Description

Natural bamboo fiber wet tissue containing low-harm liquid medicine

Technical Field

The invention relates to a natural bamboo fiber wet tissue containing low-harm liquid medicine.

Background

The wet tissue is a tissue made of paper pulp and is used for various aspects of cleaning and sanitation, cleaning, dish washing, makeup removal and the like, such as skin cleaning and the like.

The wet tissue is a product with the fabric soaked with the liquid medicine, and has the condition that bacteria are easy to propagate because the wet tissue is always in a soaking state. Therefore, in addition to purified water, a preservative must be used for bacteriostasis.

Synthetic preservatives are widely used as preservatives, with the Paraben component being the most representative. However, there are some harmful problems, such as that Paraben causes skin diseases such as allergy or rash, erythema or skin inflammation.

For this reason, attempts are being made to find alternatives to various types of synthetic preservatives. For example, products using a part of natural extracts have been developed [ patent documents 1 and 2], but the natural extracts have not been commercialized because of problems such as poor color and stability.

Problems to be solved

In the invention, in order to be more beneficial to commercialization, the wet tissue is prepared by soaking the fabric in the liquid medicine which is only composed of substances with low harm to human bodies and proved stability, so that the problems of allergy or skin in the past can be solved.

Therefore, the invention aims to provide a natural bamboo fiber wet tissue which comprises a low-harm liquid medicine obtained by soaking a bamboo fiber fabric in a liquid medicine only containing a primary substance of an Environmental Working Group (EWG).

Means for solving the problems

In order to achieve the purpose, the invention provides a natural bamboo fiber wet tissue with a natural bamboo fiber fabric soaked in a low-harm liquid medicine.

The low-hazard liquid medicine comprises purified water, a preservative, a skin conditioner, a natural surfactant, a humectant and additives, but only uses EWG primary raw materials.

Specifically, the preservatives are hydroxyacetophenone and 1, 2-hexanediol, the skin conditioner is centella asiatica extract, the natural surfactant is coco-glucoside, the moisturizer is methyl propylene glycol, and the additives are ethylhexyl glycerin and glyceryl caprylate.

The water content of each piece of the natural bamboo fiber fabric is more than 70 weight percent, and the water loss rate after 30 minutes is less than 5 weight percent compared with the initial water content.

In addition, the gram weight of the natural bamboo fiber fabric is 30-80 gsm, and the thickness of the natural bamboo fiber fabric is 0.3-0.8 mm.

Effects of the invention

The fabric used by the wet tissue is 100% natural bamboo fiber fabric and is prepared by only using liquid medicine of EWG primary raw material with low harm to human body and confirmed stability.

The natural bamboo fiber wet tissue has the advantages that due to the characteristics of bamboo, namely the deodorizing and antibacterial effects, the harm of low-harm liquid medicine components is low, and the stability is high, so that the skin irritation problems such as rash, erythema or skin inflammation and the like when the wet tissue is used can be reduced to the greatest extent. In addition, the components do not change even if the food is stored for a long time, and the food has good endurance and can effectively prevent the propagation of bacteria.

Detailed description of the invention

The wet tissue is prepared by soaking the fabric in the liquid medicine, and comprises disposable wet tissues such as cleaning wet tissues, face washing wet tissues, toilet wet tissues, infant wet tissues, multipurpose wet tissues, makeup removing wet tissues and female physiological wet tissues.

The fabric and the liquid medicine of the wet tissue are made of environment-friendly materials.

The fabric of the wet tissue is made of 100% pure natural bamboo fiber materials and does not contain other natural or synthetic fibers except the bamboo fibers.

The wet tissue liquid medicine only uses EWG first grade raw materials. The Environmental Working Group (EWG) rating is an assessment of the hazard and stability of ingredients, and the lower this figure, the less hazardous and safer.

The present invention will be specifically explained below.

The invention relates to a wet tissue which is prepared by soaking a natural bamboo fiber wet tissue fabric in a low-harm liquid medicine, wherein the low-harm liquid medicine comprises purified water; a preservative; a skin conditioner; a natural surfactant; a humectant; and additives, wherein except for purified water, only EWG primary raw material is used as other ingredients.

Low harm medicinal liquid component

The purified water of the low-harm liquid medicine is purified water filtered by a filtering device through 2 to 8 procedures. The filtering device is formed by combining and connecting various technologies such as precise filtering, reverse osmosis filtering, activated carbon filtering, ultraviolet sterilization and the like in series, is safe from bacteria or germs, and removes substances harmful to human bodies.

The preservative is used together with Hydroxyacetophenone (Hydroxyacetophenone) and 1, 2-Hexanediol (1, 2-Hexanediol). The hydroxyacetophenone and 1, 2-hexanediol are first-class materials of the EWG, and can replace the conventionally used parabens.

