JP5273836B2 - Cleaning composition - Google Patents

Description

  The present invention relates to a cleaning composition having an excellent conditioning effect, a sufficient foaming power, and an appropriate viscosity.

  Detergents are required to have detergency and good foaming. At the same time, in recent years, consumers' awareness of care has increased, and in addition to basic performance as a cleaning agent, there is a tendency to require a feeling of use during cleaning, a good feeling after finishing, and a conditioning effect.

  Conventionally, as a conditioning agent for a cleaning agent, a cationized polymer, a high molecular silicone, a protein, an amino acid, or the like is blended (see, for example, Patent Documents 1 to 3). However, it is not yet satisfactory in terms of the feeling of use and finish during washing. In addition, anionic surfactants such as α-olefin sulfonate, sodium lauryl sulfate, and polyoxyethylene sodium lauryl ether sulfate are used as highly foaming detergents. These detergents have a conditioning effect. Therefore, it was not possible to obtain a preferable feeling during washing. Amino acid surfactants such as acyl sarcosine salts, acylmethyl-β-alanine salts, and acyl glutamine salts are used as mild detergents (see, for example, Patent Documents 1 and 4). However, when a high concentration is added to the cleaning agent, the viscosity is difficult to be obtained, and even if the viscosity can be temporarily obtained, the viscosity becomes lower with the lapse of time.

Japanese Patent No. 3064037 JP-A 63-45213 JP 2000-319140 A Japanese Patent No. 3644466

  In the above circumstances, a technique for eliminating the above-described drawbacks has been demanded. That is, an object of the present invention is to provide a detergent composition having an excellent conditioning effect, a sufficient foaming power, and an appropriate viscosity.

As a result of intensive studies in view of the above circumstances, the present inventor has found that a detergent composition containing a specific surfactant, a cationic polymer, and an inorganic salt can achieve the above object, and has completed the present invention. . That is, the present invention includes (A) N-acyl sarcosine triethanolamine, (B) polyoxyethylene lauryl ether sulfate triethanolamine, (C) polyoxypropylene fatty acid isopropanolamide, (D) cationic polymer, (E) A hair cleansing composition containing a water-soluble inorganic salt and (F) an amphoteric surfactant.

  ADVANTAGE OF THE INVENTION By this invention, the cleaning composition which is excellent in a conditioning effect, has sufficient foaming power, and has moderate viscosity can be provided.

Examples of (A) N-acyl sarcosine triethanolamine used in the present invention include N-lauroyl sarcosine triethanolamine and N-myristoyl sarcosine triethanolamine. The blending amount of N-acyl sarcosine triethanolamine is preferably 1.0% to 30.0% by mass (hereinafter simply referred to as%), more preferably 5.0 to 20.0%, based on the entire composition. It is. This is because when the blending amount of N-acyl sarcosine triethanolamine is increased, the conditioning effect (for example, the feeling of use during washing and the feeling of finishing after washing, etc.) is increased, but the viscosity is lowered. This is because 1.0% or more is preferable for obtaining the conditioning effect, and 30.0% or less is preferable for maintaining a suitable viscosity and obtaining sufficient foamability.

  The blending amount of (B) polyoxyethylene lauryl ether sulfate triethanolamine used in the present invention is not particularly limited, but is preferably 0.1 to 5.0%, more preferably based on the entire composition. 0.5 to 3.0%. This is because when the blending amount of polyoxyethylene lauryl ether sulfate triethanolamine is increased, the viscosity is increased, but since the conditioning effect tends to be inhibited, 0.1% or more is preferable to maintain an appropriate viscosity. This is because 5.0% or less is preferable in order to obtain a sufficient conditioning effect.

  Examples of (C) polyoxypropylene fatty acid isopropanolamide used in the present invention include polyoxypropylene lauric acid isopropanolamide, polyoxypropylene myristic acid isopropanolamide, polyoxypropylene stearic acid isopropanolamide, and polyoxypropylene coconut oil fatty acid isopropanol. Amide, polyoxypropylene palm kernel oil fatty acid isopropanolamide and the like. Although a compounding quantity is not specifically limited, 0.5-15.0% is preferable with respect to the whole composition, More preferably, it is 1.0-5.0%. This is because increasing the compounding amount of polyoxypropylene fatty acid isopropanolamide increases the viscosity, but if the viscosity becomes too high, it tends to inhibit foaming. This is because 0.5% or more is preferable to obtain the viscosity, and 15.0% or less is preferable to obtain a viscosity that does not inhibit foaming properties.

