Description

[0001] Liquid detergent composition [0002]

The present invention relates to a structured liquid detergent composition, and more particularly, to a liquid detergent composition having transparent and high viscosity, and having excellent washing power against sebum, oil, and food contamination through improved enzyme stability and excellent in phase stability. It is about.

There are various reasons for structuring liquid detergents with high viscosity. If the structure of the liquid in the water system has the advantage that can be stabilized by dispersing the particles insoluble in water, but there is a problem that it is difficult to stabilize a material that is soluble in water or a material that is not stable in water. And it has an opaque appearance as various materials enter to structure the liquid.

However, structuring with polymers with high viscosity in non-aqueous systems can improve the stability and dispersibility of particles or capsules that are not soluble in water, and can also enhance the stability of enzymes. It can show high cleaning power. And it can be structured into a transparent phase to give it an aesthetic effect.

The enzyme is an auxiliary washing component of the laundry detergent, but its function is very good, but it is easily denatured by the surfactant and various ionic substances in the liquid laundry detergent, or decomposes itself and loses its activity. Conventional methods used for the stabilization of enzymes in liquid detergent compositions include calcium salt formulations, short chain carboxylic acid salt combinations, polyols and boric acid or derivatives thereof, methacrylic acid / methacrylic acid ester copolymers and polyethylene glycols that produce free calcium ions. Stabilization by mix | blending these, etc. are mentioned. However, the conventional technique as described above has a problem that the degree of enzyme stabilization is not high. In order to solve this problem, Korean Patent 2004-0008986 proposes a method of combining an boron compound having an aryl group with an enzyme stabilizer composed of formic acid, boric acid, and salts thereof, and in Japanese Patent 2009-297225, a specific carboxylic acid or It is proposed that the enzyme stability can be improved by first mixing the salt with the enzyme and water and then mixing the surfactant. However, the conventional technique proposed in the above patent is also not a sufficient method for enhancing the enzyme stability.

In addition, US Patent 5580849 A discloses that it is non-aqueous, contains anionic and nonionic surfactants, and contains calcium ions and strotium ions, thereby improving the stability of the liquid detergent and improving the decontamination ability. The particles of sulfate crystals containing anionic surfactants, which are easily soluble in water by increasing the viscosity of the formulation by inorganic salts, were insoluble in water so as to ensure the stability of the particles. U.S. Patent 6369018 B1 also uses additive cross-linked polycarboxylic polymers, gums, as the main additives mentioned for structuring the liquid phase, using water and a sufficiently pre-expansion process to remove the liquid from the water phase before using these polymers. A method of structuring is disclosed.

However, in the non-aqueous phase, the composition containing the anionic surfactant has a high viscosity by using an inorganic salt or a polymer, and the structured liquid detergent can ensure the stability of the particles dissolved in water, but only the nonionic surfactant without ionicity Increasing the viscosity in the included composition has a problem in that the effect is less effective in securing the stability of the particles. In addition, methods for structuring liquids in water using polycarboxylic polymers or gum-based polymers have been generally used. When structuring liquids in water, there is a problem in that materials having low stability in water cannot be used.

Therefore, in a non-aqueous system containing no water or using a very small amount of water, it can be said that a liquid detergent composition technology capable of structuring while improving the stability of the enzyme without impairing the stability and improving the stability of the enzyme is required.

An object of the present invention to solve the above problems is possible with a structured liquid detergent composition having a transparent and high viscosity without using water or low water content without using an ionic surfactant, excellent phase stability It is to provide a structured liquid detergent composition characterized in that the phase separation does not occur and also has an excellent cleaning power against sebum contamination, oil contamination, food contamination through improved enzyme stability.

According to the present invention,

a) 10 to 50% by weight of the nonionic surfactant represented by the formula (1);

b) 0.1 to 5% by weight of acrylate polymer; And

c) 45-85 wt% solvent

It relates to a liquid detergent composition comprising a.

[Formula 1]

R ₁ -O- (EO) xH

(In Formula 1, R ₁ is a linear or branched alkyl or alkenyl group having 9 to 16 carbon atoms, EO is an oxyethylene group, and x represents an average added mole number of ethylene oxide.

The liquid detergent composition according to the present invention is a structured liquid detergent composition which is transparent and has high viscosity and very excellent phase stability even when it does not contain water or contains an extremely small amount by using a nonionic surfactant and an acrylate polymer. Enzyme stability is improved to have high cleaning power against various contaminations.

The inventors of the present invention prescribe acrylate polymers in a composition containing a non-ionic surfactant, a solvent and little water during the study of the liquid detergent composition, has a transparent phase while having excellent storage stability at low and high temperatures We have developed a liquid detergent composition that is structured, has excellent washing power through improved enzyme stability, and excellent dispersibility in water.

The present invention

a) 10 to 50% by weight of the nonionic surfactant represented by the formula (1);

b) 0.1 to 5% by weight of acrylate polymer; And

c) 45-85 wt% solvent;

It provides a liquid detergent composition comprising a.

[Formula 1]

R ₁ -O- (EO) xH

(In Formula 1, R ₁ is a linear or branched alkyl group or alkenyl group having 9 to 16 carbon atoms, EO is an oxyethylene group, and x represents an average added mole number of ethylene oxide, which is 5 to 15.)

In general, liquid detergents mostly contain nonionic surfactants, and since they do not contain anionic surfactants and have high viscosity and are difficult to structure, many raw materials for increasing the viscosity are used. In order to compensate for this problem, ionic and nonionic surfactants are mixed to maintain high surfactant content. In this case, inorganic salts and polymers are used to structure or increase the viscosity. The use of a high surfactant content and a large amount of the polymer has a problem that the cost increases, and generally, the phase of the liquid structured with the surfactant is opaque and ineffective in terms of aesthetics. In addition, there is a method of structuring at a low surfactant content by using a gum-based polymer, but there is a problem that can be used only when swelling in water.

In the present invention, by using the acrylate-based polymer in a composition containing little water in the non-ionic surfactant, the present invention can be transparent and structured even with a small amount of surfactant, and the washing power is improved by improving the stability of the enzyme. The synergistic effect can be given.

Washing power, phase stability, physical properties, turbidity, protease stability, and stability of enzymes other than proteases of the liquid detergent compositions prepared according to Examples and Comparative Examples were measured as follows.

<Experimental Example>

 1) Evaluation of cleaning power

The washing rate was measured at 25 ° C with a rotating RPM of 120, and the amount of the sample was 1 g of water in 1 L of water. The washing time was 10 minutes, and the rinsing was carried out twice for 3 minutes each.
