Description

A kind of moisturizing skin care lotion and preparation method thereof

Technical field:

The invention relates to a moisturizing skin care emulsion and a preparation method thereof, in particular to a moisturizing skin care emulsion containing various plant extracts and a preparation method thereof.

Background technique:

"Water-locking function" is one of the important functions of moisturizing lotion. Only when the cells are kept hydrated and filled can the skin be rejuvenated, thus satisfying the moisturizing effect. Numerous beauty and skin care products focus on various skin care effects, but they fail to start with the key to skin care, which is to lock in water to achieve moisture. Even the moisturizing lotion currently on the market cannot achieve the effect of long-lasting hydration to keep the skin moisturized. Facing the miraculous effects of skin care lotions advertised by manufacturers, beauty-loving women usually buy them without hesitation, but they suffer the misfortune of "Waterloo". The fundamental reason for the ineffective or ineffective moisturizing effect lies in some added ingredients in these lotions that are potentially harmful to the skin. Human skin is weakly acidic. In order to protect the weakly acidic film on the surface of the skin, a weakly acidic skin care lotion should be used. Many lotions contain a small amount of oil stone ester to increase the lubricating feeling of the lotion, but this substance is easy to clog pores, resulting in dry skin and lack of water.

Invention content:

The first technical problem to be solved by the present invention is to provide a moisturizing skin care emulsion with good moisturizing properties.

The 2nd technical problem to be solved by the present invention is the preparation method of above-mentioned moisturizing skin care lotion.

The technical problem solved by the present invention is: a kind of moisturizing skin care lotion, 73g of moisturizing skin care lotion contains the following substances:

Described comfrey corn oil is prepared by the following method:

Weigh an appropriate amount of comfrey, soak it with 3-10 times corn oil, soak it for 2-3 days, put it into an ultrasonic cleaner, heat it to 30-60°C, extract it ultrasonically for 1-4 hours, and filter it with double gauze .

Described rose corn oil is prepared by the following methods:

Weigh an appropriate amount of roses, soak them with 3-10 times corn oil, soak them for 5-10 days, and filter them with double gauze.

Each drop is equivalent to 0.04-0.08ml.

Described ethylparaben alcohol solution is that the ethylparaben of 6 grams is dissolved in the 100ml ethanol that volume concentration is 75%.

The preparation method of described a kind of moisturizing skin care lotion, comprises the following steps:

a) Weigh 0.05-0.5g of carbomer, disperse it in 20-50ml of distilled water, fully swell to form a clear and transparent liquid, drop 2-10 drops of 20% triethanolamine solution to adjust the pH value to neutral, and form a gel Glue A;

b) Weigh 0.01-0.5g of sodium alginate, disperse it in 2-10ml of distilled water, and fully swell it into a transparent gel B;

c) Weigh 0.1-2g of comfrey corn oil, 0.5-5g of sweet almond oil, 1-2g of grape seed oil, 2-10ml of glycerol oleic acid citrate (GOC), and 0.1-2ml of rose corn oil in container 1 , heated in a water bath at 70-90°C;

d) Measure 1-5ml of glycerin, 1-6ml of propylene glycol, and the remaining distilled water in container 2, and heat in a water bath at 70-90°C;

e) Add the mixture in container 2 into container 1 in a thin stream and mix evenly. After stirring for 10-30 minutes, add gel A, gel B, 0.1-2g elastin, and 0.5-2g glycine , D-panthenol 0.2-1g, sodium lactate 0.2-1g, 6% ethylparaben alcohol solution 0.2-0.7ml, stir evenly, and obtain moisturizing skin care lotion.

It has obvious effects on dry, sensitive and aging skin. It can enhance the activity of elastic fibers and collagen fibers, dilute spots, promote the decomposition and metabolism of melanin, and achieve the effect of truly whitening skin without traces.

Elastin has skin care effects. Severe damage to cell DNA by free radicals, aging of collagen fibers and elastic fibers caused by ultraviolet rays, excess toxins deposited on the skin by smoke exhaust, excessive consumption of high-fat and acidic foods, endocrine disorders and decreased metabolism, all these factors accelerate skin elasticity The loss of a large amount of protein is the root cause of skin aging (sagging, wrinkles, roughness). Elastin has extraordinary penetrating power, which is easy for the skin to directly absorb elastin. It has a high viscosity, soft and does not clog pores, ensures a high degree of water-locking cells, and has an obvious moisturizing effect on the skin. Elastin is a good supplement of various amino acids and proteins lost by the skin, which can activate cells, repair damage, resist aging and wrinkle, revitalize the complexion, and maintain the best shape of the skin.

There are two isomers of panthenol, L-panthenol and D-panthenol, and only D-panthenol is effective. Pantothenic acid is a component of coenzyme A. When the human body lacks pantothenic acid, the skin keratosis is abnormal, resulting in peeling. Panthenol is absorbed by the body and converted into pantothenic acid to play a physiological role. The caring action on the skin manifests itself as a deeply penetrating moisturizer, stimulates the growth of epithelial cells, promotes wound healing and acts as an anti-inflammatory.

Sodium lactate is a natural moisturizing factor, and a quarter of the composition of human skin stratum corneum is sodium lactate. Sodium lactate used in cosmetics can form a hydration film with other chemical ingredients to prevent skin moisture from volatilizing, keep the skin in a relaxed and moist state, and prevent wrinkles.
