Description

Deodorant composition

Technical Field

The present invention relates to an deodorant composition, a method of deodorizing, and a deodorizing wipe material.

Background

Since the inside of shoes when worn has an environment in which bacteria grow perfectly due to sweat and body temperature, valeric acid and isovaleric acid, which are metabolites of bacteria, are produced, which causes odor. Such odor is generally deodorized by spraying an odor eliminating agent, but this is not a fundamental measure. Therefore, there is a strong demand for a technique for deodorizing by suppressing the growth of bacteria and fundamentally eliminating the cause of odor.

Jp 2018 a 104428 discloses a technique of a bactericide composition containing a quaternary ammonium salt against skin-resident bacteria and various bacteria existing in the environment, and describes the use of a nonionic surfactant in combination.

Jp 2003-3371 a discloses a technology of a fabric deodorant containing a cationic surfactant and a nonionic surfactant.

Jp 2018-90564 a and jp 2019-112342 a disclose a technique of a cleaning sheet having excellent mold resistance, and a technique of using a quaternary ammonium salt surfactant and a nonionic surfactant in combination.

Disclosure of Invention

However, if these techniques are applied to an odor control agent for an article containing a material having high water repellency and water repellency, such as shoes, there is a problem that a sufficient odor control effect cannot be obtained. Further, it is also considered that the concentration of the cationic surfactant is increased to enhance the deodorizing effect, but when skin irritation or the like is considered, a technique is required which is excellent in the deodorizing effect even if the concentration of the cationic surfactant is low.

The invention provides an odor control agent composition, an odor control method, and an odor control wiping material, which have excellent odor control effects even when the concentration of a cationic surfactant is low.

The present invention relates to an deodorant composition containing (a) a cationic surfactant [ hereinafter referred to as component (a) ], (b) a nonionic surfactant having an HLB of less than 12.5 as determined by the griffin method [ hereinafter referred to as component (b) ], and water, wherein the mass ratio (b)/(a) of the content of component (b) to the content of component (a) is 0.4 to 5.0.

The present invention also relates to a method for deodorizing by bringing the deodorant composition into contact with an object.

The present invention also relates to a deodorizing wipe material comprising the deodorizing agent composition and a nonwoven fabric.

The present invention also relates to a microbicide composition containing component (a), component (b), and water, wherein the mass ratio (b)/(a) of the content of component (b) to the content of component (a) is 0.4 to 5.0.

The present invention also relates to a fungicide composition containing the component (a), the component (b), and water, wherein the mass ratio (b)/(a) of the content of the component (b) to the content of the component (a) is 0.4 to 5.0.

According to the present invention, there are provided an odor control agent composition, an odor control method, and an odor control wiping material which are excellent in odor control effect even when the concentration of a cationic surfactant is low.

[ composition, etc. ]

Shoe insoles and the like use water-repellent materials such as urethane, and have properties such as sweat absorption. Therefore, odor derived from bacteria is also generated from the inside, and the deodorizing effect does not continue for a general deodorizing agent. Therefore, a method of preventing generation of malodor using a bactericide is desired.

Cationic surfactants are powerful bactericides, but are not easily adhered uniformly to water-repellent materials, and particularly to hydrophobic surfaces having a surface free energy of 40Nm/m or less, there are the following problems: the effect of the bactericide does not spread over the entire surface of the object, and as a result, satisfactory deodorizing effect cannot be obtained.

In order to uniformly adhere a cationic surfactant, a technique of using a surfactant other than the component (b) of the present invention in combination is considered, but not only deterioration of touch such as foaming and stickiness occurs in a portion in contact with the skin, but also the bactericidal effect of the cationic surfactant is weakened.

