Abstract : The patent describes compositions which are mixtures of a hydrocarbon wax in equal to minor proportion by weight with mixed isomers of long chain alkylamine salts of long chain alkyl or alkenylsuccinic acid long chain alkylmonoamides. The compositions are water repellent and may be used to provide a transparent water repellent film on optical glass surfaces which are coated with an antireflection coating such as magnesium fluoride.
