Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cleaner that exhibits excellent removal performance against various contaminants and does not require rinsing water.

(Field of Application of the Invention) The cleaner of the present invention exhibits excellent performance in removing various pollutants attached to human limbs and various objects, and since rinsing water is not required, it can be used in various applications. It can be advantageously used to remove various contaminants from various objects, including human bodies and machinery and equipment, which are contaminated with various contaminants in the field.

(Prior Art) There are various types of conventional cleaning agents and cleaners. For example, there were those whose main ingredients were soap or strong alkaline agents, those which used neutral cleaning agents such as nonionic surfactants and anionic surfactants, and those whose main ingredients were organic solvents such as thinner and benzene. However, these conventional cleaning agents, such as those containing soap, strong alkaline agents, organic solvents, etc. as main ingredients, are harmful to the human skin, etc., even if they have an excellent effect on removing pollutants, so they should not be used. A large amount of rinsing water was required afterwards. In addition, products based on neutral detergents have relatively little adverse effect on the skin, but they have poor pollutant removal effects and also require rinsing with water after use.

(Problems to be Solved by the Invention) The present invention seeks to provide a cleaner that exhibits an excellent removal effect on various contaminants including various oils and does not require rinsing water. It is.

(Means for solving the problem) The above problem could be solved by a cleaner made of a specific tissue.

That is, the cleaner of the present invention that does not require rinsing water contains 0.5 to 15% by weight of solid waxes, 0.1 to 5% by weight of silicone oil, 1 to 10% by weight of nonionic surfactant, and 1 to 5% by weight of anionic surfactant. , liquid paraffin 8-20% by weight, water-soluble polymer compound 5-20% by weight
10% by weight, and the balance consists of water.

The method of using the cleaner of the present invention is to apply the cleaner to areas contaminated with various contaminants including oils attached to human limbs, machinery, equipment, and various other objects. When rubbed (i.e., rubbed) with a fingertip, the contaminants fall off together with the cleaner in the form of small clumps, just as characters on a pencil are erased by an eraser, and can be easily removed. Contaminants to be removed include animal and vegetable oils, mineral oils, cooking oils, machine oils, fuel oils, greases, inks, paints, tars, and other general Various pollutants can be mentioned.

In detailing the cleaner of the present invention, the solid waxes are present in an amount of 0.5 to 15% by weight based on the total amount of all essential ingredients of the present invention. Examples of solid waxes include higher fatty acids such as stearic acid and palmitic acid; higher alcohols such as cetanol;
Examples include higher alcohol fatty acid esters such as spermaceti wax and beeswax; solid paraffin wax; and various other synthetic waxes. Solid waxes enhance the spreadability of the cleaner of the present invention, making it easier to use, and also serve to stabilize the emulsion by maintaining the emulsion balance of the cleaner as a whole. If the content of solid waxes is too low, the spreadability will be poor and it will be difficult to use; if it is too high, the emulsification balance of the cleaner will be disrupted, causing separation of oily and aqueous components, so the solid wax should be within the above range. Blend with.

The silicone oil is present in an amount of 0.1 to 5% by weight based on the total amount of all essential components of the invention. Various silicone oils can be used, such as methyl silicone oil, dimethyl silicone oil, and methylphenyl silicone oil. Silicone oil helps dissolve oily contaminants, making their removal easier, and acts to protect the skin. However, if the amount is too large, the oil containing the contaminants will not solidify when rubbed with your hands, making it difficult to remove the contaminants by turning them into small agglomerates. Mix within.

The nonionic surfactant is present in an amount of 1 to 10% by weight based on the total amount of all essential components of the invention. Various nonionic surfactants can be used. For example, sorbitan monolaurate, polyoxyethylene sorbitan tristearate, sucrose fatty acid ester, polyoxyethylene cetyl ether, polyoxyethylene lauryl ether, cholesterol and lecithin are used. The nonionic surfactant works in cooperation with the anionic surfactant to emulsify the cleaner and also emulsifies and removes contaminants such as oily contaminants. In particular, if a nonionic surfactant is not added,
The emulsion stability of the cleaner itself deteriorates. However, if the proportion of nonionic surfactant is too high, when removing the contaminants by rubbing with your hands, the lumps surrounding the contaminants will become soft and difficult to remove, or the nonionic surfactant On the other hand, depending on the type of agent, the mass enclosing the contaminants may become too hard, making it difficult to remove the contaminants sufficiently, so the nonionic surfactant is blended within the above range.

