Abstract

PURPOSE:To realize the formation of a kitchen detergent which has sufficient detergency and degreasing ability, and can prevent injury of the skin and normalize the function of the skin, by incorporating a ferromagnetic salt into a kitchen detergent. CONSTITUTION:This kitchen detergent contains a ferromagnetic salt, which is either an inorganic salt, such as the chloride, sulfate phosphate or nitrate of iron, or an organic salt, such as the formate, acetate or propionate of iron, and which has intermediate properties between a ferrous salt and a ferric salt. An example of an especially desirable salt is Fe2Cl5.XH2O. It is desirable that, depending upon the properties of the detergent and the types of the ingredients, the ferromagnetic salt may be incorporated alone into the detergent, or may be used by incorporating it into a carrier comprising either an inorganic substance, such as sodium sulfate, diatomaceous earth or bentonite, or an organic substance, such as vegetable fiber, protein or lipid. The amount of the salt including the carrier is about 10<-5> to 10<-15>g for 100g of the detergent.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a kitchen detergent for cleaning vegetables, fruits, tableware, and cooking utensils.

[Conventional technology]

With the diversification and rationalization of living environments, the need for this type of kitchen detergent in terms of both quality and quantity has increased, and a wide variety of detergents are now commercially available.

That is, due to the Westernization of dietary habits and the trend towards high nutritional value, diets that are mainly composed of fat and protein have led to serious oil stains on tableware and cooking utensils.

Additionally, due to the need to remove residual pesticides associated with the consumption of fresh vegetables and fruits, there is a growing demand for kitchen detergents with stronger detergent and degreasing power.

However, on the other hand, it is also true that cases of damage in the field of dermatology, where household detergents are thought to be the main cause, are rapidly increasing. According to the 1985 "Hospital Monitor Report on Health Hazards Related to Household Products," which was compiled based on reports from dermatology monitor hospitals commissioned by the Ministry of Health and Welfare's Household Products Safety Measures Office, among patients who first visited a dermatology outpatient clinic, A total of 464 cases of health damage presumed to be related to household products were reported in one year, of which 156 were caused by household detergents, accounting for approximately 34 cases of the total. In particular, we cannot overlook the fact that progressive palmar keratoses accounted for the majority of cases in this case. It has been reported that the number of complete cures for this symptom is relatively small because it takes a long time to treat and patients are unable to leave their daily work with water, which prevents the symptoms from improving.

Furthermore, cases of damage such as contact dermatitis due to the use of rubber and vinyl gloves, which are used to avoid this condition, are increasing.

[Problem to be solved by the invention]

In view of the above-mentioned circumstances, there is a desire to develop a kitchen detergent that fully satisfies the original purpose of detergents, namely cleaning and degreasing power, and that does not damage the skin of fingers and palms.

The main functional components of human skin tissue are strong keratinized cells, a sebum membrane consisting of a sebum membrane secreted on the epidermal surface,
Also, the water retention capacity is increased due to the natural moisturizing factors present in the epidermal layer.

However, detergent ingredients with strong cleaning and degreasing properties partially break down the keratin that has this protective function, causing the sebum film and natural moisturizing factors to be washed away, resulting in dryness and advanced keratinization of the epidermis. Repetition causes progressive palmar keratoses.

The main purpose of kitchen detergents is to remove oils, fats, and protein components, so while there are many products that are satisfactory in terms of cleaning performance, there are no products that are satisfactory in terms of protecting the skin and preventing damage. At present, the type and amount of surfactant used is varied to create a composition that does not damage the skin as much as possible.

The kitchen detergents currently on the market are divided into the following three types: Type 2 vegetable-based synthetic detergent, Type 3 petroleum-based synthetic detergent.The cleaning performance increases in the order of 1 → 3, but the skin damage due to degreasing effects also increases in the same order. It gets intense. Although there are few complaints about skin damage with soap type 1, it seems that dissatisfaction with the cleansing power, which is the original purpose, cannot be avoided.

[Means to solve the problem]

The present invention has been intensively researched and developed in view of the above-mentioned circumstances, and has been developed to provide satisfactory cleaning and degreasing power, which is the original purpose of kitchen detergents, and to improve the skin's natural properties. The purpose of this invention is to provide a kitchen detergent that can maintain and restore normal physiological functions such as defense, respiratory, and secretory functions.

That is, the present invention relates to a kitchen detergent characterized by containing a divalent and trivalent iron salt having the above-mentioned purpose.

[Action of the invention]

When certain divalent and trivalent iron salts are dissolved in water or attached to water-containing surfaces such as the skin surface, they suppress various ionic reactions and induce reactions that are significantly different from those in normal aqueous systems. It seems that It has been found that by using such a kitchen detergent containing divalent and trivalent iron salts, it is possible to prevent skin damage caused by the detergent and restore the skin to its normal state.

