Description

TECHNICAL FIELD The present invention relates to a kitchen detergent for cleaning vegetables, fruits, tableware, and cooking utensils.

[Conventional technology]

With respect to this type of kitchen detergent, the needs from both aspects of mass have been increasing with the diversification and rationalization of the living environment, and a wide variety of detergents are commercially available.

That is, due to westernization of eating habits and the trend toward high nutrition, eating habits mainly composed of fats and proteins have caused severe deterioration of oil stains on tableware and cooking utensils. Fresh vegetables,
Due to the need to remove pesticide residues associated with the ingestion of fruits, kitchen detergents with higher detergency and degreasing power have been demanded.

However, on the other hand, it is also true that the number of cases of damage in the dermatological field, which is thought to be mainly due to household detergents, is increasing. According to the "Health Damage Hospital Monitor Report on Household Goods" of 1985, which was compiled based on the report from the Dermatology Monitor Hospital commissioned by the Household Goods Safety Office of the Ministry of Health and Welfare, the There are 464 cases of health hazards presumed to be related to articles, and 156 cases of household detergents were reported in this year, about 34 in total.
Account for the percentage. In particular, the fact that progressive palmar keratoses account for the majority in this case cannot be overlooked. This symptom is reported to be relatively rare in all cases as it takes a long time to treat and the patient is unable to leave daily water work which prevents improvement of the symptom.

Furthermore, the number of cases of damage such as contact dermatitis caused by the use of rubber and vinyl gloves used to avoid this condition is increasing.

[Problems to be solved by the invention]

In view of the above situation, there has been a demand for the development of a kitchen detergent that sufficiently satisfies the detergency and degreasing power, which are the original purposes of the detergent, and that does not damage the skin such as the palm of a finger.

Human skin tissue is mainly composed of tough keratinized cells, sebum membranes composed of sebum sweat secreted on the epidermal surface, and natural moisturizing factors present in the epidermal layer to enhance the water retaining ability.

However, detergent components with strong detergency and degreasing power partially decompose the keratinous substance having this protective function and wash away the sebum membrane and natural moisturizing factor, resulting in dryness of the epidermis and acceleration of keratinization. Repetition causes progressive palmar keratoses.

Since kitchen detergents are mainly intended to remove and clean oils and fats and protein components, many products are satisfactory in terms of cleaning performance, but none are satisfactory in terms of skin surface protection and damage prevention. The present situation is that the composition and the amount of the active agent are variously changed so that the composition is such that the skin is not damaged as much as possible.

Currently available kitchen detergents can be broadly classified into the following three types.

1. Soken type 2. Synthetic vegetable type 3. Synthetic petroleum type Cleaning performance increases in the order of 1 → 3, but skin damage due to degreasing action also increases in the same order. Although Stone Kendip No. 1 has few complaints of skin damage, it seems that the complaint about the original purpose of detergency cannot be overwhelmed.

[Means for solving the problem]

Thus, the present invention has been earnestly researched and developed in view of the above-mentioned circumstances, and by using a vegetable or petroleum-based synthetic detergent, a satisfactory cleaning power and degreasing power, which are the original purpose of the kitchen detergent, can be obtained. The purpose of the present invention is to provide a kitchen detergent that is capable of maintaining and recovering the physiological functions such as the skin's defense function, respiratory function, and secretory function, which are originally possessed by the living body, in a normal state. is there.

That is, the present invention relates to a kitchen detergent characterized by using a vegetable or petroleum-based synthetic detergent and blending it with a ferrous (III) iron salt to achieve the above object.

[Function of the invention]

Certain iron (III) salts, when dissolved in water or adhere to water-containing surfaces such as the skin surface, induce reactions that are significantly different from ionic reactions in ordinary aqueous systems by suppressing various ionic reactions. It seems that It has been found that the use of such a kitchen detergent containing a ferric (III) salt can prevent skin damage due to a vegetable or petroleum synthetic detergent having excellent detergency and restore the skin to a normal state. did.

(Example of the invention)

 Hereinafter, the present invention will be described in detail.

The divalent and trivalent iron salts used in the kitchen detergent of the present invention are iron hydrochlorides, sulfates, phosphates, nitrates and other inorganic salts and formates, which exhibit intermediate properties between divalent iron and trivalent iron, Organic salts such as acetate and propionate. For example, known compounds include complex salts of divalent iron and trivalent iron such as Fe ₃ Cl ₇ , XH ₂ O, and Fe ₃ Cl ₈ · XH ₂ O. Examples of iron salts include Fe ₃ Cl ₅ .XH ₂ O described in JP-A-59-190226 and JP-A-60-186581 of the present inventor.
Is mentioned.

