AI Technical Summary

Problems solved by technology

The material has the following disadvantages: ①The material contains urea-formaldehyde resin, and urea-formaldehyde resin has poor heat resistance, poor weather resistance, formaldehyde release during use, and easy to decompose when encountering acid and alkali, which seriously affects its application; ②The material does not have functions ③ This material is filtered and dried, and agglomerated seriously, it is difficult to obtain submicron-sized essence microcapsules, and it is difficult to disperse and process again when used in other industries
Chinese patent CN104226211A adopts the spray drying process to prepare essence microcapsules by embedding essential oils with yeast cells. This material improves the agglomeration of microcapsules through spray drying, but the use of the material is also limited because the yeast cells are not heat-resistant and do not have functionality.

Abstract

The invention provides a heat-resistant, antibacterial and sun-proof camellia flower nanometer microcapsule with long-term slow release effect and a preparation method thereof. An essence capsule is characterized in that camellia flower oil is used as a core material, titanium dioxide and silicon dioxide are used as wall materials, and a sol-gel-spraying reaction method is adopted to prepare the heat-resistant, antibacterial and sun-proof camellia flower nanometer microcapsule with long-term slow release effect by one step. The essence capsule has the characteristics that the heat-resistant property is good, the antibacterial, sun-proof and weather-resistant properties are realized, the poison is avoided, the agglomeration amount is small, the content of impurities is low, and the re-dispersing processing is easy; the medical effects of clearing heat and dehumidification, dispelling wind and relieving itching, killing insects and detoxifying, clearing stomach and moistening intestines,restringing and nourishing skin, eliminating swelling and relieving pain, promoting eyesight and brightening hairs, enhancing elasticity and toughness of blood vessels, delaying atherosclerosis, enhancing intestine and stomach absorption function, promoting hormone excretion of endocrine glands, preventing degrading of neural functions, enhancing immunity of a human body, preventing and treatinghypertension, preventing and treating cardiovascular diseases and the like are realized; the heat-resistant, antibacterial and sun-proof camellia flower nanometer microcapsule can be widely applied tothe industries of textiles, daily chemicals, foods, medicines, face beautifying, health care and the like.

Description

technical field [0001] The invention relates to the field of essence and fragrance nanocapsules, in particular to a heat-resistant antibacterial and sunscreen camellia nanocapsule with long-term sustained release effect and a preparation method thereof. Background technique [0002] Flavors and fragrances are composed of a variety of volatile small molecular compounds. The main components are unstable and volatile. They are easily affected by heat and light during use and cause oxidative deterioration, which affects the quality of the final fragranced product. Camellia oil is a vegetable oil extracted from camellia flowers. It is mainly used in medicine, beauty and health care industries. It has the functions of clearing heat and dehumidification, expelling wind and relieving itching, killing insects and detoxifying, clearing stomach and intestines, astringent and moisturizing, reducing swelling and pain, and brightening eyesight. It can enhance the elasticity and toughness ...
