Problems solved by technology

However, water-based products can only contain water-soluble active ingredients, and there is no way to add oil-soluble active ingredients, which leads to a relatively single effect of cosmetics
Under normal pH or low ion concentration, the suspension system mixed with water and oil can basically maintain good stability, but under the condition of low pH environment or high ion concentration, these suspension systems will soon undergo stratification, oil production, etc. Phenomenon

preparation example Construction

[0057] The present application also provides a preparation method for the above-mentioned stable suspension system, which specifically includes:

[0058] (1) Stir and mix the thickener and water evenly to form a water phase, in which the water phase solution needs to be heated to 70°C to 90°C (specifically, it can be 70°C, 75°C, 80°C, 85°C, 90°C or 70°C ~90℃), ensure that the thickener and water are fully mixed together;

[0059] (2) Heat the oil to 70°C-90°C (specifically, it can be 70°C, 75°C, 80°C, 85°C, 90°C or any value between 70°C-90°C), then mix it with the water phase solution, put Homogenize in a homogenizer to form an emulsion;

[0060] (3) When the temperature of the above-mentioned emulsion is lowered to less than or equal to 50°C, then add at least one of the acidic substance and the ionic substance into the emulsion, and continue homogenizing in a homogenizer to obtain a stable suspension system.

[0061] In one embodiment, the stable suspension system also in...

Embodiment 1

[0069] This embodiment provides a stable suspension system, which includes 0.1% lactic acid, 2% agarose, 10% caprylic triglyceride, and water as the balance, assuming that the total mass of the stable suspension system is 100%.

[0070] The specific preparation method is as follows: weigh 87.9g of water, add 2g of agarose, put it into a water bath and heat it to 80°C, stir evenly to form a water phase; heat 10g of caprylic triglyceride to 80°C to form an oil phase; Mix it with the oil phase and put it into a homogenizer for homogenization to obtain an emulsion, continue stirring until the temperature drops to 40°C, add 0.1g of lactic acid to the emulsion, and continue homogenizing to obtain a stable suspension system.

Embodiment 2

[0072] With embodiment 1, difference is that the consumption of lactic acid is 3%.

Abstract

The invention provides a stable suspension system, a preparation method thereof and cosmetics, and relates to the field of cosmetics. The stable suspension system comprises the following components in percentage by mass: at least one of0.1-6% of an acidic substance and 0.1-20% of an ionic substance, 0.1-5% of a thickening agent, 1-40% of grease and the balance of water, wherein the thickening agent comprises at least one of agar, agarose, gellan gum and a sphingomonas fermentation extract. The preparation method of the stable suspension system comprises the following steps: mixing the thickening agent with water to form a water phase; mixing grease with a water phase to form an emulsion; and mixing at least one of an acidic substance and an ionic substance with the emulsion to obtain the stable suspension system. The invention further provides a cosmetic, and the raw materials of the cosmetic comprise the stable suspension system. Tests show that the stable suspension system has good stability in a low pH environment and / or high ion concentration, the preparation method is simple and easy to operate, and the stable suspension system can be applied to cosmetics.

Description

technical field [0001] The application relates to the field of cosmetics, in particular to a stable suspension system, a preparation method thereof and cosmetics. Background technique [0002] With the development of the cosmetics industry, more and more different types of cosmetics appear on the market, such as lotion, lotion, cream and so on. In the formulation of cosmetics, most of them contain one or more thickeners to achieve the purpose of improving the appearance of cosmetics and improving the stability of cosmetics. Different thickening suspension systems not only affect the appearance and stability of the product, but also have a great impact on the use feeling and functional performance of the product. [0003] At present, acid brushing is a very popular skin care method. Its essence is to use strong exfoliating acidic substances to exfoliate the skin and restore the skin to a youthful and healthy state. Generally, the pH of brush acid products is relatively low,...
