Description

Technical Field

[0001] This invention belongs to the field of cream paper technology, specifically relating to a cream for cream paper and its preparation method, and a cream paper for colds and its preparation method. Background Technology

[0002] During a cold, patients often need to frequently wipe around their nose and expel secretions. The surface of ordinary household paper fibers is relatively rough, the texture is relatively hard, and the coefficient of friction is relatively high. Continuous wiping inevitably leads to redness and stinging of the skin around the nose. In severe cases, it can even cause damage to the skin barrier, such as dryness, cracking, and peeling, increasing the patient's pain and inconvenience.

[0003] Cream-textured tissues are ultra-soft tissues with added moisturizing cream ingredients, offering a slightly improved feel compared to regular tissues. Their softness can partially reduce discomfort from frequent wiping. However, existing cream-textured tissue products and processing technologies cannot completely solve the aforementioned problems and generally suffer from the following shortcomings: Most existing cream-textured tissues only focus on basic moisturizing functions, lacking overall efficacy design for scenarios like colds and runny noses; they can only passively reduce skin damage from frequent wiping through their softness, and in ultra-high-frequency usage scenarios (such as severe colds or severe rhinitis), skin damage is still unavoidable. Therefore, existing products are not yet fully suitable for high-frequency wiping scenarios such as colds, runny noses, and rhinitis.

[0004] With the upgrading of consumption, the development of a cream paper specifically designed for high-frequency nasal wiping scenarios, which provides a cool touch and fresh scent while being soft, has significant application value and market prospects. Summary of the Invention

[0005] The purpose of this invention is to provide a cream for use in tissue paper, which can minimize discomfort such as redness around the nose caused by frequent wiping in situations such as colds.

[0006] A second objective of this invention is to provide a method for preparing the above-mentioned cream for cream paper.

[0007] A third objective of this invention is to provide a cold cream paper using the aforementioned cream.

[0008] The fourth objective of this invention is to provide a method for preparing the above-mentioned cold cream paper.

[0009] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0010] A cream for paper, comprising the following components in parts by weight, based on a total weight of 100 parts: 60-85 parts glycerin, 10-25 parts water, 0.5-2 parts polydimethylsiloxane, 3-8 parts diol, 1-5 parts squalane, 0.1-1 parts eucalyptus oil, 0.05-0.5 parts menthol, 0.5-2 parts panthenol, 0.1-0.5 parts dipotassium glycyrrhizate, 0.1-0.5 parts allantoin, and 0.5-2 parts emulsifier.

[0011] The diol is any one or a combination of propylene glycol and butanediol.

[0012] Furthermore, the hydrophilic-lipophilic balance (HLB) of the emulsifier is 4-6.

[0013] The emulsifier is Span 60 (sorbitan monostearate) or Span 80 (sorbitan monooleate).

[0014] A method for preparing the above-mentioned cream for paper includes the following steps:

[0015] 1) Mix glycerol, diol and most of the water, heat to 80-85℃, and stir until completely mixed to obtain a mixed solution;

[0016] Dissolve allantoin in a small amount of water at 75-85℃ to obtain an allantoin solution;

[0017] 2) Mix polydimethylsiloxane, squalane, eucalyptus oil, menthol, and emulsifier, heat to 60-70℃, stir until homogeneous, add to the mixed solution obtained in step 1), keep warm and stir until homogeneous to obtain the mixture;

[0018] 3) Add panthenol, dipotassium glycyrrhizate and the allantoin solution obtained in step 1) to the mixture obtained in step 2) in sequence, and stir until the mixture is homogeneous.

[0019] Furthermore, the "small portion" of water mentioned in step 1) refers to 1 / 25 to 1 / 10 of the total water mass. In contrast, the "remaining portion" refers to the majority of the water.

[0020] Furthermore, in step 2), the temperature of the heat preservation and stirring is 60-70℃.

[0021] A cold cream paper using the above-mentioned cream.

[0022] A method for preparing the above-mentioned cold cream paper includes the following steps:

[0023] The cream is heated to 35-45℃ and coated onto a single layer of base paper at a coating weight of 20%-60% of the base paper weight to obtain a single-layer cream paper. Two to six layers of single-layer cream paper are then laminated together, rolled up, wrapped with stretch film, and cured for 24-48 hours to obtain the final product.

