摘要:
Compounds of the Formula I, wherein A1 is O or NH; A2 is O or S; each of R1 and R2 is independently hydrogen, a methyl or C2-C8-saturated or mono- or doubly unsaturated, branched or linear hydrocarbon group; and R3 is a C1-C18-saturated or mono- or doubly unsaturated, branched or linear hydrocarbon group wherein, each of R1, R2 and R3 comprises a heteroatom selected from the group consisting of O and S in the chain and/or is mono- or multiply-substituted by a substituent selected from the group consisting of halogen, hydroxy, C1-C6-alkyl, trifluoromethyl, C1-C6-alkoxy, C6-C10-aryl, and C1-C6-alkyl-C6-C10-aryl are useful for controlling the interaction process between microorganisms such as in the development and/or maturation of biofilms; multicellular swarm behavior; the concerted development of antibiotic resistances; the concerted synthesis of antibiotics; the concerted synthesis of pigments; the concerted production of extracellular enzymes; or the concerted production of virulence factors.
摘要:
Cosmetic composition comprising at least one compound from advanced glycation end products (‘AGEs’) and/or precursors thereof as an agent for skin treatment, especially for protection and/or care of the skin. The present invention further provides a cosmetic composition comprising at least one compound from the group of the AGEs and/or precursors thereof, wherein the AGEs are prepared by reacting sugars with the amino acids lysine and/or arginine.
摘要:
The invention relates to a method for restructuring keratin fibers during which a keratin fiber is brought into contact with cystine and with at least one dicarboxylic acid having 2 to 10 carbon atoms. The invention also relates to preparations for use in this method.
摘要:
Photolabile fragrance storage substances capable of the photo-induced release of cyclic compounds having semi-cyclic double bonds are described. Further described is a method for sustained scenting of surfaces and a method for production of said fragrance storage substances.
摘要:
The present invention relates to the use of superoxide dismutases to remove Amadori and Maillard products, and to washing and cleaning agents that contain superoxide dismutases.
摘要:
1-aza-3,7-dioxabicyclo[3.3.0]octane compounds, process for their preparation, their use as pro-fragrances, and washing and cleaning compositions, fabric softeners and cosmetics comprising them, and a process for prolonging the odor perception of such compositions.
摘要:
Bad odors on textile materials are often caused by body odor. The invention relates to a textile material treatment method for inhibiting body odor on textile materials, by which means the treated textiles, after having been worn, even after sweat-inducing sports activities, have a significantly reduced bad odor or even no odor. The invention also relates to a perfume composition and to a textile material treatment agent, respectively comprising urea derivatives and/or phenacylthiazolium salts, that counteract the formation of body odor.
摘要:
Silicic acid esters to which fragrances are bound, preferably as 1-aza-3,7-dioxabicyclo[3,3,0]octane compounds or as monocyclic oxazolidines and that are suitable for adding fragrance to detergents and cleaning agents because they release the bound fragrances in hydrolysis.
摘要:
Scents having a fresh odor are usually very volatile, and therefore have a low yield in typical applications such as washing or cleaning processes. They must therefore be used in relatively large quantities so that commensurate effects can be achieved. The invention describes specific ketones as photolabile scent storage substances which enable greatly improved persistence of the scent impression, in particular with a fresh odor, in typical applications. Corresponding washing or cleaning agents and air freshening agents, and a method for scenting surfaces, are also described.
