[0048] The present invention will be described in detail below in conjunction with the embodiments.

[0049] The first aspect of the present invention provides an emulsion, preferably an emulsion containing a softener, wherein the emulsion comprises the following components by mass percentage:

[0050] Phase A: dipotassium glycyrrhizinate 0.3-0.7%, water 85-89%.

[0051] Phase B: propylene glycol 2-3%, glycerin 0.5-1.5%, methylparaben 0.05-1%.

[0052] Phase C: 2-4% ethylhexyl palmitate, 0.02-0.04% propylparaben, 1-3% emulsifier, 0.5-1.5% thickener.

[0053] Phase D: softener 1-3%, extract composition 0.1-0.3%, marigold extract 1-2%, essence 0.01-0.03%, methylisothiazolinone 0.05-0.2%.

[0054] In some embodiments, the emulsion comprises the following components by mass percentage:

[0055] Phase A: dipotassium glycyrrhizinate 0.5-0.7%, water 85-88%.

[0056] Phase B: propylene glycol 2-2.5%, glycerin 0.5-1.0%, methylparaben 0.05-1%.

[0057] Phase C: 2-3% ethylhexyl palmitate, 0.02-0.03% propylparaben, 1-1.5% emulsifier, 0.5-1.0% thickener.

[0058] Phase D: softener 2-3%, extract composition 0.1-0.2%, marigold extract 1-1.5%, fragrance 0.01-0.02%, methylisothiazolinone 0.05-0.1%.

[0059] In some embodiments, the emulsion comprises the following components by mass percentage:

[0060] Phase A: 0.7% dipotassium glycyrrhizinate, 86.5% water;

[0061] Phase B: propylene glycol 2.5%, glycerin 0.5%, methylparaben 0.05%;

[0062] Phase C: 3% ethylhexyl palmitate, 0.03% propylparaben, 1.5% emulsifier, 0.5% thickener;

[0063] Phase D: 3% softener, 0.1% extract composition, 1.5% marigold extract, 0.02% fragrance, 0.1% methylisothiazolinone.

[0064] In some embodiments, the dipotassium glycyrrhizinate has anti-inflammatory and soothing effects. This ingredient is widely used in skin care products, can relieve skin inflammation and discomfort, and has a certain moisturizing effect. In the present invention, the addition ratio of dipotassium glycyrrhizinate is controlled between 0.3% and 0.7% to ensure that the anti-inflammatory and soothing effects of the product are optimal.

[0065] In some embodiments, in the phase C, the emulsifier includes cetyl alcohol and coconut glucoside; the mass ratio of cetyl alcohol to coconut glucoside is 2.5-3:7.

[0066] In some embodiments, the thickener is Sepigel 305.

[0067] In some embodiments, the emollient comprises amodimethicone.

[0068] In some embodiments, the amino group content of the aminopolydimethylsiloxane is 0.04-0.06%.

[0069] Preferably, the softener is Run SI EA-8168P.

[0070] It is understandable that among the softeners, amino-terminated polydimethylsiloxane can increase the lubricity and softness of the product, making the wet wipes more comfortable during use. Amodimethylsiloxane avoids the problem that non-amino-terminated silicone oil has a strong smell after being added, which is not suitable for use by infants and young children.

[0071] In some embodiments, the extract composition includes wild chrysanthemum extract, golden chamomile extract, camellia seed extract, and licorice extract; the mass ratio of the wild chrysanthemum extract, golden chamomile extract, camellia seed extract and licorice extract is 1:1:1:1.

[0072] It is understood that in the present invention, the marigold extract has anti-inflammatory and antioxidant effects. Calendula is believed to have good soothing and repairing effects on the skin, can help reduce skin inflammation, and has a certain antioxidant effect, which helps to delay skin aging. In the present invention, the addition ratio of the marigold extract is controlled between 1% and 2%, and the preferred addition amount is 1.5% to ensure that the product has good anti-inflammatory and antioxidant effects.