[0024] The basis weight of the single-layer base paper is 10-16 g / m². 2 .

[0025] Furthermore, the coating is applied using a roller coating method. More preferably, multiple sets of coating rollers are used, employing a layered coating method.

[0026] More preferably, the coating refers to coating both sides of a single-layer base paper.

[0027] The method for preparing the base paper includes the following steps:

[0028] a) Pulping: Pulping enzyme is mixed with long-fiber softwood pulp, and after enzymatic hydrolysis and pulping, a long-fiber beaten pulp with a beating degree of 24-34°SR is obtained; pulping enzyme is mixed with short-fiber hardwood pulp, and after enzymatic hydrolysis and pulping, a short-fiber beaten pulp with a beating degree of 20-30°SR is obtained; the obtained long-fiber beaten pulp and short-fiber beaten pulp are mixed, a softener is added, and after refining, a pulp with a beating degree of 25-35°SR is obtained;

[0029] b) Softening: Add a wet strength agent to the obtained pulp and disperse it evenly to obtain softened pulp;

[0030] c) Papermaking: The obtained softened pulp is then papermade to obtain the final product.

[0031] Based on the oven-dry weight of the pulp, the base paper is mainly made from the following raw materials in parts by weight: 20-30 parts long-fiber softwood pulp, 70-80 parts short-fiber hardwood pulp, and 0.3-0.8 parts softener; based on the weight of the finished base paper, the amount of pulping enzyme is 0.05-0.1 kg / ton of paper; and the amount of wet strength agent is 20-25 kg / ton of paper.

[0032] Furthermore, the softener is a cationic softener.

[0033] The wet strength agent is a PEA wet strength agent.

[0034] Furthermore, in step a), the enzymatic hydrolysis time is 45-90 min.

[0035] Furthermore, in step a), a disc mill is used for pulping. More preferably, the pulping power for long-fiber softwood pulp is 35-80 kWh / t; and the pulping power for short-fiber hardwood pulp is 40-60 kWh / t.

[0036] Furthermore, in step a), a homogenizing mill is used for pulping. More preferably, the pulping power is 15-20 kWh / t.

[0037] In step c), the parameters for the papermaking process are: sizing concentration 3%-3.5%, sizing-to-mesh ratio 0.89-0.95, air hood temperature 140-160℃, scraper blade angle 80°-85°, and wrinkling rate 18%-24%.

[0038] Furthermore, in step c), papermaking is carried out on a high-speed crescent paper machine; a ceramic or alloy doctor blade is used.

[0039] In the cream for cream paper of the present invention, glycerin is the moisturizing component, water is the solvent, polydimethylsiloxane (silicone oil) is the smoothing component, diol is the auxiliary moisturizing component, squalane is the repairing component, eucalyptus leaf oil and menthol are the cooling components, and panthenol (provitamin B5), dipotassium glycyrrhizate and allantoin can adhere to the skin surface; the above-mentioned components work together synergistically, have good compatibility, are non-irritating, can be directly adapted to the cream paper coating process, have controllable costs, and are suitable for industrial production.

[0040] The cream used in this invention for tissue paper has a highly targeted effect: in the cream formula, eucalyptus leaf oil and menthol work synergistically to achieve a cooling sensation and refreshing scent; panthenol, dipotassium glycyrrhizate, and allantoin work synergistically to minimize redness and other phenomena caused by repeated rubbing. Tissue paper prepared using this cream is suitable for high-frequency wiping scenarios such as colds, distinguishing it from ordinary tissues or cream-filled tissues.

[0041] In the paper preparation method of this invention, the raw materials are a composite fiber blend, wherein long-fiber softwood pulp improves the toughness of the paper (preventing breakage when wiping one's nose), and short-fiber hardwood pulp improves its fineness. Long and short fibers are pulped separately, and enzymatic hydrolysis of the fibers during pulping improves fiber softness. After pulping, a cationic softener is added to prepare the pulp, further improving the inherent softness of the paper; a PAE wet strength agent is added to improve the paper's wet strength, preventing it from easily breaking when wiping one's nose.