The anionic surfactant is present in an amount of 1 to 5% by weight based on the total amount of all essential components of the invention. Various types of anionic surfactants are used as the anionic surfactant. For example, alkali soaps of various fatty acids, higher alcohol sulfate ester salts, fatty acid alkanolamides, and alkali metal salts of glutamates of various fatty acids are used. The anionic surfactant works together with the nonionic surfactant to emulsify the cleaner and also emulsifies and removes contaminants such as oily substances. It also has the effect of softening the oily feeling on the skin after using the cleaner, giving it a non-sticky and refreshing feel. Furthermore, if an anionic surfactant is not added, the ability to remove contaminants by rolling them into small particles will be reduced. However, when the proportion of anionic surfactant is too high, the cleaner itself gels and becomes a hard rubber-like lump, which makes it difficult to use.
The anionic surfactant is blended within the above-mentioned range because it becomes impossible to take an appropriate amount with a fingertip, etc., and the spreadability deteriorates, making it impossible to sufficiently suspend contaminants.

The liquid paraffin is present in an amount of 8 to 20% by weight based on the total amount of all essential components of the invention. The liquid paraffin is preferably a kerosene fraction of petroleum that has been highly purified to be odorless, but it is also possible to use a paraffin that retains some petroleum odor depending on the purpose of the cleaner. Liquid paraffin has an excellent ability to dissolve various contaminants, especially various oils, inks, tars, etc., making them easier to remove.
However, if the blending ratio of liquid paraffin is too high, there will be problems such as roughness of the skin, so the liquid paraffin should be blended within the above-mentioned range.

The water-soluble polymer compound is present in an amount of 5 to 10% by weight based on the total amount of all essential components of the present invention. Examples of the water-soluble polymer compound include polyvinyl alcohol, polyvinylpyrrolidone, polyvinyl acetate, sodium carboxymethyl cellulose,
Examples include gum tragacanth, xanthan gum, and locust bean gum. The most preferred water-soluble polymer compound is polyvinyl alcohol. The water-soluble polymer compound has the effect of enveloping the contaminant separated from the contaminated object by the action of each of the above-mentioned components, rolling it into small rubber-like lumps, and separating it from the contaminated object. However, if the blending ratio of water-soluble polymer compounds is too high, the cleaner will not be able to maintain an appropriate hardness, and will not be able to sufficiently spread on the surface of the contaminants, and the contaminants will be sufficiently removed by friction. The water-soluble polymer compound is blended in the above-mentioned proportions, since it will turn into small lumps before it can be suspended.

The cleaner of the present invention further contains water as an essential ingredient. The mixing ratio of water is the balance of each of the above-mentioned essential components. And the proportion of water relative to the total amount of all essential components can vary within a wide range, but usually from 30 to 85% by weight, preferably 40% by weight.
~80% by weight. By keeping the cleaner of the present invention in a stable aqueous emulsion system, the water
It not only facilitates its use, but also serves to promote the contaminant-removing action of each component, particularly nonionic surfactants and anionic surfactants.

In addition to the above-mentioned essential components, the cleaner of the present invention may contain other components, if necessary, within a range that does not impair the emulsion stability, detergency, feel of use, etc. of the cleaner. For example, various liquid oils including squalane, liquid animal and vegetable oils such as olive oil, mineral oils such as vaseline, etc. can be blended. Furthermore, glycols such as 1,3-butylene glycol, propylene glycol, and polyethylene glycol, polyhydric alcohols such as glycerin and sorbitol, polysaccharides, and the like can be blended as wetting agents. Furthermore, as a preservative, for example, benbrozoic acid, its salts and esters, etc. can be blended, as a flavoring agent, various blended fragrances etc. can be blended, and as a coloring agent, harmless to the human body. For example, legal dyes and natural dyes that can be used in pharmaceuticals, cosmetics, etc. can be blended.

