Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a transparent gel detergent composition comprising a fatty acid salt and a specific fatty acid alkanolamide type surfactant as main components.

[0002]

2. Description of the Related Art Skin cleansing compositions are classified into solid, liquid, and paste-like (gel-like) in terms of appearance. Among them, transparent gel-like cleansing compositions have a unique high-grade appearance. It is considered that the commercial value and marketability are high.

JP-A-59-232193, JP-A-59-232193
JP-A-232194 and JP-A-59-232195 disclose transparent gel detergent compositions containing an amino acid-based surfactant as a main component. However, it is disadvantageous in terms of cost due to the formation of smelt, and has a drawback that a slimy feeling is felt during washing and cedar.

Many transparent gel detergents using fatty acid salts, which are cheap and safe raw materials, have been proposed. Transparent gel compositions using fatty acid salts often have poor low-temperature stability due to the high crafting point of the fatty acid salts, and are often devised with counter ions or polyhydric alcohols or the like in the external phase to increase the solubility of the fatty acid salts. Proposals have been made to use it.

For example, JP-A-63-57699 discloses a gel which maintains transparency even at a low temperature by selecting a substance having a low Kraft point among soaps and adding a polyhydric alcohol in a high proportion of 10 to 40%. Detergent cleaning compositions have been proposed.

Further, in Japanese Patent Application Laid-Open No. 9-2221698,
The type of polyhydric alcohol is examined and the weight ratio of polyhydric alcohol having three or more hydroxyl groups in the molecule to water is 3: 5 to 5:
A technique of blending at a ratio of 5: 5 is disclosed. According to this disclosed technology, the fatty acid arginine salt forming the gel structure is specified at the same time as 20 to 40%, so that the total amount of polyhydric alcohol used in the formulation is as high as at least about 20%.

[0007] Although these techniques improve the low-temperature stability of the gel composition, they have a drawback that the foaming property and foam quality of the detergent composition are deteriorated because a large amount of polyhydric alcohol is blended. .

[0008]

An object of the present invention is to provide a transparent gel detergent which is stable even when stored at a low temperature or a high temperature and has a hardness which is easy to use. Another object of the present invention is to provide a transparent gel detergent composition having excellent irritation and low irritation.

[0009]

Means for Solving the Problems The present inventor added various additives to a blend system of a transparent gel composition comprising a fatty acid salt and water, and conducted studies on the stability and feeling of use of the transparent gel composition. As a result, by adding a specific fatty acid alkanolamide type surfactant, the low-temperature stability of the fatty acid salts is improved, the foaming of the fatty acid salt is enhanced, and the foam quality is creamy. The inventors have found that the present invention has been completed.

That is, the present invention relates to (Component A) a compound represented by the general formula (1):

[0011]

[0012] [wherein R ¹ is substituted by unsubstituted, or at least one hydroxyl group containing 6 to 22 carbon atoms, a straight-chain or branched alkyl or alkenyl group, R ² Is a hydrogen atom or 1 to 5 carbon atoms
M and n each independently represent an integer of 1 to 5, and m ≠ n when R ² is a hydrogen atom. The fatty acid alkanolamide type surfactant represented by the formula
The present invention relates to a transparent gel detergent composition comprising 1 to 20% by weight, (Component B) 25 to 70% by weight of a fatty acid salt, and (Component C) 30 to 75% by weight of water.

[0013]

BEST MODE FOR CARRYING OUT THE INVENTION Component B used in the present invention
Is a salt of a linear or branched saturated or unsaturated fatty acid having 8 to 22 carbon atoms which may contain a hydroxyl group. Such fatty acids include, for example, beef tallow, animal fats such as sheep oil, palm oil, palm kernel oil, olive oil, vegetable oils such as cottonseed oil, etc. One or two of fatty acids and fatty acid mixtures such as lauric acid, myristic acid, palmitic acid, stearic acid, oleic acid, 12-hydroxystearic acid or isostearic acid obtained by separation and purification.
A mixture of two or more species can be given.

