Description

  The present invention relates to a liquid cleaning composition, specifically a liquid cleaning composition suitable for use in a kitchen for cleaning dishes and the like.

A liquid detergent composition for kitchens mainly intended for washing dishes generally includes an anionic surfactant and an amphoteric surfactant, and exhibits a cleaning effect by the synergistic effect of these surfactants. . In recent years, in order to improve detergency, it has been studied to add alkanesulfonic acid or a salt thereof, for example, secondary alkanesulfonic acid or a salt thereof as an anionic surfactant (Patent Document 1).
If such a liquid detergent composition is left in contact with the atmosphere for a long time, a film may be formed on the surface thereof. In order to prevent the formation of such a film, a component for preventing the formation of the film, such as polyalkylene glycol, is usually added to the liquid detergent composition.
However, when alkanesulfonic acid or a salt thereof is blended with polyalkylene glycol, the polyalkylene glycol is precipitated at a low temperature, causing a problem of causing turbidity in the liquid detergent composition.

JP 2008-156589 A

  The present invention provides a liquid cleaning agent that improves the detergency by containing alkanesulfonic acid and / or a salt thereof, particularly secondary alkanesulfonic acid and / or a salt thereof, and forms a film or suppresses the occurrence of turbidity. An object is to provide a composition.

  ADVANTAGE OF THE INVENTION According to this invention, the washing | cleaning power is improved by containing a secondary alkanesulfonic acid, At the same time, the liquid cleaning composition excellent in storage stability which suppressed generation | occurrence | production of a film | membrane and turbidity can be provided.

(A) Polyoxyethylene alkyl ether sulfate salt The alkyl group of the alkyl ether portion of the polyoxyethylene alkyl ether sulfate salt is preferably an alkyl group having 8 to 18 carbon atoms, more preferably 10 to 16 carbon atoms, The average number of moles added of the oxyethylene group is preferably 0.1 to 5, more preferably 0.3 to 4. Outside these ranges, the detergency may be reduced and storage stability may be impaired. The addition molar distribution of the polyoxyethylene group may be either a narrow distribution or a wide distribution as disclosed in JP-A-2001-172698, but from the viewpoint of low-temperature stability, a distribution with a narrow distribution width may be used. desirable.
In the polyoxyethylene group in the component (A), a polyoxyethylene alkyl ether sulfate ester salt in which the distribution of the number of added moles of ethylene oxide is 55% or more as defined by the following formula is more preferable. When the narrow rate is 55% or more, preferably 60% or more, more preferably 70% or more, the low temperature stability of the composition becomes better. The narrow rate is a numerical value representing the distribution width of the addition molar distribution of the polyoxyethylene group of the obtained polyoxyalkyl ether sulfate ester salt. It means that the width of the addition mole distribution of the polyoxyethylene group is narrower as the narrow ratio is higher.
Narrow ratio _{= Y max-2 + Y max} -1 + Y max + Y max + 1 + Y max + 2
(Here, the percentage number of moles is i of ethylene oxide and Y _i, based on the total amount of the polyoxyethylene alkyl ether sulfate, a maximum value of Y _i is taken as a Y _max,
The value of the number of moles of ethylene oxide added when Y _i takes Y _max is n _max ,
n is the value of Y _i when an (n _max -2) and Y _max-2,
The value of Y _i when n is (n _max −1) is Y _max−1 ,
The value of Y _i when n is (n _max +1) is Y _{max + 1} ,
The value of Y _i when n is (n _max +2) is Y _{max + 2} .
However, when n _max −2, n _max −1 or n _max is zero, Y _max−2 , Y _max−1 or Y _max is not counted. )
