Description

Technical Field

[0001] This invention relates to the field of household paper technology, specifically to a soft cream paper and its preparation method. Background Technology

[0002] With the upgrading of consumption, cream-filled tissues, which combine cleansing and skincare functions, are gradually becoming a necessity for certain groups. In existing technologies, cream-filled tissues are usually made by coating the surface of a base paper with a cream composition containing moisturizing and softening ingredients to reduce the coefficient of friction and improve skin-friendliness. However, there are still many technical defects that make it difficult to meet the needs of high-end users.

[0003] First, the formulations lack safety. Some products use benzyl ammonium salt antibacterial agents or organosilicon and quaternary ammonium salt softeners, posing a risk of irritation to sensitive skin. While adding silicone oil can improve slipperiness, it can easily cause problems such as artificial slipperiness, shine, and chemical residue. Second, the cream coating has poor uniformity and stability. Traditional spraying or sprinkling processes result in large and unevenly distributed cream droplets, easily leading to oil drift and separation. Furthermore, the cream only adheres to the base paper surface, with weak bonding to the fibers, making it prone to detachment during use. Increased viscosity at low temperatures further affects the coating effect. Third, the base paper has poor compatibility. It often uses single fibers or conventional pulping processes, resulting in a dense and rigid structure with low cream load-bearing capacity. After drying, it is prone to brittleness and breakage, and lacks synergy with the cream, resulting in limited reduction in the coefficient of friction and difficulty in effectively protecting sensitive skin. Finally, the functions are limited and the environmental adaptability is weak. Most products only focus on moisturizing or softening, lacking barrier repair and long-lasting water-locking capabilities, which can still lead to rapid moisture loss from the skin in low-humidity environments. In addition, some materials are non-biodegradable, posing environmental risks. Based on the above statements, the present invention provides a skin-softening cream paper and a method for preparing the same. Summary of the Invention

[0004] In order to overcome the shortcomings of existing skin-softening cream paper, such as strong formulation irritation, poor coating uniformity and stability, low cream load, single function and weak environmental adaptability, this invention provides a skin-softening cream paper and its preparation method.

[0005] In a first aspect, the present invention provides a skin-softening cream paper, which adopts the following technical solution: A skin-softening cream paper includes a base paper and a skin-softening cream composition loaded on the base paper; The base paper comprises the following raw materials in parts by weight: 4-6 parts softwood pulp, 2.5-3.5 parts cotton pulp, 1-2 parts bamboo pulp, and 0.4-0.6 parts alkali-modified konjac fiber; The skin-softening cream composition comprises the following raw materials in parts by weight: 3-5 parts of plant-based moisturizer, 1.2-2 parts of compound softener, 0.8-1.5 parts of natural repair factor, 1-2 parts of microecological regulation system, 0.6-1.2 parts of stress stabilizer, 0.3-0.6 parts of solubilizer, 1-3 parts of plant antibacterial agent, and 80-90 parts of deionized water.

[0006] Preferably, the preparation method of the alkalized modified konjac fiber is as follows: konjac fiber is placed in sodium hydroxide solution, soaked at room temperature, washed with deionized water until neutral, dried, and pulverized to obtain alkalized modified konjac fiber.

[0007] Preferably, the specific preparation method of the alkalized modified konjac fiber is as follows: konjac fiber is placed in a sodium hydroxide solution with a mass fraction of 5-8% at a mass ratio of 1:15-20 and soaked at room temperature for 60-90 minutes. After soaking, the konjac fiber is washed with deionized water until the pH value of the washing solution is 6.8-7.2. Subsequently, the washed konjac fiber is placed in an oven at 40-45℃ and dried until the moisture content is 10-12%. Finally, the dried konjac fiber is pulverized to a fiber length of 0.5-1 mm to obtain alkalized modified konjac fiber.

[0008] The working principle of the above-mentioned alkalized modified konjac fiber is as follows: The surface of konjac fiber is rich in hydroxyl groups. After alkalization treatment with sodium hydroxide solution, some glycosidic bonds and hydrogen bonds inside the fiber can be destroyed, making the fiber structure loose and porous, while increasing the number of surface active groups. On the one hand, it improves the adsorption capacity and binding force of the base paper to the skin cream composition, preventing the cream from falling off during use. On the other hand, it enhances the interweaving strength between the base paper fibers, improves the breaking toughness and resistance to extreme environments of the finished paper, and the modified fiber has excellent biocompatibility, is biodegradable, and has no environmental hazards.

