[Name 1 Ayito ffl

[Name of investigation] Liquid detergent composition for clothing

【Technical field】

[0001]

The present invention relates to a liquid detergent composition used for washing clothes.

[Background]

[0002]

In recent years, an increasing number of households dries laundry indoors due to changes in daily rhythms, hay fever measures, crime prevention measures, etc., but if they are dried in a humid room after washing, Since bacteria tend to grow and become odorous against dirt such as sebum, its deodorization and deodorization are strongly desired. Also, in daily life, the number of people who are concerned about body odor is increasing, and there is a high demand for deodorizing and deodorizing products against body odor. Therefore, in order to meet these demands, antibacterial compounds are added to liquid detergents for clothing to suppress the generation of odors in indoor drying or discomfort by disassembling dirt when wearing clothing. Many attempts have been made to suppress the generation of odors.

[0003]

For example, (A) a specific anionic surfactant 0.2 to 3.0% by weight, (B) a specific cation having a stoichiometric ratio A: B in the range of 0.05 to 0.3: 1 Surfactant 3. 8-7 wt%, (C) Specific nonionic surfactant 7-30 wt%, (D) Alkali metal benzoate 1-6 wt%, (E) Consists of water, required A liquid laundry detergent containing an anionic brightener, a fragrance, a dye, a water repellent, etc. is disclosed (see Patent Document 1).

0004

In addition, (A) Specific water-soluble antibacterial compound 0.1 to 0% by weight, (B) 1 _heptano monole, σ-methylionone, n-decylaldehyde, n-undecyl aldehyde, etc. more compounds from 0.001 to 0.5 wt ^_0/0, (C) ^α- Ionon, § Se Chino receptacle drain, one or more compounds selected from § Se chill eugenol etc. from 0.001 to 0.5 wt%, By using together a compound containing 10-50% by weight of a nonionic surfactant and / or anionic surfactant and showing the antibacterial effect of component Β and a compound having a relatively high boiling point of component C, A liquid detergent composition that leaves a fragrance having an antibacterial effect is disclosed (see Patent Document 2).

[0005]

However, in the first place, if the unpleasant sweaty odor and sock odor attached to clothing are not removed sufficiently during washing, the raw dry odor generated when drying indoors cannot be suppressed. And even worse, there is the problem that intense odors such as socks can be transferred to other clothing. Also, due to the recent spread of dryers and washing machines with a drying function, if the clothes after washing are not dried indoors, they are dried immediately after washing in a dryer or washing machine with a drying function, so that a dry odor does not occur. However, there is a problem that the odor attached to the clothes remains after drying if it cannot be removed during washing.

.

Therefore, as a detergent composition that removes such unpleasant odor as completely as possible, for example, secondary alcohol ethylene oxide adduct, sulfate alcohol salt of secondary alcohol ethylene oxide adduct and amphoteric A detergent composition that removes dirt and phrase V peculiar to socks containing a surfactant as an active ingredient has been disclosed (see Patent Document 3). However, this product does not take into account the removal of the raw odor during indoor drying.

[0007]

Further, (a) specific and antimicrobial compounds from 0.01 to 10 wt%, has a Aruki Honoré or alkenyl (b) C "~C _22, with an HLB of 0.5 to 5, molecular weight 450: Nonionic or cationic lipophilic compound of I 500 0.:! ~ 20% by weight, and (c) Nonionic or anionic surfactant other than the above antibacterial compounds with HLB exceeding 5. : -30% by weight and water are blended, and a β product deodorant treatment agent that can be easily subjected to a deodorization treatment on a textile product using a washing machine is disclosed (see Patent Document 4). This is different from the cleaning process using a cleaning agent, and has the annoyance that a deodorizing agent must be added in a separate process.

[0008] On the other hand, for the purpose of disinfecting bacteria attached to clothing during washing and for the purpose of antibacterial to suppress the growth of bacteria transferred from the air to clothing when drying the clothing, A method of blending an activator has also been proposed, but due to the electrostatic interaction of the cationic surfactant, stains in the washing solution and dyes derived from colored clothing reattach to the clothing, resulting in recontamination and transfer. There is a problem of inviting.

[0009]

As a method for solving such re-contamination and transfer problems, for example, a nonionic surfactant, a polymer component made of water-soluble polyvinylpyrrolidone, a component contained in a builder and a normal detergent are included. In addition, a detergent containing a dye or whitening agent, which contains a water-soluble cation compound and does not contain any strong electrolytes, in a detergent that does not contain any cation-active compounds (Patent Document 5) And (A) 0.1 to 20% by weight of a specific cationic antibacterial agent and (B) 0.1 to 20% by weight of a polycarboxylate polymer having a weight average molecular weight of 1,000 to 1,000,000. A liquid detergent composition having a pH (25 ° C) of 7.5 to 11 having an anti-recontamination effect, an antibacterial effect, and product storage stability has been disclosed for use in clothing (see Patent Document 6). See) However, these products are unsatisfactory in terms of preventing migration of clothes and deodorizing properties, and those with better performance are strongly desired.

In addition, the present inventors have found that a liquid cleaning composition can be obtained that can suppress the raw dry odor generated when drying indoors and that causes little recontamination to clothing, and has reached the present invention.

【The invention's effect】

[0 0 1 6]

The liquid detergent composition for clothing of the present invention combines a specific nonionic surfactant, a cationic surfactant, and a water-soluble polymer in specific ratios, and also adds an alcoholic agent. The stock solution of the composition and the pH at the time of dilution are maintained in a predetermined range. According to this liquid cleaning composition for clothing, not only can the odor attached to the clothing be effectively removed, but also the freshly dried odor generated during indoor drying can be suppressed. In addition, it has excellent anti-contamination performance for clothing.

BEST MODE FOR CARRYING OUT THE INVENTION

[0 0 1 7]

Next, the best opening state for carrying out the present invention will be described in detail.

[0 0 1 8]

The alkaline agent (A) used in the liquid detergent composition for clothing of the present invention (hereinafter abbreviated as “the present composition”) is effective in removing odors derived from the body attached to the surface to be cleaned of clothes. In addition to contributing, it improves the disinfection action against bacteria attached to the surface to be cleaned and contributes to the cleaning effect of dirt on clothing.

[0 0 1 9]

As the component (A), various conventionally known alkaline agents can be used. Among them, ethanolamines such as monoethanolamine, diethanolamine, and triethanolamine are particularly effective. Are preferably used. These may be used alone or in combination of two or more.

[0 0 2 0]

The blending amount of the component (A) is a force that is appropriately set in order to adjust the final pH of the composition. In particular, in the present invention, 1 to 30% by mass with respect to the entire composition. (Hereinafter abbreviated as “%”). In other words, when the blending amount is less than 1%, the deodorization and sterilization effects are improved and the cleaning effect is poor, and when it exceeds 30%, the deodorization and sterilization effects are improved and the cleaning effect is saturated. Because it is economically disadvantageous. In particular, the range of 1 to 15% is particularly suitable from the viewpoint of deodorization, improvement of sterilization effect, cleaning effect and economical efficiency.

[0 0 2 1]

The nonionic surfactant of component (B) used in the present composition mainly contributes to the cleaning effect, and a wide range of nonionic surfactants can be used.

That is, when the blending amount is less than 10%, the cleaning effect is poor, and when it exceeds 30%, the cleaning effect becomes saturated, which may be disadvantageous economically. In addition, there is a risk that the sterilization effect and antibacterial effect may be reduced due to the balance with the cationic surfactant. From this point of view, the blending amount of the nonionic surfactant as the component (ii) is particularly preferably set in the range of 12 to 20%.

[0024]
