Description

Wet Wiper {WET WIPER}

The present invention relates to a wet wiper.

In recent years, as the aging society develops, the number of the elderly who need nursing care has increased. In addition, some people, even if they are not elderly, will only lie down due to illness or accident.

Conventionally, when wiping such a person cleanly, wet tissues for towels and wet towels and wet wipes for use with water have been used. Such wet tissues are mainly impregnated with a cleaning chemical liquid in a nonwoven fabric or a water-decomposable sheet and the like, and development of components having a high cleaning effect and cleaning materials containing them has been performed. For example, in the invention according to Japanese Patent Application Laid-Open No. 3-16542, it contains paraoxybenzoic acid ester having antibacterial and antifungal properties and propylene glycol and 1,3-butylene glycol, which are solvents for easily dissolving it in a chemical solution. A food item is proposed. Further, in the invention according to Japanese Patent Application Laid-Open No. 4-183472, a bactericidal disinfecting fragrance containing ethanol as an antibacterial and antifungal agent has been proposed.

However, although the chemical liquid contained in the above-mentioned wet tissue conventionally is excellent in removing a dirt, when it contains ethanol, sebum which serves as a barrier to protect skin is removed. And since the invasion of various germs easily occurs from the part where sebum was removed, in the case of wet tissues containing ethanol, ethanol functions as a disinfectant, but a situation arises that various germs are easily invaded from the outside. do. In addition, since the conventional wet tissue does not contain a moisturizing agent at all or contains a sufficient amount of a moisturizer, there is a possibility that the skin may be roughened in an elderly person whose skin is easy to dry. Furthermore, conventional wet tissues do not contain components that have the function of removing old, hardened dead skin without hurting the skin, and need to be wiped with a strong force to remove old dead skin cells that become waste products of the skin. It will damage the surface of the skin.

That is, according to the conventional wet tissue, sebum is removed according to the usage, and the skin becomes more dry, moisture is not sufficiently moisturized, and the waste of the skin is not further damaged without damaging the surface of the skin. There was a case that it could not be removed.

In order to solve this problem, the invention according to JP-A-2002-209788 discloses a wet wiper containing a plant extract extract having a moisturizing action and suitable for nursing and nursing care.

The "wet wiper" which concerns on this invention is a sheet | seat in which the liquid-absorbing fiber is impregnated with the chemical | medical solution, and it means the thing for culturing, and a wet tissue, a wet towel, etc. correspond.

"Keratin softening component" according to the present invention refers to a component that restores the metabolism of the skin to a normal state by softening old and hardened keratin and promoting desquamation, and used in the present invention is α-hydroxy acid. to be.

In addition, the "natural moisturizing factor" is a protective factor in the original keratin of the skin, which has an effect of not releasing moisture in the stratum corneum, and when reduced, the skin tends to become dry.

In addition, "plant extract extract" is the extract extracted from a plant, and in this invention, the plant extraction extract with moisture retention is mentioned especially.

Next, an embodiment of the wet wiper of the present invention will be described.

The wet wiper of the present invention is a liquid absorbent and is formed of a thick sheet of soft fibers, especially a nonwoven fabric. As hydrophilic fiber, it can select from fibers, such as rayon, cotton, and pulp. It may also include both rayon and cotton. Furthermore, synthetic fibers selected from polypropylene, polyester, polyethylene and the like subjected to hydrophilization treatment can be blended. As said synthetic fiber, the composite fiber, such as a core and a cis polypropylene, a core polypropylene, and a cis polyethylene, can be used, for example. Moreover, the fiber formed from individual resin may be sufficient. As the hydrophobic fiber, thermoplastic synthetic fibers such as polyethylene, polypropylene, polyamide-based synthetic fibers, polyester, or composite fibers thereof can be used.

It is preferable that the fiber mixing ratio of such a nonwoven fabric is in the range of 0.5 wt% or more and 70 wt% or less of the hydrophilic fiber. If it is 0.5 weight% or less, the content of the liquid is too small, making it difficult to wipe off, and it becomes a stiff nonwoven fabric with poor touch. Moreover, at 70 weight% or more, it becomes difficult to mix | blend in a balance with respect to productivity and cost. These fibers are mechanically entangled with each other, are welded by heat, or maintain their form as nonwoven fabrics by entanglement and welding. In particular, when a wet wiper having a good feel is required, it is preferable that the fibers are mechanically entangled.

Moreover, it is preferable that such nonwoven fabric is a basis weight of 30-70 g / m <2>, Furthermore, 40 g / m <2>. It is preferable that it is above. 30 g / ㎡ Below, when the sheet becomes too thin and wipes off, it causes trouble, and 70 g / m 2 If it becomes abnormal, it will become difficult to clear, and it will cause difficulty when wiping a minute part.

