Problems solved by technology

[0007] In summary, the prior art generally uses oily ingredients containing core substances (such as essence) and wall material prepolymers as raw materials to synthesize microcapsules by emulsion polymerization, interfacial polymerization, original flavor polymerization, and sol-gel methods. , the core substance wrapped by it is obviously limited by its functional group, octanol water partition coefficient (ClogP), polarity, water solubility, or is sensitive to the polarity of the solvent that dissolves the core substance, and the selectivity of the prepared microcapsules is very limited
Although there are very few patented technologies to prepare microcapsules by mixing and aging the core substance (such as essence) solution with prefabricated microcapsules, although they are not limited by the functional groups during the polymerization reaction, they are still limited by the octanol content of the core substance (such as essence). The limitation of water partition coefficient or hydrophilic-lipophilic balance, and the presence of surfactants that cooperate with the core material and wall material system must be present during the mixing process, further increasing the application limitations of the encapsulation system

preparation example Construction

[0069] In a preferred embodiment of the present invention, the preparation method of the hollow polymer microspheres comprises the following steps: 1) preparing an oil-in-water microdroplet suspension; 3) at a certain temperature, drop the mixed solution of step 2) into the suspension of step 1), react, and form a cross-linked polymer shell on the surface of the micro-droplet; 4) control The temperature of the reaction system is further reacted at this temperature for a certain period of time to obtain hollow polymer microspheres with micropores on the surface.

[0070] The method further comprises the steps of:

[0071] 5) The product of step 4) is further processed as follows: flotation and drying.

[0072] Wherein, step 1) is specifically: firstly adding the organic solvent into the water phase system, dispersing the organic solvent in the water phase system under stirring, gradually raising the temperature, and preparing the oil-in-water micro-droplet suspension; wherein,...

Embodiment 1～6

[0197] Taking the fabric care agent as an example below, investigate the softening performance and fragrance retention performance of the care agent added with essence microcapsules. The formula tables and performance test results of Examples 1 to 6 are shown in Table 1 and Table 2. The surface of the microcapsules is selected. There are hollow polymer brittle microspheres or elastic microspheres with micropores, and the citronellol (comprising both left-handed and right-handed) with a ClogP value of less than 3.4 is selected for the citronellol wrapped in microcapsules. The citronellol is a terpene, Natural essential oils contain D- or L-citronellol and their racemates. D-citronellol is mainly found in rue oil, citronella oil and lemon eucalyptus oil; L-citronellol is mainly found in rose oil and geranium. Among the essential oils, both are colorless liquids with a sweet rose fragrance, and the aroma of the left-handed body is more elegant than that of the right-handed body. ...

Embodiment 7～12

[0204] Taking the fabric care agent as an example below, investigate the softening performance and fragrance retention performance of the care agent added with essence microcapsules. The formula tables and performances of Examples 7-12 are shown in Table 3 and Table 4. Hollow polymer brittle microspheres or elastic microspheres in the pores, and hexyl cinnamaldehyde with a ClogP value greater than 3.4 for the incense selection wrapped in microcapsules. Hexyl cinnamaldehyde is a light yellow liquid with a jasmine fragrance.

Abstract

The invention discloses care composition, a care agent as well as preparation methods and applications thereof. The care composition is prepared from components in percentage by mass as follows: 1wt%-50wt% of a surfactant and 0.01wt%-10wt% of microcapsules. The microcapsules for the preparation method of the care composition are added to a care agent system and can be deposited on the surfaces ofto-be-cared substances such as fabric, skin and hair or reserved in the to-be-cared substances such as gaps of fabric fibers in a physical absorption or chemical absorption manner. A selected core substance is not limited by functional groups, octanol-water distribution coefficient, polarity and water solubility; preferably, the surfactant is selected from biodegradable alkyl ester based quaternary ammonium salt and a novel green and environment-friendly nonionic surfactant (alkylethoxyglucoside), and the care composition prepared from the surfactant and the microcapsules through compounding is better in stability, can keep aroma for a long time and is greener and more environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of nursing products, and in particular relates to a nursing composition, a nursing agent and a preparation method and application thereof. Background technique [0002] In our daily life, we often find that after many cycles of wearing-washing-drying, the clothes or fabrics will become hard and sticky, which may be related to the softening components introduced in the process of fabric dyeing and finishing and post-treatment. It is related to the loss of softness caused by detachment from the surface of the fabric after multiple washings. If softener is added during the rinsing process of the clothes to supplement the surface of the fabric with softening ingredients, the softness of the fabric can be greatly improved and the phenomenon of fabric becoming hard and sticky can be reduced. In addition, fabric softeners usually add various fragrance components, and the fragrance molecules can be more adsorbed on...
