Description

The present invention relates to a creamy cleaning composition which is excellent in usability, gives a high degree of satisfaction during washing, and has good stability over time.

As a cleaning composition typified by a face wash, a cream-like composition having fine bubbles, a comfortable feeling, and good washability is preferred to a liquid one, and is widely used.
Such a creamy cleaning composition generally has a lamella gel structure formed of a fatty acid and / or a fatty acid salt, a polyhydric alcohol, and water, and is stable over time with a polyhydric alcohol such as glycerin. It has good properties (Non-Patent Documents 1 and 2). Further, it has been reported that an appropriate viscosity can be imparted by blending ethanol instead of polyhydric alcohol (Patent Document 1).
In addition, a high amount of fatty acid is added to produce a creamy foam, and a high molecular compound (thickener) is added to slow down the discharge of water between the foam films to form an elastic foam. , Improving foam quality is also being considered. Further, it is known that a nonionic surfactant, an anionic surfactant, and an amphoteric surfactant are blended in order to ensure good foaming (Patent Document 2). In addition, polymer compounds, nonionic surfactants, anionic surfactants, and amphoteric surfactants are usually used in cleansing compositions for the purpose of imparting a moist feeling after washing and smoothness of the skin. It is an ingredient to be blended. As described above, various studies have been made in search of better usability and feel (Patent Documents 3 to 5).

In the cleaning composition, it is an important point in demand that both excellent foam quality gives a feeling of satisfaction and good foaming and rinsing make it highly usable.
However, when a thickener such as a polymer compound is blended to form an elastic foam, the water solubility becomes poor and it becomes difficult to foam. In order to eliminate this, if a surfactant other than the fatty acid such as a nonionic surfactant or an anionic surfactant is blended as in the conventional case, a slimy feeling occurs at the time of washing, which may not be preferable.
In view of such a situation, the present invention is a creamy cleaning composition which is highly usable in foaming and rinsing, provides a high degree of satisfaction during cleaning due to its excellent foam quality, and has good stability over time. The challenge is to provide.

As a result of diligent research, the present inventors have reduced the total content of predetermined polyhydric alcohols and ethanol to suppress the formation of a gel structure and improve water solubility, while adding a thickener. Then, by adjusting the neutralization rate of fatty acids, it was conceived to achieve a creamy preparation having excellent stability over time, and the present invention was completed.

That is, the present invention is as follows.
[1] It contains (a) a fatty acid and / or a fatty acid salt, and (b) a polymer compound of 1.5 to 3.0% by mass of the entire composition, which can impart viscosity even in the presence of a salt. c) A creamy cleaning composition in which the total content of polyhydric alcohol and ethanol having three or more hydroxyl groups in one molecule is 3.0% by mass or less of the entire composition.
[2] The cleaning composition according to [1], wherein the fatty acid has a neutralization rate of 70 to 95 mol%.
[3] The cleaning composition according to [1] or [2], which further contains (d) a cationized polymer containing dimethyldiallyl ammonium chloride in an amount of 0.01 to 1.0% by mass based on the total composition.
[4] The cleaning composition according to any one of [1] to [3], wherein the total content of (a) fatty acid and / or fatty acid salt is 20% by mass or more of the total composition.
[5] (b) The polymer compound that can impart viscosity even in the presence of a salt is selected from the group consisting of hydroxypropylmethyl cellulose, hydroxyethyl cellulose, and hydroxypropyl cellulose, according to any one of [1] to [4]. The cleaning composition described.

Since the cleaning composition of the present invention has good water solubility, it is easy to foam and has good washing off. Further, when the cleaning composition of the present invention is whipped, a good quality foam, that is, an elastic and creamy foam is obtained. Moreover, the cleaning composition of the present invention has good stability over time. Therefore, the present invention provides a creamy cleaning composition that is excellent in usability, provides a high degree of satisfaction during cleaning, and has good stability over time.

The present invention contains (a) a fatty acid and / or a fatty acid salt, and (b) a polymer compound of 1.5 to 3.0% by mass of the entire composition, which can impart viscosity even in the presence of the salt. (C) A creamy cleaning composition in which the total content of polyhydric alcohol and ethanol having three or more hydroxyl groups in one molecule is 3.0% by mass or less of the total composition.

In the present invention, (a) fatty acid and / or fatty acid salt is not particularly limited, but preferably contains one having 12 to 18 carbon atoms. It is not excluded that fatty acids or fatty acid salts other than those having 12 to 18 carbon atoms are also contained in the composition of the present invention. Further, the fatty acid and / or the fatty acid salt may be saturated or unsaturated, or have or do not have a branched chain.

