalkyl carbamates of formula R-(CH2)n-O-CO-NR1-CHR2-(CH2)p-COOH (I) are new. R = 4-20C perfluoroalkyl; R1 = H or 1-4C alkyl; R2 = H, 1-4C alkyl, (CH2)m-COOH, -CH2OH or CH(OH)Me; m = 1 or 2; n = 0-4; p = 0 or 1. 8 Cpds. (I) are specifically claimed e.g.: N-2-F-octyl ethyloxycarbonyl- beta -alanine. (I) is present in an amt. of 0.001-30 (pref. 0.05-15) wt.%. The compsn. may also contain 0-15 wt.% of another surfactant. |