When blending the above divalent and trivalent iron salts in the kitchen detergent,
Properties of the detergent, depending on the type of compounding agent, not only by blending the divalent and trivalent iron salts alone, for example, sodium chloride, sodium sulfate, magnesium chloride, diatomaceous earth, bentonite, silica, inorganic substances such as alumina, Further, it is preferable to use an organic substance such as vegetable fiber, protein, and lipid as a carrier to carry a divalent and trivalent iron salt.

The amount of the divalent and trivalent iron salt, including the carrier, is 10 ^-5 to 10 ^-15 g, preferably 10 ^-9 to 10 ^-12 g per 100 g of the detergent. The effect of divalent and trivalent iron salts is diminished if the compounding amount is more or less than this range. The pH of the detergent used is 3 ~
A wide range of 11 is acceptable, but pH 5-8 is the most preferred pH
Range.

In the kitchen detergent of the present invention, solvents, fats and oils, surfactants, preservatives, fragrances, pigments, and the like which are usually added to the detergent are used without any trouble. Since it is an extremely small amount, it may be contained in the chelating agent, phenols, mercaptans, cationic activators, etc., which are reactive with iron salts, as a raw material or as a mixed impurity, when the divalent and trivalent compounds of the present invention are contained. Since the effect of iron salts may be suppressed, sufficient check is required in advance.

There are various methods such as a bioassay method for checking the effect of the divalent and trivalent iron salt of the present invention, and the following method is mentioned as the simplest method.

To the sample as it is or to an appropriately diluted sample, add an appropriate amount of reagent copper powder to disperse, add nitric acid TS,
In the case of a normal detergent, naturally copper powder and nitric acid react to generate H ₂ gas, and the liquid exhibits a blue color due to the production of copper nitrate, but in the case of the detergent of the present invention containing a divalent and trivalent iron salt, , The liquid does not color and no H ₂ gas is generated. This is the dissolution of copper powder,
And the ionic reaction appears to be hindered by the ferrous salt. In the same manner, it is possible to test the compatibility of the mixed raw materials with divalent and trivalent iron salts.

According to the above method, a kitchen detergent having the same function as a nonionic reaction system on a normal skin surface can be obtained.

[Effect of the Invention] As described above, the kitchen detergent containing a ferric (III) iron salt of the present invention can prevent skin damage caused by the detergent even when a vegetable or petroleum synthetic detergent having excellent detergency is used. The effect of preventing and normalizing the function of the skin has the following effects.

(1) Enhancement of physiological functions of skin Physiology of skin such as physiological functions originally possessed by skin tissues, that is, normal keratin metabolism of the stratum corneum of the epidermis and control of sebum membranes by normalization of sebum secretion and water evaporation. Normalization of function can be promoted.

(2) Enhancement of regenerative ability The tissue of the skin has the ability to normalize and recover abnormalities in metabolic function, damage to the stratum corneum caused by the external environment, and abnormalities on the skin surface due to abnormalities in excess and deficiency of sebum and water. However, by using the detergent of the present invention, the regeneration function can be enhanced and recovered more quickly. For example, normalization of hyperkeratosis such as progressive keratokeratosis, removal of spots due to pigmentation, and recovery of epidermal abnormality caused by lack of sebum membrane such as cracks and red fins can be rapidly achieved.

(3) Enhancement of adaptability to environmental changes The ability of the skin to adapt to exposure to external stimulants, cold, heat, and ultraviolet rays can be enhanced, and the original protective function of the skin can be maintained. For example, sensitizing skin injuries can be prevented by suppressing the intrusion of antigen substances from the outside,
In addition, it is possible to keep the skin in a beautiful state by controlling the formation of the skin film according to the environment.

(4) Prevention of abnormal growth of microorganisms It is possible to eliminate or prevent skin troubles such as inflammation and purulence due to abnormal growth of microorganisms and skin-resident bacteria from the outside. In addition, the addition of divalent and trivalent iron salts eliminates the need for preservatives that are usually added, and can prevent sensitizing skin damage caused by preservatives.

(5) Inhibition of harmful ion reactions By suppressing harmful ion reactions and free radical reactions such as skin irritation by external chemicals and formation of lipid peroxide by ultraviolet rays, aging of the skin can be prevented. In addition, since the oxidative deterioration of the detergent can be prevented by blending the divalent and trivalent iron salt, it is not necessary to use an antioxidant which easily causes sensitizing skin injury.

The kitchen detergent according to the present invention is not found in conventional detergents of the same kind in that in addition to the detergent and degreasing effect, the essential effects on the skin of the above five items can be expected, but exhibits extremely excellent effects. can do.
