Problems solved by technology

But above-mentioned beauty care cleansing tape also has the following disadvantages: the adhesive force of medical glue cannot be adjusted; the surface cleaning effect on wrinkled or uneven skin is not ideal; there is no moisturizing effect, and the use feeling of dry skin is not good when using this tape
However, the production process of this product is more complicated, the cost is higher, and the effect of cleaning solid dirt adhered to the surface by special dirt is not obvious
[0005] In the prior art, there is a lack of a cleaning product with simple production, low cost and good cleaning effect

Embodiment 1

[0048] Raw material formula and mass percentage ratio:

[0049] Polyvinyl alcohol (weight average molecular weight is 88000) 5%, boric acid 0.8%, water 93.998%, sorbic acid (preservative) 0.002%, glycerin 0.2%.

[0050] making process:

[0051] Step 1, 5 grams of polyvinyl alcohol with a weight-average molecular weight of 88,000, 0.8 grams of boric acid, and 0.002 grams of methyl p-hydroxybenzoate are ground and fully stirred to obtain a mixture powder;

[0052] Step 2: Add 0.2 grams of glycerin to 100 grams of water at 85°C, stir evenly, add the mixture powder, stir thoroughly, and wait for the chemical reaction to take place;

[0053] Step 3, after the reaction finishes, the unreacted water is separated from the gel;

[0054] Step 4. Dry the free water on the surface of the gel at room temperature to obtain the hand gel.

[0055] The hand gel prepared by the above method has strong adhesion, and can effectively remove dirt and metabolites on the skin surface through adhesio...

Embodiment 2

[0057] Raw material formula and mass percentage ratio:

[0058] 6% of polyvinyl alcohol with a weight average molecular weight of 30,000, 1% of boric acid, 91.998% of water, 0.002% of phenoxyethanol as a preservative, and 2% of glycerin.

[0059] making process:

[0060] Step 1. Grinding 6 grams of polyvinyl alcohol with a weight-average molecular weight of 30,000, 1 gram of boric acid, and 0.002 gram of phenoxyethanol and fully stirring to obtain a mixture powder;

[0061] Step 2: Add 2 grams of glycerin to 95 grams of water at 80°C, stir evenly, add the mixture powder, stir fully, and wait for its full chemical reaction;

[0062] Step 3, after the reaction finishes, the unreacted water is separated from the gel;

[0063] Step 4. Dry the free water on the surface of the gel at room temperature to obtain the hand gel.

[0064] Compared with Example 1, the molecular weight of polyvinyl alcohol in Example 2 is more preferred, so through the use of 50 trial personnel, it is ge...

Embodiment 3

[0066] Raw material formula and mass percentage ratio:

[0067] 6% of polyvinyl alcohol with a weight average molecular weight of 14,000, 1% of boric acid, 91.998% of water, 0.002% of phenoxyethanol as a preservative, and 2% of glycerin.

[0068] making process:

[0069] Step 1. Grinding 6 grams of polyvinyl alcohol with a weight-average molecular weight of 30,000, 1 gram of boric acid, and 0.002 gram of phenoxyethanol and fully stirring to obtain a mixture powder;

[0070] Step 2: Add 2 grams of glycerin to 95 grams of water at 80°C, stir evenly, add the mixture powder, stir fully, and wait for its full chemical reaction;

[0071] Step 3, after the reaction finishes, the unreacted water is separated from the gel;

[0072] Step 4. Dry the free water on the surface of the gel at room temperature to obtain the hand gel.

Abstract

The invention discloses a hand cleaning gel, and a preparation method and a use thereof. The hand cleaning gel comprises 0.5-15% by mass of polyvinyl alcohol, 0.5-5% by mass of boric acid and / or borax, 0-15% by mass of an additive, and 65-99% by mass of water, wherein the content of the additive is not zero, the additive comprises a sterilization antiseptic, an essence and a moisture retention component, and the hand cleaning gel is a hydrogel in state. The hand cleaning gel has a simple preparation method and a low cost; the hand cleaning gel has a strong adhesion, and substances comprising scales, metabolites and the like on the skin surfaces and in the deep slits can be effectively removed through rubbing a proper amount of the hand cleaning gel in hands, so the hand cleaning gel has a deep cleaning effect; and the hand cleaning gel has the advantages of no need of water, use convenience, no liquid residue, good skin endophilicity, smooth and comfortable skins after use, carrying convenience, and repeated use. The hand cleaning gel is especially suitable for travels, outdoor works, and founders, miners and builders having the scales which are difficult to remove.

Description

technical field [0001] The invention relates to the technical field of hand cleaning products, in particular to a hand gel and its preparation method and application. Background technique [0002] At present, in the field of hand cleaning products, commonly used products include washing type and disposable type. In various occasions of traveling and outdoor work, the use of water-washing type cleansing products is greatly restricted. In addition, washing-type cleansing products also have defects such as complicated use, time-consuming, and water-consuming. Commonly used no-rinse cleansing products generally include liquid no-clean products and wet wipes, which are more convenient to use, but these two types of no-clean products often have problems with residual liquid and dirt, and when cleaning special dirt adhered to the surface The effect is not obvious on solid dirt. [0003] In the prior art, the patent number is: ZL 200720116496.4, which provides a beauty care and s...
