Detergent composition for hand washing laundry

The present invention relates to a detergent composition for hand-washing laundry that allows a cool feeling to be perceived quickly and a method for producing the same.

BACKGROUND ART There are two types of washing methods: hand washing and washing machine washing. In recent years, there has been a tendency for washing by washing machines to increase due to the widespread use of washing machines. However, from the viewpoint of removing dirt and economy, hand washing is still performed.

Compared to washing with a washing machine, hand-washing allows fine washing depending on the situation, such as the degree of dirt removal and the type of object to be washed. In some cases, sweating and uncomfortable work was accompanied by physical and mental fatigue. In addition, “rubbing”, which rubs the objects to be cleaned, is one of the most natural hand-washing methods because it is easy to apply mechanical force to the parts to be cleaned. Become. As a result, the feeling of wanting to finish it quickly was reached, and as a result, the removal of dirt sometimes ended inadequately. Therefore, a comfort that eliminates the feeling of fatigue has been demanded for hand washing.

DETAILED DESCRIPTION OF THE INVENTION International Publication No. WO 01/034753 The specific examples of this publication only describe the effect of methyl lactate, and when the methyl lactate is replaced with menthol, the cool feeling is felt too much. I can't.
Japanese Patent Application Laid-Open No. 2004-269368 and Japanese Patent Application Laid-Open No. 11-092327 disclose cosmetic compositions using menthol and camphor together, but all of them are only descriptions of techniques for suppressing irritation unique to menthol.

In hand-washing, it is possible to give comfort and enjoyment to the worker, especially depending on the surrounding environment, by giving the worker a cool feeling. As the cooling agent, use of menthol having the highest versatility and safety is preferable. However, since hand-washing usually uses a large amount of water relative to the weight of the clothing, the menthol concentration in the washing bath solution is diluted. For this reason, it is difficult for the worker to perceive a noticeable cooling sensation due to the characteristic of menthol, or it takes a long time to feel the cooling sensation. Also, in actual hand-washing and washing sites, take clothes out of the washing bath immediately after starting, and take your hands out of the washing bath for several minutes, such as scrubbing or brushing with a washboard. In general, a sensitivity that can perceive a cool feeling, that is, a decrease in the perceived sensitivity of the cool feeling cannot be avoided.

From the actual situation of such hand-washing washing methods, when washing laundry with hand-washing laundry detergent that contains only menthol as a cooling agent, it is not only difficult for workers to perceive a noticeable cooling feeling, but also expects. It is known that comfort and enjoyment are greatly impaired.

The present invention provides a detergent composition for hand-washing laundry that quickly perceives coolness, a manufacturing method thereof, and a hand-washing washing method using the washing liquid.

The contained washing liquid can be used. In the washing liquid, the concentration of the component (a1) is preferably 10 ppm or more.

The present invention relates to a technology capable of quickly perceiving a menthol cooling feeling in a very short time when hand-washing clothes (objects to be washed) in contact with a washing liquid containing a powder detergent composition for clothes. The effect of the present invention is greatly exerted in a very hot environment in which the average monthly maximum temperature exceeds 30 ° C. throughout the year represented by Thailand and Indonesia, which are tropical climates. Hand washing of a large amount of clothing (objects to be washed) under such intense heat is heavy labor, and it is particularly a harsh operation to perform hand washing for a long time, for example, 30 minutes or more. Also, under high temperature environment, the worn clothing gets wet and feels uncomfortable in daily life, so it is often changed several times during the day, which is proportional to the increase in clothing (objects to be washed). At present, the feeling of fatigue is amplified.

The amount of water that can be fully submerged in a general household, such as two adults in their 20s to 40s and two to three minors in their ages 0 to 10 after daily wear, is about About 10 to 20 L is necessary, and usually large raisins and buckets corresponding to the amount of water are used for hand-washing. Even if the dimensions are small, the diameter is 40 cm and the depth is 20 cm or more, and when the dimensions are large, the diameter reaches 60 cm and the depth is 20 cm.

The appropriate amount of the powder detergent composition for clothing according to the amount of water has different sensations depending on the person, but for example, about 35 g to 45 g is used for a laundry detergent exclusively for hand washing with respect to about 10 L of water. It is an approximate guide because what is recommended is sold.

Hand-washing has such an actual situation, and in particular, it is very hard work to wash the items to be washed in a high-temperature environment such as in the tropics. However, the menthol is made by the powder detergent composition for clothing of the present invention. By quickly perceiving a cool feeling in a short time, the feeling of fatigue can be greatly reduced.