The salt of the fatty acid salt of the component B used in the present invention includes alkali metal salts such as sodium and potassium of fatty acids, alkanolamine salts such as ammonium salt and triethanolamine salt, and basic salts such as arginine and lysine. At least one selected from amino acid salts can be mentioned. These fatty acid salts may be a single salt or a mixture of a plurality of salts.

In order to prepare these fatty acid salts, the fatty acid is previously converted to an alkali metal such as sodium or potassium,
Ammonium, alkanolamines such as triethanolamine and arginine, those neutralized by at least one or more selected from basic amino acids such as lysine may be used, and at the time of blending fatty acid and sodium hydroxide,
Alkali metal hydroxides such as potassium hydroxide, ammonia, alkanolamines such as triethanolamine and arginine, at least one or more selected from basic amino acids such as lysine are added separately from the fatty acids, in the compounding system Neutralization may be performed.

The cationic substance for neutralizing fatty acids will be described in more detail. When a basic alkali metal salt such as sodium or potassium is neutralized by itself or when an alkali metal soap is added, Since the gelation partially progresses during the production of the gel composition and the whole may not be homogenized, the neutralization of the fatty acid used alone with a strong basic substance is not preferable.

The use of a weakly basic alkanolamine or basic amino acid is more preferable because there is no problem such as partial gelation during the production of a gel detergent.

The fatty acid constituting the fatty acid salt of the component B of the present invention is, as described above, a saturated or unsaturated fatty acid salt (component B) having a straight or branched chain having 8 to 22 carbon atoms which may contain a hydroxyl group. Although it is a saturated fatty acid salt, if a large amount of fatty acid such as stearic acid, which raises the craft point of the salt, is blended in a large amount, inconvenience such as inability to maintain transparency or poor low-temperature stability may occur. It is more preferable that the fatty acid constituting the salt (component B) has at most 12% of the fatty acids having 12 or less carbon atoms in the fatty acid.

The neutralization equivalent to 1 mole of the fatty acid is 0.9 to
1.5 molar neutralization is desirable. More preferably, 1.0 to
When the neutralization equivalent is less than 0.9, the gel composition is not obtained. When the neutralization is more than 1.5, the gel form cannot be kept transparent. .

The compounding amount of the fatty acid salt in the transparent gel detergent of the present invention is 25% by weight to 70% by weight, more preferably 30% by weight to 45% by weight. When the amount of the fatty acid salt is less than 25% by weight, a gel form cannot be obtained. When the amount of the fatty acid salt exceeds 70% by weight, transparency cannot be ensured such as partial crystallization, which is not preferable.

The transparent gel detergent composition of the present invention is represented by the following general formula (1):

[0022]

These functions as an improvement in the feeling of use of the transparent gel detergent composition, a stabilizing agent, and a foaming modifier, and when incorporated into the transparent gel composition, they are within the scope of the present invention. It does not degrade the transparency and the stability of the mold.

As the fatty acid alkanolamide of the component A, when R ² is hydrogen in the formula (1), the low-temperature stability is deteriorated when m = n, which is not preferable. When R ² is an alkyl group having 1 to 5 carbon atoms, m and n
Each of them can independently have a structure of 1 to 5. Preferably m, n
More preferably, each is independently an integer of 1 to 3, and m + n is smaller than 5. When it is impossible to obtain a transparent gel composition when m and n alone or both exceed 5,
Alternatively, the composition becomes inferior in low-temperature stability, which is not preferable.

When R ² is an alkyl group having more than 5 carbon atoms, the foaming of the gel composition tends to decrease, which is not preferable.

The fatty acid alkanolamide of Component A is more preferably a fatty acid alkanolamide wherein R ² is a methyl group or an ethyl group and m = n = 1. More preferably, R ² is an ethyl group, and a fatty acid alkanolamide represented by m = n = 1 has a large improvement in moist feeling.

The compounding amount of the component A to the transparent gel detergent composition is preferably 0.01 to 10% by weight, more preferably 2 to 7% by weight. If the fatty acid alkanolamide of the component A is added in an amount exceeding 10% by weight, the transparency of the transparent gel detergent composition itself cannot be maintained. Problems such as poor low-temperature stability may occur, which is not preferable. Further, if the fatty acid alkanolamide of the component A is less than 0.01% by weight, the moist feeling and the foam quality are not improved, which is not preferable.

