## Abstract

The invention includes (6E)- and (6Z)-isomers of 3,6-dimethyloct-6-en-1-ols and 6-ethyl-3-methyloct-6-en-1-ols and their mixtures. The mixtures are free from their corresponding oct-5-ene double bond isomers. Processes of preparing odorant compositions containing these compositions are also provided.

## Claims

### Claim 1

A composition comprising a mixture of compounds having the formula II:
wherein R is methyl or ethyl and which composition is free from the corresponding oct-5-ene double bond isomers.

### Claim 2 (depends on 1)

A composition according to claim 1 wherein the compounds are R-enantiomers.

### Claim 3 (depends on 1)

A composition according to claim 1 wherein the compounds are S-enantiomers.

### Claim 4 (depends on 1)

A composition according to claim 1 wherein the compounds are (6E)-3,6-dimethyloct-6-en-1-ol and (6Z)-3,6-dimethyloct-6-en-1-ol (II1):
which composition is free from (5E/Z)-3,6-dimethyloct-5-en-1-ol.

### Claim 5 (depends on 1)

A composition according to claim 1 wherein the compounds are (6E)-6-ethyl-3-methyloct-6-en-1-ol and (6Z)-6-ethyl-3-methyloct-6-en-1-ol (II2)
which composition is free from (5E/Z)-ethyl-3-methyloct-5-en-1-ol.

### Claim 6 (depends on 1)

An odorant composition comprising a composition according to claim 1.

### Claim 7 (depends on 4)

An odorant composition comprising a composition according to claim 4.

### Claim 8 (depends on 5)

An odorant composition comprising a composition according to claim 5.

### Claim 9 (depends on 1)

A process for preparing an odorant composition for use in a perfume or cosmetic composition comprising mixing an effective amount of a composition according to claim 1 with a perfume or cosmetic base.

### Claim 10 (depends on 4)

A process for preparing an odorant composition for use in a perfume or cosmetic composition comprising mixing an effective amount of a composition according to claim 4 with a perfume or cosmetic base.

### Claim 11 (depends on 5)

A process for preparing an odorant composition for use in a perfume or cosmetic composition comprising mixing an effective amount of a composition according to claim 5 with a perfume or cosmetic base.