In the wet wiper of this invention, it is obtained by impregnating the nonwoven fabric mentioned above with the liquid containing a keratin softening component, a natural moisturizing component, and a plant extract extract as an impregnation liquid.

The keratinized soft component used in the present invention is preferably one or more of malic acid, citric acid and lactic acid. Such keratin softening components are α-hydroxy acids having a carboxyl group and a hydroxyl group, generally called fruit acids. These fruit acids penetrate into the thickened stratum corneum to release the bonds between the keratin and promote the release of keratin, thereby promoting the normal metabolism of the skin. In older people, metabolism is lowered, the stratum corneum becomes thicker and harder, and the skin becomes dull. Such symptoms can be ameliorated by using the keratin softening component.

Such keratin soft component is preferably contained in a proportion of 0.05 to 3.0% by weight of the total amount of liquid impregnated into the wet wiper.

Examples of the natural moisturizing factor used in the present invention include pyrrolidonecarboxylic acid soda (PCA-Na), urea, uric acid, amino acids and lactates, and the use of PCA-Na is particularly preferred. This is because PCA-Na has a higher moisturizing effect than other natural moisturizing factors. PCA-Na is a hygroscopic component contained in the stratum corneum of human skin and is a sodium salt of pyrrolidonecarboxylic acid, which is one of natural moisturizing factors that retain moisture. The natural moisturizing factor is a component which is well extracted with water, and has a strong hygroscopicity, thereby retaining skin moisture. When the PCA-Na adheres to the skin, it absorbs and retains moisture attached to the skin, thereby moisturizing the skin.

Such natural moisturizing factor is preferably contained at a ratio of 0.05 to 1.0% by weight of the total amount of liquid impregnated in the wet wiper. If the blending ratio of the natural moisturizing factor is less than 0.05% by weight, a sufficient effect for moisturizing the skin cannot be obtained.

The plant extraction extract used for this invention includes a scrubber extract, a yellow-wall extract, a 300 sec extract, a cypress thiol, a chamomile extract, etc., Use of any 1 or more of these is preferable. In the present invention, only moisturizing plant extract extract is used, and no moisturizing plant extract extract is used. When these plant extract extracts are contained, moisture can be imparted to the skin when the skin is cleaned. Moreover, when extracting these plant extraction extracts, it is preferable to use 1 or more types of polyhydric alcohols of 1, 3- butylene glycol, propylene glycol, and glycerin.

It is preferable that the above-mentioned plant extract extract is contained in the ratio of 0.02-5.0 weight% of the total liquid amount impregnated in a wet wiper.

In the wet wiper impregnation solution of the present invention, a moisturizer, an oil, a surfactant, a pH adjuster, an antibacterial and antifungal agent, an antioxidant, a metal ion sequestrant, a deodorant, and an anti-inflammatory agent, as necessary, within a range that does not impair the object of the present invention. , Coolants, fungicides and the like can be blended.

Examples of the moisturizing agent include polyethylene glycol, sodium hyaluronate and oil, and olive oil, petrolatum and squalene are used, and any one or more of these is preferable.

Such a moisturizing agent is preferably contained at a ratio of 0.1 to 5.0% by weight of the total amount of liquid impregnated into the wet wiper. In particular, when the blending ratio of the moisturizing agent is less than 0.1% by weight, it is not preferable because a sufficient moisturizing action may not be obtained.

As a pH adjuster, it is preferable that it is 1 or more types chosen from sodium lactate, sodium malate, potassium hydroxide, sodium citrate, for example. Moreover, by mix | blending such a pH adjuster, pH is adjusted to the weak acidity of 3 or more and 6 or less, and skin irritation to an elderly person or a person with weak skin can be reduced.

Examples of the corrosion / mildew inhibitor include paraoxybenzoic acid esters, cetylpyridinium chloride, benzalkonium chloride, and benzoate, and the corrosion / mildew inhibitor prevents propagation of germs to rayon and cotton of the wet wiper. The amount required to add may be added. In addition, since paraoxybenzoic acid esters are poor in solubility in water, solvents such as 1,3-butylene glycol, propylene glycol, glycerol, methanol, and ethanol having good solubility with such esters are added to the wet wipes described above. Although it becomes an impregnation liquid, it is preferable not to contain lower alcohols, such as methanol and ethanol, in order to reduce irritation to skin.

In addition, the pH adjuster added to the above-mentioned impregnation liquid is suitably added after all other necessary solvents are blended, and finally, it adjusts to the range of pH 3 or more and 6 or less weakly acidic. PH at this time is a measured value in normal room temperature.

