C'est un terme générique qui rassemble les insecticides, les fongicides, les herbicides, les parasiticides. Produits naturels Index. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : Microemulsions are preferred over conventionally used pesticide systems for their long term thermodynamic stability, low viscosity, cost economy and aesthetic appeal. Such systems provide a method for preparing an isotropic mixture of oil and water. Neem and Karanjia isolates have proven activities. Therefore, uses of these oils provide a biologically and environmentally acceptable pesticide formulation. The present investigation deals with the systematic study to arrive at the economical composition for formulating microemulsion systems using these oils. These microemulsions, when diluted with water, formed macroemulsions which were stable over an extended period of time.

Application of neem oil in alkyd and polyurethane formulation / Ashutosh in PAINTINDIA, Vol. LXVIII, N° 7 (07/2018)  

[article]  inPAINTINDIA > Vol. LXVIII, N° 7 (07/2018) . - p. 79-83 Titre : Application of neem oil in alkyd and polyurethane formulation Type de document : texte imprimé Auteurs : Ashutosh, Auteur ; Mishra Ankit, Auteur ; Mriza Fazlurrahman Beg Année de publication : 2018 Article en page(s) : p. 79-83 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Affinage Formulation (Génie chimique) Huile de neem Neem et constituants Polyalkydes Polyuréthanes Revêtements:Peinture Index. décimale : 667.9 Revêtements et enduits Résumé : Recently, the use of renewable sources in the preparation of various industrial materials has been revitalized because of the environmental concerns. Natural oils are considered to be the most important class of renewable sources. They can be obtained from naturally occurring plants, such as sunflower, neem, cotton, linseed. They consist predominantly of triglycerides. To demonstrate the applicability of neem oil in modern paint formulations, we prepareD a long nee oil alkyd resin,which is the work horse of the paint industry, followed by treatment of the polymer with Toluene di-isocyanate to form a poly urethane polymer.

Synthesis, characterization and antifungal activities of copper(II) soaps and their complexes derived from azadirecta indica (neem) and pongamia pinnata (karanj) oil / R. Sharma in TENSIDE, SURFACTANTS, DETERGENTS, Vol. 46, N° 3/2009 (05-06/2009)

Langues : Anglais (eng) Catégories : Antifongiques Antiseptiques Benzothiazoles Candida Caractérisation Huile de karanja et constituants Huile de neem Savon Surfactants Surfactants -- Toxicologie Tests de toxicité Index. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : Neem (Azadirecta indica) and Karanj (Pongamia pinnata) oils are ecofriendly, non-toxic, completely biodegradable with antiviral, antifungal, and antibacterial properties. The dark green colour Copper(II) soaps derived from Neem and Karanj oil, their greenish brown complexes with ligand 2-amino-6-methyl benzothiazole containing nitrogen and sulphur have been synthesized and characterized by elemental analysis. IR and NMR of complexes suggest that the complexation has taken place successfully. From the analytical data the stoichiometry of the complexes has been observed to be 1:1 (metal-ligand). Copper soaps and their complexes are good anti-fungal agents. The fungi toxicities of the oils, soaps and complexes of neem and karanj have been investigated. The results indicate that the strain of Candida species is susceptible towards complexes of benzothiazole.
