The user feedback of the example 1 and the example 3 is better, but the addition amount of various raw materials in the example 3 is larger, the process flow time is longer, and the cost is higher, so the example 1 is a better embodiment, the small amount of user feedback of the example 2 has certain irritation, which is possibly related to the lower content of the extract, but the addition amount of the astragalus extract is not too large; the comparative example 1 adopts the conventional substances such as sodium alginate, sodium hyaluronate and glycerin as the skin care liquid, has certain irritation and poor moistening feeling, and thus the user experience can be effectively improved by compounding the plant extracts; the comparative example 2 does not contain the modified iron oxide, has certain irritation compared with the example, but has certain improvement on the skin moistening effect compared with the comparative example 1, but is weaker than the example, which shows that the unmodified iron oxide has certain effect on improving the effect of the skin lotion.
The examples 1 to 3 have certain effects of moistening skin and improving the water content of skin, are obviously superior to the comparative example 1, and show that the astragalus extract has an important effect of improving the skin; comparative example 1 also has a certain skin moisturizing effect, but the effect is not good, which shows that the astragalus extract and the compounding of the astragalus extract and other traditional Chinese medicines have a remarkable skin moisturizing effect.
In the embodiments 4 and 5, the astragalus extract has different dosage of various substances, and the influence on the moisture content of the skin is obvious, which shows that the preparation process of the astragalus extract and the compounding of the astragalus extract and the nano oxide have important functions on improving the skin care effect.
In examples 6 and 7, the manufacturing process of the modified iron oxide and the addition amount of part of the raw materials are different, and the influence on the skin water content is also obviously different, so that the manufacturing process parameters of the modified iron oxide have obvious change on the skin water content, the skin water content increase rate of example 6 is weaker than that of example 2, and the influence of the manufacturing process is larger than that of the addition amount of the modified iron oxide to a certain extent.
