Description

Natural bamboo water tissue including less harmful chemical liquid}

The present invention relates to a natural bamboo wet tissue containing a low-hazardous chemical solution.

Wet tissue is a type of tissue paper manufactured using pulp, and is used in various fields such as skin washing, various cleaning and hygiene, cleaning, washing dishes, and makeup removal.

Wet tissue is a product in which the fabric is impregnated with a chemical solution, and since it always exists in an impregnated state, it has conditions for bacteria to easily propagate. Therefore, in addition to purified water, a preservative for suppressing bacteria is necessarily used in the chemical solution.

Synthetic preservatives are widely used as preservatives, and among them, parabens (para-oxybenzoic acid esters) are typically used. However, there are harmfulness problems such as causing allergies or skin troubles such as rashes, red spots or skin inflammation.

Accordingly, various attempts have been made to replace synthetic preservatives. For example, products using some natural extracts are being developed [Patent Documents 1 and 2], but commercialization has not yet been realized due to problems such as coloration and stability degradation of the natural extracts.

KR　10-1533195B (2015.07.02, Notice) KR 10-2013-0028196 (2013.03.19, published)

In the present invention, in order to facilitate commercialization, a chemical solution composed of only substances with low harmfulness to the human body and proven stability was constructed, and a fabric in the drug solution was impregnated to prepare a wet tissue so as to solve conventional allergy or skin trouble problems.

Accordingly, an object of the present invention is to provide a natural bamboo wet tissue containing a low-hazardous chemical solution in which bamboo fabric is immersed in a chemical solution containing only EWG (Environmental Working Group) first-class materials.

In order to achieve the above object, the present invention provides a natural bamboo wet tissue in which a natural bamboo fabric is immersed in a low-hazardous chemical solution.

The low-hazardous liquid is purified water; antiseptic; skin conditioning agents; naturally derived surfactants; moisturizers; and additives, but these compositions use only EWG Grade 1 raw materials.

Specifically, the preservatives are hydroxyacetophenone and 1,2-hexanediol, the skin conditioning agent is centella asiatica extract, the natural surfactant is coco-glucoside, the humectant is methylpropanediol, and the additive is ethylhexylglycerin and glyceryl caprylate.

The natural bamboo fabric has a moisture content of 70% by weight or more per sheet and a moisture loss rate of 5% by weight or less after 30 minutes compared to the initial moisture content.

In addition, the natural bamboo fabric has a basis weight of 30 to 80 gsm and a thickness of 0.3 to 0.8 mm.

The wet tissue according to the present invention uses 100% natural bamboo fabric as a fabric and is manufactured using only EWG grade 1 raw materials that have low harm to the human body and proven safety as a chemical solution.

The natural bamboo wet tissue has a deodorizing effect and antibacterial effect due to the characteristics of bamboo itself, and minimizes skin irritation problems such as rashes, red spots or skin inflammation that occur when using wet tissue due to the low harmfulness and high stability of the low-harmful liquid composition. can In addition, there is no change in components even after long-term storage, so it has excellent durability and can effectively prevent bacterial propagation.

The 'wet tissue' referred to in the present invention is a fabric impregnated with a chemical liquid, and includes cleaning wet wipes, facial wet wipes, bidet wet wipes, infant wipes, multi-purpose wet wipes, makeup removal wipes, feminine hygiene wipes, etc. It means disposable tissue.

In the wet tissue according to the present invention, the fabric and chemical solution are made of 'environmentally friendly' materials.

The wet tissue fabric is made of 100% natural bamboo material and does not contain other natural or synthetic fibers other than the bamboo.

Wet tissue chemicals use only EWG grade 1 raw materials. EWG (Environmental Working Group) rating evaluates the harmfulness and safety of a composition, and the smaller the number, the less harmful it is and the safer it is.

Hereinafter, the present invention will be described in detail.

The wet tissue according to the present invention is prepared by impregnating a natural bamboo wet tissue fabric with a low-hazardous chemical solution, wherein the low-hazardous chemical solution is purified water; antiseptic; skin conditioning agents; naturally derived surfactants; moisturizer; and additives, and at this time, other components except purified water are used only as EWG grade 1 raw materials.

Composition of low-toxic chemical solution

The purified water of the low-hazardous drug solution is purified water filtered through a filtration device of 2 to 8 stages. The filtration device is one in which processes such as microfiltration, reverse osmosis filtration, activated carbon filtration, and ultraviolet sterilization are connected in series in various combinations, and are safe from bacteria or germs and are free of substances harmful to the human body.

