  • Patent number: 5352389
    Abstract: The invention discloses compositions in the form of aqueous solutions or O/W emulsions for the cleaning of skin, scalp and hair, characterized in that they contain from 0.5 to 5% w/v of at least one water soluble organic base chosen in the group consisting of low molecular weight saturated aliphatic alkylamines, their hydroxy derivatives, low molecular weight primary alkylenediamines, basic aminoacids. Said water soluble organic base are buffered at pH 7-9. The cleaning efficacy of said preparations may be increased by adding lipases in a quantity ranging from 0.1 to 1% w/v. According to a further embodiment of the invention, said compositions can be comprised of detergents in a quantity not exceeding 4% w/v. The compositions are endowed of the property of cleaning the skin in a delicate manner, with a good local tolerability.