[0073] Preferably, the calendula extract can be obtained by extraction according to conventional methods in the art, and preferably, the calendula extract is extracted by glycerol. More preferably, the calendula extract is extracted by glycerol, and the extraction temperature is 80-100°C. Specifically, the calendula extract is obtained by adding glycerol to the calendula raw material, heating and stirring at 80-100°C. The calendula extract of the present invention can be a liquid, and most preferably, the calendula extract is purchased from the calendula extract NP of Beijing Oriental Miaosen Biotechnology Co., Ltd. It can be understood that when glycerol is used to extract calendula, glycerol can extract both high and low polar substances, and can also extract oil-soluble components, which has significant advantages over water as an extractant; compared with flammable and explosive extraction solvents such as ethanol and isopropanol, the extraction is safer. The extract composition is obtained by mixing wild chrysanthemum extract, golden chamomile extract, camellia seed extract, and licorice extract in a mass ratio of 1:1:1:1. In the present invention, the calendula extract is mixed with an extract composition containing wild chrysanthemum extract, golden chamomile extract, camellia seed extract and licorice extract. The above components are all natural extracts, have high safety, are more suitable for infants and young children, and the prepared emulsion has good antibacterial, anti-inflammatory, moisturizing and repairing effects.

[0074] It is to be understood that, unless otherwise stated, the raw materials in the present invention are all commercially available.

[0075] The second aspect of the present invention provides a method for preparing the emulsion containing a softening agent according to the first aspect, the preparation method comprising the following steps:

[0076] S1: Prepare phase A, phase B, phase C, and phase D respectively. The details are as follows:

[0077] Phase A is obtained by mixing dipotassium glycyrrhizinate and water according to the mass percentage of the above components, and heating and stirring at 82-85° C.; Phase B is obtained by mixing propylene glycol, glycerin, and methylparaben, keeping warm for 15-20 minutes for disinfection and defoaming, and setting aside; Phase C is obtained by mixing ethylhexyl palmitate, propylparaben, an emulsifier, and a thickener; Phase D is obtained by mixing a softener, an extract composition, a marigold extract, an essence, and methylisothiazolinone.

[0079] The third aspect of the present invention provides an application of the emulsion described in the first aspect or the emulsion prepared by the preparation method described in the second aspect, wherein the emulsion is used for non-woven fabrics or for infant skin care.

[0080] In some embodiments of the present invention, the application to the non-woven fabric is to immerse the non-woven fabric in the emulsion, or to apply the emulsion to the surface of the non-woven fabric by spraying or the like.

[0081] In some embodiments of the present invention, the emulsion is applied to the surface of diapers or is used as an impregnation liquid in the preparation of a substrate for wipes.

[0082] In some embodiments, the emulsion is applied to the surface of the diaper by spraying the emulsion on the surface of the diaper in contact with the skin, and then drying to obtain the diaper containing the emulsion component of the softener. The spraying area is preferably an area that will be soaked by urine. Preferably, the spraying can be performed at intervals to ensure the breathability of the diaper.

[0083] In some embodiments, the emulsion is used to prepare wipes, including infant wipes, adult wipes, cleaning wipes, etc. The specific method is to spray the emulsion on a wipe substrate, such as a surface of a non-woven fabric, or immerse the wipe substrate in the emulsion.

[0084] In some embodiments, the wipes are wet wipes, and the wet wipes substrate is prepared by diluting the prepared emulsion with water, and then soaking the cut non-woven fabric substrate material, such as polyester non-woven fabric or other substrates, such as cotton, acrylic, etc., in the above aqueous solution, taking it out and drying it in a 40°C oven for 30 minutes to obtain a wet wipes substrate.

The blank sample was the test fabric without the addition of the emulsion, and the test sample was the sample treated with the emulsion prepared in different embodiments and comparative examples.

[0161] During the experiment, first weigh the towels used (each towel must have a substantially consistent weight). Take a clean beaker of the same size, take the emulsions prepared in different embodiments and comparative examples, accurately prepare a test solution with a concentration of 5wt%, put the test fabric in at room temperature, soak for 30 minutes, take it out and dehydrate it, and then dry it at 40°C.

[0162] During the test, the towels were folded into the same thickness and in the same direction, and the test samples were compared with the blank samples. During the test, 5 people with certain experience and sensitive hands were asked to evaluate them respectively. The results were statistically compared using a scoring method, with 5 points as the highest score and 1 point as the lowest score. The higher the score, the better the softness. The test results are shown in Table 2.

[0163] At the same time, the effect of oiling rate on the product when spraying was determined. The fabric was sprayed with the emulsion prepared in Example 1 and dried. According to the different spraying amounts, test samples with oiling rates of 0.2%, 0.5% and 1% were obtained, respectively, which were recorded as Test Example 1, Test Example 2 and Test Example 3. The sensory panel was asked to evaluate the softness and slipperiness, and the results were statistically compared by scoring, with 5 points as the highest score and 1 point as the lowest score. The higher the score, the better the softness and slipperiness. The results are shown in Table 1. Among them, the oiling rate is the mass fraction of the effective component in the dried sample to the sample weight. For example, if the weight of the dried sample is 100g and the content of the effective component is 0.2g, the oiling rate is 0.2%.

