  1. 1. TRENDS IN SURFACTANT SCIENCE : OPPORTUNITIES & CHALLENGES SHRIRAM INSTITUTE FOR INDUSTRIAL RESEARCH, 19 UNIVERSITY ROAD,NEW DELHI-110007 PRESENTED BY : DR. R. K. KHANDAL
  2. 2. Systems Surfactant Science : Challenges & Opportunities Description Remarks Phases Gas / Liquid/Solid Resist any changes Surfaces Liquid Liquid : Emulsion Solid Liquid : Dispersion Liquid Gas : Fog Gas Liquid : Foam Solid Gas : Dust Liquid Solid Gas : Complex Surfaces in equilibrium with Gas phase (Air) Interfaces Stabilisation/ Destabilisation Surfactants play a key role by modifying the surfaces (interfaces) Tension Homogenity/ Micronisation Surfactant can separate or mix different surfaces Affinity Surfactants help solublize substrates into matrices Gas/Liquid; Gas Solid Multi phase and Multi facialProduct Surfactants are enablers as well as stabilizers  Surfactant science deals with surfaces rather than with the bulk and that is the challenge !
  3. 3. Surfactant Science : Challenges & Opportunities Kinetically stable Thermodynamically unstable Surfactants can only create barriers which prevent destabilization for a fixed time Multi phase, Multi - face product Challenge Opportunity Thermodynamic Stability Surfactants bringing in ultra low interfacial tension effect  The aim to have thermodynamic stability is so challenging that opportunities are enormous
  4. 4. Natural multiphase multi- facial systems Artificial multiphase multi-facial systems  Crude Oil  Dust  Fog  Foam  Challenge : A simple surfactant to deal with complex and diverse systems  Opportunity : Enormous for the life support systems  Emulsion  Cream  Dispersion  Foam Role of Surfactants  Dehomogenise  Destabilise  Separate the discontinuous phase from the continuous phase  Homogenise  Stabilise  Convert discontinuous phase into the continuous one by merging it into the continuous matrix Surfactant Science : Complex Systems
  5. 5. Support Systems Surfactant Science: Life Support Systems Requirements Challenges Opportunities Agriculture  Soil  Agrochemicals More from less More effect less residues  Modify soil surfaces  Maximum agrochemicals in small volume  Homogenise non- polar chemicals with water  Non-arable to arable  Safe crops  More yield Health  Target drug delivery  Penetration into the body systems  Compatibili- sation of drug formulations to body systems  Reduction of interfacial tension  Solubilisation of nonpolar drugs in water  Efficacy of drug formulations  Safe health care products  Benefits to common people Transport  High speed transport  Aerodynamics  Fuel efficient  Non - Toxic emissions  Lubricating systems  Brake fluids  Self cleaning engines  Efficient injection systems  Energy saving  Improved life style
  6. 6. Support Systems Surfactant Science: Life Support Systems Requirements Challenges Opportunities Shelter  Weather-proof housing  Light weight construction  Improved mix designs  Weather proof coatings  Modified concrete surfaces  Self curing with little water  Societal growth  Economic growth Materials  Bio-compatible  Biodegradable  Long life  Recyclable  Modify surfaces  Improved processibility  Enhanced weather-proofness  Enormous textiles, Fibers, polymers, metals alloy, composites  Surfactants play a pivotal role in meeting the requirements while converting challenges into opportunities
  7. 7. New Materials Modifications Improved Designs Product Device Surfactants drive the cycle forward always providing modifications of surfaces  Each time a new device results in a product, the need for modifications leading to the requirement of new materials arises.  Surfactants provide the modifications necessary for improving performance of materials Surfactant Science : Development Cycle
  8. 8. Surfactants market: Region-wise split  Challenge: Affordable surfactants  Opportunity: A huge market potential 35% 29% 23% 13% Rest US Europe Asia Pacific 70% of surfactants consumed by 30% of population
  9. 9.  Most of is going in to cleaning  Challenge lies in exploiting it for industrial problems which present as opportunity for market growth Global surfactant market by end-user application Household Detergents 40% Textile Auxiliaries 10% Personal Care 9% Industrial and Institutional Cleaning 6% Oilfield 5% Others 30% GLOBAL SURFACTANTS MARKET: END-USER-WISE

  11. 11. Surfactant Market: Consumption and Potential Country Per Capita Consumption US 4.0 Europe 3.5 Japan 3.8 China 0.7 Others < 0.3.5  Challenge: Convert potential into actual  Opportunity: Huge Potential
  12. 12. Surfactant Science: Challenges and Opportunities New material Raw Material Alternate to New Surface Renewable Petro Hydrophobes Resources Process Green New Scales Bio-Route Technology Cost -Effective Environment Biodegradability Stringent Surfactants Concerns Toxicity norms derived from renewable resources Applications Micro-scale Enormous to sub-micro scale  Potential is high but remains hidden !  A relook in the approach is necessary !
  13. 13. Surfactant Science: Path Forward Develop  Raw materials from renewable resources  Process using enzymatic and other bio-routes  Specialty Synergistic products to produce nano materials  Surfactants have always been a preferred subject of research and it will continue to remain so in future with perhaps complete shift in approach and emphasis
