Description

Composition for liquid detergents composed of only food-grade ingredients}

After the development of synthetic detergents around the 1st and 2nd World War, the development of advanced alcohol sulfate ester salt of Deutsche Hydrier Werke of Germany in 1928 began development of various surfactants such as ABS, LAS, AS, AES, AOS, and SAS. Due to advances in synthetic technology, the synthetic detergent industry is growing rapidly. As of 1994, domestic synthetic detergent production amounted to 280,000 tons, equivalent to about 400 billion won. In addition, dual kitchen cleaners have a market size of W85bn and continue to increase.

Due to the increase in the amount of synthetic detergents, various side effects occur to the human body and the environment, and the detergent industry in the world has better cleaning power and is harmless to humans in consideration of environmental and stability. We are focusing on developing biodegradable cleaners. In the 1960s, Germany, the United States, and the United Kingdom banned the use of poorly biodegradable branched chain ABS (sodium alkylbenzene sulfonate) in rivers, and replaced it with linear alkylbenzene sulfonate (LAS), which is highly biodegradable in water. In addition, the use of polyphosphate, which causes river eutrophication, is also prohibited, and has been used in Korea since 1988, since it has been replaced with zeolite and sodium citrate.

Recently, in the field of kitchen liquid detergents, according to the consumer's demand for developing eco-friendly detergents, the company has tried to limit the use of petroleum-based surfactants and make environmentally-friendly products with less irritation and quick biodegradation using raw materials extracted from plants. Competitive effort.

In general, kitchen liquid cleaners, which are commercially available for washing fruits, vegetables, and dishes, contain anionic surfactants as main ingredients, and include pH adjusting agents, flavoring agents, viscosity adjusting agents, microbial inhibitors, enzymes, opacifying agents, dyes and additional auxiliary surfactants. It is used together and solubilizers such as ethanol are used to dissolve high concentrations of ingredients and preserve them in the liquid phase.

It is widely commercialized and used as anionic surfactants, such as higher alcoholic sulfuric acid, salt salt type, alkyl sulfate, alkyl ether sulfate, and alpha olefin sulfonate. They are inexpensive, foamy, and have excellent cleaning power. It is used as the main raw material. However, due to the nature of the skin adsorption of the anionic surfactants are adsorbed by the skin irritating or invading the food directly by human ingestion is harmful to the human body.

In order to reduce the skin irritation by using vegetable raw materials such as palm oil and amine oxides, petroleum-based raw materials such as α-olefin are still used as main raw materials due to production and economical production of various manufacturers. Although amine oxides are used to protect the skin, they are only used to mitigate the harmful effects of raw materials that are harmful to the skin, and their limitations are still insufficient to meet the demands of consumers for the development of human-friendly and environmentally friendly cleaners. It can be said.

The main object of cleaning liquid for kitchen dish is vegetables, fruits, and utensils, which are used in direct contact with human body and food. It is contradictory by itself that harmful detergents are made safe for the human body. In addition, the remaining cleaning ingredients may harm the human body when inhaled through the mouth.

Therefore, many researches are being conducted to meet the requirements for developing a safe liquid detergent for kitchens that are safe for human body when inhaling into the human body through the mouth of environmentally friendly and remaining cleansing components of the consumer, excellent cleaning power, and safer for human body and environment.

As described above, commercially available anionic surfactant-based kitchen liquid cleaners are manufactured with a focus on economic efficiency and cleaning power, and are mainly made of anionic surfactants and use diethanol amide, amine oxide, etc. for skin protection. However, this is also used to alleviate the harmful effects of anionic surfactants that cause skin irritation, and the development of a dishwashing agent that is safe for the human body reveals its own limitations in terms of raw materials used.

Nonionic surfactants, on the other hand, have low skin irritation but poor cleaning and foaming power compared to anionic surfactants, and thus are mainly used as emulsifying and dispersing agents.