[0165]

[0166]

[0167] By comparing the oiling rates of the dried samples, it can be seen that when the oiling rate is 1%, the softness and slipperiness of the samples are better than those when the oiling rates are 0.2% and 0.5%.

[0168] (2) Antistatic test method

[0169] The antistatic property adopts FZ / T 01042-1996 standard, and the specific steps are: take the emulsions prepared in different embodiments and comparative examples respectively, accurately prepare 100 mL of aqueous solution with a concentration of 5 wt%, put three cut polyester pieces (specification of 45×45 mm) into the test solution of different concentrations and soak them for 12 hours, take them out and dry them in a 40°C oven for 30 minutes, then continue to balance for 12 hours under atmospheric conditions of air humidity of 35±5% and temperature of 20±2°C, and use YG(B)342D fabric induction static tester to measure the static property of polyester fabric. Before starting the static tester, fix the fabric on the sample disk, and start the measurement after clearing and resetting. Through the high-voltage electric field, the rotating polyester fabric is discharged regularly to induce static electricity, thereby detecting the static voltage (the voltage to the ground caused by the relatively stable accumulation of charges on the pattern) and the half-life (the time required for the static voltage to decay to half of the initial value). After the measurement, the sample disk stops rotating and the static voltage and half-life displayed on the instrument are recorded. Repeat the measurement three times for each tissue and take the average value. The smaller the static half-life, the better the antistatic property. Among them, the static voltage refers to the voltage to the ground caused by the relatively stable accumulation of charges on the pattern, and the half-life refers to the time required for the static voltage to decay to half of the initial value. The test results are shown in Table 2.

[0171] formula Softness level Electrostatic half-life / S Example 1 2.9 16.32 Example 2 3.0 12.59 Example 3 3.3 9.35 Example 4 3.4 6.49 Example 5 3.6 4.64 Comparative Example 1 1 414.09

[0172] As can be seen from the above table, the example formulas of different wet wipes emulsions with the addition of aminodimethicone have significantly improved softness and antistatic properties compared to Comparative Example 1 without the addition of aminodimethicone, and in Examples 1-5, the softness and antistatic properties are improved as the amount of aminodimethicone added increases.

[0173] (3) Hydrophilic penetration + reverse osmosis test:

[0174] A hydrophilic nonwoven fabric sample without coating was taken as a blank control, and the emulsion prepared in Example 1 was sprayed on the surface of the hydrophilic nonwoven fabric sample at intervals, the oiling rate of Test Example 1 was 0.2%, the oiling rate of Test Example 2 was 0.5%, and the oiling rate of Test Example 3 was 1.0%. The hydrophilic penetration time MSTT-3+ reverse osmosis performance was determined using GB / T 24218.14-2010 Textiles and Nonwoven Fabrics Test Methods, Part 14: Determination of the Dewetting Amount of Coating Materials. Each sample was tested three times, and the results are shown in Table 3 below.

[0175] Table 3 Test results of hydrophilic penetration + reverse osmosis of nonwoven fabrics containing the emulsion of Example 1

[0176]

[0177] It can be seen from the above table that the emulsion of the present invention is used on the hydrophilic nonwoven fabric sample without affecting the hydrophilicity of the hydrophilic nonwoven fabric itself.

[0178] The formula of the emulsion of the present invention combines the functions of cleaning and care, so that the wet wipes product can provide moisturizing and soothing while cleaning the skin; the proportion of each component is carefully controlled to ensure the soothing and care effect of the product on the skin, while requiring the stability and safety performance of the formula to be excellent, and the preparation process is simple and easy to operate, suitable for large-scale production.

[0179] The present invention uses the prepared emulsion to prepare wet wipes substrates by rationally adding and controlling the proportion of each component, which not only improves the cleaning effect, but also provides meticulous care for the skin, so that the skin is moisturized and soothed while being cleaned, thus meeting the consumer's demand for high-quality wet wipes products. It is understandable that the application of the emulsion includes but is not limited to baby wet wipes substrates, adult wet wipes substrates, cosmetic cleansing wet wipes substrates, etc., and can also be applied to personal care.

[0180] When the emulsion of the present invention is used in care products such as diapers, the feel and flexibility of the products such as diapers are improved, the friction of the products such as diapers on the skin is reduced, the skin can be better protected, and the absorption of urine is not affected.

[0181] The above is only a preferred embodiment of the present invention, and the present invention is not limited to the above embodiments. It is understood that other improvements and changes directly derived or associated by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included in the protection scope of the present invention.
