摘要:
The invention relates to a continuous process for the preparation of a flavor or fragrance delivery system, wherein the presence of two heat exchangers operating respectively an evaporation and a cooling step, allow to optimize the quality and yield of the final product.
摘要:
The invention relates to sesquiterpene synthases from Patchouli plants (Pogostemon cablin), and methods of their production and use. In one embodiment, the invention provides nucleic acids comprising a nucleotide sequence as described herein that encodes for at least one sesquiterpene synthase. In a further embodiment, the invention also provides for sesquiterpene synthases and methods of making and using these enzymes. For example, sesquiterpene synthases of the invention may be used to convert farnesyl-pyrophosphate to various sesquiterpenes including patchoulol, Ϝ-curcumene and other germacrane-type sesquiterpenes.
摘要:
The present invention relates to a microorganism capable of producing a terpene of choice. The microorganism expresses a heterologous pathway for the formation of isoprene units and, preferably, a heterologous terpene synthase. In this way, high amounts of terpene can be isolated from the medium of the microorganism.
摘要:
A particularly stable perfuming composition in the form of a transparent fluid water-in-oil or oil-in-water emulsion is obtained by addition of a substance to the oily phase, capable of bringing closer the densities of the respective dispersed and continuous phases.
摘要:
One object of the invention is a spray-dried composition comprising an active ingredient dispersed in a carrier comprising a combination of a wall-forming carbohydrate material with from 1 to 30% by weight of agar agar relative to the dried weight of the composition. The composition of the invention presents an advantageous behavior in an aqueous or highly moist environment wherein the mobility of the active agent is restricted in the gelled carrier, thus preventing the release of the agent unless shear of heat are applied. Another object of the invention is a process for the preparation of the spray-dried composition.
摘要:
The present invention provides compositions and clear oil-in-water microemulsion containing up to 80% w/w of an oil, a surfactant system, a w/w oil/surfactant system ratio between 1 and 3, and a solubilizing-aid ingredient which is not a surfactant neither a VOC compound, the latter being present in an amount sufficient to ensure that the ratio oil/(surfactant+solubilizing-aid) is comprised between 0.1 and 5. The present invention concerns also the articles and products associated with said compositions and microemulsions, and the methods to manufacture them.
摘要:
An alcoholic perfume solution with an improved tenacity when applied onto a surface is described. The solution comprises an effective amount of a single polymer capable of extending the diffusion of perfuming ingredients in the air.
摘要:
The invention provides a MDGC apparatus comprising a cryotrapping means capable of cooling at least twice a portion of a chemical sample and provided with detector means disposed upstream of the cryotrap and allowing identification of the said portion of the chemical sample to control the residence time of the latter in the cryotrapping means.
摘要:
Perfuming or flavouring microcapsules comprising, further to a perfuming or flavouring ingredient and a carrier material, a fireproofing agent, proved to undergo, when suspended in hot air during their preparation, an explosion of a reduced violence.