[0009] Preferably, the plant-based moisturizer is composed of trehalose, glycerin and oat beta-glucan in a mass ratio of 2:1:0.4-0.6.

[0010] The working principle of the above-mentioned plant-based moisturizer is as follows: Trehalose, glycerin, and oat beta-glucan form a synergistic moisturizing system. Glycerin, as a small molecule moisturizer, can quickly penetrate into the stratum corneum of the skin, absorb moisture from the environment, and lock in the skin's own moisture. Trehalose is a natural non-reducing sugar that can form a breathable protective film on the skin surface, reducing moisture evaporation and alleviating damage to the skin from external stimuli. Oat beta-glucan has a suitable molecular weight and can form a breathable moisturizing film on the skin surface, firmly locking in the moisture of the stratum corneum. At the same time, its natural active groups can exert anti-inflammatory and soothing effects, reducing skin sensitivity and discomfort. The three work together to achieve a triple moisturizing effect of "rapid hydration - long-lasting moisture retention - soothing protection".

[0011] Preferably, the composite softener is composed of hydrolyzed wheat protein and hydroxyethyl cellulose in a mass ratio of 2.8-3.2:1.

[0012] The working principle of the aforementioned composite softener is as follows: Hydrolyzed wheat protein is rich in amino acid groups, has extremely strong skin affinity, and can form hydrogen bonds with the stratum corneum of the skin. This reduces the coefficient of friction between the base paper and the skin, resulting in a delicate and soft touch. It also forms a thin protective film on the skin surface, enhancing the durability of the softening effect. Hydroxyethyl cellulose, as a high-molecular-weight hydrophilic colloid, is rich in hydroxyl and ether bonds in its molecular chain, exhibiting excellent hydration and film-forming capabilities. Its long-chain polymer structure can rapidly extend in water to form a continuous and stable three-dimensional network structure. On one hand, it can act as a microscaffold, uniformly carrying and fixing active ingredients such as hydrolyzed wheat protein, ensuring stable and uniform loading on the base paper during spraying and drying. On the other hand, after water evaporation, it can form a flexible, breathable, and transparent physical protective film in situ on the skin and paper surfaces.

[0013] Preferably, the natural repair factor is composed of silk extract and calendula extract in a mass ratio of 1:1-1.5.

[0014] The mechanism of action of the above-mentioned natural repair factors is as follows: the silk fibroin in silk extract is similar in structure to the stratum corneum of the skin, can be quickly absorbed by the skin, replenish the amino acids needed by the skin, repair the damaged skin barrier, and enhance the skin's resistance; the flavonoids and saponins in calendula extract have significant anti-inflammatory and soothing effects, which can relieve skin redness, itching and other discomforts. The two work together to repair the damaged skin barrier and prevent damage to the skin from external stimuli, making it especially suitable for people with sensitive skin such as those with atopic dermatitis.

[0015] Preferably, the microecological regulation system is composed of Lactobacillus plantarum fermentation products and inulin in a mass ratio of 2-4:1.

[0016] Preferably, the method for preparing the fermentation product of *Lactobacillus plantarum* is as follows: A1. Take fresh apples and pears, crush them, mix them, add glucose and yeast extract, adjust the pH, sterilize, cool, and obtain the fermentation substrate; A2. Inoculate Lactobacillus plantarum into the fermentation substrate and ferment at a constant temperature to obtain the fermentation product; A3. After coarsely filtering the fermentation product, centrifuge it, collect the supernatant, and then perform sterile filtration and vacuum concentration to obtain the fermentation product of Lactobacillus plantarum.

