Description

  The present invention relates to a deodorant composition.

The water-based deodorant composition containing powder is characterized by a dry feeling by the powder and a refreshing feeling of use of the water-based preparation. Hydrophilic powders such as silicic acid porous porous powders are used as powders with excellent smooth feeling. However, the silicic acid porous porous powder has a problem that redispersibility in an aqueous preparation is poor and clogging occurs in a trigger container and a dispenser container. Further, when a large amount of the anhydrous silicic acid porous powder is blended in order to improve the feeling, there is a problem that bad feeling such as white residue and squeaky feeling on the skin occurs.
Therefore, as a technique for improving the redispersibility of the silicic acid porous porous powder, for example, a technique using polyether-modified silicone (see Patent Document 1), a technique in which an amphoteric polymer and a nonionic activator are combined (patent) Reference 2). In addition, as a technique for improving the clogging of the porous silicic acid porous powder, it has been proposed to add a cationic polymer or a nonionic surfactant (see Patent Document 3).
However, the techniques described in the above-mentioned prior art documents are not sufficient for improving the redispersibility of powder and eliminating clogging, and have not been solved for improving the feel of white residue and squeak. Currently.

  Therefore, it improves the redispersibility of the powder in the water-based preparation of silicic anhydride porous powder, eliminates clogging, and is excellent in a smooth feeling, lack of white residue and crispness. Therefore, it is desired to provide a deodorant composition having excellent powder adhesion to the skin.

The volume average particle diameter of the porous silicic acid porous powder is preferably 2 μm to 20 μm, more preferably 2 μm to 14 μm from the viewpoint of smooth feeling and clogging. When the volume average particle diameter is less than 2 μm, the coating tends to be peeled off during use. When the volume average particle diameter exceeds 20 μm, the feeling of smoothness is lowered and clogging may occur.
The volume average particle diameter can be measured as an arithmetic average diameter using, for example, a laser diffraction / scattering particle size distribution analyzer (for example, LS 13 320, manufactured by Beckman Coulter, Inc.).

The specific surface area of the silicic anhydride porous ^powder, 200m ² / ^g~800m 2 / g are ^preferred, and more preferably 250m ² / g~700m 2 / g.

The silicic anhydride porous powder can be synthesized by an interfacial reaction method. In the interfacial reaction method, a water-in-oil emulsion (emulsion) is formed with an organic solvent and a surfactant in an inorganic compound aqueous solution, and this is mixed with another aqueous solution to cause a precipitation reaction at the water droplet interface. After the formation of the inorganic shell, the anhydrous silicic acid porous powder can be synthesized by removing reaction by-products and surfactants.

That is, since the (B) silicone resin powder has a rubber structure inside and has flexibility not found in other powders, it is a problem of the (A) anhydrous silicic acid porous powder. The redispersibility and clogging of powder can be improved. Furthermore, since the flexibility of the (B) silicone resin powder can give a soft and smooth feel to other powders, the white residue which is a problem of the (A) silicic acid porous porous powder The smoothness and the feeling of squeak are improved. Furthermore, since hydrophobic powder has the property of remaining on the skin more easily than hydrophilic powder, (A) Silicic acid porous porous powder can be obtained by blending (B) silicone resin powder at a specific ratio. It is assumed that the adhesion of the powder to the skin is improved and the feeling of smoothness is improved.
Therefore, the mass ratio (B / A) of the content of the component (A) and the component (B) determines the redispersibility of the powder, prevention of clogging, a feeling of dryness, and adhesion of the powder to the skin. From the point of property, it is 0.5-15, and 1-10 are preferable. When the mass ratio (B / A) is less than 0.5, the redispersibility of the powder is deteriorated, and clogging is likely to occur, and a squeaky sensation occurs, and the powder adheres to the skin If it exceeds 15, the feeling of smoothness is weak and the adhesion of the powder to the skin may be inferior.

<Antiperspirant effect>
About 0.1 g of each of the prepared deodorant compositions was applied to the forearm inner part (length × width: 3 cm × 3 cm) of 20 female professional panels in their 20s to 30s. After each deodorant composition was dried, light exercise was performed for 20 minutes in an environment of 42 ° C. and 50% RH. Then, using a sweat meter (SKN-2000, manufactured by Nishizawa Denki Keiki Seisakusho Co., Ltd.), the amount of sweat in the sample application part and the sample unapplication part in the vicinity thereof is measured, and the antiperspirant rate (%) is obtained from the following formula. The average value of 20 people was calculated. From the results of the obtained antiperspirant rate (%), the antiperspirant effect was evaluated according to the following criteria.
[Criteria]
◎: Antiperspirant rate is 40% or more and 100% or less ○: Antiperspirant rate is 30% or more and less than 40% △: Antiperspirant rate is 20% or more and less than 30% ×: Antiperspirant rate is 0% or more and less than 20%

  Next, details of each component used in Examples and Comparative Examples are as described in Table 9 below.

* The anhydrous silicic acid porous powders A to D of the component (A) were dispersed in the aqueous phase when 1 g of the powder was added to 10 g of hexane / 10 g of water and ultrasonically dispersed. Therefore, both are hydrophilic powders.
* The silicone resin powders A to E as the component (B) were dispersed in the hexane phase when 1 g of the powder was added to 10 g of hexane / 10 g of water and ultrasonically dispersed. Therefore, both are hydrophobic powders.

  The deodorant composition of the present invention improves the redispersibility of the powder in the aqueous preparation of the anhydrous silicic acid porous powder, eliminates clogging, and is excellent in smooth feeling, lack of white residue and squeaky feeling. It is suitable for use in, for example, a deodorant spray, a water spray, and an antiperspirant deodorant mist.
