Description

The present invention relates to a cleaning agent. More specifically, the present invention relates to a cleaning agent containing an anionic surfactant and a predetermined monoglycerin fatty acid ester in a predetermined mass ratio, having high stability even when a large amount of an oily raw material is blended, and having good foaming.

An oil-based cleaning agent may be added to an aqueous cleaning agent for the purpose of removing stains on the face, body, hair, etc., for the purpose of imparting a moist feeling after cleaning. For example, Patent Document 1 discloses an aqueous skin cleansing agent containing a total of 0.1 to 20% by weight of a hydrocarbon-based paste-like oil and a non-hydrocarbon-based paste-like oil. Further, Patent Document 2 discloses a detergent composition containing 10 to 50% by mass of an oily component, 20 to 50% by mass of a fatty acid alkanolamide, and an anionic surfactant.

However, when a large amount of oil-based raw material is added to the aqueous cleaning agent, there is a problem that stability is impaired and a problem that foaming is deteriorated. In this regard, although it has been confirmed that the aqueous skin cleansing agent described in Patent Document 1 has good foaming and is stable for 2 months in a cleansing agent containing 0.2 to 10% by weight of an oil agent. It is unclear whether good foaming and storage stability can be obtained for those containing more oil. Further, regarding the cleansing composition described in Patent Document 2, although it has been confirmed that the cleansing agent containing 15 or 20% by weight of the oily component was able to sufficiently cleanse and wash the face, foaming was also observed during storage. Stability has not been verified and is unknown. That is, even in view of these patent documents, a cleaning agent having high stability and good foaming is not yet sufficiently supplied even if a large amount of oil-based raw materials are blended. The present invention has been made to solve the above problems, and an object of the present invention is to provide a cleaning agent having high stability and good foaming even when a large amount of oil-based raw materials are blended.

It is a table which shows the composition of the cleaning agent, the height of foam at the time of foaming them, and the sensory evaluation result of foaming by hand.

Hereinafter, the present invention will be described in detail.

"Cleaning agent" means a product intended to remove stains. The aqueous cleaning agent refers to a cleaning agent containing water as a base, a dispersion medium or a solvent. Further, the "foaming cleaning agent" refers to a cleaning agent having the property of foaming by adding an appropriate amount of water and foaming to generate bubbles.

In the present invention, stability refers to the degree of state change when stored for a certain period of time. That is, "stability", "high stability", or "good stability" means that there is no or little state change after a certain period of time, or that the period until the state change occurs is long. To say. On the contrary, "instability", "low stability" or "poor stability" means that the state change is large such as separation of the liquid phase after a certain period of time, or until the state change occurs. It means that the storage period of is short. Stability can be evaluated, for example, by placing the cleaning agent in a closed container, storing it at a relatively high temperature of about 40 ° C. for a certain period of time, and then visually observing the state.

In the present invention, "foaming" refers to the way foaming or the state of foaming when the cleaning agent is foamed, and can be used synonymously with "foaming force". That is, "good foaming" means that the foaming is fast when the cleaning agent is foamed, the amount of foam generated is large, and the like. On the contrary, "poor foaming" means that the foaming is slow when the cleaning agent is foamed, the amount of foam generated is small, and the like.

The bubbling can be evaluated by, for example, the following methods (1) to (4). In the examples described later, the height of the generated bubbles is measured and evaluated by the method according to the following (3). Alternatively, for convenience, the cleaning agent may be picked up and foamed by hand, and the speed of foaming, the amount of foam, the quality of foam, and the like may be sensory-evaluated visually and tactilely.
(1) Drop method (Loss-Miles method): The test solution is dropped from a constant height to the bottom at a constant speed in a vertically erected glass tube, and the height of bubbles generated at that time is measured. In addition, the height 5 minutes after the end of the fall is measured to evaluate the sustainability of the foam.
(2) Shaking method: Shake the closed container containing the test solution up and down, and measure the volume of bubbles generated.
(3) Stirring method: A mixer device containing a test solution is rotated at a constant speed, and the volume of bubbles generated is measured.
(4) Air supply method: Air is sent at a constant flow rate from a tube attached to the test solution, and the volume of bubbles is measured.