According to the composition shown in the following table, a sample of the transparent gel detergent was prepared. Thereafter, various samples were tested according to the following items. The evaluation test was omitted for samples that did not form a gel immediately after production. First, evaluation items will be described.

The components were blended according to the values in the gelation state table, heated to 80 ° C., and after confirming that the whole had become uniform, the mixture was cooled at 30 ° C. The state at the end of cooling was confirmed and evaluated according to the following evaluation criteria. ◎ Transparent gel state, hardness enough to allow finger to enter without resistance ○ Transparent gel state. Slightly hardened or high in fluidity × Cannot maintain transparent gel state. Flow or crystal precipitation

Low Temperature Stability Test The manufactured sample was packed in a poster color bottle, sealed, and allowed to stand in a -5 ° C. thermostat. After 7 days, the gel was visually observed and evaluated according to the following criteria. . ◎ No change from immediately after production ○ Slightly cloudy △ Cloudy, but returns to a transparent state when returned to room temperature × Cloudy or crystallizes and does not change state when returned to room temperature

Usability test (foaming, foam quality, comprehensive evaluation) For each gel detergent, 10 panelists conduct a hand-washing use test, and foaming (bubble volume) and foam quality (foam shape) during use , Foamy creaminess), and sensory test of overall feeling of use (comprehensive evaluation including the feeling of tightness after hand washing). The evaluation was performed as a five-point relative evaluation using Comparative Example 1 in Table 1 as a standard of three points, and the average score of the evaluation results was calculated. When the calculated average value was 4.5 or more, it was very good (（). The case of 0.5 to 3.5 was evaluated as good (○), the case of 3.5 to 3.0 was evaluated as normal (△), and the case of 3.0 or less was evaluated as poor (×).

[0056]

[Table 1]

As shown in Table 1, the transparent gel to which the fatty acid alkanolamide of Production Example 1 was added was superior to the transparent gel made of only the fatty acid salt, even though the concentration of the fatty acid salt was lowered. It has a feeling of use. The stability at low temperatures is also improved. If the fatty acid alkanolamide of Production Example 1 is added in an amount exceeding 15% by weight, the foam quality can be improved, but the foam volume decreases and at the same time the low temperature stability is improved. It turned out to be worse.

[0058]

[Table 2]

From Table 2 above, at 40% by weight of the fatty acid salt,
Although the gel form cannot be obtained, the gel form can be maintained by adding the alkanolamide of Production Example 1 at the same solid content concentration. The alkanolamide of Production Example 1 acts in the direction of enhancing the fatty acid salt gel, and at the same time has the effect of improving the usability.

[0060]

[Table 3]

Table 3 shows the results obtained by fixing the amount of the alkanolamide of Production Example 1 and changing the fatty acid salt content. Fatty acid salts could be stably blended from 37% by weight to 65% by weight. However, when the fatty acid salt content exceeded 50% by weight, the gel tended to harden, and the overall feeling of use in the hand washing test was that of a gel detergent. When trying to crush with the palm of the hand, a phenomenon that escapes in the direction in which the force was applied and is difficult to crush (referred to as “escape”) began to appear. Further, it was confirmed that when the fatty acid salt was added in an amount exceeding 65% by weight, the low-temperature stability of the gel composition began to deteriorate.

[0062]

[Table 4]

According to Table 4, when a fatty acid salt having a carbon number of more than 12 was blended, the hardness of the gel detergent composition in the portion having a low fatty acid content was slightly increased, and the fatty acid content was 30%.
A clear gel detergent having suitable hardness is obtained at ~ 34% by weight.

In the following examples, transparent gel detergents were prepared. Put all the ingredients listed in each recipe into the reactor,
The mixture was heated with stirring until clear dissolution was observed, and then cooled and taken out at 40 degrees. Each sample has good low-temperature stability, the feeling of use is quick to foam, there is a sense of volume,
The foam quality was fine and creamy.
