Abstract

The invention belongs to the field of daily use chemicals and discloses an oil-tea sunscreen cream and a preparation method thereof. The oil-tea sunscreen cream is prepared from the following components in parts by weight: 15-30 parts of tea oil fructose ester, 5-15 parts of a nano-tea polyphenol rare earth complex, 2-10 parts of stone needle, 2-10 parts of tea saponin, 1-5 parts of origanum oil and 30-75 parts of water. The preparation method comprises the steps of firstly preparing the tea oil fructose ester and the nano-tea polyphenol rare earth complex, crushing the stone needle into fine powder by a ball mill, mixing the fine powder with other raw materials in a formula proportion, and carrying out homogenization and emulsification, so as to obtain the oil-tea sunscreen cream. The oil-tea sunscreen cream has the effects of blocking sun, preserving moisture, resisting bacteria and activating skin through far infrared rays.

Description

technical field [0001] The invention belongs to the field of daily chemical products, and in particular relates to a camellia oleifera sunscreen and a preparation method thereof. Background technique [0002] Ultraviolet rays are extremely harmful to the human body. Long-term exposure to ultraviolet rays will not only easily lead to darkening of the skin, but also induce DNA mutations, leading to the occurrence of skin cancer. There are ultraviolet rays in sunlight, among which UVA (wavelength 320-420nm) part has strong penetrating power, can reach the dermis, and stimulate the production of melanin. Therefore, sunscreen products should also be used in the sun. [0003] At present, there are many sunscreen products on the market, which mainly work in two ways: physical sunscreen and chemical sunscreen. Physical sunscreens directly block ultraviolet rays with the help of zinc oxide, titanium oxide and other coverings, but due to the limited amount of use, the blocking effec...
