The order of mixing in producing the detergent is not particularly limited, but in the case of two or more kinds of surfactants, all the surfactants are first mixed and then other additives are mixed if necessary. The order of diluting with water at the end is preferable because mixing is easy in a short time.

When the cleansing agent of the present invention is used as a shampoo for washing off, a method of sprinkling the liquid cleansing agent on the animal as it is to wash it, or diluting the liquid cleansing agent with water in advance and applying it to the animal Cleaning method and mousse container in advance of liquid detergent (non-gas type container that can be ejected in a mousse shape by pumping up)
How to fill, and attach the mousse-like foam to the animal to wash,
Can be taken. Among these, the method is preferable in that the animal is not wet with the liquid, and that it is not necessary to wash while whipping by hand.

As a specific example of the method (1), the mousse is ejected from a mousse container filled with a cleaning agent (concentration: 13.8%), and the mousse is 1 to 10 per area of animal hair 10 × 10 cm.
An example is a method in which 2 g is applied, the whole body hair is made to fit with a brush or a comb and washed, and then rinsed with water (room temperature to lukewarm water).

The detergent of the present invention is preferably used in the above method even when it is used as a shampoo for wiping, and the concentration of the detergent is preferably 0.1 to 8 as described above.
When it is set to%, it is preferable because the labor and time for wiping off the excessive cleaning agent can be reduced. As a wiping method when used as a wiping shampoo, it can be wiped with a cloth such as a known towel or paper, but for wiping in a short time, use a cloth impregnated with an antifoaming agent. It is preferable to wipe off the bubbles adhering to the body hair while defoaming them.

As a specific example of the method of using as a shampoo for wiping off, a mousse is sprayed from a mousse container filled with a cleaning agent (concentration: 0.5%), and the mousse is 1 per 10 × 10 cm area of animal hair. Apply ~ 2g, and use a brush or comb to apply it to the whole body of hair and wash it, and then use a cloth (eg, non-woven fabric) impregnated with an antifoaming agent to absorb bubbles and water adhering to the hair of the animal. A method of (foaming, absorption) and wiping is exemplified.

As the defoaming agent that can be used for the defoaming agent-impregnated cloth, it is preferable to use a defoaming agent for food additives in consideration of the safety of animals and humans who perform washing. Antifoaming agents include lower alcohol type defoaming agents (methanol, ethanol, etc.), organic polar compound type defoaming agents (amyl alcohol, polypropylene glycol, etc.), mineral oil type defoaming agents (mineral oil surfactant blends) Etc.), silicone resin defoaming agents (silicone resin, silicone resin surfactant blended products, etc.), etc., and especially silicone defoaming agents include oil type (dimethyl silicone oil etc.) and compound type (silicone oil) In which fine powders such as silica and alumina are uniformly dispersed), emulsion type (such as a compound type defoaming agent using an emulsifier as an O / W type emulsion to improve dispersibility in water), Examples thereof include a solid type (a compound type defoaming agent, which is formed by heating and melting together with an emulsifier / thickener that is solid at room temperature). As for the type of cloth,
Nonwoven fabric (polyester, cotton, rayon alone or a mixture) can be used, and the size of the cloth is preferably 10 to 30 cm square, although it depends on the size of the animal. The defoamer impregnation amount is usually 0.005 to 10 based on the weight of the cloth.
%, Preferably 0.01 to 5%. In addition, the cloth may be disposable because the hair of the animal may come off when the cleaning agent is wiped off.

[Table 1]

<Viscosity> The viscosity at a liquid temperature of 25 ° C. was measured using a B type viscometer (type: BL, manufactured by Tokyo Keiki Co., Ltd.).

<Foaming property> Foaming property of only the cleaning agent: 20 ml of a 0.1% solids solution of the cleaning agent was put into a 100 ml graduated cylinder equipped with a stopper, and shaken by hand 50 times at 25 ° C. I will do it. Immediately after shaking and after standing for 5 minutes, the amount of foam (ml) is measured. Foamability of mixture of detergent and triolein: 5% of oil stain (triolein) is added to 20 cc of the above-mentioned detergent aqueous solution, and the same operation as above is performed.

