Lactobionic acid amide compositions and their use

A method of synthesizing a lactobionic acid amide composition comprising lactobionic amides produced from the reaction of lactobionic acid and a mixture of primary fatty amines containing at least 30 percent by weight fatty amines having a chain length of 14 to 18 carbon atoms, said method comprising reacting lactobionic acid or a reactive lactobionic acid derivative with a fatty amine mixture obtained from a naturally occurring fatty acid mixture and containing at least 30 percent by weight fatty amines having a chain length of 14 to 18 carbon atoms.

A rinsing or cleaning composition comprising:

• a) an effective detergent, fabric softening, emulsifying, foam-stabilizing or thickening amount in the range from 1 to 80 percent by weight, based on the total weight of said formulation, of a surface active lactobionic acid amide composition comprising lactobionic amides produced from the reaction of lactobionic acid and a mixture of primary fatty amines obtained from a naturally occurring fatty acid mixture and containing at least 30 percent by weight fatty amines having a chain length of 14 to 18 carbon atoms, and
• b) from 20 to 99 percent by weight of at least one conventional vehicle or adjuvant ingredient for rinsing or cleaning compositions.