[0017] Preferably, step A1 specifically includes: taking fresh apples and pears, crushing and mixing them at a mass ratio of 1-1.2:1 to obtain a mixed fruit puree, adding 2-3% glucose and 0.4-0.6% yeast extract of the mixed fruit puree by mass, adjusting the pH to 6.2-6.5 with a 4-6% citric acid solution by mass, sterilizing at 115℃ for 20 minutes, and cooling to 37℃ to obtain the fermentation substrate; Preferably, step A2 specifically includes: preparing a live bacteria count of 1.0 × 10⁻⁶. 7 -1.0×10 9 Inoculate the fermentation substrate with CFU / mL of Lactobacillus plantarum at an inoculum amount of 3-5% of the substrate mass. Ferment at 37-39℃ and 120-180rpm in an anaerobic environment for 18-24h to obtain the fermentation product. Preferably, step A3 specifically includes: coarsely filtering the fermentation product through a 200-250 mesh filter to remove impurities, then centrifuging it at 4-6℃ and 8000-10000rpm for 20-25min, and collecting the supernatant; subsequently aseptically filtering it through a 0.22μm filter membrane to remove residual bacteria, and finally concentrating it under vacuum at 35-45℃ and -0.095Mpa to -0.085Mpa until the solid content is 15-20%, to obtain the Lactobacillus plantarum fermentation product.

[0018] The mechanism of action of the above-mentioned microecological regulation system is as follows: the active ingredients such as lactic acid and antimicrobial peptides in the fermentation products of Lactobacillus plantarum can inhibit the proliferation of harmful bacteria such as Staphylococcus aureus and Propionibacterium acnes on the skin surface, and reduce the irritation of the skin by the metabolites of harmful bacteria; inulin, as a natural prebiotic, is not absorbed by the skin, and can specifically promote the proliferation of beneficial bacteria such as lactic acid bacteria and bifidobacteria on the skin surface, increase the proportion of beneficial bacteria, and build a healthy skin microecological barrier; the two work together to achieve the effect of "inhibiting harmful bacteria-promoting beneficial bacteria-maintaining the balance of the flora", which improves skin sensitivity and inflammation problems from the root and avoids the defects of existing products that only have simple antibacterial properties and destroy the skin microecology.

[0019] Preferably, the stress stabilizer is composed of vitamin E acetate and phytosterols in a mass ratio of 1:1-1.6; the solubilizer is polyglycerol fatty acid ester; and the plant antibacterial agent is composed of tea polyphenols and honeysuckle extract in a mass ratio of 2-3:1.

[0020] The mechanism of action of the above-mentioned stress stabilizers is as follows: Vitamin E acetate is a fat-soluble antioxidant that can effectively remove free radicals in the cream composition, inhibit the oxidation and rancidity of oil components, and extend the shelf life of the product; Phytosterols have the function of regulating the viscosity of oils. At low temperatures, they can reduce the crystallization rate of the cream and prevent the cream from solidifying. At high temperatures, they can enhance the stability of the cream system and prevent oil separation. The synergy of the two makes the product adaptable to extreme temperature and extreme humidity environments, breaking through the limitations of existing product scenarios.

[0021] Secondly, the present invention provides a method for preparing a skin-softening cream paper, which adopts the following technical solution: A method for preparing a skin-softening cream paper includes the following steps: S1. Heat deionized water, add plant-based moisturizer and cosolvent, and stir to obtain mixture A; heat up, add compound softener and stress stabilizer, and ultrasonically emulsify and stir to obtain mixture B; cool down, add microecological regulation system, natural repair factor and plant antibacterial agent, stir, homogenize under high pressure, and cool to room temperature to obtain skin-softening cream composition. S2. After crushing the softwood pulp, cotton pulp, and bamboo pulp separately, mix them together, add alkali-modified konjac fiber, mix, beat, shape, wrinkle, and dry to obtain the base paper; S3. Spray the skin-softening cream composition onto both sides of the base paper and dry to obtain skin-softening cream paper.

[0022] Preferably, step S1 specifically includes: heating deionized water to 50-55°C, adding plant-based moisturizer and polyglycerol fatty acid ester, stirring at 500-600 rpm for 30-40 min to obtain mixture A; heating mixture A to 65-70°C, adding composite softener and stress stabilizer, and ultrasonically emulsifying and stirring at 40-45 kHz at 800-1000 rpm for 40-50 min to obtain mixture B; cooling mixture B to 40-45°C, adding microecological regulation system, natural repair factor and plant antibacterial agent, stirring at 200-300 rpm for 10-20 min, then homogenizing under high pressure of 25-30 MPa 2-4 times, 6-10 min each time, and cooling to room temperature to obtain a skin-softening cream composition.

