Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a detergent composition. More specifically, the present invention relates to a cleaning composition that can be used stably for a long period of time by preventing the cleaning composition filled in a container with a nozzle from solidifying and clogging at the nozzle outlet.

2. Description of the Related Art In recent years, liquid detergent compositions such as shampoos, rinse-in shampoos, body shampoos, hand soaps, and face washes are provided in a container with a nozzle provided with a pump part or a body part made of a flexible member. Many are filled and provided to consumers. These containers can be easily taken out of the required amount of content simply by pushing from the top of the pump or the body, and it is easy to use, but if the filled content is easily solidified, the pump will not operate. Also, if it is easy to dry, it usually dries at the nozzle outlet, and the one with no fluidity accumulates, the outlet becomes thin and the contents do not come out easily, it pops out in an unexpected direction, or the outlet is closed There are problems such as things getting out.

Conventionally, various methods have been considered for preventing the surface portion of the liquid detergent from drying and preventing such clogging of the detergent composition to be filled in the nozzle-equipped container. For example, a film-free liquid detergent using an alkyl ethoxy sulfate salt and polyethylene glycol (JP-A-53-92809), a sugar ester surfactant and polyethylene glycol are contained to prevent film formation during storage. Liquid detergent composition (JP-A-03-174497)
No.), water and a water-soluble organic solvent such as propylene glycol and glycerin, and black iron oxide having a specific particle size, and a liquid cosmetic which does not cause clogging with time (JP-A-1-13952).
No. 1), iron oxide having a specific particle size, a polymer dispersant, a water-soluble organic solvent such as propylene glycol and glycerin, and a liquid cosmetic which does not cause clogging (Japanese Patent Application Laid-Open No. 1-19
No. 3210) and the like are known.

[0004]

However, even if these conventionally known detergent compositions are filled into a container with a nozzle and used, the effect cannot be sufficiently exhibited. For example, a liquid detergent using a surface active agent such as an alkyl ethoxy sulfate ester salt or a sugar ester-based surface active agent and polyethylene glycol has a drawback that the viscosity of a compounded product is remarkably reduced. Liquid cosmetics that use iron and a water-soluble organic solvent such as propylene glycol and glycerin have poor stability,
The properties and performance of the product cannot be maintained, and clogging cannot be prevented without changing these.

The present invention has been made by paying attention to the above points, and prevents the cleaning agent composition filled in the nozzle-equipped container from being solidified and clogged at the nozzle outlet, and can be used stably for a long period of time. It is an object of the present invention to provide a cleaning composition that can be used.

[0006]

Means for Solving the Problems The inventors of the present invention have conducted extensive studies to solve the above problems, and as a result, by using an alkylene oxide adduct of glycerin or diglycerin, a detergent composition filled in a nozzle-equipped container is used. The inventors have found that the solidified material does not solidify and the nozzle outlet is not clogged, and that it can be used stably for a long period of time, thus completing the present invention.

That is, the present invention provides a detergent composition filled in a container with a nozzle, which contains 0.1 to 10% by weight of a glycerin or diglycerin 5 to 60 mol alkylene oxide adduct. It is a composition.

The detergent composition of the present invention is suitable for filling and providing in a container with a nozzle. What is a container with a nozzle?
A container provided with a hollow portion capable of filling the cleaning composition and a narrow outlet like a nozzle. A container in which a filler can be taken out from the nozzle by a nozzle that is operated by pushing a pushing portion with a hand, and the hollow portion is made a flexible member. Examples of the container include a container that can press the part to take out the filling from the nozzle, a container that can fill the cavity with air, liquefied gas, and the like, and pressurize with these to take out the filling from the nozzle.

The detergent composition of the present invention is based on a known detergent component that is provided by filling a container with a nozzle, and further contains the alkylene oxide adduct of glycerin or diglycerin. It is preferable that the content of the alkylene oxide adduct of glycerin or diglycerin contained in the detergent composition is 0.1 to 10% by weight, because the effect of preventing clogging is excellent without particularly changing other physical properties. If the content of the alkylene oxide adduct of glycerin or diglycerin in the detergent composition is less than 0.1% by weight, the effect of preventing clogging is insufficient and solidification occurs at the nozzle outlet during use, and 10% by weight. Bubbles when crossing
This is not preferable because it causes problems such as affecting viscosity and compatibility.

The alkylene oxide adduct of glycerin or diglycerin is a compound in which alkylene oxide is added to glycerin or diglycerin, and alkylene oxide such as ethylene oxide or propylene oxide is solely added to glycerin or diglycerin according to a conventional method. Alternatively, it is possible to use the one obtained by adding both of them in a block shape or a random shape.
The amount of alkylene oxide added to glycerin or diglycerin is preferably 5 to 60 mol per 1 mol of glycerin or diglycerin, and the alkylene oxide adduct in this range has no influence on foaming, viscosity and compatibility. It effectively prevents clogging. If the amount of alkylene oxide added to glycerin or diglycerin is less than 5 mol, the effect of preventing clogging is not sufficient, and if it exceeds 60 mol, the viscosity is greatly affected and the viscosity of the detergent composition is lowered. . If the viscosity of the detergent composition filled in the nozzle-equipped container is low, it tends to spill when used, when picked up on hands, towels, sponges, etc., and also when other ingredients such as pearling agents are blended. The stability of is likely to decrease, which is not preferable.

The detergent composition of the present invention may contain, in addition to the alkylene oxide adduct of glycerin or diglycerin, a conventionally known detergent component filled in a container with a nozzle. For example, as a component that can be blended, fatty acid soap, amide ether sulfate, alkyl ether sulfate, alkyl sulfate, alkane sulfonate, α-olefin sulfonate, sulfosuccinate, N-methylalanine, N-methyltaurine. , N-methylsarcosine, anionic surfactants such as acylated glutamate, amphoteric surfactants such as alkyl betaine, amidobetaine, imidazolinium betaine,
Thickeners such as alkanolamides and polyethylene glycol distearate, foam stabilizers such as alkanolamides, conditioning agents such as cationized cellulose, highly polymerized silicone, animal and plant extracts, pearling agents such as ethylene glycol distearate, etc. Examples include shampoos, rinse-in shampoos, body shampoos, hand soaps, and detergent components for facial cleansing, which are based on known additives.

Hereinafter, the present invention will be described in more detail by way of examples, but the present invention is not limited to these as long as the gist thereof is not exceeded. Hereinafter, "%" represents "% by weight".