[Embodiments of the invention]

The present invention will be explained in detail below.

The divalent and trivalent iron salts used in the kitchen detergent of the present invention include inorganic salts such as iron hydrochloride, sulfate, phosphate, and nitrate, and formates, which exhibit intermediate properties between divalent iron and trivalent iron. Organic salts such as acetate and propionate. For example, there are known complex salts of Fe5C17.xH2O1Fe3cI18.xH2O of divalent iron and trivalent iron. Showa 59
-190226 and JP-A No. 60-186581, Fe2CA'5. Depending on the type, not only the above divalent and trivalent iron salts may be blended alone, but also sodium chloride,
It is preferable to use an inorganic substance such as sodium sulfate, magnesium chloride, diatomaceous earth, bentonite, silica, alumina, or an organic substance such as vegetable fiber, protein, or lipid as a carrier to support the divalent and trivalent iron salt.

The blending amount of the divalent and trivalent iron salt, including the carrier, is 10 to 10 g per 1 oof detergent, preferably 10 to 10 g.
f range. If the amount added is greater or less than this range, the effect of the divalent and trivalent iron salt will be weakened. The pH of the detergent used can range from 3 to 11, but
~8 is the most preferred pH range.

In the kitchen detergent of the present invention, solvents, oils and fats, surfactants, preservatives, fragrances, pigments, etc. that are blended in ordinary detergents can be used without any problem, but the amount of divalent and trivalent iron salts blended is Since the amount of ions is extremely small, some chelating agents, phenols, mercaptans, cationic activators, etc. that are reactive with iron salts may contain them as raw materials or as mixed impurities. It may inhibit the effects of trivalent iron salts, so thorough checks must be made in advance.

There are many methods to check the effects of the divalent and trivalent iron salts of the present invention, such as the bioaccess method, but the following method is the simplest method.

When you add an appropriate amount of reagent copper powder to a sample of detergent as it is or diluted appropriately and disperse it, and then add a nitric acid test solution, in the case of a normal detergent, the copper powder and nitric acid naturally react and H2 gas is generated. The liquid takes on a blue color due to the formation of steel nitrate, but in the case of the detergent of the present invention containing divalent and trivalent iron salts, the liquid does not change color and no H2 gas is observed to be generated. This is thought to be because the dissolution of the copper powder and the ionic reaction are hindered by the divalent and trivalent iron salt. It is also possible to test the compatibility of compounded raw materials with divalent and trivalent iron salts in a similar manner.

By the above method, it is possible to obtain a kitchen detergent that has a function similar to that of a nonionic reaction system on the normal skin surface.

〔Effect of the invention〕

As described above, the kitchen detergent containing divalent and trivalent iron salts of the present invention has the following effects by preventing skin damage caused by detergents and normalizing skin functions.

(1) Enhancement of physiological functions of the skin The physiological functions of the skin tissues, such as the normal keratinization and metabolism of the stratum corneum, and the control of the sebum film by normalizing sebum secretion and water evaporation. It can promote normalization of function.

(2) Enhanced regenerative ability Skin tissue originally has the ability to normalize and recover from abnormalities on the skin surface due to metabolic dysfunction, damage to the stratum corneum caused by the external environment, and abnormalities in sebum and moisture levels. However, by using the detergent of the present invention, this regeneration function can be strengthened and recovered more quickly. for example,
It is possible to quickly normalize hyperkeratin abnormalities such as progressive digital palmar keratosis, remove stains due to pigmentation, and recover epidermal abnormalities caused by lack of sebum film such as cracks and redness.

(3) Enhancement of adaptability to environmental changes The adaptability of the skin to external stimulants, cold, heat, and exposure to ultraviolet rays can be strengthened to maintain the skin's natural defense function. For example, sensitizing skin damage can be prevented by inhibiting the invasion of antigenic substances from the outside, and skin can be maintained in a beautiful state by controlling the formation of skin membranes according to the environment.

(4) Inhibition of abnormal growth of microorganisms Skin troubles such as inflammation and suppuration due to abnormal growth of microorganisms from the outside and bacteria resident on the skin can be removed and prevented. In addition, the addition of divalent and trivalent iron salts eliminates the need for preservatives that are normally added, and prevents sensitizing skin disorders caused by preservatives.

(5) Inhibition of harmful ion reactions Skin aging can be prevented by inhibiting harmful ion reactions and free radical reactions, such as skin irritation reactions caused by external chemicals and the formation of lipid peroxides caused by ultraviolet rays. The combination of trivalent iron salts prevents oxidative deterioration of the detergent, making it unnecessary to use antioxidants that cause sensitizing skin disorders and are easily caustic.

The kitchen detergent according to the present invention has effects other than cleaning and degreasing.
In terms of the above five essential effects on the skin, it can exhibit excellent effects that cannot be seen in conventional detergents of the same type.