As preservatives, Hydroxyacetophenone and 1,2-Hexanediol are used together. The hydroxyacetphenone and 1,2-hexanediol are EWG grade 1 substances as preservatives that can replace conventional parabens.

Hydroxyacetphenone has an excellent preservative effect and excellent stability at all temperatures and pH. In addition, 1,2-hexanediol has an excellent antiseptic effect with a small amount of use, excellent moisturizing and antibacterial properties, and excellent miscibility with other compositions because it has a structure of a surfactant. However, if it is added excessively, the viscosity of the chemical solution is greatly reduced, and the content needs to be adjusted.

In the present invention, hydroxyacetophenone and 1,2-hexanediol are mixed and used, and have synergistic preservative and antibacterial power compared to the case of using them alone, and have significantly better preservative power and lower skin irritation than conventional paraben preservatives. . Specifically, hydroxyacetophenone and 1,2-hexanediol may be included in a weight ratio of 1:10 to 10:1, preferably 1:1 to 5:1, more preferably 1:1 to 3 : 1 weight ratio.

The preservative of the combination of hydroxyacetophenone and 1,2-hexanediol is used in an amount of 0.1 to 10 parts by weight and 1 to 5 parts by weight based on 100 parts by weight of purified water. If the content is less than the above range, it is not possible to achieve a preservative power sufficient to replace conventional chemical preservatives (ie, parabens), and even if it exceeds the above range, the degree of improvement in effect is insignificant, which is uneconomical.

The skin conditioning agent may be Centella Asiatica Extract, which is an EWG grade 1 substance. The centella asiatica extract contains madecassoside and asiaticoside as active ingredients as saponins, and asiatic acid and madecassic acid as triterpenes. It contains 　regeneration, 　antibacterial, 　anti-inflammation, 　antioxidation, and 　skin tone 　improving effect. The centella asiatica extract refers to an extract obtained by extracting the stem, leaves, roots, etc. of centella asiatica with water and/or an organic solvent (ethanol, methanol) as an extraction solvent. The meaning of the extract includes a concentrated liquid extract or solid extract from which the extraction solvent is removed by freeze drying, vacuum drying, hot air drying, spray drying, or the like.

The Centella Asiatica extract is preferably used in an amount of 0.01 to 10 parts by weight or 0.1 to 3 parts by weight based on 100 parts by weight of purified water. If it is less than the above range, the skin conditioning effect cannot be obtained, and on the contrary, if it exceeds the above range, there is a risk of causing skin trouble.

Surfactants may be naturally derived surfactants, and known surfactants may be used except for those prohibited because they are harmful to the human body. Preferably, the naturally derived surfactant includes decyl glucoside, coco-glucoside, lauryl glucoside, apple wash, and the like, and in the present invention Coco-glucoside, an EWG grade 1 substance, is used. The coco-glucoside is a condensation reaction product of coconut alcohol and glucose, and is derived from corn, coconut, and palm kernel oil, and can be used for sensitive and delicate skin.

The naturally derived surfactant is preferably used in an amount of 0.01 to 10 parts by weight and 0.5 to 5 parts by weight based on 100 parts by weight of purified water. If it is less than the above range, the mixing of the liquid composition may not be performed smoothly, and if it exceeds the above range, it may rather cause skin trouble or be uneconomical.

The humectant adds and maintains moisture, and may include methyl propanediol, pentylene glycol, caprylyl glycol, and the like. In the present invention, methyl propanediol, an EWG grade 1 substance, is used.

The moisturizing agent is preferably used in an amount of 0.01 to 10 parts by weight or 1 to 8 parts by weight based on 100 parts by weight of purified water. If it is less than the above range, the moisturizing effect cannot be obtained, and on the contrary, if it exceeds the above range, the stability of the liquid composition may be reduced due to an increase in viscosity.

In addition to the above composition, commonly used additives may be further included.

Additives that can be used may include pH adjusters, denaturants, corrosion inhibitors, metal ion sequestering agents, sweeteners, antistatic agents, preservatives, solubilizers, antibacterial agents, deodorants, fragrances, and the like. In the present invention, ethylhexylglycerin and glyceryl caprylate, which are EWG grade 1 substances, are used as additives to support the preservative effect along with the skin conditioning effect.

