Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rinsing aid composition for imparting functionality, which is used in a rinsing process during washing. More specifically, the present invention is a general cleaning of clothes and the like, sheets, wrapping cloth, pillow case, towel, table cloth, prevention of yellowing due to residual alkali resulting from poor rinsing in cleaning linen supplies such as diapers, The present invention relates to a rinsing aid composition that provides deodorization of residual odor due to poor cleaning, antibacterial properties for keeping cleaned products clean, and improvement of whiteness of cleaned products.

[0002]

2. Description of the Related Art In the washing of clothes and linen supplies, washing is carried out under an alkaline pH, and in the case of poor rinsing, yellowing frequently occurs due to residual alkali. In order to prevent this yellowing, conventionally, a neutralizing agent such as acetic acid and sodium silicofluoride has been used, but when the neutralizing agent is acetic acid, the peculiar acid odor is a problem. Has problems with wastewater regulations, such as the amount of fluorine in wastewater that may conflict with the Sewerage Law. Inorganic acids may be used as other neutralizing agents, but they are not suitable as neutralizing agents because the fabric becomes brittle.

Further, a deodorant is separately used to remove the residual odor caused by poor washing. Further, as an infectious medium for nosocomial infection and the like, there are sheets, clothes and the like, but an antibacterial agent is separately used for the purpose of preventing the infection, and thus agents for different purposes are separately injected.

[0004]

SUMMARY OF THE INVENTION The present invention addresses the acid odor and drainage regulations found in conventional laundry neutralizers, has no adverse effects on the human body, and produces yellow due to residual alkali in laundry. Prevents deterioration of quality due to colored metals such as iron and manganese in rinsing water, and also has other complex functions such as deodorant action, antibacterial action and whiteness improvement, simplifying the washing process and improving washing efficiency It is an object of the present invention to provide a laundry rinsing aid composition that can be used.

[0005]

As a result of intensive studies to solve the above problems, the present inventors have combined an organic acid, a deodorant, an antibacterial agent, and a water-soluble fluorescent dye in a specific amount to obtain a system pH. It was discovered that the above object can be achieved by setting the ratio to 3 or less, and the present invention has been completed.

That is, the present invention is 10 to 80% by weight,
Deodorant consisting of preferably 20-60% by weight of organic acid, 3-40% by weight, preferably 5-20% by weight of natural plant extract and / or cyclic polysaccharide type compound, 1-40% by weight, preferably 2-20% by weight of antibacterial agent and 0-2
The present invention provides a rinsing aid composition for laundry which comprises an aqueous solution containing a water-soluble fluorescent dye in an amount of 0.5% by weight, preferably 0.5 to 1% by weight, and has a pH of 3 or less.

As the organic acid used in the present invention, an organic acid having no or little odor is preferably used. Examples include oxalic acid, glycolic acid, tartaric acid, citric acid, isocitric acid, malic acid, malonic acid, fumaric acid, succinic acid, maleic acid, ascorbic acid, sulfamic acid, etc. From the viewpoint of preventing oxidization, citric acid, malic acid, tartaric acid and glycolic acid are particularly preferable. These organic acids are
Each may be used alone or as a mixture of two or more. If the amount of the organic acid is less than 10%, it is insufficient to neutralize the residual alkali, and if it exceeds 80%, the pH of the rinsing bath is too low, and a rinsing aid composition containing other constituents effectively is obtained. It becomes difficult to obtain.

The deodorant used in the present invention is selected from natural plant extract components and cyclic polysaccharide type compounds. Examples of such deodorants include fresh shiramatsu (manufactured by Shiraimatsu Shinyaku Co., Ltd.) which is a natural extract component, OCLEAN EX (manufactured by Taiyo Kyoku Co., Ltd.), and cyclodextrin which is a cyclic polysaccharide type compound. Is preferably used. Each of these deodorants may be used alone, or 2
It may be used as a mixture of two or more species. If the amount of this deodorant is less than 3%, a sufficient deodorizing effect cannot be obtained, and if it is used in excess of 40%, there is a problem in terms of economical efficiency with respect to the deodorizing effect, and other components are effective. It becomes difficult to obtain a rinsing aid composition blended with.

A typical example of the antibacterial agent used in the present invention is a quaternary ammonium salt compound. For example, Nikkanon BZ (Nika Kagaku Co., Ltd.)
Manufactured by Nikkanon RB (produced by Nika Kagaku Co., Ltd.) are preferably used. These antibacterial agents can also be used alone or as a mixture of two or more kinds. If the amount of this antibacterial agent is less than 1%, it is insufficient to obtain an effective antibacterial action, and if it is used in excess of 40%, there is a problem in terms of economic efficiency with respect to the antibacterial effect. It becomes difficult to obtain an effectively blended rinsing aid composition.

Examples of the water-soluble fluorescent dye used in the present invention include Chinopearl CBS-X (manufactured by Ciba Geigy), Kayahole FBconc, Kayahole Bc.
onc (manufactured by Nippon Kayaku Co., Ltd.) Illuminal SP Conc,
Illuminal BSN Conc (Showa Kako Co., Ltd.) is preferred. These water-soluble fluorescent dyes can also be used alone or as a mixture of two or more kinds. When the water-soluble fluorescent dye is used in an amount exceeding 2%, the concentration of the fluorescent dye becomes high, and there is a problem that a quenching phenomenon occurs.

The rinse aid of the present invention comprising an aqueous solution containing the above components has a pH of 3 or less. When the pH exceeds 3,
The amount of the auxiliary agent of the present invention necessary for neutralizing the residual alkali during rinsing becomes extremely large, which is uneconomical and makes it difficult to balance the effective mixing ratio with other mixing components. The rinsing aid of the present invention, if desired, a fragrance, a dye,
You may further mix other components, such as a chelate dispersant and a preservative.

Although the rinsing aid of the present invention depends on the washing conditions, it is generally effective when added to the rinsing tank in an amount of 2 to 4 ml per kg of the article to be washed.

[0013]

The present invention will be further described with reference to examples, but the present invention is not limited to these examples. A rinsing aid having the composition (% by weight) shown in Table 1 below was prepared, washed and rinsed under the following conditions, and the pH lowering ability,
The deodorant property, antibacterial property and fluorescent whiteness were evaluated.

Condition Washing machine: Automatic washing and dehydrating machine SCW-5101 (manufactured by Sanyo Electric Co., Ltd.) Load amount 10 kg Detergent used: Siroc KR-401 (Nikaka Co., Ltd.)
80 g Neolate R-127 (manufactured by Nika Kagaku Co., Ltd.) 80 g Washing conditions: 60 ° C. × 10 minutes (medium water level) Rinsing conditions: 5 minutes × 3 times Add a rinsing aid to the third rinse

Evaluation method pH lowering ability: pH of waste water is measured during the third dehydration of rinsing Deodorizing ability: Smell the odor before and after drying of the object to be washed after treatment and judge according to the following criteria ◎ Odor No odor ○ Almost no odor △ Slight odor × Smell Antibacterial property: Place the washed sample as a test sample on the agar medium inoculated with Staphylococcus aureus at 37 ° C for 24 hours. The bacteria are cultured for a period of time, and the antibacterial effect is judged by the presence or absence of growth of Staphylococcus aureus around the sample.

◎ Large halo (with antibacterial effect) ○ Halo (with antibacterial effect) △ Slight halo (with antibacterial effect) × No halo (without antibacterial effect) Fluorescent whiteness : Judge by measuring the value of Stensby FW. I with a colorimeter (Macbeth color eye).

The results obtained are also shown in Table 1.
