Abstract: The substrate for diffusing volatile substances comprises a dispersible binder and a natural material, and the percentages by weight in the dry state are: dispersible binder: 15-45%; and natural material: 55-75%. It may also comprise a preservative. It provides a substrate that provides constant and durable air diffusion properties.

Abstract: The substrate for diffusing volatile substances comprises a dispersible binder and a biodegradable material, the percentages by weight on the dry state being preferably: dispersible binder: 15-45% and biodegradable material: 55-75%. It may also comprise a biodegradable preservative such as sodium benzoate. It permits to provide a biodegradable substrate to diffuse volatile substances, which has a short biodegradation time.

Abstract: The present invention relates to a toilet cleaner comprising a cleaning agent, wherein said cleaning agent is included at a percentage between 50% and 80% by weight, and also comprising an effervescent agent at a percentage between 10% and 30% by weight. The cleaner is preferably in the form of solid granules, and it also comprises a foaming agent. The present invention allows providing a cleaner in solid form which can be applied directly in the toilet bowl and readily metered, giving the user a perception of cleanliness.

Abstract: Compounds of formula (I), where: R0 is (C8-C11)-branched alkyl, CH3—(CH2)m—, CH3—O—(CH2CH2O)2CH2—, or phenyl-(CH2)x—; m=6-10; x=1-3; R1, R3, R4, R7, and R8 are independently selected from the formula GF-(CH2)n—; with n=1-4; and GF=—NH2 or —NH—C(?NH)—NH2; R2 is —CH(CH3)(OH), —CH(CH3)2, —CH2NH2 o —CH2OH; R5 and R6 are independently selected among H, —(C1-C4)— linear or branched alkyl, —(CH2)—R10, —CH2—CH2—S—CH3 and —CH—(CH3)—OH; R9 is CONH2, —CH(CH3)(OH) or CONHR11; R10 is phenyl, 3-indolyl, 4-imidazolyl, 4-hydroyiphenyl, ? o ?-naphtyl or 2-, 3- or 4-pyridyl; R11 is a specific peptide sequence; u is CH2 or S; v is NH o S; w is CH2 or CO; with the condition that when R9 is CONH2, then (a) R5 or R6 is —CH(CH3)(OH), or (b) R5 and R6 are H; or (c) the configuration of the C bound to R9 is S or (d) the configuration of the C bound to R5 is R; and with the condition that when R9 is —CH(CH3)OH, then R8 is GF(CH2)n where n is 3 and GF is —NH—C(?NH)—NH2, and R7 is GF(CH2)n where n is 2 and GF is NH2, have been found to
