Description

  The present invention relates to a liquid detergent for textile products.

Two types of cleaning agents for textile products whose clothing is to be cleaned are generally powder cleaning agents and liquid cleaning agents. The demand for liquid detergents has been increasing because there is no concern about undissolved residue and because it can be applied to clothing and the like.
In recent years, with a growing awareness of environmental impact, reductions in transportation costs, waste reduction, and the like have been demanded. For this reason, a liquid cleaning agent has been proposed in which the resin container is made compact by increasing the content of the cleaning component (concentration) and the environmental load is reduced. However, when the liquid detergent is simply concentrated, the fluidity is impaired or the gel is partially gelled (liquid stability is low).
In order to solve this problem, a liquid detergent containing a specific nonionic surfactant, an anionic surfactant, and a water-miscible organic solvent has been proposed (for example, Patent Document 1). According to the invention of Patent Document 1, the cleaning power and the liquid stability are improved.

By the way, in recent years, some liquid cleaning agents have improved texture improvement effect in addition to excellent cleaning power for cleaning objects.
For example, a liquid detergent containing a specific nonionic surfactant, a tertiary amine, a water-soluble silicone, and a specific anionic surfactant has been proposed (for example, Patent Document 2). According to the invention of Patent Document 2, it is intended to impart flexibility and improve liquid stability.

The liquid detergent for textile products of the present invention (hereinafter sometimes simply referred to as liquid detergent) comprises a specific nonionic surfactant (A) (component (A)) and a specific compound (B) ((B ) Component) and glycol solvent (C) (component (C)).

<(A) component>
The component (A) is a nonionic surfactant represented by the following general formula (1). A liquid detergent can exhibit the outstanding detergency by containing (A) component. In addition, the component (A) can impart flexibility to the object to be cleaned.

  [In the formula (1), R represents a hydrocarbon group having 10 to 20 carbon atoms. EO is an oxyethylene group and PO is an oxypropylene group. s represents the average number of repetitions of EO and is a number from 5 to 20, and t represents the average number of repetitions of PO and is a number from 1 to 4. ]

(1) In the formula, the hydrocarbon group of R may be linear or branched, or may contain a cyclic structure. R is preferably an aliphatic hydrocarbon group, more preferably a linear or branched alkyl group, or a linear or branched alkenyl group.
Carbon number in the hydrocarbon group of R is 10-20, 12-18 are preferable and 12-14 are more preferable. If the carbon number of R is not less than the above lower limit, the detergency increases. If the carbon number of R is not more than the above upper limit, the liquid stability is improved, and particularly gelation is suppressed.

  The component (A) may consist of only R having a single chain length, or a mixture of R having a plurality of chain lengths. R is derived from a raw material alcohol (R—OH), and examples of the alcohol include alcohols derived from natural fats and oils such as palm oil, palm oil, and beef tallow, and synthetic alcohols derived from petroleum.

(1) In formula, s shows the average repeating number of EO (oxyethylene group). That is, s is the average number of moles of ethylene oxide added. s is a number from 14 to 50, preferably 16 to 30, and more preferably 16 to 25. When s is within the above range, the cleaning power of the liquid cleaning agent, particularly the cleaning power against sebum dirt is improved.
t represents the average number of repetitions of PO (oxypropylene group). That is, t is the average added mole number of propylene oxide. t is a number of 1-5, and 2-4 are preferable. When t is in the above range, gelation of the liquid detergent is likely to be suppressed, and good foaming properties are easily obtained at the time of rinsing.
(1) In the formula, EO and PO may be added in a block shape or may be added in a random shape. When EO and PO are added in the form of a block, the addition method includes adding ethylene oxide followed by propylene oxide, adding propylene oxide followed by ethylene oxide, and adding ethylene oxide followed by propylene oxide. And a method of adding ethylene oxide. In particular, since rinsing properties in washing in a fully automatic washing machine are better, a method of adding propylene oxide after adding ethylene oxide and further adding ethylene oxide (the terminal is —O—CH ₂ CH ₂ O—H). Is preferred).

In the component (A), the distribution of the added mole number of the alkylene oxide is not particularly limited, and the added mole number distribution can be controlled by the production method of the component (A) and the like.
For example, when an alkylene oxide is added to a hydrophobic raw material using a general alkali catalyst such as sodium hydroxide or potassium hydroxide, a relatively wide addition mole number distribution tends to be obtained. Further, specific alkoxyl such as magnesium oxide to which metal ions such as Al ³⁺ , Ga ³⁺ , In ³⁺ , Tl ³⁺ , Co ³⁺ , Sc ³⁺ , La ³⁺ , Mn ^{2+ and the} like described in JP-B-615038 are added. When alkylene oxide is added to a hydrophobic raw material using a catalyst, it tends to have a relatively narrow addition mole number distribution.

The method of using the liquid cleaning agent (cleaning method) is the same as the method of using a general liquid cleaning agent. For example, a method in which a liquid cleaning agent is put in water together with an object to be cleaned and washed in a washing machine, a method in which a liquid cleaning agent is directly applied to an object to be cleaned, a liquid cleaning agent dissolved in water to form a cleaning liquid, and the cleaning liquid For example, a method of immersing the cleaning object is used. Moreover, after apply | coating a liquid cleaning agent to a to-be-washed object and leaving it to stand suitably, you may wash | clean using a washing machine etc.
Examples of the textile product to be cleaned include textile products such as clothing, cloths, sheets, and curtains, among which clothing is preferable.

As described above, according to the liquid cleaning agent of the present invention, a dry tactile sensation is given to the object to be cleaned without impairing the flexibility of the object to be cleaned, and the liquid stability is good.
The reason why the effects of the present invention can be obtained by containing the components (A) to (C) is not clear, but is estimated as follows.
(B) The dry tactile sensation can be provided to a to-be-cleaned object because a component adheres to a to-be-cleaned object. Here, since the component (A) has PO, it is relatively highly hydrophobic. For this reason, it is thought that the adhesion amount of the (B) component with respect to a to-be-cleaned object is increasing by interposing (A) component.
In addition, since the component (C) is contained as a solvent, the liquid stability is increased.
