Description

Kitchen detergent composition {DETERGENT COMPOSITION FOR DISHWASHING}

The present invention relates to a kitchen detergent composition.

Kitchen detergent is an aqueous solution in which an active ingredient, commonly referred to as a surfactant, and an additive such as a skin protectant are mixed. In kitchen detergents, active ingredients refer to surfactants that can contribute to a cleaning effect, and include nonionic and zwitterionic surfactants and mixtures of these surfactants. Additives in kitchen detergents consist of skin protection ingredients, solubilizers, and fragrances that reduce skin irritation from active ingredients. The skin protection component collectively refers to substances that inhibit dehydration and deoiling of the skin by active ingredients of detergents or supply effects to the skin by moisturizing and retaining. These detergents are usually used in a transparent liquid form to remove food residues adhered to hard surfaces such as tableware and cooking utensils, and are used after being diluted to a standard amount at a temperature of 20 to 45 ° C.

A surfactant is a substance that is activated at the interface where substances of different properties meet. Water and oil do not mix because water is polar and oil is non-polar. In general, polar molecules mix well with polar molecules, and non-polar molecules mix well with non-polar molecules. Surfactant basically appears in a molecule in which a polar part and a non-polar part exist together in one molecule. That is, a component having both a hydrophilic part that likes water and a hydrophobic part that hates water in one molecule can be used as a surfactant. Substances commonly referred to as oil are immiscible with water and have opposite properties in terms of solubility, so the hydrophobic portion that hates water simultaneously shows the property of being lipophilic that likes oil and the hydrophilic that likes water. The part will show the lipophobic property that hates oil. In the case of general surfactants, a long chain of carbon atoms constitutes the hydrophobic part, and since the size of the polar hydrophilic part is significantly smaller than the hydrophobic part, the hydrophilic part is called the head, and the long hydrophobic chain part is the tail. (tail) is called.

Surfactants are commonly used to classify according to the structure and properties of the head. Surfactants with anion in the head part that interacts with water are classified as anionic surfactants, and if the hydrophilic head part has cations, they are classified as cationic surfactants. It can be classified into a type of surfactant, a zwitterionic (amphoteric) surfactant having a polarity but containing a neutral part, and the like. There are also nonionic surfactants that do not have anions or cations in their hydrophilic head.

Among the products that use surfactants, detergents are the most commonly seen. If you wash tableware containing food with oil only with water, oil stains remain, but if you use kitchen detergent, oil stains are completely removed because of the role of surfactant. The hydrophobic tail of the surfactant interacts with the oil stain, and the head of the surfactant surrounding the oil stain interacts so that the grease-surfactant aggregates can be dissolved in water so that the oil is washed away by the water.

Anionic surfactants include sulfate ester salts, sulfonic acid salts, carboxylate salts, and phosphoric acid ester salts, which are usually neutralized with sodium or potassium ammonium amine. Anionic surfactants enhance cleaning power and have excellent foaming properties. Among anionic surfactants, there are many sodium lauryl sulfate (SLS), a type of sulfate ester salt, sodium laureth sulfate (SLES), a type of AES, and aluminum lauryl sulfate (ALS), a type of AS, which destroy the skin barrier. There is a problem. In addition, there is a possibility of causing liver or kidney disease and allergies due to inhalation or contact. Anionic surfactants generate bubbles when mixed with drainage, and the bubbles generated in this way make it difficult for various organisms to breathe and block sunlight and oxygen supply, thereby reducing the purification ability of water quality and increasing water pollution. Sodium lauryl sulfate (SLS) has a very strong detergency, but it irritates the skin, eyes, respiratory system, etc., and is not discharged from the body, and there is a remaining problem.

It is already known that nonionic surfactants and amino acid surfactants are used as representative examples of mild surfactants. In particular, alkyl polyglucosides, which are nonionic surfactants, are widely used because they use plant-derived ingredients for both hydrophobic and hydrophilic parts, and thus have environmentally friendly advantages and are advantageous in terms of skin drying and skin irritation. However, alkyl polyglucosides have a disadvantage in that their foaming power, which is a basic property of detergents, is rather low, because the hydrophilicity of polymerized glucose is not so strong compared to anionic surfactants.
