Description

Technical Field

[0001] The present invention relates to a smoothness enhancer and a detergent composition.

Background Art

[0002] Conventionally, detergent compositions such as hand soap and body soap have been required to impart a smooth feeling to the skin after towel drying. As a detergent composition capable of imparting a smooth feeling to the skin after towel drying, for example, a detergent composition containing a dimethyldiallylammonium chloride polymer, a sugar alcohol, silica, etc. has been proposed (see, for example, Patent Documents 1 to 3).

[0003] In addition, since the detergent composition is used for the purpose of keeping the cleaning site clean, it is also required that a feeling of cleanliness can be felt by using the detergent composition. Among the various characteristics of the detergent composition, the fragrance imparted to the detergent composition contributes to producing a feeling of cleanliness, and the goodness of a highly preferred fragrance is also an important quality of the detergent composition. Therefore, detergent compositions containing various fragrance compositions have been proposed (see, for example, Patent Documents 4 to 6).

[0004] Therefore, there is a strong demand for a smoothness enhancer that can make the smooth feeling of the skin after towel drying felt more strongly and can impart a fragrance that gives a feeling of cleanliness in a detergent composition capable of imparting a smooth feeling to the skin after towel drying, and a detergent composition containing the smoothness enhancer.

Advantages of the Invention

[0009] According to the present invention, it is possible to solve the above-mentioned conventional problems, achieve the above object, and provide a detergent composition that can impart a smooth feeling to the skin after towel drying. In the detergent composition, it is possible to more strongly feel the smooth feeling of the skin after towel drying, and it is possible to provide a smoothness enhancer that can impart a fragrance that gives a feeling of cleanliness when rinsing the detergent composition, and a detergent composition containing the smoothness enhancer.

Mode for Carrying Out the Invention

[0010] (Smoothness Enhancer) The smoothness enhancer of the present invention contains (a) at least one selected from the group consisting of γ-terpinene, α-farnesene, and p-cymene, (b) at least one selected from the group consisting of allyl caproate, ethyl enanthate, allyl enanthate, and ethyl caprate, and (c) at least one selected from the group consisting of γ-decalactone, δ-decalactone, γ-undecalactone, and δ-undecalactone, and further contains other components as necessary.

[0011] The five senses are not independent but interact with each other, and it is known that the image felt from the fragrance (i.e., the image based on olfactory information) also affects tactile information (see "Product Development Appealing to Human Sensibility and Its Evaluation (No. 1952)", Chapter 7, Section 6, Case of Evaluating the Value of the Fragrance of Fabric Softeners / Technical Information Association). The present inventors have conducted intensive studies and found that the smoothness enhancer containing the components (a), (b), and (c) in a specific content ratio can not only impart a fragrance that gives a feeling of cleanliness, but also make the user feel a sensory smooth feeling of the skin from the fragrance. It has not been conventionally known that a fragrance or fragrance composition used in a detergent composition has not only a preference as a fragrance but also a functional value that backs up the function of the detergent composition and can make the user feel a sensory smooth feeling of the skin, which is a new finding by the present inventors.

[0012] <At least one selected from the group consisting of (a) γ-terpinene, α-farnesene, and p-cymene> At least one selected from the group consisting of γ-terpinene (also referred to as "γ-terpinen"), α-farnesene, and p-cymene as the component (a) is mainly contained in order to make the feeling of smoothness on the skin after towel drying stronger when formulated in the detergent composition. Among these, the component (a) is preferably p-cymene in that it can make the feeling of smoothness on the skin after towel drying stronger when formulated in the detergent composition.

[0013] As the component (a), those synthesized as appropriate may be used, or commercially available products may be used. Examples of commercially available products of the component (a) include γ-Terpinene (γ-terpinene), (-)-α-Phellandrene (α-farnesene), p-Cymene (p-cymene) (manufactured by Tokyo Chemical Industry Co., Ltd., etc.). These may be used alone or in combination of two or more.

[0014] The content of the component (a) in the smoothness enhancer is not particularly limited as long as the mass ratio [((a)+(b)) / (c)] described later is 1 to 10, and it can be appropriately selected according to the purpose.

