Examples 1 to 6 and comparative examples 1 to 12

Examples 1 to 6 and comparative examples 1 to 12 each provide a moisturizing skin care product mainly comprising a base, water and a moisturizing ingredient.

The base materials of examples 1-6 and comparative examples 1-12 are the same in formulation, selected ingredients are shown in table 1, the proportion of each ingredient in the moisturizing skin care product is shown in table 2, and the balance is water and moisturizing ingredients.

TABLE 1

TABLE 2

The proportions of the moisturizing components of examples 1 to 6 and comparative examples 1 to 12 are shown in table 3; in table 3: cyclopentadimethylsiloxane (and) trimethylsiloxysilicate are purchased from mayian under the model "SS 4230", poly (tripeptide-6) is purchased from viqi under the model "water-carrying protein peptide"; the sodium hyaluronate used is macromolecular sodium hyaluronate with a molecular weight in the range of 120-130 WDa. The percentages in table 3 are mass percentages.

TABLE 3

Referring again to Table 2, sodium hyaluronate, deionized water, CARBOPOL 981, and NIPAGIN M were used as phase A materials;

cyclopentadimethylsiloxane (and) trimethylsiloxy silicate, 15# white oil, MERKUR 500, Arlacel 170, EMERCOL MY, NIPASOL M as phase B raw materials; PC 2000 is a C-phase raw material; NEOLONE PH 100 and poly (tripeptide-6) as D phase materials.

As shown in Table 3, for the comparative examples without cyclopentadecyldimethylsiloxane (and) trimethylsiloxysilicate or poly (tripeptide-6), no phase B or D starting material was added.

The moisturizing skin care products of examples 1-6 and comparative examples 1-10 were prepared as follows:

mixing the raw materials of the phase A, heating to 80 ℃, and keeping the temperature for later use;

mixing the raw materials of the phase B, and then heating to 80 ℃; adding the mixed phase A into phase B, homogenizing, cooling to 70 deg.C, adding the phase C, mixing, cooling to 45 deg.C, adding the phase D, stirring, and discharging.

Examples of the experiments

Carrying out moisturizing efficacy test verification on the moisturizing skin care products of examples 1-6 and comparative examples 1-12, and evaluating the moisturizing function of 16 groups of moisturizing emulsion products by detecting the moisture content of the skin on the inner side of an arm;

the moisture content of the skin on the inner side of the arm after each moisturizing skin care product was measured before use, 1 hour after use, 3 hours after use, 8 hours after use, and 24 hours after use using a skin moisture tester, and blank control was performed, and the test results are shown in table 4.

TABLE 4

As can be seen from the data in table 4: the moisture retention of comparative examples 1-10 were all improved from the blank, but the improvement was not significant and decreased faster; as can be seen from comparative examples 1-10, the moisture content of the skin 24h after application is less different from the moisture content of the skin before application; comparative examples 6, 9 and 10 significantly increased the moisture content of the skin 1h after application, but the moisture content of the skin after 24h was less different from the moisture content of the skin before application; comparative examples 11 and 12 had an increase in moisturizing performance, but the skin was less hydrated after 24 h.

And the moisture retention of the examples 1 to 6 is remarkably increased, and 24h is kept moisture for a long time. The independent (cyclopentadimethylsiloxane, trimethylsiloxysilicate) or poly (tripeptide-6) has insignificant increase in the moisture retention of sodium hyaluronate and low durability; the moisture retention performance of the sodium hyaluronate can be obviously improved after the three raw materials are compounded; it can be seen that the durability of the moisturizing is better for examples 5 and 6 than for examples 1-4; after 24 hours of use, the moisture content of the skin was higher, indicating that the moisturizing performance of the aquatic products of examples 1-6 was better.
