Description

  The present invention relates to an external preparation for skin, and more particularly to an external preparation for skin in which one or more oily components obtained from a specific plant are blended in the external preparation for skin to mask a base odor caused by raw materials. It is.

In conventional external preparations for skin, the fragrance has been formulated for the purpose of masking the odor of the raw material itself (base odor) and for the purpose of enjoying the fragrance itself. Gradually changed to slightly scented and unscented. However, a variety of raw materials such as natural products and synthetic products are used in conventional skin external preparations, and it has been essential to reduce the base odor of the raw materials. Therefore, masking agents for extracts obtained from specific components and specific plants have been proposed. For example, one or more masking agents selected from orange oil, Sawtooth grass extract, Merirot extract, lemon extract, and apple extract are blended in unscented cosmetics and unscented detergents ( Similarly, refer to Patent Document 1) Similarly, two or more kinds selected from oily ingredients and / or aqueous ingredients of orange flour, cypress, lavender and rosemary are blended in the skin external preparation to mask the base odor of the raw material. The content of (refer patent document 2) is disclosed. However, many masking agents themselves have a specific scent, and even if the base odor can be reduced to some extent, there is a restriction that only a skin external preparation with the same fragrance can be obtained as a result. Is also true. Therefore, in Patent Document 3, Yakuyo Salvia as a masking agent is used as a masking agent that reduces base material odor and deterioration odor over time caused by cosmetic raw materials and has little influence on the fragrance of the combined fragrance. (Sage) Sage oil obtained by steam distillation of leaves of [ Salvia officinalis L.] is disclosed.

  However, the conventionally known masking agents are not satisfactory because of insufficient effects. In addition, it has not been possible to mask the base odor caused by one or more selected from ascorbic acid and its derivatives and salts thereof in skin external preparations, and the deterioration odor generated over time.