[0015] <At least one selected from the group consisting of (b) allyl caproate, ethyl enanthate, allyl enanthate, and ethyl caprate> At least one selected from the group consisting of allyl caproate, ethyl enanthate, allyl enanthate, and ethyl caprate as the component (b) is mainly contained in order to make the feeling of smoothness on the skin after towel drying stronger when formulated in the detergent composition. Among these, the component (b) is preferably allyl enanthate in that it can make the feeling of smoothness on the skin after towel drying stronger when formulated in the detergent composition.

[0016] As the component (b), those synthesized as appropriate may be used, or commercially available products may be used. Examples of commercially available products of the component (b) include ALLYL CAPROATE, ETHYL HEPTOATE, ALLYL HEPTOATE, ETHYL CAPRYLATE (all manufactured by Shimryz Co., Ltd.), etc. These may be used alone or in combination of two or more.

[0017] The content of the component (b) in the feeling enhancer is not particularly limited as long as the mass ratio [((a)+(b)) / (c)] described later is 1 to 10, and it can be appropriately selected according to the purpose.

[0018] <At least one selected from the group consisting of (c) γ-decalactone, δ-decalactone, γ-undecalactone, and δ-undecalactone> At least one selected from the group consisting of γ-decalactone, δ-decalactone, γ-undecalactone, and δ-undecalactone as the component (c) is mainly contained in order to make the feeling of smoothness on the skin after towel drying stronger when blended in the detergent composition. Among these, the component (c) is preferably γ-undecalactone in that it can make the feeling of smoothness on the skin after towel drying stronger when blended in the detergent composition.

[0019] As the component (c), those synthesized as appropriate may be used, or commercially available products may be used. Examples of commercially available products of the component (c) include, for example, C-10 GAMMA DECALACTONE (γ-decalactone), C-10 DELTA DECALACTONE (δ-decalactone), C-11 GAMMA UNDECALACTONE (γ-undecalactone), C-11 DELTA UNDECALACTONE (δ-undecalactone) (manufactured by Soda Aroma Co., Ltd., etc.). These may be used alone or in combination of two or more.

[0020] The content of the component (c) in the crispy feeling enhancer is not particularly limited as long as the mass ratio [((a)+(b)) / (c)] described later is 1 to 10, and it can be appropriately selected according to the purpose.

[0021] <Mass ratio [((a)+(b)) / (c)]> The mass ratio [((a)+(b)) / (c)] of the total content of the component (a) and the component (b) to the content of the component (c) is 1 to 10, preferably 2 to 5, from the viewpoints of making the crispy feeling on the towel-dried skin felt stronger and imparting a fragrance that gives a clean feeling when the detergent composition is rinsed. When the mass ratio [((a)+(b)) / (c)] is less than 1, a fragrance that gives a clean feeling cannot be imparted when blended in the detergent composition, and when it exceeds 10, the crispy feeling on the towel-dried skin cannot be felt stronger.

[0022] In this specification, the "fragrance that gives a clean feeling" means a fragrance that can feel citrus fragrance elements. Citrus-based fragrances are refreshing and are preferred by consumers as fragrances that give a clean feeling.

[0023] <Other components> In the crispy feeling enhancer, in addition to the components (a), (b), and (c), other components can be further blended as necessary within a range that does not impair the effects of the present invention.

[0024] The other components are not particularly limited and can be appropriately selected according to the purpose. For example, fragrance components, fragrance compositions, etc. other than the component (a), the component (b), and the component (c) can be mentioned. The fragrance components other than the component (a), the component (b), and the component (c) are not particularly limited and can be appropriately selected from known fragrance components. For example, α-terpineol, citronellol, α-damascenone, geranyl acetate, etc. can be mentioned. These may be used alone or in combination of two or more.

[0025] As the other components, those synthesized as appropriate may be used, or commercially available products may be used.

For example, a stirring device equipped with stirring blades having shear force and capable of mixing the whole can be mentioned. The stirring blades are not particularly limited and can be appropriately selected according to the purpose. For example, propellers, turbines, dispersers, etc. can be mentioned.

[0027] - Use - In a detergent composition in which the crispy feeling enhancer can impart a crispy feeling to the skin after towel drying, it can make the user feel a stronger crispy feeling on the skin after towel drying and can impart a fragrance that gives a feeling of cleanliness when rinsing the detergent composition. Therefore, it can be suitably used in known detergent compositions and can be particularly suitably used in the detergent composition of the present invention described later.