In addition to the preservative effect, hydroxyacetophenone is also excellent in stability at any temperature and pH. In addition, the 1, 2-hexanediol is used in a small amount, has a good antiseptic effect, has good moisture retention and antibacterial properties, and has a surfactant structure, so that the mixing degree with other components is high. However, if the amount of the surfactant is excessively added, the viscosity of the chemical solution needs to be greatly reduced and the content needs to be controlled.

The hydroxyacetophenone and the 1, 2-hexanediol are mixed for use in the invention, so that the preservative and the antibacterial power are improved compared with those of respective use, and compared with the conventional hydroxybenzoate preservative, the preservative has the advantages of obviously better preservative performance and less skin irritation. In particular, the hydroxyacetophenone and 1, 2-hexanediol may be included in a weight ratio of 1:10 to 10:1, preferably 1:1 to 5:1, most preferably 1:1 to 3: 1.

The preservative comprising 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 per 100 parts by weight of purified water. If the content is less than the range, the degree of preservation sufficient to replace the conventionally used chemical preservative (i.e., hydroxybenzoate) is not attained, but even if it exceeds the range, the effect is improved to a very small extent and it is uneconomical.

The skin conditioner may be Centella Asiatica Extract (Centella Asiatica Extract) which is the primary substance of EWG. The centella asiatica extract comprises saponin (sapogenins) madecassoside (madecassoside), asiaticoside (asiaticoside) as an effective ingredient, and Asiatic acid (asiaticic acid) and madecassic acid (madecassic acid) as triterpenes (triterpenes) ingredients, and has skin regeneration, antibacterial, antiinflammatory, antioxidant, and skin color improving effects. The centella asiatica extract is obtained by extracting the stem, leaf, root, etc. of centella asiatica with an extraction solvent, i.e., water and/or an organic solvent (ethanol, methanol). The extract means a liquid or solid extract obtained by removing an extraction solvent by freeze drying, vacuum drying, hot air drying, spray drying or the like and then concentrating.

The centella asiatica extract is preferably used in an amount of 0.01 to 10 parts by weight, and 0.1 to 3 parts by weight, based on 100 parts by weight of purified water. Below this range, the desired skin conditioning effect is not achieved, whereas if it exceeds this range, skin problems may be caused.

The surfactant may be a natural surfactant, and well-known products may be used except those harmful to the human body and forbidden. Preferably, the natural surfactant is Decyl Glucoside (Decyl Glucoside), Coco-Glucoside (Coco-Glucoside), Lauryl sugar (Lauryl Glucoside), or apple amino acid foaming agent (apple wash), and Coco-Glucoside (Coco-Glucoside), which is an EWG grade, is used in the present invention. The coco-glucoside is a condensation reaction product of coconut alcohol and glucose, is derived from corn, coconut and palm kernel oils, and can be used for sensitive and fragile skin.

The natural surfactant is preferably used in an amount of 0.01 to 10 parts by weight, 0.5 to 5 parts by weight, relative to 100 parts by weight of purified water. If the amount is less than the above range, the mixing of the components of the liquid medicine cannot be smoothly achieved, whereas if the amount exceeds the above range, skin troubles may be caused or it is uneconomical.

The humectant is used for supplementing and maintaining water, and can be methyl propylene glycol, amyl glycol (amyl glycol), octyl glycol (caprylyl glycol) and the like, and the EWG primary substance methyl propylene glycol is used in the invention.

The humectant is preferably used in an amount of 0.01 to 10 parts by weight, 1 to 8 parts by weight, relative to 100 parts by weight of purified water. Below the range, the moisturizing effect is not obtained, whereas if it exceeds the range, the viscosity increases, thereby decreasing the stability of the components of the liquid medicine.

In addition to the components, conventionally used additives may be included.

Additives that may be used may be pH adjusters, modifiers, corrosion inhibitors, metal ion blocking agents, sweeteners, static electricity protectors, preservatives, meltable agents, antibacterial agents, deodorants, perfumes, and the like. The invention uses EWG primary substances of ethylhexyl glycerin (Ethylhexylglycerin) and Glyceryl Caprylate (Glyceryl caproate) as additives to achieve the skin conditioning effect and simultaneously supplement the preservative effect.

Ethylhexyl glycerin is a vegetable glycerin derived from nature, has a strong moisturizing power, and is used as the skin conditioner and the antiseptic auxiliary. Such ethylhexyl glycerin is preferably used in an amount of 0.01 to 5 parts by weight, 0.1 to 1 part by weight, relative to 100 parts by weight of purified water. The effect is not achieved below the range, whereas if the range is exceeded, the viscosity increases, thereby decreasing the stability of the components of the liquid medicine.

Caprylin is an auxiliary emulsifier, has strong antibacterial power and is known as a natural preservative. The glyceryl caprylate is preferably used in an amount of 0.01 to 5 parts by weight, 0.1 to 1 part by weight, relative to 100 parts by weight of purified water. The effect is not achieved below the range, whereas it is uneconomical because there is not much improvement in the effect beyond the range.