Ethylhexylglycerin is a vegetable glycerin of natural origin and has a high moisturizing power, and is used as the skin conditioning agent and preservative adjuvant. Such glyceryl caprylate is preferably used in an amount of 0.01 to 5 parts by weight or 0.1 to 1 part by weight based on 100 parts by weight of purified water. If it is less than the above range, the above effects cannot be obtained, and conversely, if it exceeds the above range, the stability of the liquid composition may deteriorate due to an increase in viscosity.

Glyceryl caprylate is an auxiliary emulsifier and is known as a natural preservative because of its strong antibacterial activity. The glyceryl caprylate is preferably used in an amount of 0.01 to 5 parts by weight or 0.1 to 1 part by weight based on 100 parts by weight of purified water. If it is less than the above range, the above effect cannot be obtained, and conversely, if it exceeds the above range, there is no significant improvement in effect and it is uneconomical.

According to one embodiment of the present invention, the low-hazard liquid composition is purified water; antiseptic; skin conditioning agents; naturally derived surfactants; moisturizers; and additives, but each composition uses only EWG grade 1 materials.

Specifically, in the low-hazardous liquid composition, the preservatives are hydroxyacetophenone and 1,2-hexanediol, the skin conditioning agent is centella asiatica extract, the natural surfactant is coco-glucoside, the humectant is methylpropanediol, The additives are ethylhexylglycerin and glyceryl caprylate.

More specifically, the low-hazardous liquid composition of the present invention contains 0.1 to 10 parts by weight of hydroxyacetophenone and 1,2-hexanediol, 0.01 to 10 parts by weight of centella asiatica extract, and 0.01 to 10 parts by weight of coco-glucoside, based on 100 parts by weight of purified water. parts by weight, 0.01 to 10 parts by weight of methylpropanediol, 0.01 to 5 parts by weight of ethylhexylglycerin, and 0.01 to 5 parts by weight of glyceryl caprylate.

bamboo fabric

Meanwhile, the bamboo wet tissue according to the present invention uses a fabric made of 100% natural bamboo.

Natural bamboo fabric is a pure vegetable natural fiber material, also called breathing fiber, and is a natural cellulose-based fiber extracted from pure bamboo pulp.

The basis weight of the natural bamboo fabric is 30 to 80 gsm and 35 to 75 gsm, and it has a good feeling of use due to an appropriate thickness during use, and can maintain a certain strength even when absorbing contaminants such as water or oil. In addition, the thickness is 0.3 to 0.8 mm and 0.35 to 0.75 mm. The thickness of this natural bamboo fabric can be made thicker or thinner than the above range depending on the purpose, and if necessary, can be made in the form of two or more layers.

The natural bamboo fabric according to the present invention having these basic specifications has physical properties such as moisture content, moisture holding capacity, strength, and elongation that wet tissues should have through limiting parameters in dry and wet states.

Moisture content refers to the moisture content when a sample achieves moisture equilibrium from a low moisture content in a standard state.

The moisture content is calculated as shown in Equation 1 below, when the weight of the sample in the wet state is a and the weight of the sample after drying is b.

[Equation 1]

Water content (%) = (a-b) ÷ a × 100

At this time, the sample has a size of 19.2 cm * 19.2 cm * 0.51 mm (width * length * thickness), is a sheet of bamboo fabric with a basis weight of 65 gsm, and the moisture content is an average value using 50 samples.

The sample weight a in the wet state is a value measured after moisture equilibration by impregnating one bamboo fabric with distilled water for 24 hours to absorb moisture naturally. In order to achieve the moisture balance, the bamboo fabric before impregnation is left for 24 hours at a drying oven temperature of 100 ° C. to completely remove moisture before use.

The sample weight b in the dry state is a value measured after completely removing moisture by leaving the bamboo fabric at a drying oven temperature of 100 ° C. for 24 hours.

The natural bamboo fabric according to the present invention has a moisture content in the range of 70 to 85% by weight and 71 to 84% by weight, measured according to Equation 1 above. The range of the moisture content is a value capable of compensating for unwanted natural evaporation during use or storage. In addition, when the moisture content is low or excessive, it is preferable to have the above range because it causes discomfort during use.

A wet tissue having such a range of moisture content must maintain a sufficient level of moisture during use, especially within 30 minutes, considering the use time of the wet tissue, as the evaporation of moisture is minimized even during use. The water retention can be referred to as water retention, and can be confirmed by measuring the change in water content within 30 minutes, that is, the water evaporation rate.