[0023] Preferably, step S2 specifically includes: breaking down softwood pulp, cotton pulp, and bamboo pulp to a degree of non-dispersibility ≥98%, mixing and stirring at 100-200 rpm for 10-15 min, adding alkali-modified konjac fiber, mixing and stirring at 100-200 rpm for 10-15 min; beating the pulp, controlling the overall freeness to 25-28°SR, and adjusting the pulp concentration to 3-5%; forming the pulp on a wire paper machine without doctor blade wrinkling, with a wrinkling rate of 16-19%, and drying it at 60-65℃ to a moisture content of 8-10% to obtain the base paper.

[0024] Preferably, step S3 specifically includes: using a double-sided precision spraying process, uniformly spraying the skin-softening cream composition onto both sides of the base paper, with a spraying pressure of 0.3-0.5MPa and a total spraying amount of 20-25g / m², and sending the sprayed paper into a constant temperature and humidity drying oven to dry it to a moisture content of 6-8% under conditions of 55-60℃ and 40-45% humidity, to obtain skin-softening cream paper.

[0025] Thirdly, the present invention provides an application of the above-mentioned soft cream paper in the care of people with fragile skin or sensitive skin.

[0026] In summary, the present invention has the following beneficial effects: 1. The cream composition of this invention abandons irritating ingredients such as synthetic organosilicon and quaternary ammonium salts, and is formulated with all-natural plant-based raw materials. Plant-based moisturizers, compound emollients, natural repair factors and plant antibacterial agents work synergistically, without any slippery feeling or risk of chemical residue. The product's pH value is stable in the slightly acidic range, which is consistent with the healthy skin's lipid film environment.

[0027] 2. This invention introduces a microecological regulation system of "Lactobacillus plantarum fermentation products + inulin" into the cream formula. Through probiotic metabolites (lactic acid, antimicrobial peptides), it inhibits the proliferation of harmful bacteria on the skin, while prebiotic inulin specifically promotes the growth of beneficial bacteria, thereby increasing the proportion of beneficial bacteria in the skin and building a stable skin microecological barrier. Compared to existing products that only have single antibacterial or moisturizing functions, this invention fundamentally improves skin sensitivity and inflammation, reducing the probability of recurring redness.

[0028] 3. Alkali-modified konjac fiber is added to the base paper. After alkalization treatment, the fiber structure becomes loose and porous, which not only increases the base paper's adsorption capacity for the cream composition and enhances the binding force between the cream and the fiber, preventing the cream from falling off during use, but also improves the interweaving strength of the base paper fibers, making it less prone to damage in both dry and wet conditions. Combined with the skin-friendly and lubricating effect of the composite softener, the base paper has a low coefficient of friction and a feel close to silk, significantly reducing frictional damage to the skin during wiping.

[0029] 4. Synergistic effect of stress stabilizers: Vitamin E acetate effectively inhibits the oxidation and rancidity of cream oils, extending product shelf life; phytosterols regulate cream viscosity, enabling stable storage in extreme temperature and humidity environments without low-temperature solidification or high-temperature stratification. Suitable for various scenarios such as frequent wiping by rhinitis patients, dry winters in the north, and humid summers in the south, achieving "stable function in all scenarios".

[0030] 5. This invention integrates multiple functions such as moisturizing and water-locking, skin softening and lubrication, microecological regulation, anti-inflammatory and soothing, and antibacterial protection. It can meet the needs of various scenarios such as daily care for fragile skin, skin cleaning for infants and young children, high-frequency wiping for rhinitis patients, and postoperative skin sensitivity protection. Compared with traditional single-function cream paper, it has a wider range of applications and higher use value. Detailed Implementation

[0098] Performance verification The performance of the skin-softening cream paper prepared in Examples 1-3 and Comparative Examples 1-4 was then tested.