The amounts of each of these components (optional components) that are added to the cleaner of the present invention as necessary are as follows:
This is completely unrelated to the calculation of the blending ratio of the essential components of the cleaner of the present invention described above.

The cleaner of the present invention has various excellent advantages as described below.

(i) This cleaner can remove pollutants extremely easily by simply applying it to the contaminated area and rubbing it with your fingertips. Can be removed. However, since it does not require any rinsing water, it can be used even in places where there is no water.

(ii) Even if the cleaner gets on the skin or if it is not rinsed with water after using the cleaner, it is completely harmless and there is no risk of skin irritation, cracking, etc. after using the cleaner. It's crunchy.

(iii) Stubborn contaminants that are difficult to remove with soap, etc. can be easily removed.

(iv) This cleaner is free from deterioration during storage. In other words, it does not deteriorate even if stored for a long time or under high temperatures (below 40°C) in summer. However, some layer separation may occur, but even in that case, the quality does not change, and the mixture returns to its original state simply by mixing, and the efficacy is not affected.

After the temperature reaches 40℃ or less, add component (l),
Cooled to room temperature.

The resulting cleaner was a stable emulsion type cleaner. When this cleaner is applied to areas contaminated with various types of contaminants and rubbed by hand, the removed contaminants and cleaner fall as small rubber-like lumps, making it easy to remove the contaminants from the contaminated object. I was able to do that. In addition, when the contaminated object is a human limb, it feels refreshing after use, regardless of whether it is rinsed with water or not.
No abnormalities such as rough skin or strange odor were observed. Furthermore, the cleaner itself had excellent stability, and showed no abnormalities even when stored at 40°C for 30 days or at 1 to 5°C for 90 days.

Comparative Example 1 In Example 1, waxes, that is, components
A cleaner was prepared in the same manner as in Example 1 except that (a) to (c) were not mixed at all. However, it was difficult to form small lumps. Also, the particles that had formed into small clumps were too soft and stuck to the skin, making it impossible to remove them easily. Furthermore, when this cleaner was stored at 40°C for 7 days, a transparent separated layer appeared at the bottom, and after 15 days, it was observed to be largely separated into two layers.

Comparative Example 2 A cleaner was prepared in the same manner as in Example 1 except that the nonionic surfactant, that is, component (d) was not added at all.

The product cleaner was separated into an aqueous phase and an oil phase and was not emulsified. That is, when stirred, it temporarily became an emulsified state, but when left to stand, it easily separated into two layers over time.

Comparative Example 3 A cleaner was prepared in the same manner as in Example 1 except that no anionic surfactant, that is, component (e) was added.

The product cleaner, like the product of Comparative Example 1, had a strong oily feel, did not easily form into small lumps even when rubbed with the palm of the hand, and adhered to the skin and was difficult to remove. Also,
The emulsification was unstable and easily separated into two layers.

Further, in Example 1, an anionic surfactant,
That is, when a cleaner was prepared in the same manner as in Example 1 except that the amount of component (e) was increased to 7%, the product cleaner was gelled and hard.
It was difficult to use.

Comparative Example 4 A cleaner was prepared in the same manner as in Example 1 except that liquid paraffin, that is, component (g) was not added at all.

The product cleaner was extremely poor in its ability to remove contaminants based on various oils and stains such as paint and ink, and could hardly demonstrate its performance as a cleaner.

Comparative Example 5 In Example 1, the water-soluble polymer compound, that is, the component (h) was not blended at all, but the rest was as in Example 1.
A cleaner was prepared in the same manner.

Although the product cleaner was able to dissolve oil stains and the like onto the surface of the cleaner, it was not possible to roll them into small clumps and drop them even when rubbed with a finger.
