Problems solved by technology

Such a preparation method has certain disadvantages: first, in the process of water phase entering into oil phase, or oil phase entering into water phase, a considerable part of the raw material sticks to the wall of the vessel and the pipeline, and cannot enter the subsequent preparation process, which makes the loss of raw material relatively large. Big
Second, due to the certain viscosity of the oil-phase raw material, a certain amount of oil-phase raw material will remain on the pipeline during the process of adding. Long-term use may lead to an increase in the attachment on the pipeline wall, and the aging degree of the pipeline will be significantly accelerated. , reduce the service life of the pipeline
Third, multiple containers and pipes need to be cleaned when cleaning the preparation equipment. While increasing the workload of workers, it also wastes and pollutes water resources and environmental resources.

[0018] The preparation method of the present invention comprises the following steps:

[0019] a. Weigh 1.5-5% of stearic acid, 1-4% of cetyl alcohol, 1-3% of monoglyceride, 0.5-2% of silicone oil, 3-9% of isopropyl palmitate, and 8-9% of glycerin by weight percentage. 12%, deionized water 61-84.4%, stir slowly in the container under heating, so that the temperature of the mixture rises to 60-80 ° C, until the solids in the mixture are completely melted, and the solution in the entire container is clear and transparent. Form stratification phenomenon, the upper layer is the oil layer, and the lower layer is the water layer;

[0020] b. Use a homogenizer to homogenize the solution at a speed of 10,000 rpm for about 3 minutes;

[0021] c. Put the whole container into water at 60-80°C for water bath defoaming;

[0022] d. Stir at room temperature until the temperature is lower than 45°C, then add barley extract and essence to the solution;

[0023] e. Continue to stir, make th...

Description

technical field [0001] The present invention relates to a kind of cosmetics or similar dressing preparations, more specifically to a natural whitening skin care product and a preparation method thereof. Background technique [0002] With the continuous expansion of the whitening cosmetics market, many famous cosmetics companies and research institutions have invested a lot of manpower and material resources in the development of new whitening chemicals. . Even the well-known brands of well-known companies will inevitably have worrying situations. For example, the SK-II brand under Procter & Gamble had an incident of excessive metal content in 2006, which made consumers wary of whitening products.
