Slow-release moisturizing face cream and preparation method thereof

Abstract

The invention discloses a slow-release moisturizing face cream and a preparation method thereof. The face cream is prepared from the following components in percentage by mass of 5-15% of polyhydric alcohol, 1-5% of fatty alcohol, 2% of polydimethylsiloxane, 1-25% of grease, 0.1-10% of a skin-care active ingredient, 0.5-2% of an emulsifier, 0.2-2.8% of a pH regulator, 0.2-1.5% of an antioxidant, 0.2-2% of a thickening agent and the balance of water. The preparation method comprises the following steps of S1, weighing the raw materials; S2, mixing the grease, the fatty alcohol and the emulsifier, mixing a mixture with 30% of the total amount of the skin-care active ingredient, and carrying out heating and stirring until a mixture is dissolved to obtain an oil phase; S3, mixing the polyhydric alcohol, the pH regulator, the antioxidant, the thickening agent and the water, mixing a mixture with 30% of the total amount of the skin-care active ingredient, carrying out stirring until a mixture is completely dispersed, heating to 85 DEG C, and cooling to 80 DEG C after 5 minutes to obtain a water phase; S4, pouring the water phase into the oil phase, carrying out homogenizing, and cooling to 65 DEG C to obtain a dispersed phase; S5, adding silicone oil, and carrying out homogenizing to obtain a fourth mixture; and S6, cooling the fourth mixture to 45 DEG C, adding the remaining skin-care active ingredient, and cooling to 25 DEG C to obtain the face cream.

Description

technical field [0001] The invention relates to the related technical field of skin care products, in particular to a slow-release moisturizing face cream and a preparation method thereof. Background technique [0002] Face cream is a skin care product used on the face of the human body to care for the facial skin.

Problems solved by technology

[0003] Among the traditional texture creams, the paste is thick and oily, and has good moisturizing performance, but it is often not easy to absorb, and it is not suitable for oily skin, and it is not suitable for summer use; the paste is thin and easy to spread, and the use experience is more moisturizing , but at the same time, the moisturizing ability is generally lower than that of heavy creams, so it is not suitable for use in winter

[0004] With the gradual improvement of consumers' consumption level and demand, the efficacy and use experience of traditional facial creams can no longer meet consumers' more diverse and more precise demands. Today, what consumers need is good moisturizing performance and targeted at their own skin problems. more effective face cream

[0005] Existing functional face creams have the following disadvantages: First, it is impossible to add sufficient skin care active ingredients to the face cream and ensure the overall system stability of the face cream, and it is impossible to ensure that the active ingredients in the system can exert their maximum after use. The effectiveness of skin care should be absorbed by the skin as much as possible to reflect its efficacy; second, the stability of skin care active ingredients in the cream system cannot be guaranteed, because powerful skin care active ingredients are usually irritating, unstable, and photosensitivity , heat sensitivity and other characteristics that are not conducive to storage, these characteristics make it difficult to maintain long-term stability and strong efficacy output during the shelf life and the use period after opening until it is used up
