Description

  The present invention relates to a liquid detergent composition, and more particularly to a liquid detergent composition suitable for hand-washing laundry.

  There are two types of washing methods for clothing and the like: hand washing and washing machine washing. In recent years, there is a tendency for washing machines to increase due to the spread of washing machines. However, from the viewpoint of being able to confirm the degree of dirt removal and economical efficiency, hand washing is still widely performed worldwide. Yes. In particular, hand-washing laundry is often adopted so that it can be washed with as little water as possible in an area where water resources are low. On the other hand, large household items such as sheets are unsuitable for hand-washing, so many households use both hand-washing and washing machine washing.

  In both hand-washing and washing-machine washing, it is important to control foaming when washing and too much foaming when washing too much. For example, the amount of foam generated during washing of clothes, etc., is a factor that causes a sense of fulfillment and security that washing is sufficient for consumers who do laundry, Foam residue can also cause anxiety. Especially in the case of hand washing, some people increase the number of rinses if there is foam residue. Even in the case of washing with a washing machine, there are some people who show intense disgust or increase the number of times of rinsing with respect to the remaining foam during rinsing.

  In addition, in laundry such as clothing, in recent years, awareness of hygiene and cleanliness has increased, and functions such as deodorization and deodorization are required in addition to the original functions such as removal of dirt. Here, the deodorizing function refers to a function that suppresses unpleasant odor that occurs when the humidity is high and the laundry is difficult to dry. The excellent deodorizing function means, for example, that it does not cause unpleasant odors, does not feel unsanitary, does not feel anxious odors, even if it is in a bad environment such as a rainy day or indoors. When blended, it leads to a more hygienic feeling such as enjoying a good scent.

  In Patent Document 1, a liquid detergent composition containing a nonionic surfactant, a cationic surfactant, a hydrotrope agent, hydrogen peroxide, and a water-miscible solvent under predetermined conditions is used after washing clothes and the like. It is disclosed that a raw dry odor can be suppressed.

  Patent Document 2 discloses an injectable liquid laundry detergent composition containing a surfactant such as sodium alkyl ether sulfonate, sodium alkylbenzene sulfonate, sodium alkyl sulfonate, and the like.

  Patent Document 3 discloses a polyoxyalkylene alkyl ether type nonionic surfactant having a relatively large average number of added moles of alkyleneoxy groups, a specific anionic surfactant, and a fatty acid having 8 to 18 carbon atoms or a salt thereof. It is disclosed that the cleaning composition contained under specific conditions is excellent in cleaning power and foaming property at the time of cleaning, and the foam disappears quickly in the rinsing step, and the rinsing is completed quickly. .

  Patent Document 4 discloses a liquid cleaning containing polyoxyalkylene alkyl ether sulfate, alkylbenzene sulfonate, fatty acid and / or salt thereof under specific conditions, and a nonionic surfactant content of 2 mass% or less. It is disclosed that the agent composition has excellent detergency in washing clothes and the like, and is excellent in both foaming and rinsing properties.

Such as adding an agent to form a salt in the composition.

  The liquid detergent composition of the present invention is suitable for washing at home and also for hand washing, and is suitably used for hand washing of textile products such as clothing, cloth, bedding, towels and the like.

  The present invention relates to a hand-washing laundry method for hand-washing an object to be cleaned that has been brought into contact with cleaning water containing the liquid detergent composition of the present invention. Examples of the hand-washing washing method using the liquid detergent composition of the present invention include a method of hand washing by bringing a washing water containing the liquid detergent composition of the present invention into contact with an object to be washed such as a fabric. The washing water can be contacted by dipping, coating, spraying, or the like. When the contact time is long, the cleaning effect is high, and when the contact time is 5 minutes or more and 15 minutes or less, a better effect is obtained. In addition, the liquid detergent composition of the present invention is directly applied to the soiled part and left for 5 to 15 minutes, and then washed with water containing the liquid detergent composition of the present invention for hand washing. Then, a higher effect can be obtained.

  As the washing water in the hand-washing washing method, the composition of the present invention or a water dilution of the composition (for example, an aqueous solution) is used. The water used here is generally tap water, and tap water in each country including Japan usually has alkalinity (buffer capacity). However, even when the liquid detergent composition of the present invention is diluted with tap water having alkalinity, the pH is 8 or more, preferably 8.5 or more, 10.5 or less exceeding the buffer capacity of the tap water. Therefore, excellent cleaning performance as designed is achieved. The mass of the washing water with respect to the mass of the object to be cleaned such as a fabric is preferably 2 times or more, further 3 times or more, further 5 times or more, 100 times or less, further 50 times or less, and further 25 times or less. When the object to be cleaned such as the fabric brought into contact with the cleaning water according to the present invention is sufficiently rubbed by hand, not only a high detergency is obtained but also abundant foaming is visually preferred.

  The hand-washing washing method of the present invention preferably includes a step of rinsing the article to be washed after hand washing with water. After hand washing such as rubbing, the object to be washed such as cloth is taken out from the washing water, squeezed to drain the water, or drained with a dehydrator, and dipped again in fresh water (hereinafter referred to as rinsing water). The rinsing water may be either water stored in a basin or running water. The mass of the rinsing water with respect to the fabric is preferably 2 times or more, further 5 times or more, further 10 times or more, preferably 1,000 times or less, further 500 times or less, based on the total amount of rinsing water used for rinsing. Furthermore, it is 100 times or less. Since the surfactant remaining in the fabric at the stage of immersing the rinse water is redissolved in the rinse water, foaming is observed. When this operation is repeated several times, the foaming disappears and the rinsing is completed.

  In general washing by hand, for example, when a normal cleaning agent is used, foam generated at the time of washing does not disappear, so it is generally required 5 times or more, but in the present invention, it is rinsed 3 times or less. The rinsing can be completed with very little rinsing water, eliminating the need for wasteful use of water.

  In the liquid cleaning composition of the present invention, at least one of the hardness of the water used for the preparation of the cleaning water and the hardness of the rinsing water is 1 ° DH or higher, more preferably 2 ° DH or higher, from the viewpoint of cleaning power and rinsing properties. Further, it may be 3 ° DH or more, further 4 ° DH or more, further 6 ° DH or more, further 8 ° DH or more, further 10 ° DH or less, 50 ° DH or less, further 40 ° DH or less, and further 30 It is preferably at least DH and more preferably at most 20 DH.