  The cationic polymer (D) used in the present invention is not particularly limited, but examples thereof include cationized cellulose derivatives, cationic starches, cationized guar gum derivatives, diallyl quaternary ammonium salt polymers, diallyl 4 A quaternary ammonium salt / acrylamide copolymer, a quaternary polyvinyl pyrrolidone derivative, and the like. These cationic polymers can be appropriately selected, and one or more can be used. Although the compounding quantity of these cationic polymers is not specifically limited, 0.1 to 3.0% is preferable with respect to the whole composition, More preferably, it is 0.3 to 1.5%. This is because if the amount of the cationic polymer is increased, the conditioning effect is enhanced, but if it is increased too much, it tends to precipitate in the cleaning liquid, so 0.1% or more is preferable to obtain a sufficient conditioning effect. This is because 3.0% or less is preferable for solubilization without precipitation in the cleaning agent.

  The water-soluble inorganic salt (E) used in the present invention includes a monovalent cation composed of sodium ion, potassium ion and ammonium ion and / or a divalent cation composed of magnesium ion and calcium ion, chlorine ion and sulfuric acid. It is at least one salt formed from an anion consisting of ions, phosphate ions, carbonate ions and nitrate ions. Preferred examples include sodium chloride, sodium carbonate, sodium sulfate, sodium hydrogen sulfate, sodium phosphate, sodium hydrogen phosphate, potassium chloride, potassium sulfate, potassium hydrogen sulfate, potassium phosphate, potassium hydrogen phosphate, diphosphate phosphate. Examples include potassium hydrogen, magnesium chloride, calcium chloride, ammonium sulfate, ammonium phosphate, magnesium sulfate, and sodium chloride, magnesium chloride, calcium chloride, and magnesium sulfate are more preferable. Although the compounding quantity of these water-soluble inorganic salts is not specifically limited, 0.1 to 3.0% is preferable with respect to the whole composition, More preferably, it is 0.3 to 1.5%. This is because when the blending amount of the water-soluble inorganic salt is increased, the viscosity is increased, but conversely, when the amount is excessively increased, the viscosity is decreased. Therefore, 0.1% to 3.0% is preferable for an appropriate viscosity. It is.

  The amphoteric surfactant (F) used in the present invention is not particularly limited, and examples thereof include laurylbedine, lauroylamidopropylbedine, 2-alkyl-N-carboxymethyl-N-hydroxyethylimidazolinium. Mbedine and the like. These amphoteric surfactants can be appropriately selected, and one or more can be used. Although the compounding quantity of these amphoteric surfactants is not specifically limited, 1.0 to 10.0% is preferable with respect to the whole composition, More preferably, it is 3.0 to 8.0%. This is because if the amount of amphoteric surfactant is increased, the conditioning effect increases and the viscosity also increases.However, if the viscosity is too high, the conditioning effect and foaming tendency tend to be inhibited, so a sufficient conditioning effect is obtained. This is because 1.0% or more is preferable for obtaining, and 10.0% or less is preferable for maintaining an appropriate viscosity.

  In addition to the components described above, the components that are usually used in the cleaning composition can be appropriately blended with the cleaning composition of the present invention within the range achieved by the present invention. Examples of these components include nonionic surfactants, cationic surfactants, moisturizers, silicone derivatives, oils, plant extract extracts, viscosity modifiers, pearling agents, drugs, preservatives, chelating agents, antioxidants, PH adjusters, pigments, fragrances and the like can be mentioned.

  The cleaning composition of the present invention can be used for hair shampoos, body shampoos, hand soaps, facial cleansers, etc., regardless of the subject or dosage form. These can be produced by blending the cleaning composition of the present invention in a conventional manner.

  The present invention will be described in detail based on examples, but the present invention is not limited thereto. Prior to the examples, test methods and evaluation methods employed in each example will be described.
