preparation example Construction

[0063] The present invention also provides the preparation method of the antibacterial microemulsion described in the above technical scheme, comprising the following steps:

[0064] Dissolving the tea extract in water to obtain an aqueous phase;

[0065] Dissolving the gallnut extract in a co-emulsifier to obtain a gallnut extract solution;

[0066] firstly mixing the gallnut extract solution, emulsifier and cinnamon extract to obtain an oil phase;

[0067] The water phase and the oil phase are mixed for a second time to obtain the bacteriostatic microemulsion.

[0068] The present invention first provides cinnamon extract, gall extract and tea extract. The source of the cinnamon extract, gall extract and tea extract is not particularly limited in the present invention, and conventional commercial products can be used or extracted and prepared; when the cinnamon extract and gall extract are prepared by means of extraction When using tea extract, the extraction method is pr...

Embodiment 1

[0136] Utilize steam distillation method (solid-liquid ratio 50:1, extraction time is 30min) to extract the leaves and bark of cinnamon, obtain cinnamon extract;

[0137] Utilize reflux extraction method (solvent is 65% ethanol aqueous solution of mass concentration, the ratio of material to liquid is 18:1, the extraction temperature is 85 ° C, the extraction time is 8 min, and the extraction is repeated 3 times) to extract the gall; the filtrate obtained by filtration is in Distilled under reduced pressure at 40°C for 35min, freeze-dried at -50°C for 24h to obtain gall extract;

[0138] Use solvent extraction method distillation method (solvent is deionized water, material-to-liquid ratio 25:1, extraction temperature is 65 ℃, extraction time is 45min, and extraction is repeated 4 times) to extract tea leaves, and the extracted product is filtered; The obtained filtrate was distilled under reduced pressure at 50°C for 40min and then freeze-dried at -50°C for 24h to obtain tea ...

Embodiment 4

[0219] By mass percentage, 10% moisturizing agent (0.1% sodium hyaluronate, 4% butanediol, 5.9% glycerin), 1% skin conditioner (0.2% allantoin and 0.8% DL-panthenol) , 0.12% rheology modifier (xanthan gum), 0.02% chelating agent (disodium EDTA), 0.5% solubilizer (PEG-60 hydrogenated castor oil) and 88.26% deionized water at a temperature of 85 Stir for 5min under the condition of 10000r / min rotation speed to obtain primary moisturizing water;

[0220] The primary moisturizing water and 0.1% of the antibacterial microemulsion prepared in Example 1 were stirred evenly to obtain moisturizing water.

Abstract

The invention belongs to the technical field of daily chemical products, and particularly relates to a bacteriostatic microemulsion, a preparation method and application thereof, moisturizer, moisturizing lotion, moisturizing cream and a preparation method thereof. The invention provides a bacteriostatic microemulsion. The bacteriostatic microemulsion comprises the following components in percentage by mass: 1-15% of cinnamon extract, 0.5-2% of gallnut extract, 0.5-4% of tea extract, 20-80% of an emulsifier, 2-20% of a co-emulsifier and 4-75% of water. The antibacterial microemulsion provided by the invention can effectively inhibit growth of gram-positive bacteria, gram-negative bacteria, saccharomycetes and molds, and different antibacterial active substances are matched according to a certain proportion, so that synergistic interaction among the antibacterial active substances can be realized, and a broad-spectrum antibacterial effect is achieved. The bacteriostatic components in the bacteriostatic microemulsion provided by the invention are natural plant extracts, so that the irritation to human skin is small, and the use safety of cosmetics can be improved.

Description

technical field [0001] The invention belongs to the technical field of daily chemical products, and in particular relates to a bacteriostatic microemulsion, a preparation method and application thereof, a moisturizing water, a moisturizing emulsion, a moisturizing cream and a preparation method thereof. Background technique [0002] With the continuous development of social economy, people's quality of life is constantly improving, which also means that consumers' pursuit of quality cosmetics is also increasing. Cosmetics usually act on the human body, which also requires absolute safety of cosmetics to ensure the health of users. In order to inhibit the growth and reproduction of microorganisms in cosmetics, it is generally necessary to add preservatives to ensure that the properties of cosmetics are stable, relatively prolong their shelf life, and will not deteriorate due to external pollution after they are opened and used. These microorganisms will deteriorate the cosme...