The moisture evaporation rate is measured based on the wet state, and specifically, if the sample weight in the wet state is a' and the sample weight after 30 minutes is b', the moisture evaporation rate after 30 minutes is calculated as shown in Equation 2 below.

[Equation 2]

Moisture evaporation rate after 30 minutes (%) = (a'-b') ÷ a' × 100

At this time, the sample has a size of 19.2 cm * 19.2 cm * 0.51 mm (width * length * thickness), is a sheet of bamboo fabric with a basis weight of 65 gsm, and the moisture evaporation rate is an average value using 50 samples.

The wet sample weight a' is a value measured after moisture equilibration by impregnating one sheet of bamboo fabric in distilled water for 24 hours to naturally absorb moisture. In order to achieve the moisture balance, the bamboo fabric before impregnation is left for 24 hours at a drying oven temperature of 100 ° C. to completely remove moisture before use.

The sample weight b' after 30 minutes is the value of the bamboo fabric measured after leaving the wet sample at 25°C and 40% relative humidity for 30 minutes.

The bamboo fabric according to the present invention has a moisture evaporation rate of 5% by weight or less and 4.5% by weight or less, measured according to Equation 2 above. The moisture evaporation rate after 30 minutes of wet tissue is related to the function and economic problems of the wet tissue. The eco-friendly natural bamboo wet tissue according to the present invention minimizes volatilization of moisture within the time of use, and has a low moisture evaporation rate of 5% by weight or less after 30 minutes, so that it can maintain a wet state with a high moisture content during use.

On the other hand, the use of the wet tissue is performed in a repetitive up-down or left-right motion, and frictional force is generated by this motion, and accordingly, the surface of the wet tissue is worn or peeling occurs, and in severe cases, it is torn. In order to prevent this, the wet tissue must have tensile strength and elongation in dry and wet conditions above a certain level.

Dry tensile strength, wet tensile strength, dry elongation and wet elongation are measured according to KS K 0521: 2017, the strip method. At this time, the sample is made in a rectangular shape of 5 cm * 15 cm, and the gripping distance is set to 100 mm in a constant speed tensile tester. After confirming the elongation at break by performing three preliminary experiments, a final test was performed by setting the gripping distance and tensile speed. The test was tensile in the longitudinal and transverse directions, respectively, and 5 sets of samples were prepared for each direction and measured 5 times each, and the average of the measured values was taken as the tensile strength (N) and elongation (%) in each direction.

Dry tensile strength and dry elongation were measured after leaving the sample at a drying oven temperature of 100 ° C. for 24 hours to completely remove moisture in the sample, and wet tensile strength and wet elongation were measured by immersing the sample in distilled water for 24 hours after the dry state. It is measured after moisture equilibration by absorbing moisture.

The dry tensile strength of the bamboo fabric according to the present invention is 30 to 50 N/5cm and 32 to 48 N/5cm in the longitudinal direction, and the dry tensile strength in the transverse direction is 15 to 30 N/5cm and 15 to 28 N/5cm. Further, the wet tensile strength in the machine direction is 8 to 15 N/5 cm and 9 to 14 N/5 cm, and the wet tensile strength in the transverse direction is 4 to 10 N/5 cm and 4.5 to 9.5 N/5 cm.

When it has dry and wet tensile strength in the above range, the usability of the wet tissue is excellent and there is no tearing during use. At this time, if the wet tensile strength in the transverse direction is high, there is a feeling that the wet tissue itself is watery, and damage is prevented during use when the wet tensile strength in the transverse direction is high.

In addition, damage such as wipeability and tearing of wet wipes is related to wet tensile strength and dry tensile strength. Specifically, the ratio of machine direction dry tensile strength / transverse direction dry tensile strength is preferably 1.5 to 3, 1.8 to 2.5, and the difference between the dry tensile strength in the transverse direction and the wet tensile strength in the transverse direction is 20 N / 5 cm or less, 18 It is preferable that it is N/5cm or less. When these ranges are satisfied, a balance between softness and durability of the aforementioned wet wipes can be maintained.

