Description

Liquid detergent composition for former container {LIQUID DETERGENT COMPOSITION TO BE PACKED INTO FOAMER CONTAINERS}

The present invention relates to a liquid detergent composition, which has good foaming upon cleaning, particularly low skin irritation, excellent cold storage stability of the composition, and good clogging without causing clogging when filled in a foamer container. It relates to a liquid detergent composition capable of discharging bubbles.

It is desired for the cleaning composition to be excellent in the amount of foam and foam quality at the time of washing, and to be free of slipping after rinsing. In addition, it is also important for those with weak skin to have low skin irritation. In particular, liquid detergent compositions containing fatty acid as the main base are excellent in creamy properties compared to common surfactants, and can be washed clean without being slippery. Thus, cleansing agents, body soaps, and hand soaps are used. It is used for.

However, since the washing | cleaning composition containing a fatty acid salt tends to generate | occur | produce under low temperature storage, it is desired to be excellent in the low temperature storage stability of a composition.

On the other hand, the foaming agent is formed by filling a foamer container with a foamer container and passing the cleaning composition and air through a mesh at the same time, and the cleaner composition for foamer containers discharged is excellent in convenience. However, a liquid detergent composition containing a fatty acid salt as a periodic agent has a problem that precipitates are likely to occur due to low temperature or storage and, when filled in a foamer container, causes clogging of the mesh and makes it difficult to discharge bubbles.

In contrast, Patent Document 1 (Japanese Patent Application Laid-open No. Hei 8-92064) combines a salt such as a triethanolamine salt of one or two or more higher fatty acids with other salts, and a detergent for the purpose of improving usability at low temperatures. A composition is proposed. However, in this proposal, although the viscosity rise at low temperature can be suppressed, it is not enough to suppress the precipitate at the time of pH fall with time.

Patent Literature 2 (Japanese Patent Application Laid-Open No. Hei 8-143899) proposes a cleaning composition for the purpose of blending an amino acid surfactant and a higher fatty acid salt and improving the usability under low temperature. However, in this proposal, a refreshing rinsing texture characteristic of a fatty acid salt cannot be obtained, and similarly to Patent Document 1, it is not sufficient to suppress precipitates when the pH decreases with time.

Patent document 3 (Japanese Patent Laid-Open No. Hei 11-35972) proposes a cleaning composition containing a basic amino acid salt of a higher fatty acid, a positive or semipolar surfactant, and a polyhydric alcohol, and excellent in foaming and low temperature stability. However, in this proposal, although the precipitation of a fatty acid is suppressed by a positive or semipolar surfactant at the beginning of mixing | blending, it is desired to further suppress the precipitate when pH falls with time.

Patent document 4 (Patent No. 205-154651) proposes a cleaning composition which is excellent in low temperature stability without causing mesh clogging by mixing three kinds of higher fatty acid salts in a specific ratio. However, this proposal is also excellent in low temperature stability at the beginning of blending, but it is also desired to further suppress precipitates when the pH is lowered with time.

Patent Document 5 (Japanese Patent Laid-Open No. 2005-21323O) discloses a combination of a specific fatty acid composition, a neutralizing agent, and a specific high molecular compound so that bubbles can be easily discharged from a pump-former with only fatty acid soap without using a synthetic surfactant. There is a technique proposed. However, the activator is made of only fatty acid salts and no synthetic surfactant is used, so that precipitates are easily generated at low temperatures. From the above, even if the pH of the cleaning composition is lowered, generation of precipitates is suppressed, and a means for improving clogging of the former container is desired.

In addition, low temperature stability suppresses generation | occurrence | production of a precipitate and sedimentation over time under low temperature storage, even if pH of a liquid detergent composition falls.

(MEANS FOR SOLVING THE PROBLEMS)

MEANS TO SOLVE THE PROBLEM This inventor discovered that the precipitate when pH falls with low temperature and time-lapse | temporality was General formula (1), and R <^1> is a fatty acid salt of 12 or more monovalent hydrocarbon groups. Therefore, the acid dissociation exponent has a length in a specific carbon chain in fatty acids but the ratio is in a specific ratio, and in a liquid detergent composition containing a fatty acid salt and an amphoteric surfactant or a semipolar surfactant. By mixing the compounds of 8.0 to 11.0, it was found that even if the temperature is low but the pH of the cleaning composition is lowered, generation of precipitates is suppressed, the clogging of the foamer container can be improved, and discharged as bubbles. Moreover, the said detergent composition discovered that foaming at the time of washing | cleaning is good, and skin irritation is especially small, and it is early to achieve this invention.

It provides the liquid detergent composition for a foamer container as described in [1] which is a compound represented by these.

(Effects of the Invention)

According to the present invention, the foaming agent at the time of washing is good, the skin irritation is particularly low, the composition is excellent in the low temperature storage safety, and even when filled in the foamer container, the foaming agent liquid liquid detergent for foamer container is discharged without causing clogging. A composition can be provided.

(a) A component is a fatty acid salt represented by following General formula (1), It can be used individually by 1 type or in combination of 2 or more types.

R ¹ COOM ... (One)

(In formula, R <^1> represents the C5-C25 linear or branched monovalent hydrocarbon, and a part of hydrogen atom may be substituted by the hydroxyl group. M represents an alkali metal.)

R ¹ is a linear 5 to 25, preferably 7 to 17, more preferably 11 to 17 linear or branched monovalent hydrocarbon group, and may be saturated or unsaturated.

