Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a detergent composition that is mild to the skin, has an excellent feeling of use, and has high foaming power.

Conventional technologies and drawbacks In recent years, the safety requirements for various cleaning agents have been increasing, and the development of new highly safe surfactants is required, and among the conventionally used surfactants, Highly safe products are being reconsidered, and demand for products containing these ingredients is gradually increasing.

N-acyl amino acid salt type surfactants, alkyl alkyl taurine salt type surfactants, and phosphate ester type surfactants are detergents that have mild effects on the skin and hair, and are used as solid detergents, hair shampoos, and body shampoos. It is used for such things.

The above-mentioned alkyl alkyl taurine salt type surfactants are biogenic amine derivatives and are relatively mild to the skin, so they are used as bases for skin and hair cleansers such as shampoos, body shampoos, and facial cleansing foams. However, there is a drawback that the skin tends to feel slimy when rinsing after washing.

In addition, mono- and dialkyl phosphate ester surfactants are easy to rinse and are gentle on the skin when used as skin cleansers, but they lack hard water resistance and tend to cause squeaks on the skin and hair after washing, giving them a luxurious appearance. It had the disadvantage of being too expensive. Furthermore, N-acyl amino acid salt type surfactants have a very mild action on the skin and hair, are pleasant to use, and give a moist feeling to the skin and hair after washing, but they have the disadvantage of being low in foaming. Another drawback is that a slimy feeling tends to remain on the skin after rinsing.

In the combination of the above surfactants,
An example of using an alkylyl alkyl taurine salt type surfactant and a phosphate ester type surfactant in combination in 078, and a combination of an N-acylamino acid salt type surfactant and a phosphate ester type surfactant in JP-A-54-120610. There is an example. However, in combinations of alkyloyl alkyl taurine salt-type opening surfactants and phosphate ester-based surfactants, hard water resistance is low in systems containing a large amount of phosphate esters with a large amount of foaming; Combinations of surfactants and N-acylamino acid salts have problems such as difficulty in thickening.

Problems to be Solved by the Invention The problem to be solved by the present invention is to solve the above-mentioned drawbacks, and to provide hard water resistance.
To develop a detergent composition that does not give a slimy feeling or squeak sensation and leaves the skin moist after washing.

Means for Solving the Problems In order to solve the above-mentioned problems, the present inventors investigated the combined effect of various surfactants, and as a result, they have developed a novel cleaning agent useful as a cleaning composition. We have arrived at inventing a composition.

That is, the present invention is a novel detergent composition, which makes it possible to impart a good range of use and safety to detergent compositions including hair shampoos, body jumps, and bar soaps, and (a) Contains an alkyloyl alkyl taurine salt type surfactant, (b) a phosphate ester type surfactant, and (c) an N-acylamino acid salt type surfactant as essential components, and (a), (b), and (c) The mixing ratio of (
a): (b) = 50: 1 to 65: 35 and total amount of (a) and (b) + (c) = 5: 1 to 1

Moreover, this cleaning composition may contain 0.1 to 8% of common salt.

The alkyloyl alkyl taurine salt type surfactant used here is N-alkyloyl-N-alkyl taurine having 8 to 22 carbon atoms in the side chain, metal salts such as sodium, potassium, and calcium, and triethanolamine, Phosphate surfactants may also be organic weak base salts such as arginine, lysine, choline, etc. Phosphate surfactants also refer to mono-, di-, and trialkyl phosphate surfactants having 8 to 22 carbon atoms in their side chains. Referring to the entire active agent, phosphoric acid ester surfactants may have 1 to 20 moles of ethylene oxide added, and mono- and di-based surfactants include unneutralized acid types and sodium, potassium, calcium, etc. metals and triethanolamine, arginine,
It may also be a salt with a weak base such as lysine or choline.
Furthermore, the term "N-acyl amino acid salt type surfactant" refers to all N-acyl amino acids having 8 to 22 carbon atoms in the side chain and their salts, and N-acylated products of acidic amino acids such as N-acyl glutamic acid and their salts. , N-acylated products of neutral amino acids such as N-acyl-N-methylglycine, N-acyl-β-alanine and their salts, N- of basic amino acids such as N-acyl-arginine, N-acyl-lysine, etc.
It refers to all N-acylated products of amino acids and their salts, including acidic, neutral, and basic amino acids, such as acylated products and their salts, and N-acylamino acids refer to salts of metals such as sodium, potassium, and calcium. Organic weak base salts such as triethanolamine, arginine, lysine, and choline may also be used.

In addition to the above-mentioned essential ingredients, the cleaning composition of the present invention may contain ingredients commonly added to cleaning agents, such as higher alcohols, castor oil derivatives, fatty acid derivatives of polyethylene glycol, lanolin derivatives, and squalane. Oily components such as derivatives and other hydrocarbons, amino acids and their derivatives, propylene glycol, glycerin, 1.3

Further, by adding a small amount of common salt to the cleaning composition of the present invention, a viscosity suitable for the intended use can be obtained.

Effect of the invention That is, the present invention is a novel and useful cleaning composition.

It provides a cleansing agent with a moisturizing effect on the skin and hair after washing, yet does not have a slimy feel, and also produces a large amount of foam during washing, making it easy to use, less aggressive, and highly resistant to hard water. This is an effective cleaning composition. In addition, the salt makes it possible to obtain a suitable viscosity for a liquid cleaning agent. It can be used in various forms such as solid, kneaded, and liquid, but regardless of the form, it fully exhibits the effects described above.

In the cleaning composition of the present invention, excellent effects are observed when the ratio of the alkyl alkyl taurine salt type surfactant to the phosphate ester type surfactant is around 50:] to 65:35. Further, excellent effects are observed when the ratio of the total amount of the alkyloyl alkyl taurine salt type surfactant and the phosphate ester type surfactant to the N-acylamino acid is 5:1 to 1:5.
