Performance test

The products prepared in examples 1-12 and comparative examples 1-4 were tested for cosmetic hygiene indicators according to GB/T29665-2013 skin care emulsion, each product conforming to the specifications of cosmetic hygiene Specification.

The products obtained in examples 1-12 and comparative examples 1-4 were subjected to stability tests: the gradient of the centrifugal speed condition is as follows: the centrifugal test was carried out at 2500rpm and 2800rpm for 30min to see if the product had delamination and oil-out, and the results are recorded in Table 1.

High temperature and cold resistance test: the products prepared in examples 1-12 and 1-4 were placed in an incubator at 50 ℃ and-18 ℃, the products were taken out to the incubator at 25 ℃ at regular intervals and fixed points every week, after 1 hour, whether oil outlet and layering phenomenon occurred or not was observed, if no unstable phenomenon occurred, the products were put back to continue the test, and after two months, the products were taken out every 3 days until oil outlet and layering phenomenon occurred, the days when oil outlet and layering phenomenon occurred were recorded, and the results are recorded in table 1. The products prepared in examples 1-12 and 1-4 were subjected to a temperature cycling test: the product was heated to 48℃at a temperature of-18℃at a heating rate of 3-5℃per minute, then cooled to room temperature, and then the above-mentioned operation was repeated three times, and the oil outlet and delamination of the product were observed, and the results are shown in Table 1.

Grading various results, wherein 0 represents no layering and no oil discharge; "1" means that delamination and oil extraction occurred slightly, "2" means that little delamination and oil extraction occurred, and "3" means that more delamination and oil extraction occurred.

TABLE 1

It can be seen from examples 1 to 12 in combination with Table 1 and FIG. 1 that the foundation liquid prepared by the present application has a silky and novel coating feel, and the product has excellent stability, does not show the phenomenon of water-oil separation for a long time at a high temperature of 50 ℃ and a low temperature of-18 ℃, and has excellent high temperature resistance and cold resistance.

As can be seen by combining examples 1-5 and combining Table 1, the centrifugal stability of the product is better by reasonably adjusting the amount of each raw material component, and the cyclic temperature stability of the product can be improved to a certain extent by selecting the cyclopenta-dimethicone and the dimethicone as the siloxane polymer. It can be seen from the combination of examples 5-12 and Table 1 that optimizing the components and amounts of the stabilizer and the neutralizing agent, adjusting the components and amounts of the preservative, both improves the stability of the product to some extent, since the neutralizing agent adjusts the viscosity of the aqueous phase to have a certain adsorptivity, so that the aqueous phase and the oil phase are uniformly mixed to form a stable carbomer suspension system, which has a silky and novel smear feeling when smeared. The stabilizer can enable the carbowave suspension system to form a stable interface film, balance the stability of the system, reduce layering phenomenon of products, effectively improve the suspension stability of toner and reduce sediment after the products stand.

In example 10, phenoxyethanol and octylglycol are used as preservatives, but the ratio of the two is poor, so that the product has poor stability in temperature cycle, and after three temperature cycles of-18 ℃ to 50 ℃, the product is slightly layered and oil is discharged. In example 11, only octanediol was used as a preservative, and the stability of the product of example 11 was also reduced, so that it was found that the preservative could synergistically improve the stability of the product with other materials in specific components and amounts. In example 12, only chamomile hydrosol and verbena hydrosol are adopted as the composite humectant, so that the silkiness of the product is reduced when the product is smeared, the use feeling of consumers is reduced, the mixing uniformity degree of water phase and oil phase is poor, and the product is slightly layered and oil-out after three temperature cycles of-18 ℃ to 50 ℃.

As can be seen from the combination of example 8 and comparative examples 1 to 2 and Table 1, the stability of the product is remarkably reduced regardless of the lack of the stabilizer or the neutralizer in the raw materials, a small number of layering and oil-out phenomena occur under the condition that the centrifugal speed is 2500rpm, a large number of layering and oil-out phenomena occur under the condition that the centrifugal speed is 2800rpm, and the high temperature resistance and cold resistance of the product are also poor, because under the action of the stabilizer, after the water phase and the oil phase are uniformly mixed, a stable interfacial film can be formed, the stabilizer can balance the stability of the system, the layering phenomenon of the product is reduced, and meanwhile, the stabilizer can effectively improve the suspension stability of the toner. Under the action of the neutralizing agent, the carbomer forms transparent gel with certain viscosity, so that the mechanical strength of the interfacial film of the carbomer suspension system can be effectively enhanced, and the stability of the product can be improved by cooperation of the carbomer and the stabilizing agent. Therefore, the absence of the neutralizing agent or the stabilizer has a significant effect on the stability of the product.

By combining the embodiment 8 and the comparative example 3 and combining the table 1, it can be seen that the composite humectant adopts butanediol and pentanediol, and the alcohol substances can only play a certain role in moisturizing, and the composite humectant of the application can adjust the interfacial force between the water phase and the oil phase, and can be matched with other raw materials in a synergistic way, so that the mixing uniformity degree of the water phase and the oil phase is improved, a stable carbowave suspension system with a certain mechanical strength is formed, the stability of the product is assisted to be improved, the product can have a silky and novel smearing feeling, and the product has good moisturizing property and good market competitiveness. It can be seen from the combination of example 8 and comparative example 4 and the combination of table 1 that during the mixing of the aqueous phase and the oil phase, the oil phase is directly mixed with the aqueous phase and homogenized at a lower rotational speed, the uniformity of the mixture of the product obtained is poor and the stability of the product is significantly reduced, whereby it is seen that the aqueous phase and the oil phase need to be stirred under specific conditions and homogenized at a constant rotational speed to form a stable carbowave suspension system, instead of an oil-in-water system or a water-in-oil system.

The present embodiment is merely illustrative of the present application and is not intended to be limiting, and those skilled in the art, after having read the present specification, may make modifications to the present embodiment without creative contribution as required, but is protected by patent laws within the scope of the claims of the present application.
