FIELD: chemistry.
SUBSTANCE: group of inventions relates to cosmetic products, detergent and cleaning composition. Disclosed is dimeric surfactant
where X – (-CH2-)n, n from 2 to 8, (-CH2-CH2-S-S-CH2-CH2-), (-CH2-CH2-O-CH2-CH2-), (-CH2-CH2-C6H4-CH2-CH2-), (-CH2-CH2-C6H4-C6H4-CH2-CH2-); Y – -CH2-, -CH2-CH2-, -CH2-CH2-CH2-; R1 for anionic - -SO3Na, -OSO3Na, -COONa; for zwitterionic – ammonium group with a combination of substitutes of the row: methyl, ethyl, propyl, allyl, -CH2-CH2-O-CH2-CH2-, -CH2-CH2-CH2-CH2-CH2-, -CH2-CH2-N(CH3)-CH2-CH2- and negatively charged substitutes of the row: carboxymethyl, sulphomethyl, phosphomethyl; for cationic ions – an ammonium group with a combination of substitutes of the series: methyl, ethyl, benzyl and counter ions of the series: chloride, bromide, methyl sulphate; R2 – aliphatic substitutes with long chain C9-C17. Also disclosed is a method of producing a dimeric surfactant, an active surfactant composition, a detergent composition and a cosmetic composition.
EFFECT: group of inventions enables to create commercially available dimeric surfactants capable of increasing the effectiveness of detergent and cosmetic compositions in small amounts.