According to one embodiment of the present invention, the low-risk liquid medicine includes purified water, preservatives, skin conditioners, natural surfactants, moisturizers and additives, but only the EWG grade material is used for each ingredient.

Specifically, in the low-risk medicinal liquid composition, the preservatives are hydroxyacetophenone and 1, 2-hexanediol, the skin conditioner is centella asiatica extract, the natural surfactant is coco-glucoside, the moisturizer is methyl propylene glycol, and the additives are ethylhexyl glycerin and caprylic glyceride.

More specifically, the low-risk medical solution of the present invention is composed of, with respect to 100 parts by weight of purified water, 0.1 to 10 parts by weight of hydroxyacetophenone and 1, 2-hexanediol, 0.01 to 10 parts by weight of centella asiatica extract, 0.01 to 10 parts by weight of coco-glucoside, 0.01 to 10 parts by weight of methyl propylene glycol, 0.01 to 5 parts by weight of ethylhexyl glycerin, and 0.01 to 5 parts by weight of glyceryl caprylate.

Bamboo fiber fabric

On the other hand, the bamboo fiber wet tissue disclosed by the invention is made of a fabric made of 100% pure natural bamboo fibers.

The natural bamboo fiber fabric is a pure plant natural fiber material, also called breathable fiber, and is natural cellulose fiber extracted from pure bamboo pulp.

The gram weight (gram per square meter) of the natural bamboo fiber fabric is 30-80 gsm and 35-75 gsm, and the natural bamboo fiber fabric is moderate in thickness when in use, so that the natural bamboo fiber fabric is comfortable to use, and can keep certain strength for absorbing water, oil and other pollutants. In addition, the thickness is 0.3 to 0.8mm, 0.35 to 0.75 mm. The thickness of the natural bamboo fiber fabric can be prepared according to the application, can be thicker or thinner than the range, and can be prepared into a layered form with more than 2 layers if necessary.

The natural bamboo fiber fabric according to the present invention having these basic conditions has physical properties such as moisture content, moisture retention, strength, and elongation to be provided as a wet wipe, by parameter limitation of a dry state and a wet state.

The moisture content (moisture content) is a moisture content at which the moisture content of the sample reaches the moisture equilibrium from a relatively low moisture content in a standard state.

The water content means: the weight of the sample in a wet state is a, and the weight of the sample after drying is b, and the water content is calculated by the following equation 1.

[ mathematical formula 1]

Water content (%) - (a-b) ÷ a × 100

The sample size was 19.2 cm by 0.51 mm (length by width by height), and was a sheet of bamboo fiber fabric having a grammage of 65gsm, and the moisture content was taken as an average of 50 samples.

The weight a of the sample in the wet state is a value measured after a piece of bamboo fiber fabric is soaked in distilled water for 24 hours to naturally absorb moisture and the moisture is balanced. In order to realize the moisture balance, the bamboo fiber fabric before impregnation is placed at the temperature of a drying oven of 100 ℃ for 24 hours, and is used after moisture is completely removed.

The weight b of the sample in the dry state is a value measured after the bamboo fiber fabric is left at a temperature of 100 ℃ in a drying oven for 24 hours and the moisture is completely removed.

The water content of the natural bamboo fiber fabric measured according to the formula 1 is 70-85 wt% and 71-84 wt%. The range of water content is a value that can supplement unnecessary natural evaporation during use or storage. In addition, when the water content is too small or too large, inconvenience in use is caused, and therefore, the range is preferable.

Wet wipes having such a range of moisture content, even when in use, minimize moisture evaporation, and in view of a sufficient feeling of wetness during use, particularly when the wet wipes are used for a period of time, it is necessary to maintain a suitable level of moisture within 30 minutes. The moisture retention may be referred to as a moisturizing ability, and a change in moisture content within 30 minutes, that is, a moisture evaporation rate, may be confirmed by measurement.

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

[ mathematical formula 2]

Water evaporation rate (%) after 30 minutes (a ' -b ')/(a ' x 100)

The sample size was 19.2 cm by 0.51 mm (length, width, height) and the water evaporation rate was an average of 50 samples, which is a piece of bamboo fiber fabric having a grammage of 65 gsm.

The weight a' of the sample in a wet state is a value measured after a piece of bamboo fiber fabric is soaked in distilled water for 24 hours to naturally absorb moisture and reach moisture balance. In order to realize the moisture balance, the bamboo fiber fabric before impregnation is placed at a drying oven temperature of 100 ℃ for 24 hours, and is used after moisture is completely removed.

The weight b' of the sample after 30 minutes is a value of the bamboo fiber fabric measured after the sample in a wet state is left at 25 ℃ and 40% relative humidity for 30 minutes.

