2524 results about "Propionate" patented technology

The propionate /ˈproʊpiəneɪt/, or propanoate ion, is C₂H₅COO⁻ (the conjugate base of propionic acid). A propionic, or propanoic, compound is a small salt or ester of propionic acid. In these compounds, propionate is often written in shorthand, as CH₃CH₂CO₂ or simply EtCO₂.

Gene products of bacillus licheniformis which form odorous substances and improved biotechnological production methods based thereon

The present invention relates to 25 hitherto undescribed genes of B. licheniformis and gene products derived therefrom and all sufficiently homologous nucleic acids and proteins thereof. They occur in five different metabolic pathways for the formation of odorous substances. The metabolic pathways in question are for the synthesis of: 1) isovalerian acid (as part of the catabolism of leucine), 2) 2-methylbutyric acid and/or isobutyric acid (as part of the catabolism of valine and/or isoleucine), 3) butanol and/or butyric acid (as part of the metabolism of butyric acid), 4) propyl acid (as part of the metabolism of propionate) and/or 5) cadaverine and/or putrescine (as parts of the catabolism of lysine and/or arginine). The identification of these genes allows biotechnological production methods to be developed that are improved to the extent that, to assist these nucleic acids, the formation of the odorous substances synthesized via these metabolic pathways can be reduced by deactivating the corresponding genes in the micro-organism used for the biotechnological production. In addition, these gene products are thus available for preparing reactions or for methods according to their respective biochemical properties.

Melamine-formaldehyde microcapsule slurries for fabric article freshening

Described is a method for freshening fabric articles by means of spraying the articles with an aqueous slurry of microcapsules having rupturable melamine-formaldehyde polymeric walls, containing substantive and efficacious functional substances, e.g., malodour counteractants and/or fragrances. The slurry may optionally contain non-confined functional substances, e.g. malodour counteractants and/or fragrances. The method is effective for the deposition of effectively-rupturable malodour suppressant and/or fragrance emitting microcapsules onto fabrics wherein the resulting emitted fragrance activity and/or malodour counteractant activity is long-lasting and where the resulting substantive aroma is aesthetically pleasing over the long period of time for which it is effective. Also described are efficacious and substantive malodour counteractant compositions useful for the aforementioned process containing a malodour composition composed of zinc ricinoleate and at least one of: 1-cyclohexylethan-1-yl butyrate; 1-cyclohexylethan-1-yl acetate; 1-cyclohexylethan-1-ol; 1-(4′-methylethyl)cyclohexylethan-1-yl propionate; and/or 2′-hydroxy-1′-ethyl(2-phenoxy)acetate. In addition, described are efficacious microcapsule slurries useful for the aforementioned process containing microcapsules having melamine-formaldehyde polymeric capsule walls with the microcapsules being in contact with one or more polymeric silicone phospholipids.
