DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a detergent composition, and more particularly to a detergent composition containing at least one salt of a higher fatty acid and also containing water. It is semi-solid or solid within a predetermined temperature range substantially determined by the type of higher fatty acid salt contained in the composition and the content thereof, and softens, liquefies and flows when cooled below the predetermined temperature range. The present invention relates to a novel detergent composition having specific temperature-sensitive properties (temperature sensitivity) in which the property is enhanced.

2. Description of the Related Art Conventionally, solid, powder, jelly,
Detergents with various shapes such as cream paste, lotion, liquid, and aerosol have been developed and marketed. Kitchen dishwashing detergents, shampoos, clothing detergents, other residential detergents, cleaning detergents, automotive detergents, etc. Has been used as

In particular, among these known cleaning agents, those which are liquid or semi-solid (paste) at room temperature tend to be frequently used recently because of their excellent usability. As a liquid detergent raw material, a higher fatty acid salt having 8 to 20 carbon atoms is used in terms of detergency, easy dephosphorization, compatibility, easy dissolution, low-temperature stability (cold resistance), and rinsing. However, any detergent containing a higher fatty acid salt alone or a mixture of two or more of these higher fatty acids as a main component loses its fluidity when cooled, and hardens or undergoes a phase transition to a solid phase. On the other hand, there is no known material which is opposite to the conventional one, in which its fluidity is enhanced upon cooling, and is softened or liquefied.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to provide a novel detergent composition containing at least one salt of a higher fatty acid and also containing water. Has a semi-solid or solid stable shape at room temperature without losing force, non-phosphorusability, compatibility, easy dissolution, low temperature stability (cold resistance), bubble elimination, rinsing, etc. On the other hand, it is an object of the present invention to provide a detergent composition having a unique temperature-sensitive property (temperature-sensitive property), which has not been seen in the past, such that when it is cooled, it softens and liquefies to obtain or enhance fluidity. .

It is another object of the present invention to provide a highly safe cleaning composition which is completely decomposed by hydrolysis or biodegradation by microorganisms in the soil when left in the natural world.

Further, when the detergent composition is solidified in the container, the detergent composition is solidified in a state in which bubbles are contained so that the average density is less than 1 g / cm ³ , whereby water or water is contained together with the container. Being floatable in hot water is another purpose.

Here, the term "semi-solid" means a solid state in which fluidity is lost, including a state called a gel state or a jelly state, and the "phase transition temperature" refers to a liquid phase. A temperature or a temperature range at which a phase transition from (liquid) to a solid phase (semi-solid or solid) reversibly is defined.

As described above, the detergent composition according to the present invention provides, for example, a detergency, a non-phosphorus-free property, and a compatibility which a conventional detergent mainly containing a naturally-occurring higher fatty acid salt exerts. In addition to excellent functions and effects such as easy dissolution, low temperature stability (cold resistance), bubble elimination and rinsing, the following special functions and effects are exhibited.

First, each of the detergent compositions of the present invention is prepared by blending a potassium salt of a naturally occurring higher fatty acid, and when left in the natural world, it undergoes hydrolysis or biodegradation by microorganisms in the soil. Since it is completely decomposed, it does not cause environmental destruction, etc., and is excellent in safety.

Next, since the cleaning composition of the present invention has been improved so as to be in a liquid state when cooled, the cleaning composition can be easily made into a liquid state by, for example, cooling with water after adjusting the cleaning composition. Therefore, the energy efficiency when packing them in the bag can be improved, and the work efficiency of the filling operation can be improved. That is, labor costs can be reduced, and capital investment costs can be reduced.

Further, even if a bag having a small pinhole is filled with the cleaning composition of the present invention, it can be quickly solidified if left at room temperature, so that the yield of the product is significantly improved. be able to.

Next, since the detergent composition after packing is solid at room temperature, the adhesive is dissolved by the detergent composition while these are stored. Alternatively, the package does not break or break due to the fact that the cleaning composition permeates the heat-sealed joint surface and the joint surface peels off. Even if the package breaks due to physical impact during storage or transportation, it does not leak like a liquid detergent.

Further, since the phase can be changed to a liquid state by cooling with cold water such as tap water, it can be easily taken out of the package or the packaging container, and the usability can be improved.

Furthermore, the cleaning composition of the present invention has a semi-solid or solid stable shape at room temperature, but when cooled, it softens and liquefies. Since it has a unique temperature-sensitive property (temperature-sensitivity), even if the fragrance is decomposed or combined by heating to lose or reduce its effect, for example, the cleaning composition is cooled. The flavoring agent can be surely mixed while the mixture is in a liquid state. In addition, it is possible to stabilize the volatilization efficiency of the fragrance component due to a temperature change during use and the effect thereof.

Next, it is colored with a colorant in a beautiful color, and a large number of fine bubbles are built into the pumice so that the apparent average density is about 0.9 g / cm ^3. The cleaning composition packed in a thin, flexible synthetic resin bag can be floated in hot water of a bath, and has a beautiful and beautiful appearance.
