FIELD: cosmetic industry.
SUBSTANCE: group of inventions relates to the field of cosmetic industry, namely, a composition of encapsulated fragrant substance for inclusion in a surfactant-containing medium containing at least one negatively charged amino-plastic microcapsule of a core-shell type dispersed in an aqueous dispersing medium, where a shell of the specified microcapsule of the core-shell type has cationic polyampholyte embedded in it, and the content of embedded cationic polyampholyte is in the range from 0.01 to 5% by wt. per the total weight of microcapsules and dispersing medium, it also relates to a composition of a non-suspension liquid detergent containing an anionic surfactant and a composition of encapsulated fragrant substance, it also relates to the use of cationic polyampholyte to facilitate the dispersion of a composition of encapsulated fragrant substance containing at least one negatively charged amino-plastic microcapsule of a core-shell type in a composition of a detergent, and it relates to a method for the formation of a composition of encapsulated fragrant substance, containing at least one negatively charged amino-plastic microcapsule of a core-shell type dispersed in a dispersing medium, where the specified method includes stages of: I) encapsulation of at least one drop containing fragrant substance into a shell containing crosslinked amino-plastic resin to form a suspension containing a dispersion of at least one negatively charged amino-plastic microcapsule of a core-shell type, and II) addition to the suspension, simultaneously or sequentially, of cationic polyampholyte, amino-aldehyde pre-condensate and crosslinking agent under conditions, in which pre-condensate and crosslinking agent react to form a matrix of crosslinked amino-plastic resin around the microcapsule of the core-shell type, where cationic polyampholyte is embedded in the matrix.
EFFECT: group of inventions provides an increase in the resistance of the composition of microcapsules of the core-shell type to aggregation due to the use of cationic polyampholyte embedded in the microcapsule shell.
