Japanese Patent No. 3660537 JP 2007-314454 A JP 2003-183129 A

  In powder cosmetics, when the amount of extender pigment blended as a powder component is large, the fragrance may be denatured due to the surface activity of the powder, which may cause a bad smell. Therefore, conventionally, in order to prevent the odor of the fragrance from being changed, the body pigment has been subjected to a surface treatment and used in an inactive manner. However, depending on the type of the fragrance, even if these methods are used, there is a case where the odor of the fragrance cannot be avoided, and it has been difficult to obtain a fragrance excellent in stability at a high temperature. That is, this invention makes it a subject to provide the powder cosmetics which do not change a fragrance | flavor even when there are many compounding quantities of an extender.

  As a result of intensive studies to solve the above-mentioned problems, the inventors of the present application have not changed the fragrance of the fragrance even when blended with a large amount of extender pigment by blending polyoxyethylene hydrogenated castor oil, particularly at high temperatures. The present inventors have found that the stability of the scent is improved and have completed the present invention. That is, the powder cosmetic of the present invention includes polyoxyethylene hydrogenated castor oil, 60% by mass or more of the extender pigment based on the total amount of the cosmetic, and a fragrance.

  In the powder cosmetic of the present invention, the type of extender pigment is not particularly limited, but is preferably talc. The content of the extender pigment is not particularly limited, but when the content is 60% by mass or more based on the total amount of the cosmetic, the effect of the present invention is remarkably exhibited. In the powder cosmetic of the present invention, the amount of polyoxyethylene hydrogenated castor oil is not particularly limited, but is preferably 0.01% by mass or more and 5% by mass or less, and particularly preferably 0.1% by mass with respect to the total amount of the cosmetic. The mass is 2% by mass or more. If it is less than 0.01% by mass, the effect of preventing odor change may not be sufficient, and if it is added in an amount of more than 5% by mass, the usability such as the weight of elongation, stickiness, smooth feeling, and long-lasting makeup may be impaired.

  The polyoxyethylene hydrogenated castor oil used in the present invention is generally used mainly in applications such as emulsifiers and solubilizers in the cosmetics field. Polyoxyethylene hydrogenated castor oil is a nonionic surfactant obtained by addition polymerization of ethylene oxide to hydrogenated castor oil. The number of moles of ethylene oxide added to polyoxyethylene hydrogenated castor oil used in the cosmetics field is 3 to 100. The number of added moles of the polyoxyethylene hydrogenated castor oil used in the present invention is not particularly limited, but is preferably 5 to 80, and most preferably 20 to 60.

  Hereinafter, preferred embodiments of the present invention will be described. The powder cosmetic according to the present invention is a cosmetic mainly composed of a powder component, and includes a powdery loose powder type and a pressed powder type obtained by adding a small amount of excipients to the powdered loose powder type. For example, white powder, baby powder, body powder, face powder and the like are included in the loose powder type, and solid foundation, blusher, eye shadow, eyebrow powder and the like are included in the pressed powder type. These powders are widely used in various applications such as retouching makeup and keeping the skin clean and healthy by absorbing sweat and sebum, depending on the powder to be blended. Moreover, it is used also for the purpose of suppressing a body odor while enjoying a fragrance by raising the fragrance | flavor rate of a fragrance | flavor.

Examples of the powder component to be blended in the present invention include extender pigments such as talc, kaolin, sericite, muscovite, etc. Among them, the effect of the present invention is remarkable when talc is used. The blending amount of the powder component is not particularly limited, but the odor change of the fragrance is particularly problematic when the powder component is blended by 60% by mass or more, and the effect of the present invention is remarkably exhibited.

Examples 1-4 Face powder Face powder was manufactured by the usual method with the prescription shown in Table 1. In addition, Comparative Examples 1 to 4 shown in Table 1 were produced in the same manner. In addition, a compounding quantity is shown by the mass%.

Said face powder was preserve | saved at each temperature of room temperature and 50 degreeC, and the odor change of the fragrance | flavor after 2 weeks was evaluated according to the following evaluation criteria. The evaluation was conducted by a special panel in the perfume field.
Evaluation criteria ◎: No change ○: Almost no change Δ: Somewhat changed ×: Changed The evaluation results are also shown in Table 1.

  As is apparent from Table 1, when a fragrance is blended together with talc, the fragrance is deteriorated during storage at a high temperature (Comparative Examples 1 to 4). On the other hand, when polyoxyethylene hydrogenated castor oil was blended, the odor change was suppressed, and the stability of the scent particularly during high-temperature storage was improved (Examples 1 to 4). Moreover, when talc exceeds 60%, the stability of the fragrance at the time of high-temperature storage is further lowered, but when polyoxyethylene hydrogenated castor oil is blended, the stability is improved.

Examples 5 to 9 Face powders Examples 5 to 9 and Comparative Example 4 shown in Table 2 were produced in the same manner as described above by changing the blending amount of polyoxyethylene hydrogenated castor oil, and stored at 50 ° C. for 2 weeks. In the same manner as above, the odor of the fragrance was evaluated. In addition, the usability (height of elongation, stickiness, smooth feeling, longevity) was comprehensively evaluated according to the following evaluation criteria. The evaluation was conducted by a specialist panel in the cosmetics field.
Evaluation criteria ◎: No problem ○: Almost no problem △: Somewhat inferior ×: Inferior

  As is clear from Table 2, the blended amount of polyoxyethylene hydrogenated castor oil was good in the range of 0.1 to 7% by mass with no odor of linalyl acetate at 50 ° C. If it is less than 0.01% by mass, the deodorizing effect may not be sufficient, and if it exceeds 5% by mass, the usability may be slightly impaired. A particularly preferred range in terms of fragrance and usability is 0.01 to 5% by mass. A more preferable range is 0.1 to 2% by mass.

Examples 10-15 Face powder Polyoxyethylene cetyl ether (40E.O.) was replaced with Examples 10-15 and polyoxyethylene hydrogenated castor oil shown in Table 3 by changing the number of added moles of polyoxyethylene hydrogenated castor oil. ) Was prepared in the same manner as described above, and after storage at room temperature, 40 ° C., and 50 ° C. for 2 weeks, the odor of the fragrance was evaluated in the same manner as above.

  As is clear from Table 3, the number of added moles of polyoxyethylene hydrogenated castor oil was good when no odor of linalyl acetate was observed at room temperature in the range of 2 to 100. On the other hand, polyoxyethylene cetyl ether (40E.O.) had a perfume odor change even when stored at room temperature, 40 ° C. or 50 ° C. When the polyoxyethylene hydrogenated castor oil was added in the range of 5 to 80 when stored at 40 ° C., no odor of linalyl acetate was observed, which was good. When the polyoxyethylene hydrogenated castor oil was added in the range of 20 to 60 when stored at 50 ° C., no deodorant of linalyl acetate was observed, which was good. From this result, the number of added moles of polyoxyethylene hydrogenated castor oil is particularly preferably 5 to 80 in terms of suppressing the odor change of the fragrance during high temperature storage. A more preferred range is 20-60.
