JPH07238295A - Tertiary alcohol-containing pepfume composition - Google Patents

Abstract

PURPOSE:To obtain the subject new composition containing a specific tertiary alcohol having characteristic aroma with refreshing feeling, useful as a long- acting aroma-providing agent or a modifier, etc., for various compounded perfumes. CONSTITUTION:This composition contains a tertiary alcohol of the formula (R is cyclohexyl or neopentyl) (namely, 2-cyclohexyl-2-propyl alcohol or 1,1,3,3- tetramethylbutyl alcohol). 2-cyclohexyl-2-propylalcohol is preferably obtained by hydrogenating 2-phenyl-2-propyl alcohol. 1,1,3,3-tetramethylbutyl alcohol is preferably obtained using diisobutylene as a raw material. Furthermore, the compound of the formula is usually blended in an amount of 0.01-30wt.% based on total amount of perfume composition.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a perfume composition in which an aroma substance that can be used as a perfume is mixed with other synthetic and natural aroma components.

[0002]

2. Description of the Related Art Conventionally, as tertiary alcohols, for example, tertiary butyl alcohol and tertiary amyl alcohol have been known, but few examples of using them as aroma substances have been known. Examples of the use of tertiary alcohols as aroma substances include linalool, myrcenol, aloosimenol, isophytol and the like, and JP-B-4-60454 discloses 1,1,2,
An example of 2-tetramethylpropanol is disclosed.

Means for Solving the Problems The inventors of the present invention have conducted intensive studies for the purpose of developing a fragrance composition that meets the above-mentioned demand, and as a result, have achieved the purpose by incorporating a tertiary alcohol shown below. The present invention has been completed based on the finding that the above can be achieved. That is, the present invention has the general formula

[Chemical 2] A fragrance composition comprising a tertiary alcohol represented by the formula (wherein R represents a cyclohexyl group or a neopentyl group).

Specific examples of the tertiary alcohol represented by the above [formula 2] are 2-cyclohexyl-2-propyl alcohol and 1,1,3,3-tetramethylbutyl alcohol. There are no examples where these compounds were used as aroma substances.

The above-mentioned 2-cyclohexyl-2-propyl alcohol can be obtained by hydrogenating 2-phenyl-2-propyl alcohol. Also 1,1,3,3-
Tetramethylbutyl alcohol is a journal of
American Chemistry (J. Am. Chem. So
c. ) Volume 75, page 10 (1953) and journals
Of American Chemistry (J. Am. Che
m. Soc. ), 100, 1865 (1978)
It can be produced using diisobutylene as a raw material by the method described in, for example.

The present inventors have found that 2-cyclohexyl-2-propyl alcohol is like camphor,
3-Tetramethylbutylalcohol has a unique scent that is like a mackerel and has a refreshing sensation, so we got the idea that it would be useful as a new scent substance, and its characteristics were confirmed as illustrated below. Was done. That is, it can be used as it is as a fragrance composition such as an aroma-imparting agent, or can be used as a fragrance composition by mixing with a base agent, a blending agent, a modulator of a prepared fragrance, and other fragrance ingredients as a stabilizer. You can also Further, the perfume composition of the present invention as an aroma-imparting agent or a flavor-imparting agent, for example, cosmetics, aromatic agents, perfumes, detergents, soaps,
It can also be added to shampoos and conditioners.

The fragrance composition of the present invention includes, for example, bergamot oil, lemon oil, geranium oil, mandarin oil,
Synthetic essential oils such as lavender oil, orange oil, lime oil,
Natural essential oils such as lemon oil, grapefruit oil, oak moss oil, citronella oil, vetiver oil, cinnamo oil, patchouli oil, clove oil, bergamot oil, and rose oil are blended with the tertiary alcohol represented by the above [Chemical formula 2]. The top tuned superior fragrance composition can be demonstrated. Furthermore, natural and synthetic fragrance substances, for example, aldehydes such as hydroxycitronellal, n-decanal, citral and heliotropin, ketones such as α-ionone, p-methylacetophenone and benzalacetone, phenyl. Acetals such as acetaldehyde dimethyl acetal, linalool, geraniol,
Alcohols such as nerol, benzyl alcohol, and terpineol, ethers such as safrole, 1-methylcyclododecan-1-ylmethyl ether, benzyl acetate, linanyl acetate, esters such as methyldihydrojasmonate, coumarin, γ- Lactones such as undecalactone, and mixed fragrances containing two or more of them, for example, fragrance compositions such as jasmine, rose, suzuran, lira, violet, mokuse, carnation, muguet, lavender, strawberry, lemon. , Orange, grapefruit, apple,
By blending a flavor composition such as pineapple with the above-mentioned tertiary alcohol, a fragrance composition having a mild and long-lasting property can be prepared.

The above-mentioned tertiary alcohols are highly useful for perfume compositions in terms of aroma components and retention properties, and the amount of the tertiary alcohols in the composition varies depending on the purpose, but usually 0.01 to 30% by weight. Used in the range of%.

EXAMPLES Next, the present invention will be described in detail with reference to examples.

Example 1 A rose-tone basic composition was prepared by mixing the following components (parts by weight). A fragrance composition was prepared by mixing 5 g of 2-cyclohexyl-2-propyl alcohol with 100 g of the above composition. The fragrance of this product was sharp and a novel rose-like compounded fragrance having a soft and fresh feeling was obtained. Furthermore, five expert panelists examined the change in aroma after one month with and without addition of 2-cyclohexyl-2-propyl alcohol. As a result, the fragrance of the non-added one was changed, whereas the change of the added one was not observed.

Example 2 A jasmine-like base composition was prepared by mixing the following components (parts by weight). A fragrance composition was prepared by mixing 100 g of the above composition with 10 g of 1,1,3,3-tetramethylbutyl alcohol.
The scent of this product has a soft and fresh sensation, and
A new jasmine-like compounded fragrance with improved natural feeling was obtained. Further, when a sensory test was performed on the change in aroma between the added product and the non-added product as in Example 1, 1, 1, 3,
The addition of tetramethylbutyl alcohol had improved sustainability.

Example 3 A base composition of a tin-lan type was prepared by mixing the following components (parts by weight). A fragrance composition was prepared by mixing 100 g of the above composition with 10 g of 2-cyclohexyl-2-propyl alcohol. The fragrance of this product was mild, and a novel lily of the valley-like compounded fragrance having excellent durability was obtained.
