Item Formulación de un adyuvante agrícola a partir de fuentes biodegradables(Universidad Santiago de Cali, 2019) Guampe, Sandra Milena; Gutiérrez Moreno, Nini Johanna (Directora)The development of new technologies will develop new products used for the protection of crops such as pesticides. Over time to improve life, thanks to the use of adjuvants containing non-biodegradable sources that contribute to the contamination of soil, water, etc. To help reduce the environmental impact, what we are looking for with this project is an agricultural adjuvant system based on biodegradable raw materials and renewable sources to obtain a product with no contents of ethoxylated nonylphenols and toxic flammable solvents derived from petroleum. The product was developed in the research and development laboratory located in the facilities of the GROW CHEMICAL GROUP plant in Candelaria, for which the manufacturing know-how and the appropriate materials were used to obtain a homogeneous product. It was characterized by physical-chemical analysis such as: appearance where the color and aspect of the product were appreciated, the pH on a 5% solution in distilled water, the solids were taken in a solids analyzer, taking one gram sample for each analysis, the density was determined with a hydrometer at 25 ° C and the humidity was taken in Karl Fischer moisture equipment. In addition, emulsion stability tests were carried out according to the NTC 292 standard and encapsulation test. At the end an adjuvant was obtained, elaborated with biodegradable raw materials and that fulfilled a basic requirement of commercial acceptance: stability norm NTC 292 and encapsulation test.
