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.
