Lamberti Oleochemicals and Surfactants

  1. 1. Lamberti | the value of custom-made chemistry - Technologies/Oleochemicals, Surfactant... Page 1 of 2 MSD S Search Home > Technologies > Oleochemical Derivatives Oleo technology serves all Lamberti market sectors providing finished products and intermediates via: ALKOXYLATION (EO, PO, block & random addition) ESTERIFICATION (Phosphation, Sulf(on)ation, Carboxylic Esters, Esters of Alkyl-PolyGlucosides) SULFITATION (Succinic esters, Fatliquors) AMIDATION BLENDING Central R&D, based in Albizzate Italy, develops and tailors products (all reaction types) from lab. to pilot scale up to industrial production. Local laboratories and Research Application Labs (RSA) supports productions and markets. Production is present in all geographical areas, i.e.: ALKOXYLATION: Italy , USA ESTERIFICATION, AMIDATION, SULFITATION, BLENDING: Italy, Spain, USA, Mexico, Brazil, China Main applications: NON-IONIC & ANIONIC SURFACTANTS for I&I, Personal Care, Textile, Leather: By definition a surfactant decreases the surface tension of a medium and in particular of water. In our markets the surfactant is quite often identified with the foam it produces. By different addition of EO (and PO) to a fatty alcohol (linear or branched) or to other backbones, or by sulf(on)ation of non-ionics we can obtain different types of foam: from the soft with big bubbles of a shampoo to the very thick and persistent of a shaving creams or to the controlled and non-persistent for textile and leather applications . EMULSIFIERS for Textile, Pulp & Paper, Agrochemicals, Personal Care & Cosmetics, Oil, Mining, Drilling, Leather, Emulsion Polymerization Oil in Water (O/W) and Water in Oil (W/O), direct and inverse emulsions are heterogeneous systems whose formation, stability and performance depend on the correct choice of emulsifiers. HLB ( Hydrophilic-Lipophilic balance) is the basic concept which describes the behavior of an emulsifier. It can be modified by choosing the correct lipophylic backbone (e.g.: fatty acid , castor oil, fatty alcohol) and hydrophilic head (EO, EO/PO, Phosphate esters etc). Lamberti presents one of the widest portfolio of emulsifiers tailored for the different market sectors applications. DETERGENTS: for Textile, Leather, I&I In the common sense detergency means the removal of water insoluble particles from a substrate (a fabric, skin, hard surface etc). A detergent can be represented as a molecule with two moieties: a lipophilic which adsorbs onto the oil and fat droplets and an hydrophilic which brings the fats into the water. Classic Anionic (sulf(on)ated, sulfosuccinates) and non-ionic surfactants like branched fatty alcohol ethoxylates (e.g. Rolfor TR8/L) or innovative green products like Esters of Alkyl-poly-glucosides (Eucarol AG-EC), are typical detergents present in our range. WETTING AGENTS: Textile, Agrochemicals, Cosmetics, Leather, Building When a water solution is spread over an hydrophobic surface or particle, it can be necessary to shorten the time by which the surface or particle get wet. The process is helped by addition of wetting agents. Typical wetting are Anionic surfactants (sulf(on)ates, sulfossucinates ) and non-ionic like (C8-13) alcohol ethoxylates. Again the correct choice depends on HLB and on the structure of the products. DISPERSING AGENTS: Agrochemicals, Drilling and Mining, Pigments, Ceramics Dispersion is a heterogeneous system where a solid (e.g. a pigment) or an oil droplet (like a pesticides) is suspended into water (or http://www.lamberti.com/technologies/oleochemicals.cfm 10/29/2008

Page 2 of 2 Dispersion is a heterogeneous system where a solid (e.g. a pigment) or an oil droplet (like a pesticides) is suspended into water (or oil/solvent) The system is naturally unstable: to avoid syneresis, precipitation, caking or re-crystallization we have to use special molecules that generally have an hydrophobic tail with strong affinity to the dispersed particles - so as to get adsorbed (reversibly or un- reversibly) onto the solid particles surface - and an hydrophilic head (ionic or nonionic) with strong affinity to the water. Electrostatic and/or steric repulsions avoid precipitation and re-crystallization. Lamberti has a wide range of Dispersing Agents: from classic non-ionic (e.g.: EO/PO copolymers, amine or tristyrylphenol alkoxylates) or anionic (e.g.: phosphate and sulfate esters of macromolecular backbones) up to novel POLYMERIC SURFACTANTS. DEFOAMERS: Pulp & Paper, Coatings, Tailored polysiloxane formulations and special non-ionic adducts can be use to avoid foam's formation during the different manufacturing and application processes. In Coatings and Papers massive quantities of antifoaming agents are applied but quite all industrial processes need them. ADJUVANTS: Agrochemicals Improving biological performance of a pesticide is a becoming more and more important in Crop Protection to reduce concentration of poisoning materials, improve handling and safety of operators and consumers. Adjuvant can work as a real co-active ingredient when it shows a synergic effect with the pesticide, or can help penetration into leaf or soil (wetter) , or improve rain fastness (spreader and sticker) by prolonging the activity of the pesticides, or simply avoid drift during the spray (antidrift). Lamberti can provide a wide portfolio of adjuvants designed for the most selective applications: combinations of surfactants in form of emulsions and micro emulsions (e.g.: patented MICROBIO) or quot;green productsquot; like patented EUCAROL AGEs are some of our products. http://www.lamberti.com/technologies/oleochemicals.cfm 10/29/2008