In the present invention, by using a nonionic surfactant having a low HLB in combination, not only can the cationic surfactant be spread uniformly, but also the bactericidal effect can be improved, and therefore, even if a cationic surfactant is used at a low concentration, a high deodorizing effect can be obtained. Although the mechanism of action is not clear, it is presumed that the mixed micelle of the nonionic surfactant having a low HLB and the cationic surfactant improves wettability with respect to a hydrophobic surface having a surface free energy of 40Nm/m or less, and can be uniformly applied, and that the nonionic surfactant having a low HLB acts on the surface of bacteria to enhance the bactericidal effect of the cationic surfactant.

The deodorant composition of the present invention contains the component (a) in an amount of preferably 0.05% by mass or more, more preferably 0.1% by mass or more, and still more preferably 0.2% by mass or more, and preferably 5% by mass or less, more preferably 2% by mass or less, still more preferably 1% by mass or less, and still more preferably 0.5% by mass or less, from the viewpoint of bactericidal properties and deodorant properties. In the present invention, the mass of the component (a) is a value obtained by converting an anion as a counter ion into a chloride ion.

The deodorant composition of the present invention contains the component (b) in an amount of preferably 0.1% by mass or more, more preferably 0.2% by mass or more, further preferably 0.3% by mass or more, and preferably 5% by mass or less, more preferably 2% by mass or less, further preferably 1% by mass or less, and further preferably 0.8% by mass or less, from the viewpoints of wettability to an object, cleaning properties, and bactericidal properties and deodorant properties due to coexistence with a cationic surfactant.

In the deodorant composition of the present invention, the mass ratio (b)/(a) of the content of the component (b) to the content of the component (a) is 0.4 or more, preferably 0.8 or more, more preferably 1 or more, further preferably 1.5 or more, still more preferably 2 or more, and 5 or less, preferably 4 or less, more preferably 3.5 or less, and further preferably 3 or less, from the viewpoint of synergistic effects of bactericidal properties and deodorant properties.

In the deodorant composition of the present invention, the total mass of the content of the component (a) and the content of the component (b) is preferably 0.1% by mass or more, more preferably 0.2% by mass or more, further preferably 0.3% by mass or more, further preferably 0.4% by mass or more, further preferably 0.5% by mass or more, and preferably 5% by mass or less, more preferably 3% by mass or less, further preferably 2% by mass or less, further preferably 1.6% by mass or less, from the viewpoints of bactericidal properties and deodorant properties.

The deodorant composition of the present invention may contain a nonionic surfactant other than the component (b) [ hereinafter referred to as component (b') ], but the effect of the present invention may be impaired, and thus attention is required. When the HLB of component (b ') is determined by griffin's method, the deodorant composition of the present invention may contain component (b ') within a range in which the HLB of the mixed surfactant of component (b) and component (b') satisfies a range of preferably 17 or less, more preferably 15 or less, and still more preferably less than 12.5 and 8 or more from the viewpoints of bactericidal property and deodorant property. The HLB of the mixed surfactant is assumed to have an additive property.

When the deodorant composition of the present invention contains component (b ') that cannot be obtained by griffin's method, the HLB of the mixed surfactant of component (b) and component (b ') can be calculated from the experimentally obtained HLB of component (b') as described below.

The surfactant having a known HLB determined by the griffin method can be combined with the component (b'), the fat or oil having a known HLB is emulsified with water, and the optimum mixing ratio for the emulsified state is selected and calculated from the formula (I).

{(W_u×HLB_u)+(W_a×HLB_a)}/(W_u+W_a)＝HLB₀(I)

[ Here, W_u: mass fraction of component (b'), W_a: mass fraction of surfactant with known HLB, HLB_u: HLB of surfactant with unknown HLB, HLB_a: HLB known HLB of surfactant, HLB₀: HLB is known as the HLB of the fat. Angle (c)

The deodorant composition of the present invention may contain a surfactant [ hereinafter, referred to as component (e) ] other than the components (a), (b) and (b'), but the effect of the present invention may be impaired, and thus attention is required. The component (e) includes (e1) anionic surfactants [ hereinafter referred to as (e1) component ], (e2) amphoteric surfactants [ hereinafter referred to as (e2) component ], but since the deodorizing effect may be reduced particularly by the component (e1), the content of the component (e1) in the deodorant composition of the present invention is 1 mass% or less, preferably 0.5 mass% or less, more preferably 0.1 mass% or less. In the case where the component (e1) is contained in the deodorant composition of the present invention, the mass ratio (a)/(e1) of the content of the component (a) to the content of the component (e1) is preferably 5 or more, preferably 10 or more, and more preferably 100 or more, from the viewpoint of obtaining a high deodorant effect.