Since the cleaning agent according to the present invention can contain a large amount of oil-based raw materials, it can give a moist feeling to the skin after use. Therefore, the cleaning agent according to the present invention can be, for example, a cleaning agent used for the skin such as makeup remover (cleansing), washing pigment, body soap, and whole body shampoo.

Since the cleaning agent according to the present invention can contain a large amount of oil-based raw materials, it is possible to give the hair a moist feeling, a cohesive feeling, and good finger passage after use. Therefore, the cleaning agent according to the present invention can be, for example, a cleaning agent used for hair such as hair shampoo.

The "oil-based raw material" refers to a substance having the property of being soluble in oil and insoluble in water.

Oily raw materials used in cosmetics are generally classified into fats and oils, higher fatty acids, waxes, hydrocarbons, esters, higher alcohols, silicone oils, etc. based on their chemical structures, and any of these is used. be able to. Further, any oil-based raw material in a liquid state, a solid state, or a semi-solid state (paste form, etc.) at room temperature can be used.

For example, examples of the oil and fat include horse oil, palm oil, shea butter, shea butter oil, rice germ oil, olive oil, camellia oil, grape seed oil, macadamia nut oil, sunflower oil, apricot oil, triethylhexanoin and the like. Examples of higher fatty acids include palm oil fatty acids, behenic acid, lauric acid, myristic acid, palmitic acid, stearic acid, isostearic acid and the like, and examples of waxes include jojoba seed oil, carnauba wax and candelilla wax. Mitsurou, lanolin, etc. can be exemplified, and examples of the hydrocarbon include olefinic hydrocarbons such as hydrogenated polyisobutene, isododecane, and tetradecene, mineral oil (liquid paraffin), paraffin, vaseline, selecin, microcrystallin wax, squalane, and the like. Examples of the esters include cetyl palmitate, ethylhexyl palmitate, isopropyl myristate, 2-octyldodecyl myristate, cetyl 2-ethylhexanoate, diisostearyl malate and the like. Examples of the higher alcohol include cetyl alcohol, stearyl alcohol, isostearyl alcohol, 2-octyldodecanol and the like, and examples of the silicone oil include straight silicone oil such as dimethicone, amino-modified silicone oil such as amodimethicone, and stearyl. Examples thereof include alkyl-modified silicone oils such as dimethicone, polyether-modified silicone oils such as PEG-12 dimethicone, phenyl-modified silicones such as methylphenylpolysiloxane, and cyclic polysiloxanes such as cyclopentasiloxane.

One type of oil-based raw material may be blended alone in the cleaning agent, or two or more kinds may be blended in combination. The blending amount of the oily component can be appropriately set according to the intended use of the cleaning agent, the place of application, the desired feeling of use, etc., but from the viewpoint of stability, assuming that the entire cleaning agent is 100, it is 0% by mass or more.

Glyceryl acid, glyceryl isostearate, glyceryl oleate and glyceryl behenate were used. For Samples 1 to 4, the height of the foam and the foaming by hand were evaluated by the same method as in Example 10. The composition of sample numbers 1 to 4, the height of the foam, and the sensory evaluation result of the foaming by hand are shown in FIG.

As shown in FIG. 11, No. 1 and No. The height of the bubble of No. 4 is 0 cm, and No. The height of the bubble of No. 2 is 5.3 cm, and No. The height of the bubble of 3 was 3.8 cm. On the other hand, No. None of 1 to 4 foamed by hand. That is, the cleaning agent containing glyceryl stearate and glyceryl behenate did not foam at all. In addition, the cleaning agent containing glyceryl isostearate and glyceryl oleate foamed in the homomixer, but did not foam by hand. Further, the cleaning agent containing glyceryl isostearate and glyceryl oleate was sticky and uncomfortable to use because a large amount of oily components adhered to the beaker wall surface and hands after rinsing with water after foaming evaluation. From this, it became clear that all of them lacked practicality as cleaning agents that can be used on a daily basis.

From this result, in order to obtain a cleaning agent with good foaming even when a large amount of oily raw material is blended in combination with an anionic surfactant in a predetermined mass ratio, the monoglycerin fatty acid ester is glyceryl caprylate or capric acid. Glyceryl, glyceryl undecylene, glyceryl laurate and / or glyceryl myristate were found to be preferred.