The range of the moisture evaporation rate measured according to the above formula 2 of the bamboo fiber fabric according to the present invention is 5 wt% or less and 4.5 wt% or less. The moisture evaporation rate of the wet tissue after 30 minutes is related to the function and the economical efficiency of the wet tissue, and the new wet tissue is needed because the wet tissue is inconvenient to use when the moisture is easily volatilized. The moisture volatilization of the green natural bamboo fiber wet tissue related by the invention in the service life is reduced to the minimum, the moisture evaporation rate after 30 minutes is reduced to below 5 weight percent, and the wet state with high moisture content can be kept when in use.

On the other hand, the wet towel is used by repeated up-and-down or left-and-right movements, and friction is generated by the movements, so that the surface of the wet towel is worn or pilling, and the wet towel may be torn even when the wet towel is seriously worn. To prevent this, the wet wipe must have a tensile strength and elongation in the dry and wet states above a certain level.

The dry tensile strength, wet tensile strength, dry elongation and wet elongation were measured by KS K0521: 2017, the section method, at which time the sample was prepared into a 5cm by 15 cm rectangle, the gauge length was set to 100 mm on a static tensile testing machine, 3 preliminary experiments were performed, and after confirming the elongation at break, the gauge length, the tensile speed were set and the final experiments were performed. The test was conducted by stretching in the longitudinal direction and the transverse direction, respectively, and 5 sets of test pieces were prepared in each direction, and each set was measured 5 times, and the average values of the measured values were tensile strength (N) and elongation (%) in each direction.

And the dry tensile strength and the dry elongation are placed at the temperature of a drying oven of 100 ℃ for 24 hours, the moisture in the sample is completely removed, and then the test is carried out, and the wet tensile strength and the wet elongation are measured after the sample is soaked in distilled water for natural moisture absorption within 24 hours after the dry state, and the moisture is balanced.

The bamboo fiber fabric has longitudinal dry tensile strength of 30-50N/5 cm and 32-48N/5 cm, and transverse dry tensile strength of 15-30N/5 cm and 15-28N/5 cm. In addition, the longitudinal wet tensile strength is 8-15N/5 cm and 9-14N/5 cm, and the transverse wet tensile strength is 4-10N/5 cm and 4.5-9.5N/5 cm.

When the wet tissue has dry and wet tensile strength within the range, the wet tissue has good use comfort and can not be torn when in use. In this case, the wet towel feels soft when the transverse wet tensile strength is high, so that the transverse wet tensile strength is high to prevent damage during use.

In addition, the wet wipe is damaged in terms of wiping properties and tearing properties, and the wet tensile strength and the dry tensile strength are related to each other. Specifically, the ratio of the dry tensile strength in the machine direction/the dry tensile strength in the cross direction is preferably 1.5 to 3 and 1.8 to 2.5, and the difference between the dry tensile strength in the cross direction and the wet tensile strength in the cross direction is preferably 20N/5 or less and 18N/5cm or less. Satisfying this range maintains the balance between softness and firmness of the wet wipe.

In addition, the invention relates to a bamboo fiber fabric, wherein the longitudinal dry elongation is 5-25% and 6-20%, and the transverse dry elongation is 15-60% and 20-55%. In addition, the longitudinal wet elongation is 15-65% and 20-55%, and the transverse wet elongation is 30-75% and 40-70%. With the elongation in this range, the article can be cleaned and washed by wiping the article gently without being excessively elongated.

In addition, the natural bamboo fiber wet wipe according to the present invention has the wet tensile strength in the above-mentioned range even without using the wet paper strength enhancer.

Wet paper strength enhancer of green natural bamboo fiber wet tissue

The process for producing the green natural bamboo fiber wet wipe according to the present invention is not particularly limited, and can be produced by a known wet wipe production process.

The adding amount of the liquid medicine relative to the bamboo fiber fabric in the container needs to reach the degree that the pure water can completely wet the bamboo fiber fabric, and the liquid medicine content of 100 bamboo fiber fabrics is 10-50 parts by weight and 15-45 parts by weight. If the content of the chemical liquid is less than the above range, the cleaning effect is deteriorated due to insufficient moisture, whereas if the content is more than the above range, running water due to excessive moisture causes inconvenience in use, and thus the chemical liquid should be suitably used within the above range.

The green natural bamboo fiber wet tissue uses 100% of bamboo fiber fabric and EWG first-class substances, and does not have the problems of skin toxicity, skin irritation, skin allergy and the like. In addition, the composition is not changed even after long-term storage, has excellent endurance, and can effectively prevent bacterial propagation.

Further, the wet wipe has deodorant, antibacterial and antifungal effects of bamboo itself, physical properties such as controlled moisture content and strength, excellent tactile sensation in use, and soft touch feeling when contacting the skin.
