JP5837434B2 - Liquid cleaning material - Google Patents

Description

  The present invention relates to a liquid cleaning material. More specifically, the present invention relates to a liquid cleaning material suitably used for skin or hair.

  Cleaning agents are classified into surfactant-type cleaning agents and solvent-type cleaning agents, depending on the cleaning mechanism.

  A surfactant-type cleaning material is a cleaning material that provides a cleaning effect by utilizing the emulsification, dispersion, and solubilizing action of a surfactant. Examples of the surfactant type detergent include soap and shampoo. In soaps and shampoos, anionic surfactants and amphoteric surfactants are blended as cleaning components. In addition, it is known that additives such as a foaming agent, a conditioning component, and a moisturizing component can be blended with soap and shampoo. As the foam-increasing agent, fatty acid monoethanolamide, which is a nonionic surfactant, or the like is used. As the conditioning component, a cationic surfactant or a cationic polymer is used. As the moisturizing component, glycine betaine or the like is used.

  In recent years, for the purpose of enhancing the foaming effect and imparting a moist feeling, a method has been proposed in which an oily component such as a high-grade alcohol or a pasty oil is blended with soap or shampoo (Patent Documents 1 to 3). ). However, in the same way that soap and shampoo detergency declines due to sebum and oil stains, the detergency declines when an oil component is added. Moreover, since an oil-based component is a defoaming component, foaming power falls with an oil-based component. In addition, since emulsification occurs when the blending amount of the oil component exceeds the solubilization amount of the preparation, there arises a problem of loss of transparency and deterioration of stability. In particular, when the emulsion is liquid, it is difficult to ensure stability from its properties. From the above, the amount of the oil component added to the liquid surfactant type detergent is limited.

  Further, the improvement of the detergency can be easily improved by increasing the blending amount of the surfactant. However, when a large amount of surfactant is added, thickening and gelation occur, and the spreadability of the preparation, the compatibility between the preparation and skin and hair, and the compatibility between the preparation and dirt may be reduced during application. Are known. In addition, it is known that problems such as bad fingering during hair washing, crispness and stiffness after drying, and bad fingering occur, resulting in an unfavorable finish as a cleaning material.

  For this reason, attempts have been made to improve detergency while suppressing a decrease in feeling of use by various methods rather than simply increasing the amount of surfactant.

  One is a method in which a surfactant is increased to improve the detergency, and at the same time, a component that improves the feeling of use is used. For example, a method of blending a cationic polymer or a highly polymerized silicone as a conditioning agent has been proposed. However, although these methods can maintain an excellent feeling of use to some extent, there arises a new problem that cationic polymers and highly polymerized silicone accumulate on the hair due to continuous use.

  As another method, there has been proposed a method of trying to improve the detergency by a method other than increasing the amount of the surfactant. For example, a method of blending a silicone surfactant (Patent Document 4), a method of blending a water-soluble oil such as succinic acid diester (Patent Document 5), and a surfactant phase generated by blending the surfactant are used. A method (Patent Document 6) has been proposed. However, when these methods are used, an excellent feeling of use can be maintained to some extent, but, for example, cleaning properties against oil stains that are difficult to remove, such as mascara and hair wax, are not sufficient. Therefore, when the above method is adopted, it is difficult to sufficiently wash away mascara and the like with the skin cleansing agent, and it is difficult to sufficiently wash away hair wax and the like with the hair cleansing agent.

  On the other hand, the solvent-type cleaning material is a cleaning material that contains an oily component as a solvent, and that has a cleaning effect by dissolving oil stains in the oily component. As an example of the solvent-type cleaning agent, a cleansing agent that is a cleaning agent for skin can be mentioned. Examples of cleansing agents include clear liquid cleansing oil that is one phase of oil (which may solubilize a very small amount of water), cleansing cream (milk) that is an emulsified type of W / O or O / W, Cleansing gels (gels) and cleansing liquids based on special transparent one-phase structures (phases) comprising nonionic surfactants, polyols, water, and oily components are known. Since these solvent-type detergents contain a large amount of oily components, they exhibit high detergency against oil stains that are difficult to remove, such as the aforementioned mascara and hair wax.

  These four types of cleansing agents have greatly different effects due to differences in the cleaning mechanism (structure). Specifically, cleansing creams that are emulsified type have excellent washability but have the lowest detergency. In addition, when the cleansing cream is liquid, it is difficult to ensure stability from its properties. Cleansing oil, which is a single phase of oil, has the best cleaning power, but it does not have excellent washability. Cleansing gels and cleansing liquids have a higher detergency than emulsifying cleansing creams because they are based on special structures. Furthermore, cleansing gels and cleansing liquids provide functionality and usability that are far superior to cleansing oils because, for example, multiple face washings are not required in the scene of washing. Liquid cleansing liquids exhibit properties that are superior in usability, such as the spreadability of the formulation and make-up familiarity, than solid cleansing gels with different structures. In addition, cleansing liquid is based on a special one-phase liquid structure, and therefore exhibits excellent stability even when it is liquid.