Examples of the component (a) include caproic acid, heptanoic acid, caprylic acid, pelargonic acid, capric acid, undecanoic acid, lauric acid, caprolein acid, undecylenic acid, lauroleinic acid, and 2-ethylbutanoic acid. Monovalent hydrocarbon group having 1 or less R ¹ in General Formula (1) such as isopentanoic acid, 2-ethylpentanoic acid, 2-ethylhexanoic acid, isononanoic acid, and 3,5,5-trimethylhexanoic acid Decanoic acid, tetramethylnonanoic acid, myristic acid, pentadecanoic acid, palmitic acid, stearic acid, arachinic acid, behenic acid, ligunoseric acid, seric acid, myristoleic acid, palmitoleic acid, oleic acid, ellidinic acid R ¹ in general formula (1), such as, gondophosphoric acid, erucic acid, ceracoreic acid, linoleic acid, linoleic acid, linolenic acid, 2-hexyldecanoic acid, isostearic acid, and 12-hydroxystearic acid, has 5 to 25 carbon atoms. Fatty acid salt which is a monovalent hydrocarbon group of is mentioned. Moreover, palm oil fatty acid, hardened palm oil fatty acid, palm oil fatty acid, hardened palm oil fatty acid, palm kernel oil fatty acid, hardened palm kernel oil fatty acid, tallow fatty acid, hardened tallow fatty acid etc. which are these mixtures are mentioned. Among these, lauric acid, myristic acid, palmitic acid, stearic acid, isostearic acid, oleic acid and palm oil fatty acids are preferable, and lauric acid, myristic acid and palm oil fatty acids are more preferable. Alkali metals, such as sodium and potassium, are mentioned as the paired salt, A potassium salt is preferable at the point of precipitation suppression. Amino acids are also widely used as salts for the pairing of fatty acids, but are not included since there is a fear of deterioration of the color tone and fragrance at the time of high temperature storage.

(a) the mass ratio represented by (formula (1) R ¹ is a monovalent hydrocarbon group up to 11 of the fatty acid salt) / (the general formula (1) R ¹ is 12 or more monovalent hydrocarbon fatty acid salt of a) of component Is 1.5 to 10.0, preferably 2.0 to 5.0, and more preferably 2.0 to 4.0. Fatty acid salts in which R ¹ is a monovalent hydrocarbon group of 12 or more are likely to be the main cause of precipitation, and are particularly remarkable when the pH is lowered or at low temperatures. This is a new discovery of the inventor. If the said mass ratio is less than 1.5, the cryopreservation stability of a composition and foam discharge | release property from a container will become inadequate. On the other hand, when it exceeds 10.0, there exists a possibility of skin irritation. In addition, the said numerical value rounds off the decimal point 2nd.

As for the compounding quantity of (a) component in a liquid detergent composition, 8-20 mass% is preferable as a fatty acid salt from the point of low temperature stability and foaming, More preferably, it is 8-15 mass%. If it is less than 8 mass%, foam quality may become inadequate, and when it exceeds 20 mass%, the viscosity of a composition may rise and foam may not be discharged easily from a foamer container.

As phosphobetaine-type amphoteric surfactant, lauryl hydroxy phosphobetaine etc. are mentioned. Examples of the imidazoline type amphoteric surfactant include palm oil alkyl-N-hydroxyethyl imidazolinium betaine.

Examples of the acyl tertiary phosphon oxide include lauryl dimethyl phosphon oxide and the like.

Among these, carbobetaine-type amphoteric surfactant and lauryldimethylamine oxide are preferable from a viewpoint of improving foamability etc., and lauryldimethylaminoacetic acid betaine is preferable among carbobetaine types. In addition, lauryl dimethylamine oxide is preferable because the viscosity slightly increases at low temperature and the foaming discharge from the foamer container becomes good. In addition, the sodium chloride contained in the preparation of the synthetic activator may promote the precipitation of fatty acids, more preferably desalted from the viewpoint of improving low temperature stability, and the sodium chloride concentration in the liquid detergent composition is O. It is preferable that it is 0O1 mass% or less.

As for the compounding quantity of (b) component in a liquid detergent composition, 0.1-5 mass% is preferable, More preferably, it is 0.5-3 mass%. If it is less than 0.1 mass%, the improvement of low temperature stability may become inadequate, and when it exceeds 5 mass%, there exists a possibility that slipperiness may occur at the time of rinsing. The mass ratio represented by (a) / (b) is preferably from 50/1 to 5/1 in view of low temperature stability.

(c) A component is a compound whose acid dissociation index is 8.0-11.0, and can be used individually by 1 type or in combination of 2 or more types. In addition, an acid dissociation index is -log [acid dissociation constant] and an acid dissociation constant is measured at 25 degreeC. Examples of the compound having an acid dissociation index of 8.0 to 11.0 include monoethanolamine, diethanolamine, ethylamine, 2-amino-2-hydroxymethyl-1,3-propanediol, 3-amino-1-propanol, 2-amino-2 -Methyl-1-propanol, 2-amino-2-methyl-1,3-propanediol, isopropanolamine, isopropylamine, etc. are mentioned.

Preferred are amines, ethylamines and isopropanolamines.

0.3-3 mass% is preferable, and, as for the linear chain of (c) component in a liquid detergent composition, More preferably, it is 0.5-1 mass%. If the content is less than 0.3%, the low temperature stability may be insufficient. If the content exceeds 3% by mass, the color tone and the smell may be deteriorated.

The liquid detergent composition of this invention is for a foamer container, and is for filling a foamer container filled into a foamer container. Moreover, it can be set as the liquid detergent composition product provided with the liquid detergent composition and the foamer container which filled this. The former container is a non-gas type foam discharge container. The non-gas type foam discharge container is not particularly limited as long as the liquid detergent composition can be discharged in a foamed state by mixing the liquid detergent composition. For example, a squeeze foamer capable of discharging bubbles by pressing the bottle body by hand.
