JP6900496B2 - Semi-solid cleaning agent - Google Patents

Description

The present invention relates to a semi-solid detergent. More specifically, the present invention relates to a semi-solid cleanser useful for facial cleansers, body soaps, hand soaps and the like.

Detergents using fatty acid salts (soap) are widely used because they have excellent detergency for sebum stains and a refreshing feeling after washing. Further, from the viewpoint of usability and good foaming, semi-solid detergents such as gel-like detergents, cream-like detergents and paste-like detergents are preferred.

Conventionally, a creamy detergent in which higher fatty acids are gelled with a polyhydric alcohol and a nonionic surfactant is generally used, but such a creamy detergent is higher in order to make it semi-solid. It is necessary to add an excess amount (for example, 30% by mass or more) of fatty acid (see Patent Document 1).

JP-A-2002-167325

In recent years, it is said that some of higher fatty acids and salts thereof (sometimes referred to as "higher fatty acids (salts)") cause rough skin, and it is required to reduce the amount of fatty acids blended. However, if the amount of fatty acid blended in the cream-like detergent is reduced, the viscosity at room temperature decreases, making it difficult to form a semi-solid shape, and the change in viscosity at high temperature increases, resulting in a decrease in storage stability. There was a problem of doing.

Therefore, an object of the present invention is to provide a semi-solid detergent having excellent storage stability despite a small amount of the higher fatty acid and a salt thereof.

As a result of diligent studies to achieve the above object, the present inventor has found that component (A): higher fatty acid and / or salt thereof, and component (B): solid at 20 ° C. and 16 to 20 carbon atoms. According to the semi-solid detergent containing alcohol and the component (C): carboxyvinyl polymer and the content ratio of the component (A) is within a specific range, the amount of the higher fatty acid and its salt is small. Nevertheless, it has been found that a semi-solid detergent having excellent storage stability can be obtained. The present invention has been completed based on these findings.

That is, the present invention contains the following component (A), the following component (B), and the following component (C), and the content ratio of the above component (A) is 5.0 to 25.0% by mass. A solid cleaning agent is provided.

The component (C) is preferably a (Acrylate / alkyl acrylate (C10-30)) crosspolymer.

The semi-solid detergent of the present invention is excellent in storage stability even though the amount of the higher fatty acid and its salt is small. Further, according to the semi-solid detergent of the present invention, despite the small amount of the higher fatty acid and its salt, the detergent foams, stretches during application, and foams while maintaining the conventional detergency. It is possible to make the quality excellent.

The semi-solid detergent of the present invention contains at least a higher fatty acid and / or a salt thereof; a higher alcohol which is solid at 20 ° C. and has 16 to 20 carbon atoms; and a carboxyvinyl polymer.

It can be appropriately selected from the range described so that the total content ratio in the semi-solid detergent is 100% by mass or less.

Further, in the present specification, the “semi-solid state” refers to properties such as gel, cream, and paste having low fluidity. For example, "semi-solid" means that a polypropylene tube container (100 mL capacity, inner diameter of the discharge port is 5 mm) is filled with 50 g of a cleaning agent up to the discharge port, and the discharge port of this tube container is directed downward at 20 ° C. It refers to a state in which it does not easily drip when held for 10 seconds in the atmosphere of.

Examples of the salt in the higher fatty acid salt include alkali metal salts such as sodium salt and potassium salt; alkanolamine salts such as monoethanolamine salt, diethanolamine salt and triethanolamine salt. The higher fatty acid salt in the semi-solid detergent of the present invention may be a salt containing a higher fatty acid salt prepared in advance, or may be blended as a higher fatty acid and a base, respectively, to form a semi-solid detergent. It may be formed from higher fatty acids and bases in the process of producing.

The component (A) is preferably a higher fatty acid (salt) having 10 to 20 carbon atoms. When the higher fatty acid (salt) has 10 or more carbon atoms, the semi-solid detergent has an appropriate viscosity and is more excellent in detergency. When the higher fatty acid (salt) has 20 or less carbon atoms, it has excellent water compatibility, so that foaming is more excellent, and storage stability is more excellent. The carbon number of the higher fatty acid (salt) is more preferably 12 to 18, still more preferably 12 to 14 (particularly lauric acid and myristic acid) from the viewpoint of being superior in foaming and foam quality.