  However, cleansing liquids that are said to be most excellent in the feeling of use also have a viscosity unique to the preparation and an excellent detergency, but the feeling of use is not fully satisfactory.

  Since cleansing liquid is based on a special structure, stability, functionality, and feeling of use are limited and determined by the type and amount of components. For example, when a special structure breaks down, transparency is deteriorated and stability is deteriorated, and two-phase separation occurs. For this reason, it is difficult to change the blending, configuration and blending amount of optional components for the purpose of improving functionality and usability. Liquid cleansing liquids are more susceptible to stability due to structure formation than solid cleansing gels, and it is difficult to adjust functionality and feel. For example, when the amount of the surfactant is increased in order to improve stability and detergency, the preparation is thickened and the feeling of use is lowered. If the amount of water is increased to improve the feeling of use or reduce the viscosity of the preparation, stability is lost. In addition, when an anionic surfactant or an amphoteric surfactant is used to impart cleaning properties with components other than the oily component, transparency is lost, stability is deteriorated, and a feeling of use is reduced due to thickening of the preparation. In addition, when a cationic surfactant is used for the purpose of improving the finish in use on hair, transparency is lost, stability is deteriorated, and a feeling of use is reduced due to thickening of the preparation.

  From the above, in detergents, detergents such as soap and shampoo are excellent in usability, but they are sufficiently satisfactory in cleaning performance against oil stains represented by mascara and hair wax. It's not going. Solvent-type detergents are cleansing liquids that exhibit excellent cleaning properties against oil stains, such as mascara and hair wax, but are relatively excellent in use feeling among solvent-type detergents. However, the feeling of use is not fully satisfactory. In addition, it is difficult for the cleansing liquid to change the composition, composition and amount of optional components for the purpose of improving functionality and usability.

  The nonionic surfactant preferably contains a fatty acid type nonionic surfactant from the viewpoint of obtaining a liquid cleaning material that is more excellent in stability. In addition, the nonionic surfactant may contain at least one selected from the group consisting of alkyl glyceryl ether, glycol fatty acid ester, glycerin fatty acid ester, polyoxyalkylene glyceryl ether fatty acid ester and fatty acid amide. More preferably, it contains at least one selected from the group consisting of glycol fatty acid esters, polyoxyalkylene glyceryl ether fatty acid esters and fatty acid amides.

  Content of the said nonionic surfactant is 8-45 mass% in 100 mass% of liquid cleaning materials, Preferably it is 10-40 mass%. The reason is that when the content of the nonionic surfactant is less than 8% by mass, a liquid detergent having excellent stability cannot be obtained. In addition, when the content of the nonionic surfactant exceeds 45% by mass, the exacerbation of the spreadability of the preparation caused by the increase in viscosity caused by the blending of the nonionic surfactant and the deterioration of the compatibility between the preparation and the skin and hair are remarkable. This is because a squeaky feeling at the time of application, a feeling of stickiness / stiffness after drying, and a feeling of crispness become conspicuous, and a liquid detergent excellent in feeling of use cannot be obtained.

(Oil component that is liquid at 25 ° C)
The oily component that is liquid at 25 ° C. is not particularly limited, and examples thereof include oils and fats, hydrocarbon oils, higher alcohols, fatty acid ester oils, and silicone oils.

  Examples of the fats and oils include sunflower oil, cottonseed oil, soybean oil, olive oil, coconut oil, castor oil, rapeseed oil, and cocoon oil.

The oily component that is liquid at 25 ° C. is selected from branched hydrocarbon oils, branched fatty acid ester oils, phenyl-modified silicones, and cyclic silicones from the viewpoint of obtaining a liquid detergent having excellent usability and higher detergency. It is preferable to contain at least one kind.

  Preferable examples of the branched hydrocarbon oil include liquid isoparaffin and light isoparaffin. Preferable examples of the branched fatty acid ester oil include isopropyl myristate, isopropyl palmitate, cetyl 2-ethylhexanoate, 2-ethylhexyl palmitate, isononyl isononanoate and the like. Preferable examples of the phenyl-modified silicone include methylphenyl polysiloxane. Preferred examples of the cyclic silicone include octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, dodecamethylcyclohexasiloxane, methylcyclopolysiloxane, and the like.

