[0069] 1. Stability evaluation

[0070] (1) Instruments and equipment

[0071] DGG-9140A electric constant temperature blast drying oven, BCD-196H Rongshida refrigerator.

[0072] (2) Evaluation items

[0073] A: Heat resistance:

[0074] Adjust the DGG-9140A electric heating constant temperature blast drying oven to 45°C, put the sample to be tested, take it out after 24 hours, and after returning to room temperature, there is no phenomenon of discoloration, water separation, and stratification. Each product of embodiment 1-3 was observed by the above-mentioned method for one month, and no abnormality was found.

[0075] B: cold resistance:

[0076] Put the sample to be tested into the freezer of a Royalstar refrigerator (temperature -10 to -15°C), take it out after 24 hours, and after returning to room temperature, there is no phenomenon of discoloration, water separation, or stratification. The samples ...

Abstract

An oil-in-emulsion type foundation emulsion, made of the following raw materials: 0.3-5.0 parts by weight of PEG-30 dipolyhydroxystearate, 0.2-5.0 parts by weight of polyglycerin-3 diisostearate, and 8.0 parts by weight of oil phase -20.0 parts by weight, 5.0-30.0 parts by weight of powder, 40.0-75.0 parts by weight of water phase and auxiliary materials. The preparation method includes: mixing PEG‑30 dipolyhydroxystearate with 1 / 3 oil, heating to 70‑80°C to obtain component I; adding the powder to polyglyceryl‑3 diisostearate and In the remaining 2 / 3 of the oil phase, disperse until uniform to obtain component II; slowly add component I to the water phase in a vacuum stirring tank, heat to 80-85°C, stir to form an emulsion; slowly add the emulsion to component II In the process, stir and homogenize; add auxiliary materials, discharge below 40°C. The emulsion is low in oil, high in moisturizing, high in powder loading capacity, excellent in smearing, long-lasting in moisture, not easy to remove makeup and has good stability.

Description

technical field [0001] The invention relates to a cosmetic product and a preparation method thereof, in particular to a foundation product, belonging to the technical field of cosmetics and make-up. Background technique [0002] At present, emulsions containing powder mostly use water-in-oil (W / O) or oil-in-water (O / W) emulsification technology, and there are also glycerin-in-oil (G / O) and oil-in-oil (O / O) emulsification technologies. . The advantages and disadvantages of each dosage form are as follows: [0003] Oil-in-water (O / W) type emulsion: heat-resistant and cold-resistant, good stability, refreshing skin feeling, poor water resistance, suitable for the preparation of skin care lotion, cream, oil-in-water type foundation products, less powder load, easy to smear The smoothness is poor, and the powder is easy to take off makeup; [0004] Water-in-oil (W / O) emulsion: The current technology has the problem that the cold resistance effect is not as good as that of oil-...