This impregnation liquid is impregnated in the range of 150 to 300% by weight based on the dry weight of the nonwoven fabric. If the amount of the liquid is less than 150%, the entire thick nonwoven fabric cannot be sufficiently impregnated, and the keratin softening action by the aforementioned keratin softener, the moisturizing action by the above-mentioned natural moisturizing factor, and the moisturizing action by the above-mentioned plant extract extract on the skin. I can't save enough. In addition, the sufficient wiping effect of the wet wiper is not exhibited. In addition, if it is more than 300%, the nonwoven fabric cannot be impregnated, the skin after wiping is too wet and unpleasant, and if left unattended, the skin is easily inflamed.

Assessment Methods

Easy to wipe

A monitor in which caregivers were assumed to be wiped out of 20 forearm monitors (a caregiver) presumed to be an elderly man lying down. The above-mentioned caregiver was asked whether the caregiver felt pain or discomfort when wiped off. In Table 1a and Table 1b, in the evaluation regarding the ease of wiping, when the caregiver monitor and the caregiver monitor all felt good, O was displayed, and the case where no one felt good was indicated by x.

Affinity test to skin

The said caregiver was observed by visually confirming the skin condition of a caregiver monitor immediately after the said test. In addition, it observed by visually confirming the skin condition after 3 hours after the test. In Table 1a and Table 1b, especially the case where skin roughness or a red group was not recognized was represented by O, and the case where roughness or red group was recognized was represented by x.

Moist

Thirty caregiver monitors different from the above test were tested by having the caregiver monitors different from the above test use 40 wet wipes for five consecutive days. It was observed by visually confirming the skin condition of the caregiver monitor 5 days after the start of the test. Evaluation criteria were made into 0 when the number of the caregiver monitors which answered that it was moist was 15 or more, (triangle | delta), and 5 or less for 5 or 14 people.

From the result of Table 1a and Table 1b, the following is clear. That is, in the Example, since it contains the liquid absorptive rayon fiber, and also contains the plant extract extract extracted with malic acid, PCA-Na, and 1, 3- butylene glycol, it is easy to wipe and affinity with skin With respect to this good and moist, all good results were obtained.

In the same manner as in Examples 2 and 3, the impregnation solution contained 0.05 to 2.0 mass% of malic acid, 0.05 to 1.0 mass% of PCA-Na, and 0.02 to 0.2 mass% of plant extract extracts A, B, and C, respectively. Also in the case of containing it in the same manner, in the same manner as in Example 1, good evaluation could be obtained for each evaluation of the above-mentioned ease of wiping, affinity to the skin, and moisture.

On the other hand, in the comparative example 1, the evaluation about the moisture to skin was low compared with Example 1, and the result that the moisturizing effect was not so high was obtained. Accordingly, it has been demonstrated that the combination of malic acid and plant extract extract has a low moisturizing effect.

In addition, in Comparative Examples 2 and 3, the combination of only PCA-Na and plant extract extract and the combination of malic acid and PCA-Na had fewer monitors than those of Example 1 to realize the moisture of the skin. The effect that there is little effect to care was obtained.

Moreover, in Comparative Example 4 and Comparative Example 5, it could not be realized as compared with Example 1 regarding moisture. Therefore, only the plant extract extract was confirmed to have little effect of moisturizing the skin.

In addition, in Comparative Example 6, deterioration of the skin condition was confirmed in both immediately after use and after 3 hours elapsed with respect to the affinity to the skin, and almost no one could realize the moist feeling. This is because the extract extracted with ethyl alcohol which is lower alcohol was used, and ethyl alcohol was used as a solvent.

In addition, in Comparative Example 7, it was evaluated that it was difficult to wipe off compared with Example 1, but this is because the impregnation liquid was not received in the sheet because no liquid-absorbing fibers were contained.

Furthermore, the impregnation liquid of Example 1 shown in Table 1a and Table 1b was impregnated 250% by mass ratio with respect to the nonwoven fabric mentioned above, and the wet wiper was obtained. A skin surface hydrometer (SKICON-200, manufactured by IBS), which is a high frequency impedance measuring instrument, is placed in a constant temperature and humidity chamber having a temperature of 20 ° C. and a humidity of 60% for 20 minutes, and then the inside of the forearm is wiped 10 times with the above-mentioned wet wiper. Measured as This conductance is a value expressed in units of microsiemens (micro Siemens), the higher the value, the more moisture there is in the skin. As a result of the test, the conductance after about 10 minutes after wiping with the wet wiper described above was 61 μS, which was about 5 times as compared to before the start of the test (12 μS).

According to the present invention, since it contains a keratin softening component, a natural moisturizing factor, and an extract extracted from a natural plant, it is possible to normalize skin metabolism and impart moisture to the skin.