Accordingly, the present inventors developed a product using only food additive grade raw materials for kitchen liquid cleaners used in direct contact with food and the human body, thereby avoiding the use of raw materials harmful to the human body in terms of raw materials. The development of kitchen liquid cleaners, which does not harm the human body, is also inhaled against the ingestion of cleaning components and residues of dishes and food surface after washing.

In addition, by using 95% by weight or more of nonionic surfactants with low irritation to the skin, it eliminates disadvantages such as skin irritation of cleaning agents centered on anionic surfactants, and overcomes the limitations of cleaning and foaming power of nonionic surfactants. The cleaning power is excellent and safer cleaner has been developed.

The human body forms sebum for the protection of the human body, and the healthy sebaceous membrane pH of the human body is about 4.5-6.0. In general, the pH of synthetic detergents does not significantly affect the skin surface when it is temporarily contacted with alkali because it has the power to return to its original pH. Therefore, commercially available dishwashing detergents based on anionic surfactants have been added to the pH of about 7.0 by adding a pH adjuster separately.

But this is also not a good pH for the human body. Accordingly, the present invention has been developed a product having a pH of 4.5-6.0 by adjusting the pH only by adjusting the component content ratio of the raw material components without the addition of a separate pH regulator.

In addition, when the composition of the present invention is used as a baby bath detergent and baby product detergent, it does not adversely affect the infant during or after washing.

All of the compositions used for the present invention used only food additive grade raw materials.

As surfactants, nonionic surfactants account for more than 90% of the total surfactants, and saponins, monoglycerides, propylene glycol fatty acid esters, and sorbitan fatty acids can be used together with step or sucrose fatty acid esters. It has a cleaning power by blending the content of the nonionic surfactant is 10 to 40% by weight, preferably 15 to 30% by weight. Among saponins, quillaza extract was used, which has been recognized as an emulsifier and dispersant, and is widely used for various purposes such as raw materials for foodstuffs, cosmetics, and pharmaceuticals.

The nonionic surfactants have poor detergency and foaming power than anionic surfactants because of their characteristics. Sodium stearyl lactate was used to overcome the limitation of detergency and foaming power. 0.1 to 5% by weight of 15 to 30% by weight, preferably 0.3 to 3% by weight, improves the cleaning power and excellent foaming power. However, sodium stearyl lactate is insoluble in water and dissolves in maintaining an appropriate temperature. Therefore, caprylic acid is added at 0.1 to 2% by weight, preferably 0.3 to 1% by weight, at a temperature of 40 to 80 ° C. When heated and reacted, not only the low cleaning power and bubble power of the nonionic surfactants can be improved and improved, but also a clear and clear solution can be formed to obtain a clean appearance of the cleaner. Caprylic acid is also used for antimicrobial and product preservatives.

In addition, an appropriate viscosity is required to be used as a kitchen detergent. For this purpose, water-soluble chitosan was used instead of the synthetic polymer used in the fruit vegetable detergent and the kitchen detergent. The chitosan used herein used water-soluble chitosan that was not treated with acetic acid, unlike conventional chitosan. The function and efficacy of this water soluble chitosan is US patent APP. No 09 / 040,389, APP. No. 09 / 044,022, Korean Patent Nos. 99-0038650, 99-0038656, 99-0038657, etc., are not only used as health supplements in the food field, but also used as raw materials for the fields of medicine / medical materials, cosmetics, and the like. The water-soluble chitosan can maintain a preferable viscosity by containing 0.1 to 3 weight%, preferably 0.5 to 2 weight%.

As described above, the present invention not only improves and improves the low detergency, foaming power and viscosity of the nonionic surfactant through proper blending of the ingredients with 100% food additive grade ingredients but also commercially available anionic interfaces. Recognition of liquid detergents by eliminating skin damage caused by skin adsorption of active liquid detergents based on active agents, and developing safe detergents for humans against ingestion of small amounts of detergent residues that penetrate into food or remain on dishes and food surfaces after washing This will drive cleaner manufacturers to focus on developing more human-friendly cleaners that meet consumer needs.
