Abstract

PURPOSE: To obtain a nongas foamer compsn. which produces creamy foams and hardly cause clogging in a pump by incorporating an N-long-chain acyl-α- amino acid or one or more kinds of its salt. CONSTITUTION: This non-gas foamer compsn. contains an N-long-chain acyl-α- amino acid or one or more kinds of its salt. This non-gas foamer compsn. can be used for various purposes as detergents such as kitchen detergent, shampoo, face cleaner, body cleaner, and bubble bath detergent, or cosmetics such as shaving foam and hair setting foam. Moreover, a surfactant other than the N-long-chain acyl-α-amino acid or its salts can be added to this non-gas foamer compsn. as far as the effect of the compsn. is not decreased. Or, if necessary, besides the essential component, humectant, higher alcohol, ester and the like can be added as far as the effect or the compsn. is not decreased.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION This invention relates to non-gas former compositions capable of producing creamy foams without the use of propellants, and more particularly to creamy foams and pump clogging. The present invention relates to a composition for a non-gas former which hardly causes

[0002]

2. Description of the Related Art Conventionally, an aerosol can has been widely used as a convenient container for ejecting a foaming liquid containing a surface-active agent such as a facial cleanser and a hair setting agent into a creamy foam.
However, since this aerosol can uses liquefied gas such as liquefied propane as a propellant, it is subject to regulations regarding volatile organic compounds, and it is not possible to reuse used cans. was there.

On the other hand, in recent years, a non-gas former which is a container capable of producing creamy foam by utilizing air pressure without using a propellant has come to be used (food and container, Volume 34, No.8, Page 467, Same Volume, No.9, 5
31). However, the quality of bubbles produced by the non-gas former is inferior in creamyness to the bubbles produced by an aerosol can, and there are problems that pump clogging is likely to occur.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a non-gas former composition which produces creamy foam and is less likely to cause pump clogging.

[0005]

The inventors of the present invention have conducted extensive studies to solve the above-mentioned problems, and as a result, the N-long-chain acyl-α-amino acid or its salt was found to be a surfactant for non-gas formers. As a result, it was found that creamy foam is obtained, and pump clogging is less likely to occur.
The present invention has been completed.

That is, the present invention relates to N-long chain acyl-α
-A non-gas former composition comprising one or more amino acids or salts thereof.

The present invention will be described in detail below. Examples of the long-chain acyl group in the N-long-chain acyl-α-amino acid or salt thereof used in the present invention include octanoyl, decanoyl, lauroyl, myristoyl, palmitoyl, stearoyl, oleoyl, linoleoyl, coconut oil fatty acid acyl, palm kernel oil. Examples thereof include a fatty acid acyl group. Particularly, a coconut oil fatty acid acyl group and a palm kernel oil fatty acid acyl group are preferable from the viewpoint of solubility. As the α-amino acid,
Examples thereof include α-neutral amino acids such as glycine, alanine, valine, leucine, isoleucine, serine, threonine, phenylalanine, cysteine and methionine, and α-acidic amino acids such as aspartic acid and glutamic acid. The salt is not particularly limited, but examples thereof include alkali metal salts such as sodium and potassium, alkaline earth metal salts such as magnesium and calcium, triethanolamine, 2-amino-2-methyl-1-propanol, and 2 Examples thereof include alkanolamine salts such as -amino-2-methyl-1,3-propanediol, ammonia salts, choline salts and basic amino acid salts such as lysine, ornithine and arginine.

Such an N-long chain acyl-α-amino acid can be easily prepared by a known method, for example, by converting a fatty acid to a fatty acid chloride with phosphorus trichloride, thionyl chloride, phosgene, etc. and then adding it to an alkaline solution of the α-amino acid. It can be manufactured.