  The content of the oily component that is liquid at 25 ° C. is not particularly limited, and can be appropriately changed according to the blending amount of other components. The content of the oily component that is liquid at 25 ° C. is preferably 5 to 40% by mass, more preferably 5 to 35% by mass, in 100% by mass of the liquid cleaning material. The reason for this is that when the content of the oily component that is liquid at 25 ° C. is 5% by mass or more, a liquid cleaning material that is more excellent in detergency can be obtained. Moreover, it is because the liquid cleaning material which is more excellent by stability can be obtained as content of the oil-based component which is liquid at 25 degreeC is 40 mass% or less.

(At least one of polyol and ethanol)
Although at least one of the polyol and ethanol is not particularly limited, for example, ethylene glycol, diethylene glycol, triethylene glycol, polyethylene glycol, propylene glycol, dipropylene glycol -L, isoprene glycol, 1,3-butylene glycol, 1,2-butanediol, 1,2-pentanediol, 1,2-hexanediol, 1,2-octanediol, , 2-decandiol, glycerin, concentrated glycerin, diglycerin, polyglycerin and the like. Only one kind of the polyol and ethanol may be used, or two or more kinds may be used in combination.

  The content of at least one of the polyol and ethanol is not particularly limited, and can be appropriately changed according to the blending amount of other components. The content of at least one of the above-mentioned polyol and ethanol is preferably 5 to 40% by mass, more preferably 5 to 35% by mass, in 100% by mass of the liquid detergent. The reason is that the effect of the present invention can be more effectively obtained when the content of at least one of the polyol and ethanol is 5% by mass or more. Further, when the content of at least one of the above-mentioned polyols and ethanol is 40% by mass or less, a liquid cleaning material that is more excellent in stability can be obtained.

(Betaine compound)
The betaine compound has a betaine structure, has a molecular weight of 300 or less, and does not have a hydrophobic group portion having 10 or more carbon atoms in addition to the betaine structure which is a hydrophilic group portion.

Examples of the betaine compound not included in the betaine compound include amphoteric surfactants such as amidopropyl betaine laurate and amphoteric polymers such as methacryloylethyldimethylammonium / methylcarboxybetaine / butyl methacrylate copolymer.

  Examples of the betaine compound include glycine betaine, alanine betaine, valine betaine, lysine betaine, glutamic acid betaine, trigonelline, and carnitine. The betaine compound may be used alone or in combination of two or more. The betaine compound is more preferably glycine betaine.

  A commercial item may be used for the betaine compound. Examples of commercially available products of glycine betaine include amino coat (trade name, manufactured by Asahi Kasei Chemicals Corporation). Moreover, as a commercial item of the mixed raw material containing glycine betaine, PRODUU 400 (trade name, manufactured by Ajinomoto Co., Inc.) can be exemplified.

  Content of the said betaine compound is 0.5-40 mass% in 100 mass% of liquid cleaning materials, Preferably it is 0.5-35 mass%, More preferably, it is 0.5-30 mass%. . The reason for this is that when the content of the betaine compound is less than 0.5% by mass, the increase in viscosity caused by the incorporation of the nonionic surfactant causes deterioration of the spreadability of the preparation and the deterioration of the compatibility between the preparation and the stain. This is because it cannot be effectively suppressed, and a liquid cleaning material with excellent usability cannot be obtained. Moreover, it is because the liquid detergent which is excellent in stability cannot be obtained when the content of the betaine compound exceeds 40% by mass.

(Other details of liquid cleaning materials)
In the liquid cleaning material of the present invention, the special structure is preferably a transparent one-phase structure. In this case, the transparency of the preparation can be used as a measure of the formation of the structure and the determination of stability. For example, an opaque liquid cleaning material does not form a special structure and is an emulsified type, and exhibits a lower detergency than the case where a structure is formed. If the liquid cleaning material is opaque, it can be easily determined that the liquid cleaning material is not excellent in stability.

  The term “transparent” in the present invention means that when a liquid cleaning material is placed in an annular transparent glass container having a diameter of 5 cm, the background behind the glass container can be visually observed through the glass container. “Transparent” includes translucent. The liquid cleaning material of the present invention may be slightly cloudy. The term “liquid” in the present invention indicates that the liquid is liquid at 25 ° C., and that the liquid cleaning material has fluidity at 25 ° C.

  The liquid cleaning material of the present invention can be produced by various methods. By mixing and stirring the constituent components of the present invention in an arbitrary order, the cleaning material of the present invention can be easily obtained. For example, a nonionic surfactant, an oily component that is liquid at 25 ° C., and at least one of polyol and ethanol are mixed and stirred to obtain a transparent liquid. Next, after adding purified water to the obtained transparent liquid composition and mixing and stirring, the betaine compound can be added and dissolved to obtain the liquid cleaning material of the present invention.
