Embodiment 1

[0085] (1) Preparation of slow-release flavor popping beads matrix: take chitosan and dissolve it in 1% acetic acid solution, so that the concentration of chitosan is 0.1g / L, add lavender essence and Tween-80 to the chitosan solution , stir evenly to form an O / W emulsion, then dropwise add 0.5g / L sodium tripolyphosphate solution, stir and cross-link to obtain microcapsules; add xanthan gum to obtain a pop-bead matrix.

[0086] (2) Popping bead forming: mix the popping bead matrix with an equal volume of 2% calcium chloride solution, stir evenly and drop into 0.2% sodium alginate solution to obtain the product. Electron micrograph, particle size and thermogravimetric analysis of the prepared microcapsule quick-fried beads are as follows: figure 1 , figure 2 , image 3 shown.

Embodiment 2

[0088] (1) Preparation of slow-release flavor popping beads matrix: take chitosan and dissolve it in 0.5% acetic acid solution, so that the concentration of chitosan is 1g / L, add rose essence and lecithin in chitosan solution, stir Uniformly form an O / W emulsion, then add 0.5g / L sodium tripolyphosphate solution drop by drop, stir and cross-link to obtain the popping pearl matrix; add xanthan gum to obtain the popping pearl matrix.

[0089] (2) Bead forming: Stir the bead base and 10% calcium carbonate solution of equal volume and drop them evenly into 0.2% sodium alginate and 10% modified gelatin solution containing photoinitiator to obtain the product.

Embodiment 3

[0091] (1) Preparation of slow-release flavor popping beads matrix: take chitosan and dissolve it in 1% acetic acid solution, so that the concentration of chitosan is 3g / L, add sweet orange essence and Tween-80 to the chitosan solution , stir evenly to form an O / W emulsion, then add 1g / L sodium sulfate solution drop by drop, stir and cross-link to obtain the popping pearl matrix; add xanthan gum to obtain the popping pearl matrix.

[0092] (2) Popping bead forming: stir the popping bead base and 50% calcium chloride solution of equal volume and drop them evenly into 0.2% gelatin solution to obtain the product.

Abstract

The invention discloses a preparation method of a microcapsule burst bead. The preparation method comprises the following steps: mixing chitosan with a solvent to obtain a water phase, wherein the pH value of the water phase is greater than 4.3 and less than 6; adding an emulsifier and essence into the water phase, and conducting uniform stirring to obtain an emulsion; dropwise adding a cross-linking agent solution into the emulsion, and carrying out stirring for cross-linking to obtain a microcapsule; mixing the microcapsule with a stabilizer to obtain a burst bead matrix; and mixing the burst bead matrix with a calcium salt solution, and dropwise adding the obtained mixture into a wall material solution. The invention also discloses a laundry detergent. The laundry detergent comprises the microcapsule burst beads uniformly dispersed in a base solution of the laundry detergent. The invention also discloses bath foam. The bath foam comprises the microcapsule burst beads uniformly dispersed in a base solution of the bath foam. The invention also discloses a shampoo. The shampoo comprises the microcapsule burst beads uniformly dispersed in a base solution of the shampoo.

Description

technical field [0001] The invention relates to the technical field of daily chemical products, in particular to a preparation method and application of microcapsule explosive beads. Background technique [0002] With the development of science and technology society, people's basic life is guaranteed, and people begin to pursue a higher quality of life and a more lasting and rich sensory experience, which promotes continuous innovation and upgrading of products, and the requirements for the safety and sensory experience of fragrances are also getting higher and higher. Various essence beads have emerged as the times require, such as laundry beads. The existing laundry beads are made of concentrated laundry liquid wrapped in a water-soluble polymer film, which has the advantages of water saving, light weight, quantitative and easy to use, etc. In addition, there are functions such as clothing protection, softness, and fragrance retention on the market features.