N-long chain acyl-α-used in the present invention
Preferred amino acids include lauroylglycine, cocoylglycine, myristoylglycine, lauroylalanine, cocoylalanine, myristoylalanine, lauroylglutamic acid, cocoylglutamic acid, myristoylglutamic acid, and the like, among which cocoylglycine potassium, cocoylglycine triethanolamine, Potassium cocoyl glutamate and triethanolamine cocoyl glutamate are preferable from the viewpoint of solubility.

The amount of the N-long chain acyl-α-amino acid or its salt to be added to the composition for non-gas former of the present invention is 1 to 40% by weight, preferably 2.5 to 20% by weight of the composition.
% By weight. The pH is preferably 5 to 10.5, although it varies depending on the type of the N-long chain acyl-α-amino acid or salt used, and is preferably 5.5 to 10 from the viewpoint of foamability and stability. Less than 5 or 1
If it exceeds 0.5, it is not preferable from the viewpoint of stability such as browning or turbidity during long-term storage.

Examples of the non-gas former container used in the present invention include a squeeze former capable of ejecting bubbles by manually squeezing the bottle body and a pump former capable of ejecting bubbles by pushing down the nozzle portion. In particular, a pump former is preferable because it can generate creamy foam. Such a pump former is commercially available from, for example, Yamato Seikan Co., Ltd.

The composition for a non-gas former according to the present invention may be used for a detergent such as a kitchen cleaner, shampoo, facial cleanser, body cleaner, bubble bath cleaner, shaving foam, hair setting agent, etc. depending on the purpose of use. Can be used for charges.

In the composition for a non-gas former of the present invention, a surfactant other than the above-mentioned N-long chain acyl-α-amino acid or a salt thereof can be used in combination within a range not impairing the effects of the present invention.

In the composition for a non-gas former of the present invention, in addition to the above essential components, if necessary, moisturizing agents such as ethylene glycol, propylene glycol, 1,3-butylene glycol, glycerin and sorbitol, and glyceryl monostea. Rate, sorbitan monopalmitate,
Emulsifiers such as polyoxyethylene cetyl ether, polyoxyethylene stearic acid ester, polyoxyethylene sorbitan monolaurate, diglycerin monostearic acid ester, liquid paraffin, petrolatum, solid paraffin, squalane, hydrocarbons such as olefin oligomers, stearyl alcohol Higher alcohols such as isopropyl myristate, isopropyl palmitate, stearyl stearate, octyldodecyl myristate,
Octyldodecyl oleate, esters such as 2-ethylhexanoic acid triglyceride, touch enhancers, superfatting agents, agents such as crude drugs, cellulose derivatives such as methyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, cationized cellulose, natural polymers, poly Oxyethylene glycol distearate ester, viscosity modifiers such as ethanol and carboxyvinyl polymer, antiseptic / antifungal agents such as paraben derivatives, pearlizing agents, anti-inflammatory agents, UV absorbers, pH adjusters, perfumes, pigments, etc. Common components used in cosmetics or cosmetics can be added within a range that does not impair the effects of the present invention.

EFFECTS OF THE INVENTION The present invention makes it possible to provide a cleaning agent, a cosmetic or the like using a non-gas former which has not been used so far because of problems such as foam quality and pump clogging.

[0016]

The present invention will be described in more detail with reference to specific examples. In addition, in this example, the compounding amount was represented by wt%.

Test Example 1 The surfactants shown in Table 1 were dissolved in purified water to a concentration of 10% by weight, and each solution was added to a pump former "C1-K" (manufactured by Yamato Seikan Co., Ltd.) in an appropriate amount. The creamy property of the foam and the pump clogging at the time of filling and actually using were evaluated according to the following criteria. Table 1 shows the results.

(A) Evaluation of foam creaminess The foam was discharged by pressing the pump once, and the appearance was evaluated. ◎: Uniform and fine ○: Some large bubbles are mixed △: Some large bubbles are mixed ×: Very many large bubbles

(B) Evaluation of pump clogging After pushing the pump 10 times to discharge bubbles, it was left at room temperature for one week and used again to evaluate the pump clogging. ○: Not clogged △: Slightly caught ×: Clogged
