Abstract: A mixture of alkylesters of fatty acids is provided, wherein the fatty acids have the following composition: at least 56% of saturated C12 chains, at least 23% of saturated C14 chains, at most 8% of saturated C16 chains, at most 5% of saturated C6-10 chains, at most 5% of monounsaturated C18 chains, at most 2% of saturated C18 chains, at most 0.8% of diunsaturated C18 chains, and at most 0.2% of saturated C20 chains. The percentages are an average percentage expressed in number of moles per total number of moles of alkylesters, and the use of these mixtures is as a viscosity agent.

Abstract: The invention concerns a combination of ingredients comprising a fraction of palm, a fraction of bamboo, a fraction of an aquatic plant, a fraction of tropical forest tree, milk, feather and urine and/or earthworm excrements, said ingredients having undergone fermentation, as well as its use as phytosanitary composition and in particular fertilizer and the manufacture of a sanitary composition.
