Abstract
An alkyl gycol ether having the following formula wherein R is a C1–C7 saturated, unsaturated, straight-chain or branched, acyclic or cyclic alkyl group, is useful as a fragrance material in perfumes, cosmetics, consumer products, and the like. When R is a saturated, straight-chain or branched, acyclic or cyclic alkyl group, these compounds are especially stable when used as fragrance materials in bleach containing products.
Claims23
A compound having the formula
- wherein R is a C3–C7 unsaturated, straight-chained or branched, acyclic alkyl group, a C3–C7 saturated cyclic alkyl group, or 1-methyl cyclohexene, provided that R is not a 2-propenyl group.
A fragrance composition comprising:
- a compound having the formula
- wherein R is a C1–C7 saturated, straight-chained or branched, acyclic or cyclic alkyl group or a C2–C7 unsaturated, straight-chain or branched, acyclic or cyclic alkyl group;
- and a carrier.
A method of adding fragrance to a composition, comprising:
- adding a suitable amount of a compound having the formula
- wherein R is a C1–C7 saturated, straight-chained or branched, acyclic or cyclic alkyl group or a C2–C7 unsaturated, straight-chained or branched, acyclic or cyclic alkyl group to a composition.
A method for making a compound having the formula,
- wherein R is a Ci–C7 saturated, straight-chained or branched, acyclic or cyclic alkyl group, or a C2–C7 unsaturated, straight-chained or branched, acyclic or cyclic alkyl group, provided that R is not a 2-propenyl group, comprising:
- contacting a 2,2,4-trimethyl-1,3-diol with a compound having the formula R′—X, wherein R′is a C1–C7 saturated, straight-chained or branched, acyclic or cyclic alkyl group, or a C2–C7 unsaturated, straight-chained or branched, acyclic or cyclic alkyl group provided that R is not a 2-propenyl group, X is a leaving group, in the presence of aqueous NaOH at a temperature suitable to cause a reaction in the resulting reaction mixture.
A fragrance composition comprising a compound having the formula
- wherein R is a C1–C7 saturated, straight-chained or branched, acyclic or cyclic alkyl group, or a or a C2–C7 unsaturated, straight-chained or branched, acyclic or cyclic alkyl group provided that R is not a 2-propenyl group, in combination with at least one of a carrier and an additional perfumery material.
