JP5071687B2 - Liquid detergent composition for former container - Google Patents

Description

  The present invention relates to a liquid detergent composition, good foam quality at the time of washing, particularly low skin irritation, excellent low-temperature storage stability of the composition, good without clogging when filled in a former container The present invention relates to a liquid detergent composition capable of discharging a foam.

  It is desired that the cleaning composition is excellent in the amount of foam and the quality of the foam at the time of cleaning, and does not have a sliminess after rinsing. It is also important that people with weak skin have little skin irritation. Among them, liquid detergent compositions based on fatty acid salts are superior in foam creaminess compared to general surfactants, and do not feel slippery, so they can be washed cleanly. Used in soaps.

  However, since the detergent composition containing a fatty acid salt is likely to precipitate under low temperature storage, a composition having excellent low temperature storage stability of the composition has been desired.

  On the other hand, the foam composition is filled by filling the liquid container with the liquid detergent composition and the detergent composition and the air are simultaneously passed through the mesh. Yes. However, liquid detergent compositions based on fatty acid salts tend to generate precipitates due to low temperature and storage, and when filled into a former container, clogging of the mesh occurs and bubbles are difficult to be discharged. There was a problem.

  On the other hand, Patent Document 1 (JP-A-8-92064) contains a salt such as a triethanolamine salt of one or more higher fatty acids and other salts, and is usable at low temperatures. A cleaning composition aimed at improving the above has been proposed. However, although this proposal can suppress an increase in viscosity at low temperatures, it is not sufficient to suppress precipitates when the pH decreases with time.

  Patent Document 2 (Japanese Patent Laid-Open No. 8-143899) proposes a cleaning composition containing an amino acid surfactant and a higher fatty acid salt for the purpose of improving usability at low temperatures. . However, this proposal does not provide a refreshing rinsing feel that is characteristic of fatty acid salts, and, like Patent Document 1, is not sufficient to suppress precipitates when the pH decreases with time.

  Patent Document 3 (Japanese Patent Application Laid-Open No. 11-35972) contains a basic amino acid salt of a higher fatty acid, an amphoteric or semipolar surfactant, and a polyhydric alcohol, and has excellent foam quality and low-temperature stability. Compositions have been proposed. However, in this proposal, the amphoteric or semipolar surfactant suppresses the precipitation of fatty acid at the initial stage of blending, but it has been desired to further suppress the precipitate when the pH is lowered with time.

  Patent Document 4 (Japanese Patent Application Laid-Open No. 2005-154651) discloses a cleaning composition that does not cause clogging of the mesh and is excellent in low-temperature stability by mixing three kinds of higher fatty acid salts at a specific ratio. Proposed. However, although this proposal is also excellent in low-temperature stability at the initial stage of blending, it has been desired to further suppress precipitates when the pH decreases with time.

  Patent Document 5 (Japanese Patent Application Laid-Open No. 2005-213230) discloses a pump former that uses only a fatty acid soap without using a synthetic surfactant by combining a specific fatty acid composition with a neutralizing agent and a specific polymer compound. A technology that can easily discharge bubbles is proposed. However, only the fatty acid salt is used as the activator and no synthetic surfactant is used, and precipitates are easily generated at low temperatures. From the above, there has been a demand for a means for suppressing the occurrence of precipitates and improving the clogging of the former container even when the pH of the cleaning composition is lowered.

  The present invention has good foam quality at the time of washing, particularly little skin irritation, excellent low-temperature storage stability of the composition, and can discharge good foam without clogging when filled in a foam container. It aims at providing the liquid detergent composition for former containers. In addition, low temperature stability is suppressing generation | occurrence | production of the precipitate and precipitation with time under low temperature preservation | save, even if pH of a liquid detergent composition falls.

The present inventor has found that the precipitate when the pH is lowered due to low temperature or aging is a fatty acid salt in which R ¹ is a monovalent hydrocarbon group of 12 or more in the general formula (1).

Furthermore, the above-mentioned cleaning composition has been found to have good foam quality at the time of cleaning and to have particularly little skin irritation, and has led to the present invention.

  According to the present invention, the foam quality at the time of washing is good, the skin irritation is particularly low, the composition is excellent in low-temperature storage stability, and good foam is discharged without clogging even when filled in a former container. A liquid detergent composition for a former container can be provided.

Among these, lauric acid, myristic acid, palmitic acid, stearic acid, isostearic acid, oleic acid, and coconut oil fatty acid are preferable, and lauric acid, myristic acid, and coconut oil fatty acid are more preferable. Examples of the salt as a pair include alkali metals such as sodium and potassium, and potassium salts are preferable from the viewpoint of suppressing precipitation. Amino acids are also widely used as the fatty acid pair salts, but they are not included because there is concern about the deterioration of the color tone and fragrance during storage at high temperatures.

The mass ratio represented by (fatty acid salt) is 1.5 to 10.0, preferably 2.0 to 5.0, more preferably 2.0 to 4.0. Fatty acid salts in which R ¹ is a monovalent hydrocarbon group of 12 or more tend to be the main cause of precipitation, particularly when pH is lowered or at low temperatures. This is a new finding of the present inventors. If the mass ratio is less than 1.5, the composition is not sufficiently stable at low temperature storage and foam ejection from the container. On the other hand, if it exceeds 10.0, there is a concern of skin irritation. The above numbers are rounded off to the second decimal place.
