The invention discloses microcapsules, a preparation method thereof, cleaning composition containing the microcapsules and a
cleaning agent. The cleaning composition is prepared from the following components by
mass: 5wt%-90wt% of a surfactant and 0.01wt%-10wt% of the microcapsules wherein the microcapsules contain hollow
polymer microspheres with microporous channels in the surface and substanceswith fragrance and / or special smell and / or special functions; the substances with fragrance and / or special smell and / or special functions are not limited by functional groups, ClogP (
partition coefficient octanol / water) and water
solubility; the surfactant in the cleaning composition is preferably a novel green and environment-friendly
nonionic surfactant (
alkyl ethoxy polyglycosides), and the cleaning composition and the
cleaning agent with excellent performance and environmental friendliness are obtained from the surfactant and the microcapsules through compounding and widely used in the fields of fabric cleaning agents, tableware cleaning agents, floor cleaning agents, carpet cleaning agents,
skin cleaning agents, hair cleaning agents,
deodorant and the like.