[0028] (Detergent composition) The detergent composition of the present invention contains the crispy feeling enhancer of the present invention and at least one selected from the group consisting of (d) dimethicone and dimethiconol, and further contains other components as necessary.

[0029] The detergent composition can make the user feel a sensory crispy feeling of the skin not only due to the crispy feeling of the skin after towel drying based on the composition attributed to the component (d), but also due to the crispy feeling enhancer. Therefore, the crispy feeling of the skin after towel drying is more excellent. Therefore, the detergent composition is completely different from conventional products that impart a crispy feeling depending on the composition of the detergent composition.

[0030] <Crispy feeling enhancer> The crispy feeling enhancer contained in the detergent composition is the crispy feeling enhancer of the present invention as described above.

[0031] The content of the crispy feeling enhancer in the detergent composition is not particularly limited and can be appropriately selected according to the purpose.

[0032] -(Component (a))- The content of the component (a) in the detergent composition is not particularly limited and can be appropriately selected according to the purpose. However, in terms of making the feeling of smoothness on the skin after towel-drying stronger, 0.001% by mass to 0.01% by mass is preferable, and 0.003% by mass to 0.01% by mass is more preferable. When the content of the component (a) in the detergent composition is 0.001% by mass or more and 0.01% by mass or less, the feeling of smoothness on the skin after towel-drying can be made stronger.

[0033] -(Component (b))- The content of the component (b) in the detergent composition is not particularly limited and can be appropriately selected according to the purpose. However, in terms of making the feeling of smoothness on the skin after towel-drying stronger, 0.001% by mass to 0.01% by mass is preferable, and 0.001% by mass to 0.005% by mass is more preferable. When the content of the component (b) in the detergent composition is 0.001% by mass or more and 0.01% by mass or less, the feeling of smoothness on the skin after towel-drying can be made stronger.

[0034] -(Component (c))- The content of the component (c) in the detergent composition is not particularly limited and can be appropriately selected according to the purpose. However, in terms of making the feeling of smoothness on the skin after towel-drying stronger, 0.001% by mass to 0.01% by mass is preferable, and 0.001% by mass to 0.005% by mass is more preferable. When the content of the component (c) in the detergent composition is 0.001% by mass or more and 0.01% by mass or less, the feeling of smoothness on the skin after towel-drying can be made stronger.

[0035] <At least one selected from the group consisting of dimethicone and dimethiconol> At least one selected from the group consisting of dimethicone and dimethiconol as the component (d) is mainly contained to impart a smooth feeling to the skin after towel-drying.

[0037] There is no particular limitation on the kinematic viscosity at 25°C of at least one selected from the group consisting of dimethicone and dimethiconol in the component (d), and it can be appropriately selected according to the purpose. However, from the viewpoint of the smooth feeling of the skin after towel drying, 1.5 cSt to 100,000 cSt is preferable, and 2 cSt to 1,000 cSt is more preferable.

[0038] The kinematic viscosity can be measured, for example, by the method shown below. In the following measurement method, the kinematic viscosity of dimethicone will be described, but the kinematic viscosity of dimethiconol can also be measured in the same manner. Prepare a toluene solution of dimethicone with a concentration of 1 g / 100 mL, and obtain the specific viscosity η sp (25°C) according to the following formula (1). Next, substitute it into the Huggins relational formula shown in the following formula (2) to obtain the intrinsic viscosity [η]. The Huggins constant K' is the one described in Nakamuta, Nippon Kagaku, 77, 588, 1956. Next, substitute [η] into the formula of A. Kolorlov et al. shown in the following formula (3) (see Doklady Akad. Nauk. U.S.S.R. 89 65. 1953) to obtain the molecular weight M. Finally, substitute M into the formula of A. J. Barry shown in the following formula (4) (see J. Appl. physics. 17. 1020. 1946) to obtain the kinematic viscosity η of dimethicone. η sp =(η / η0)-1 ··· Formula (1) η sp =[η]+K'[η]2 ··· Formula (2) [η]=2.15×10 -4 M 0.65 ··· Formula (3) logη=1.00 + 0.0123M0.5 ··· Formula (4) In the above formula (1), “η0” represents the viscosity of toluene, and “η” represents the viscosity of the solution. Both “η0” and “η” are measured in accordance with the first method of the viscosity measurement method in the general test method for cosmetic raw materials standards.