In view of the tactile sensation of the treated surface, attention is required in the case of using the (e2) component. (e2) Since the component (e2) is a surfactant having foaming properties and exhibits an undesirable texture such as stickiness on the surface after treatment, the content of the component (e2) is 1 mass% or less, preferably 0.5 mass% or less, and more preferably 0.1 mass% or less in the deodorant composition of the present invention when used.

In the deodorant composition of the present invention, the total content of the component (a) and the component (b) in the total surfactant is preferably 50% by mass or more, more preferably 60% by mass or more, further preferably 70% by mass or more, further preferably 80% by mass or more, further preferably 90% by mass or more, and may be 100% by mass or less, and may be 100% by mass.

The present invention relates to a method for deodorizing by bringing the deodorant composition of the present invention into contact with an object. The deodorizing method of the present invention can be preferably used for deodorizing malodor originating from bacteria.

The deodorizing method of the present invention can be suitably applied to the matters described in the deodorizing agent composition of the present invention.

The surface free energy of the present invention was calculated by using the following formula (II) of OWRK (Owens-Wendt-Rabel-Kaelble) and substituting the contact angles (and the apparent contact angles in the case of using rough surfaces) of liquid paraffin (and optical grade, fuji film and optical pure chemical) and ultrapure water (for LC/MS, fuji film and optical pure chemical) which are known as surface tensions for the respective surfaces.

(

σ_sSurface free energy of solid, σ _lSurface tension of the liquid, θ: is connected withAn antenna, d a dispersing component, and P a polar component. )

It is considered that such a hydrophobic surface cannot uniformly adsorb a cationic surfactant. In addition, a method of improving the wettability of a hydrophobic surface is considered for uniformly adsorbing a cationic surfactant, and a method of using a surfactant is generally carried out, but the wettability improving effect is poor for surfactants other than the component (b) of the present invention. Although the mechanism of action is not clear, it is presumed that in the present invention, a mixed micelle is formed between the component (a) and the component (b), and as a result, a small amount of the cationic surfactant can be uniformly adsorbed on the hydrophobic surface.

In the present invention, from the viewpoint of cleaning property, feeling of effect and quick-drying property, it is preferable to use 100cm of the hydrophobic surface of the object²The deodorant composition of the present invention is brought into contact with an object at a ratio of preferably 20mg or more, more preferably 30mg or more, further preferably 40mg or more, and preferably 400mg or less, more preferably 200mg or less, further preferably 100mg or less. In addition, from the viewpoint of unpleasant feeling such as stickiness and skin irritation, it is preferable that the total mass of the component (a) and the component (b) is 100cm with respect to the hydrophobic surface of the object ²The deodorant composition of the present invention is brought into contact with an object in such a manner that the amount of the deodorant composition is 20 μ g or more, preferably 40 μ g or more, more preferably 60 μ g or more, further preferably 80 μ g or more, particularly preferably 100 μ g or more, and 20mg or less, preferably 10mg or less, more preferably 5mg or less.

Specifically, the object to be brought into contact with the deodorant composition of the present invention can be applied to plastic materials such as urethane resins, silicone resins, polyester resins, polyethylene resins, polypropylene resins, and polystyrene resins, foamed articles (foams) obtained by using the plastic materials, and materials formed into porous shapes. Specifically, the present invention is effective for objects having problems with sweat odor, such as shoe insoles, leather, mattresses, home appliances such as sofas, hats, and helmets.