[0042] The method for preparing the cold cream paper of the present invention involves preheating the cream to reduce its viscosity and improve the uniformity of coating and the permeability of the cream; and adopting a layered coating method to minimize the uneven distribution of cream between layers and the phenomenon of weak bonding in multi-layer composite structures.

[0043] The cold cream paper of the present invention has excellent softness: through fiber ratio optimization, fine pulping control, creping and other processes, the base paper is made soft, delicate, fluffy and tough; after adding cream, the softness is further optimized and its surface friction coefficient is reduced, so that it feels smooth and without rough foreign objects when wiping the nose, reducing damage to the skin.

[0044] This invention is highly practical: all components and processes are conventional and feasible technologies in the tissue paper industry, requiring no additional complex equipment, keeping costs under control, enabling large-scale industrial production, and providing a superior user experience with promising market application prospects.

[0045] This invention, through the synergistic design of cream formulation, base paper production process, and coating production method, produces cream paper suitable for cold and runny nose scenarios. While achieving high softness, it also has a comfortable touch and a cooling sensation, making it particularly suitable for scenarios that require frequent nasal wiping, such as colds and allergic rhinitis, and greatly avoiding discomfort symptoms such as redness around the nose caused by repeated wiping.

[0106]

[0107] Note: Red Zone The value is a core colorimetric index used in the fields of cosmetic efficacy evaluation and dermatological testing to quantify the degree of skin redness and inflammation.

[0108] As shown in Table 1, compared with the blank control area, there was a significant difference in the change of skin stratum corneum moisture content in the sample application area after 30 minutes of application. The evaluation results indicate that under the evaluation conditions, the sample has the effect of improving skin stratum corneum moisture content.

[0109] Compared to the blank control area, immediately after wiping with 40 tissues, the change in transepidermal water loss rate of the sample area was significantly reduced. The evaluation results indicate that, under these evaluation conditions, the sample did not significantly alter the transepidermal water loss rate.

[0110] Compared to the blank control area, immediately after wiping with 40 paper towels, the change in color 'a' in the red area of ​​the sample application area was significantly reduced, while the change in the percentage of red area was not significantly reduced. The evaluation results indicate that, under these evaluation conditions, the sample does not exhibit reddening upon rubbing.

[0111] Evaluation results show that the cream paper prepared using the cream of the present invention has the effect of improving the moisture content of the stratum corneum of the skin; after high-frequency wiping, it can reduce the transepidermal water loss rate of the skin, so that the skin does not turn red due to friction.

[0112] Experimental Example 2

[0113] This experimental example is a self-assessment (satisfaction) survey of the subjects after 28 days of use of the cream paper obtained in Example 1. The results are shown in Table 2. The subjects in this assessment were 33 healthy men and women.

[0114] Rating criteria: 1-5 points, where 1 point indicates strong disagreement, 2 points indicates some disagreement, 3 points indicates neither agreement nor disagreement, 4 points indicates some agreement, and 5 points indicates strong agreement. The degree of agreement is calculated as: (Number of participants with a score > 3) ÷ (Number of valid participants) × 100%.

[0115] Table 2. Results of subjects' 28-day self-assessment (satisfaction)

[0116]

[0117] The evaluation results showed that after 28 days of use, 97% of the subjects felt that the product was moisturizing and caring, and 100% of the subjects agreed that there was no irritation after use.

[0118] 100% of the test subjects felt that the product was soft and gentle on the skin after use; 97% of the test subjects felt that it could protect sensitive areas after use; 100% of the test subjects agreed that the skin did not turn red after repeated wiping; 100% of the test subjects agreed that the skin around the nose, such as the tip and wings of the nose, did not turn red after wiping; and 100% of the test subjects felt that the skin was not dry after use.

[0119] Evaluation results show that the cream paper prepared using the cream of this invention is moisturizing and gentle on the skin, soft and non-irritating, and does not cause redness or dryness when frequently wiped. It is especially gentle on sensitive areas such as the tip and wings of the nose, and has excellent effects.