The component (A) preferably contains myristic acid from the viewpoint of maintaining a semi-solid state and being more excellent in storage stability, as well as being more excellent in foaming and foam quality. In addition, it is preferable to contain lauric acid from the viewpoint of better compatibility with water and particularly excellent initial foaming.

When the content ratio is 5.0% by mass or more, it exhibits detergency and functions as a cleaning agent, has excellent foaming and foam quality, has an appropriate viscosity, and has excellent storage stability. When the content ratio is 25.0% by mass or less, rough skin is less likely to occur, and the spreadability at the time of application is excellent. The content ratio of the component (A) is the total of the content ratios of all the components (A) in the semi-solid detergent of the present invention.

When the component (A) contains myristic acid, the content ratio of myristic acid in the semi-solid detergent of the present invention is 10.0% by mass or more with respect to 100% by mass of the total amount of the component (A).

[Component (B): Higher alcohol which is solid at 20 ° C. and has 16 to 20 carbon atoms]
The higher alcohol, which is the component (B) and is solid at 20 ° C. and has 16 to 20 carbon atoms, forms a semi-solid state when the amount of the component (A) is small when used in combination with the component (C). It also has the effect of improving storage stability. Specifically, the cleaning agent can be made into a semi-solid state by using a higher alcohol that is solid at 20 ° C. Further, among higher alcohols that are solid at 20 ° C., those having 16 or more carbon atoms have an appropriate viscosity to prevent the detergent from dripping, and those having 20 or less carbon atoms have high lipophilicity. It is presumed that it is not too much and it is appropriate, and since the detergent has a gel structure, it is excellent in storage stability in a semi-solid state. As the component (B), only one kind may be used, or two or more kinds may be used.

Examples of the component (B) include cetanol (cetyl alcohol), stearyl alcohol, arachidyl alcohol, and cetostearyl alcohol.

Also, the storage stability is better. When the content ratio is 10.0% by mass or less, the semi-solid detergent is suppressed from being hardened, and the semi-solid detergent is more excellent in spreading and adapting. The content ratio of the above component (B) is the total content ratio of all the components (B) in the semi-solid detergent of the present invention.

Above all, the semi-solid detergent of the present invention is preferably filled in a tube container because of its excellent discharge property.

When the blending amount of the fatty acid (salt) is reduced in the conventional semi-solid detergent containing the fatty acid (salt), the viscosity is lowered and the detergent becomes liquid instead of semi-solid. To solve this problem, it is conceivable to increase the viscosity by blending a carboxyvinyl polymer as a thickener. However, in this case, there are problems that the storage stability is lowered, the elasticity of the cleaning agent is increased, the elongation is poor, the dough is easily cut, and the water compatibility when whipping on the palm is poor and the foaming is poor. there were. On the other hand, in the semi-solid detergent of the present invention, even if the amount of the higher fatty acid (salt) [component (A)] is relatively small, the specific higher alcohol [component (B)] and carboxyvinyl are contained. By using the polymer [component (C)] in combination, the fatty acid (salt) is mixed in a small amount, but the mixture becomes semi-solid and has excellent storage stability. This is because the component (B) having a strong lipophilicity and the component (C) having hydrophilicity improve the affinity between the component (A) and water, and the components (A) to (C) and water are conventionally used. It is presumed that this is due to the formation of a highly stable gel that is different from the gel formed by the fatty acid (salt), nonionic surfactant and polyhydric alcohol. The semi-solid detergent of the present invention is also excellent in detergency, elongation, foaming, and foam quality.

Hereinafter, the present invention will be described in more detail based on Examples, but the present invention is not limited to these Examples.

The semi-solid detergent (Example) of the present invention was evaluated to be excellent in storage stability even though the blending amount of the higher fatty acid (salt) was 20% by mass or less, which was smaller than the conventional one. It was also evaluated to be excellent in elongation and foam quality. On the other hand, when the blending amount of the component (A) was small (Comparative Example 1), it was evaluated that the foam quality and storage stability were inferior. When the component (B) was not contained (Comparative Example 2), it was evaluated to be inferior in storage stability. When the component (C) was not contained (Comparative Example 3), it was judged that the solid state was not obtained and the storage stability was inferior. When behenyl alcohol was used without using component (B) (Comparative Example 4), it was evaluated to be inferior in storage stability.
