Embodiment 1
[0050] Embodiment 1: The preparation method of dry skin physical radiation protection sunscreen cosmetic provided by the embodiment of the present invention, it comprises the following steps:
[0051] (1) Preparing raw materials: each component and weight percentage of raw materials are as follows:
[0052] Nano barium sulfate powder 17%,
[0053] Nano Zinc Oxide Powder 4%,
[0054] Nano silver powder 0.05%,
[0055] Nano Pearl Powder 1.5%,
[0056] 4-aminobenzoic acid 2.5%,
[0057] Vaseline 70%,
[0058] Butanediol 2.2%,
[0059] Tartaric acid 1.05%,
[0060] Olive oil 1.7%;
[0061] (2) Preparation of petrolatum liquid: Weigh the corresponding amount of petrolatum according to the ratio of step (1), heat the petrolatum to 81-85° C. to melt it into a liquid state, and keep it at a constant temperature;
[0062] (3) Preparation of mixed solution I: add the corresponding proportion of butanediol to liquid vaseline, stir at 81-85°C for 30 minutes, and mix well to prepar...
Embodiment 2
[0083] Embodiment 2: The preparation method and the product of dry skin physical radiation protection sunscreen cosmetics provided by the present invention are basically the same as in Example 1, except that:
[0084] Each component of described raw material and percentage by weight thereof are as follows:
[0085] Nano barium sulfate powder 15%,
[0086] Nano Zinc Oxide Powder 5.6%,
[0087] Nano silver powder 0.04%,
[0088] Nano Pearl Powder 1.3%,
[0089] 4-aminobenzoic acid 2.4%,
[0090] Vaseline 71%,
[0091] Butanediol 2.0%,
[0092] Tartaric acid 1.16%,
[0093] Olive oil 1.5%.
Embodiment 3
[0094] Embodiment 3: The preparation method and the product of dry skin physical radiation protection sunscreen cosmetic provided by the present invention are basically the same as Embodiment 1 and 2, and its difference is:
[0095] Each component of described raw material and percentage by weight thereof are as follows:
[0096] Nano barium sulfate powder 15.5%,
[0097] Nano Zinc Oxide Powder 4%,
[0098] Nano silver powder 0.04%,
[0099] Nano Pearl Powder 1.2%,
[0100] 4-aminobenzoic acid 2.3%,
[0101] Vaseline 71.5%,
[0102] Butanediol 2.1%,
[0103] Tartaric acid 1.36%,
[0104] Olive oil 2.0%.
[0105]By carrying out test experiments on the products of the above examples, the experimental report obtained shows that the cosmetics provided by the present invention have an absorption rate of more than 99.5% to about 280-400 nanometers of ultraviolet rays, and the total efficiency of absorption and reflection of radiation such as mobile phones and computers can be...
