Abstract
The pH‐dependent surface properties of a gelatin–alkenylsuccinic acid anhydride derived surfactants, containing an oligopeptide residue and alkenyl groups, were studied. The surface properties examined included surface tension, contact angle, emulsifying power, and fluorescence properties. The results showed that the surface activities of gelatin derivatives and their detergent properties for T/W fabrics are improved at low pH. These improved features make gelatin‐derived surfactants suitable for use as cleaning agents for lime‐degradable substrates such as hair and wool. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci, 2007
