ABSTRACT:
TECHNICAL FIELD
The present invention relates to a novel fragrant compound and a perfume composition containing the compound. More specifically, the present invention pertains to 5-benzylhexanol-2 which has a floral scent and excellent lasting property in a mixture system of each of fragrant products such as toiletry products, household products and personal care products.
BACKGROUND ART
A number of perfume materials with a floral scent have conventionally been known. Among them, aroma chemicals with aldehyde moiety, typified by Lilial, are greatest in number and besides, they form an important category. They are however not always stable in fragrant products which have various pHs or various product forms. Accordingly, it is often difficult to impart the products with freshness, natural feeling, mildness, voluminous feeling or stable lasting property and there is a limitation in the perfume preparation.
In addition, many floral aroma chemicals with alcohol moiety have been known and the typical example of them is phenethyl alcohol. Phenethyl alcohol itself is poor in lasting property so that it cannot easily impart perfumery products with a stable lasting scent.
Accordingly, an object of the present invention is to provide a novel compound which has a floral scent, high stability and excellent lasting property in a mixture system; and also a perfume composition comprising the compound.
DISCLOSURE OF THE INVENTION
Under such situations, the present inventors synthesized compounds having various functional groups and investigated their scents and mixture systems. As a result, it has been found that 5-benzylhexanol-2 which is a novel compound represented by the below-described formula has a floral scent, and in the mixture system of a product, has freshness, natural feeling, mildness, voluminous feeling and stable lasting scent, leading to the completion of the present invention.
The present invention therefore provides 5-benzylhexanol-2 represented by the following formula (1):
and a perfume composition comprising the same.
