20090238785 | Novel Aldehydic Musks and Derivatives Thereof - A compound comprising a Schiffs base of an aldehydic musk aromachemical with a substantially nonvolatile, odorless amine, wherein the imine moiety of said Schiffs base compound is stable against oxidation to a carboxyl group or a mixture of said compounds; said Schiffs base compound being biodegradable over time to said aldehydic musk and said nonvolatile, odorless amine; as well as compositions, products, preparations or articles having improved aroma, fragrance or odor characteristics containing as active ingredient such compound or mixture of compounds; the aldehydic musks themselves, and methods for the preparation of the Schiff bases and methods of imparting fragrance characteristics to substrates. | 09-24-2009 |
20090317529 | Aromachemicals and Processes for Preparation - Aromachemical compounds of Formula I, compositions comprising these compounds and processes for their preparation are disclosed, | 12-24-2009 |
20100087356 | Aromachemicals - Improved aromachemical derivatives, and fragrances and flavorings including the derivatives, that have a longer useful shelf life than the aromachemicals from which they can be derived, are disclosed. In particular, the derivatives maintain the fragrance characteristics of the aromachemicals, while lowering the allergic properties, increasing the stability, and/or increasing the odor intensity. Also disclosed are methods of making the derivatives, and articles of manufacture including the derivatives. In one embodiment, the derivatives are prepared by replacing one or more double bonds in citral with a thioether, cyclopropyl, oxirane, or thiirane group. The cyclopropane ring can be unsubstituted, or substituted with one or two lower alkyl, preferably methyl groups. The alkyl groups can optionally be substituted, for example, with electron donating groups, electron with drawing groups, groups which increase the hydrophilicity or hydrophobocity, and the like. In another embodiment, the derivatives are prepared by replacing the aldehyde group in the essential oil with a nitrile, methyl ether or acetal group. The acetal groups can provide the compounds with a long lasting flavor or fragrance, where the acetals slowly hydrolyze to provide the aldehyde group in the parent essential oil. In some embodiments, both the aldehyde and at least one of the double bond functional groups are both derivatized as described herein. Examples of suitable articles of manufacture include candles, air fresheners, perfumes, disinfectant compositions, hypochlorite (bleach) compositions, beverages such as beer and soda, denture cleanser tablets and flavored orally-delivered products such as lozenges, candies, and the like. | 04-08-2010 |

20080305976 | Color-Stabilization of Aromachemicals - The use of at least one water-soluble sulfiting agent to reduce or prevent the discoloration of an aromachemical, odorant, flavorant or perfume component susceptible to discoloration. | 12-11-2008 |
20090016976 | CITRAL AND CITRONELLAL DERIVATIVES - Improved citral and citronellal derivatives, and fragrance and flavorings including the derivatives, that have a longer useful shelf life than citral and citronellal and/or fragrances and flavoring including citral and citronellal, are disclosed. In particular, the derivatives maintain the fragrance characteristics of citral and citronellal, while lowering the allergic properties, and lemony flavors and fragrances with a longer shelf-life than citral and citronellal, are disclosed. Also discovered are methods of making the derivatives, and articles of manufacture including the derivatives. The derivatives replace the aldehyde group in citral or citronellal with a hydroxy group. In one embodiment, the derivatives also replaced one or more double bonds in citral or the double bond in citronellal with a cyclopropyl group, which can be unsubstituted, or substituted with one or two alkyl, preferably methyl, groups, or with an oxirane or thiirane ring or combinations thereof. The alkyl groups in the cyclopropyl groups can optionally be substituted, for example, with electron donating groups, electron withdrawing groups, groups which increase the hydrophilicity or hydrophobicity, and the like. Examples of suitable articles of manufacture include candles, air fresheners, perfumes, disinfectant compositions, hypochlorite (bleach) compositions, beverages such as beer and soda, denture cleanser tablets and flavored orally-delivered products such as lozenges, candies, and the like. | 01-15-2009 |
20090162495 | Derivatives of Di-Carbonyl Aromachemicals - An improved method for imparting a flavor to a product, the method comprising adding to the product an organoleptically effective amount of a dicarbonyl or a mixture thereof, the improvement comprising substituting for the dicarbonyl, an organoleptically acceptable derivative thereof having the formula (I) or (II), wherein m=0, 1 or 2, n=1 or 2, R | 06-25-2009 |
20090208627 | Diacetyl Derivatives - An improved method for imparting a butter flavor to a product, the method comprising adding to the product an organoleptically effective amount of diacetyl, the improvement comprising substituting for the diacetyl, an organoleptically acceptable derivative of diacetyl having the formula: (formula I), or an organoleptically acceptable salt thereof, as well as compositions for carrying out the method and products and articles of manufacture comprising the additive. | 08-20-2009 |