[0099] Cream loading (g / m²): Take a piece of base paper from the same batch that has not been coated with the skin-softening cream composition, cut it into 10cm×10cm pieces, and accurately weigh it, recording it as W0. Take another piece of finished skin-softening cream paper after coating, immediately cut it into the same size, and accurately weigh it, recording it as W1. Calculate the wet weight loading of the cream using the following formula: Cream loading (g / m²) = (W1–W0) / 0.01 (Note: 0.01 is the sample area, unit: m²); Cream shedding rate (%): Take another batch of soft cream paper from the same batch as the cream load test and cut it into 10cm×10cm samples. Fix the sample directly onto the stage of the friction tester (without drying treatment to simulate use). Apply a 50g vertical load to the sample surface and drive the sample to rub continuously on the standard silicone friction plate 10 times at a frequency of 1 reciprocating stroke per second. Collect all the shed material generated during the rubbing process. Transfer all the collected shed material to a pre-weighed weighing container, place it in a 105℃ oven to dry to constant weight, cool it, and weigh it. Record the obtained mass as follows. To calculate the denominator of the shedding rate (the total dry weight of the cream on the sample), a parallel drying experiment is required. Take blank base paper (without cream composition) and finished soft cream paper from the same batch, and cut them into 10cm × 10cm pieces respectively. Place both in a 60℃ vacuum drying oven and dry to constant weight. After cooling, weigh them separately, and record the resulting mass as: dry weight of blank base paper. Dry weight of finished cream paper The total dry weight of the cream loaded on the sample is then... .

[0100] Calculation: Cream shedding rate is calculated using the following formula: Cream shedding rate (%) = ; Coefficient of friction (μ): The dynamic coefficient of friction between the sample and the artificial skin membrane was measured using a coefficient of friction meter (KES-SE). Five samples were measured in each group and the average value was taken. The lower the value, the smoother the skin feel. Transepidermal water loss (TEWL, g / m²·h): To assess the immediate impact of skin-softening cream sheets on the barrier function of sensitive skin, a standardized human patch test was used to determine transepidermal water loss. Thirty selected volunteers with sensitive skin were recruited. After acclimatizing for 30 minutes in a constant temperature and humidity environment, a uniform test area was marked on the inner forearm. The baseline TEWL value (T0) before wiping was measured using a Tewameter® TM300 transepidermal water loss meter. Subsequently, the same operator gently wiped the test area three times in the same direction with normal application pressure. Two hours after wiping, the TEWL value was measured again at the original test site and recorded as T. 120 , with T 120 As an evaluation indicator: the lower the value, the less the product disturbs the skin barrier, and the better the moisturizing effect and gentleness.

[0101] All samples were equilibrated for 24 hours at 25℃ and 50% relative humidity before being tested uniformly. The test results are shown in Table 1.

[0102] Table 1 Performance Verification Results The soft cream paper prepared in Examples 1-3 of this invention exhibits excellent and balanced comprehensive performance in terms of cream loading, adhesion, skin-friendly smoothness, and skin barrier friendliness. Test results show that the products in these examples successfully achieve a balance between high loading capacity and low shedding, significantly reducing friction with the skin during use and minimizing immediate impact on the skin barrier of sensitive skin.

[0103] Comparative Example 1: The cream loading was significantly lower than that of the Example, and the shedding rate increased sharply, along with the coefficient of friction. This directly demonstrates the key role of alkali-modified konjac fiber in improving the adsorption capacity of the base paper, enhancing the cream adhesion, and improving the overall smoothness of the paper.

[0104] Comparative Example 2: Although its performance was better than Comparative Example 1, it was still significantly inferior to the Example. This result further confirms that alkalization modification of konjac fiber can effectively activate the fiber surface and improve its binding performance with cream components.

[0105] Comparative Example 3: The cream loading was similar to that of the Example, but the shedding rate was higher and the TEWL value was significantly increased, indicating that the product's barrier protection effect on sensitive skin was significantly weakened after the absence of Lactobacillus plantarum fermentation products and inulin.

[0106] Comparative Example 4: Its performance falls between that of Example 1 and Comparative Example 3, especially its TEWL value, which is better than Comparative Example 3 but not as good as Example 1. This indicates that the complex active ingredients (such as antimicrobial peptides and metabolites) in the fermentation products of *Lactobacillus plantarum* can more effectively help maintain skin barrier homeostasis and reduce moisture loss compared to lactic acid alone. This specific embodiment is merely an explanation of the present invention and is not intended to limit it. Those skilled in the art can make modifications to this embodiment without contributing any inventive step after reading this specification, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present invention.