The total content of (a) fatty acid and / or fatty acid salt in the composition of the present invention is preferably 20% by mass or more, more preferably 20 to 35% by mass, based on the whole composition. If it is less than 20% by mass, the foam quality may deteriorate. On the other hand, if it is larger than 35% by mass, the water solubility may be deteriorated.

In general, it is known that a fatty acid soap-based cleaning composition becomes liquid when the fatty acid neutralization rate is increased, and becomes creamy or paste-like when the fatty acid neutralization rate is decreased.
In the present invention, the neutralization rate of fatty acids is preferably 70 to 95 mol%, more preferably 75 to 90 mol%, in order to bring the composition into a stable cream state over time. If the neutralization rate of the fatty acid is larger than 95 mol%, the stability of the preparation over time may be deteriorated or the foam quality may be deteriorated. On the other hand, if the neutralization rate of fatty acid is less than 70 mol%, the stability of the preparation over time may deteriorate.

The fatty acid neutralizer is not particularly limited as long as it is usually used in a washing composition such as face wash, and for example, potassium hydroxide, sodium hydroxide, triethanolamine, L-arginine and the like are used. Can be done.

The composition of the present invention may also contain a surfactant other than the fatty acid as described later, but the proportion of the neutralized fatty acid in the total content of the surfactant is preferably 70% by mass or more. If such a ratio is less than 70% by mass, the foam quality may deteriorate.
Further, when the total content of the nonionic surfactant, the anionic surfactant, and the amphoteric surfactant is 20% by mass or less with respect to the total content of the surfactant, the feeling at the time of rinsing becomes dull. It is preferable because it does not stick and is clean.
In the composition of the present invention, the content of the surfactant is preferably 20 to 35% by mass with respect to the entire composition including (a) fatty acid and / or fatty acid salt.

In the present invention, (b) a polymer compound capable of imparting viscosity even in the presence of a salt acts as a so-called thickener, makes the composition creamy, and imparts stability over time to the composition. ..
Here, the "polymer compound that can impart viscosity even in the presence of salt" refers to a compound having so-called salt resistance. Usually, an arbitrary addition amount of the polymer compound can impart the same viscosity as that in the condition where no electrolyte is present even under the condition where an electrolyte such as sodium chloride is present in an amount of 0.1% by mass or more. Say.
The polymer compound is not particularly limited, but a cellulosic thickener is preferable, and hydroxypropylmethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, methyl cellulose, ethyl cellulose, hydroxypropyl methyl cellulose stearoxy ether and the like are preferable. Hydroxypropyl methylcellulose, hydroxyethyl cellulose, and hydroxypropyl cellulose are more preferred. The molecular weight and the degree of polymerization are not particularly limited as long as they are of a size normally used as a thickener.
Commercially available products can be obtained. For example, as hydroxypropylmethyl cellulose, Metrose 60SH4000 (manufactured by Shin-Etsu Chemical Co., Ltd.), Metrose 90SH4000 (manufactured by Shin-Etsu Chemical Co., Ltd.), Marporose 60MP4000 (Matsumoto Yushi Pharmaceutical Co., Ltd.) Made by the company).

The content of the polymer compound (b) that can impart viscosity even in the presence of a salt in the composition of the present invention is 1.5 to 3.0% by mass, preferably 2.0 to 2.% of the entire composition. It is 5% by mass. If it is larger than 3.0% by mass, the water solubility becomes poor, and foaming and rinsing may become unsatisfactory. On the other hand, if it is less than 1.5% by mass, the viscosity may not be sufficiently imparted and the cream may not be formed.

The composition of the present invention does not contain or contains a small amount of polyhydric alcohol and ethanol having three or more hydroxyl groups in one molecule, and specifically, the total content is 3.0% by mass of the entire composition. It is as follows.
Generally, in a fatty acid soap-based cleaning composition, the lamella gel structure is stabilized by containing a polyhydric alcohol having three or more hydroxyl groups in one molecule, but in the present invention, this is not contained or the amount is small. This suppresses the formation of the lamella gel structure and improves the water solubility. Further, in general, the composition can be imparted with viscosity by containing ethanol, but in the present invention, water solubility is improved by not containing this or by using a small amount.
Regarding the stability of the preparation over time, the neutralization rate of the above-mentioned fatty acids should be within a specific range, and (b)
It is secured by containing a predetermined amount of the polymer compound.
