Description

  The present invention relates to a novel scent retention agent and a scent retention method, and more specifically, a scent retention agent containing an organically modified clay mineral and ethanol treated with a quaternary ammonium salt, and the scent retention agent and any The present invention relates to a method for easily enhancing the scent sustainability (holding property) by applying a fragrance composition to the body.

Conventionally, in a fragrance composition to be applied to the skin, liquid perfume mainly composed of fragrance and alcohol, eau de cologne, fragrance powder mainly composed of fragrance and powder, solid form mainly composed of fragrance and oil. Perfumes are known.
There was a strong demand for users of these fragrance products to keep their favorite scent forever, and when the scent disappeared, they often felt inconvenience in reattaching the fragrance product.
Under such circumstances, a retaining agent has been conventionally used in the fragrance composition for the purpose of delaying the volatilization rate of the fragrance and maintaining the fragrance in good balance. The retentive agent itself is difficult to volatilize itself, has good compatibility with other volatile fragrances, has the effect of slowing its volatilization rate, and should not impair the fragrance. Originally, odorless ones are preferred. Various studies have been conducted on the retention agent so far, including solvents such as diethyl phthalate, alkylene glycol, alkyl citrate, benzyl benzoate, musk, sandalwood, perubalsum, benzoin, labdanum, oak moss, patchouli, etc. Natural fragrances have been used. However, they are already blended in various fragrance products, and a method for easily maintaining the fragrance of any fragrance composition has not been established so far.

Therefore, in order to enhance the fragrance retention of any fragrance composition, before using the fragrance composition, the effect is obtained by applying a composition that is expected to have a fragrance retention effect, that is, a fragrance retention agent to the skin or the like. It was thought to get. However, when solvents and oils that are expected to have a scent retention effect are applied as an oily composition or an emulsified composition, there are problems with the feeling of use such as stickiness and the base material odor of the oil, and the scent of the fragrance composition There was a fact that the holding effect was not satisfactory.
That is, the object of the present invention is to apply a scent retention agent before and after use of any fragrance composition, or simultaneously, to enhance the scent retention property of any fragrance composition, and a scent retention agent having a high scent retention effect. Is to provide.

In such a situation, as a result of intensive studies to solve the above problems, the present inventor applied a scent retention agent containing a specific organically modified clay mineral and ethanol before using any fragrance composition, It has been found that the retention (sustainability) of any scent can be increased.
That is, the present invention comprises (A) an organically modified clay mineral obtained by treating a smectite-type clay mineral with a quaternary ammonium salt, (B) a scent retention agent characterized by containing ethanol, and The present invention relates to a scent retention method characterized in that a scent retention agent and an arbitrary fragrance composition are applied to the body to increase the persistence of the scent.

  The scent retention agent and scent retention method of the present invention can easily maintain the scent of any fragrance composition.

Hereinafter, the present invention will be described in detail.
The organically modified clay mineral of component (A) used in the present invention can be obtained by treating a smectite type clay mineral with a specific quaternary ammonium salt. As the smectite type clay mineral, any layered silicate having interlayer cation exchange ability and having the property of taking water between layers and swelling can be used. For example, montmorillonite, beidellite, nontronite Natural or synthetic clay minerals such as saponite and hectorite can be used.

The quaternary ammonium salt as the treating agent for the organically modified clay mineral of component (A) is specifically polyoxyethylene having at least one functional group bonded to a quaternary ammonium nitrogen atom having a polymerization degree of 1 to 50. A quaternary ammonium ion that is a group and / or a polyoxypropylene group and at least one functional group is a hydrocarbon group having 1 to 20 carbon atoms. for example, Cl-, Br-, NO ₃ - can be exemplified salts with such. Particularly preferably, of the four functional groups bonded to the quaternary ammonium nitrogen atom, three are the same or different alkyl groups having 1 to 6 carbon atoms, and the remaining one functional group is a polyalkylene having a polymerization degree of 1 to 50. It is an oxypropylene group. As a commercial item, Adeka Coal CC-9, CC-36, CC-42 (above, Asahi Denka Kogyo Co., Ltd. make) etc. can be mentioned. The component (A) modified with these treatment agents is preferable because the gel composition containing the component (B) as a swelling medium has high transparency and excellent aesthetics.

The method for producing the organically modified clay mineral of component (A) can be obtained by performing a general cation exchange between layers. For example, a method in which a smectite type clay mineral is dispersed in water, a quaternary ammonium salt solution is dropped, and the reaction is sufficiently stirred to complete the reaction, followed by solid-liquid separation, water washing, drying, and pulverization. .
As the component (A), the organically modified clay mineral may be used alone or in combination of two or more as required. Specific examples of commercially available products include Lucentite SPN and Lucentite SEN (both manufactured by Co-op Chemical).

  The compounding amount of the organically modified clay mineral of the component (A) used in the scent retention agent of the present invention is 0.5 to 25% by mass (hereinafter simply indicated by “%”) in the total amount of the composition. If it is less than 0.5%, there is a problem in usability because the viscosity of the composition is low, and the scent retention effect is not satisfactory. On the other hand, when it exceeds 25%, the feeling of use such as stretch and stickiness is deteriorated.

  The component (B) ethanol used in the present invention is blended as a swelling medium for the component (A) organically modified clay mineral. The component (A) and the component (B) are thickened into a transparent gel when mixed. As a result, the scent retention agent of the present invention is free from sagging and is excellent in usability. Although the compounding quantity of the ethanol of a component (B) is not specifically limited, Preferably it is 80-99.5% in the composition whole quantity.

  In addition to the above essential components, the scent retention agent of the present invention is a component generally blended in cosmetics, for example, water, a water-soluble humectant, and an oil agent, as long as the effects of the present invention are not impaired depending on the purpose. , Surfactants, powders, gelling agents, cosmetic ingredients, antioxidants, preservatives, chelating agents, pH adjusters, medicinal ingredients, and the like can be appropriately blended.

The scent retention method of the present invention increases the sustainability of any scent by applying the scent retention agent of the present invention and any fragrance composition to the body, but the application order is not limited, and any fragrance The scent retention agent can be applied before or after use of the composition.
Moreover, although the scent retention agent of this invention can be used also with a tube or a jar bottle specification, when it fills and uses a spray container, it can apply | coat uniformly, a hand does not get dirty, and can obtain the target effect more simply.

  The following examples further illustrate the present invention. In addition, these do not limit this invention at all.