In addition, in the case of elongation, the drying elongation of the bamboo fabric according to the present invention is 5 to 25% and 6 to 20% in the longitudinal direction, and the drying elongation in the transverse direction is 15 to 60% and 20 to 55%. In addition, the wet elongation in the machine direction is 15 to 65% and 20 to 55%, and the wet elongation in the transverse direction is 30 to 75% and 40 to 70%. As it has an elongation within this range, it is not excessively stretched during use, and it is possible to gently wipe the object to be cleaned and washed.

Moreover, the natural bamboo wet tissue according to the present invention has a wet tensile strength within the above range without using a wet strength enhancer.

Eco-friendly natural bamboo wipes

The manufacturing process of the eco-friendly natural bamboo wet tissue according to the present invention is not particularly limited, and can be manufactured through a known wet tissue manufacturing process.

The amount of the chemical solution compared to the bamboo fabric in the container should be such that the purified water can keep the bamboo fabric soaked, and the content of the chemical solution is 10 to 50 parts by weight and 15 to 45 parts by weight based on 100 parts by weight of the bamboo fabric. add to If the content of the chemical solution is less than the above range, the cleaning effect may be reduced due to lack of moisture, and on the contrary, if it exceeds the above range, it flows excessively, causing inconvenience during use. Therefore, it is appropriately used within the above range.

The eco-friendly natural bamboo wet tissue according to the present invention uses 100% bamboo fabric and EWG grade 1 material, so there is no problem such as skin toxicity, skin irritation, or skin allergy. In addition, there is no change in components even after long-term storage, so it has excellent durability and can effectively prevent bacterial propagation.

Furthermore, the wet tissue has deodorizing, antibacterial and antifungal effects of bamboo itself, and provides a soft feel when in contact with the skin as well as an excellent touch when used by controlling physical properties such as moisture content and strength.

[Example]

Hereinafter, preferred embodiments are presented to aid understanding of the present invention. However, the following examples are presented to more easily understand the present invention, and the present invention is not limited to the following examples.

Preparation Example 1

(1) Manufacture of bamboo fabric

After adding water at a weight ratio of 1:9 to bamboo pulp having an average length of 3 mm, it was opened to prepare a wrap slurry. After performing a dehydration process to remove water in the lab slurry, it was put into a carding machine and then passed through a web forming machine to produce a bamboo pulp sheet. At this time, the feed speed in the equipment was 200 m/min, and the web forming process was performed with a forming tension of 5 N. Next, a water punching process was performed five times at pressures of 30 bar, 40 bar, 40 bar, 50 bar, and 50 bar using a spray nozzle on the wet bamboo pulp web, and at temperatures of 105 ° C, 110 ° C, 120 ° C, and 130 ° C A 100% bamboo fabric (spunlace nonwoven fabric) was prepared by heat treatment in four stages.

(2) Measurement of physical properties and results

The physical properties of the bamboo fabric prepared in Preparation Example 1 were measured, and the results are shown in Table 1 below. At this time, in Comparative Example 1, a rayon/PET blend fabric widely used as a wet tissue fabric was used, and in Comparative Example 2, a product using the product name of My Bidet was used.

Moisture content and moisture loss after 30 minutes were measured according to Equations 1 and 2, respectively, and tensile strength and elongation were measured according to KS K 0521: 2017, the strip method.

Preparation Example 1 Comparative Example 1 Comparative Example 2 fabric 100% bamboo Rayon/PET blend commercial product basis weight 65 gsm 65 gsm - thickness 0.51mm 0.51mm - moisture content 75.45% 66.80% - Moisture reduction rate after 30 minutes 4.20% 11.50% - Dry tensile strength (N/5 cm) longitudinal 59.8 59.8 15.9 transverse direction 31.2 31.2 - Wet tensile strength (N/5 cm) longitudinal 4.5 4.5 6.1 transverse direction 3.5 3.5 Dry elongation (%) longitudinal 22.1 22.1 5.6 transverse direction 49.6 49.6 - Wet Elongation (%) longitudinal 68.5 68.5 29 transverse direction 79.9 79.9 -

Referring to Table 1, the bamboo fabric according to the present invention has appropriate values for tensile strength and elongation in dry and wet conditions.

In comparison, in the case of the rayon/PET blended fabric of Comparative Example 1, a slight increase in tensile strength was shown, but the water content was low, and the water loss rate after 30 minutes was also greatly reduced. It can be seen that the product of Comparative Example 2 is a product emphasizing softness, and has low tensile strength and elongation characteristics compared to other wet wipes, making it unsuitable for general cleaning or cleaning purposes.