<Stimulation> 50 pieces of white eggs of fresh chicken eggs are stirred and made uniform, and filtered by bleaching to remove impurities such as shells. 50 g of the white meat is placed in a beaker, and a detergent having a solid content of 0.075 g is added. Stir for 2 minutes with a magnetic stirrer and let stand for 1 minute, then measure the color difference (△ E) with the blank (white meat without detergent added) with a color difference meter (Nippon Denshoku Industries DICOM ND-504DE). .
The higher the value, the more cloudy and the greater the skin irritation.

<Dirt detergency> A test thread (100% wool thread) was used in place of animal hair to adhere dirt (animal dirt), and the weight of the test thread before and after washing was measured. Detergency was sought. 1 g of the test yarn is dried at 80 ° C. for 30 minutes, allowed to cool for 30 minutes, and then the weight (W0) is precisely weighed. Dissolve 0.05 g of animal dirt colored with Sudan III with 5 cc of dimethyl ether, air-dry for 1 to 1.5 hours after total impregnation treatment, dry at 80 ° C for 30 minutes, let cool for 30 minutes, then weigh (W1) Weigh accurately. Keep the aqueous detergent solution with a solid content of 0.3% warm at 30 ° C,
Set the test yarn and the cleaning agent aqueous solution in the shaking type cleaning device,
Wash for 3 minutes, then rinse with water in the same apparatus at 30 ° C. for 1 minute. The test yarn is dehydrated and air dried. After that, it is dried at 80 ° C. for 30 minutes, allowed to cool for 30 minutes, and then precisely weighed (W2). The detergency was calculated by the following formula. Since the dirt is colored with Sudan III, the degree of cleaning can be visually judged, and it was confirmed that there is a correlation with the above-mentioned cleaning power (%).

<Residual rate of linolenic acid> Evaluation was made in the same manner as in the above-mentioned evaluation method of detergency of dirt, except that linolenic acid dirt was used instead of animal dirt. However, the residual ratio (%) of linolenic acid was calculated by the following calculation formula.

<Defoaming property of bubbles> Three furs (moutons of a size of 20 × 10 cm to which linolenic acid stains are adhered) used in place of animal hair were prepared. 3 g of the cleaning agent S1 and the cleaning agent S2 of the present invention or the cleaning agent H1 of the comparative example (those diluted to a concentration of 0.5% and packed in a mousse container to form a mousse) are jetted on the above. The appearance of foaming at the time of jetting was visually judged. Then, using a comb, the entire fur is washed with a mousse-like cleaning agent. The state of foam retention (foam retention) during cleaning was visually evaluated. Then, defoaming agent [silicon compound type "SH-
5500 "(manufactured by Torre Dawkoning Silicone Co., Ltd.) was used to wipe the bubbles on the fur with a polyester non-woven fabric (15 cm × 15 cm), and the state after the wiping was visually determined. (Appearance of foaming) ○: Good foaming (many fine bubbles are generated) △: Slightly foaming (many fine bubbles are generated) (Appearance of foaming) ○: Good foaming (foam is mostly generated during washing with a comb) (Does not disappear) (State of defoaming) ◎: Defoamed (most of the foam has disappeared) ○: Almost defoamed (about 80% of the volume of the foam has disappeared) △: Slightly defoamed (approx. 60% of the volume of the foam has disappeared) x: Not very defoamed (about 50 of the volume of the foam)
(Only% or less disappears)

The cleaning agent for animals of the present invention is more effective than the conventional cleaning agent in cleaning soil components. Since the lipid component (linolenic acid) necessary for the hair of animals, especially pets, is easily left, it keeps good hair after washing. It is hypoallergenic to the skin of animals, especially pets and humans. Good foaming. Since it has a low viscosity, it can be used as a mousse. Even a low-concentration diluting liquid has excellent foaming properties, and is therefore suitable as a mousse-like cleaning agent for wiping. The foam can be easily wiped off by using a defoamer-impregnated cloth. Even if it is a low-viscosity diluent, it has excellent foaming properties,
By adjusting the concentration of the detergent, it can be appropriately used for a shampoo for washing off and a shampoo for wiping off, and any of them can be selected depending on the situation at the time of washing an animal, especially a pet.
