Alcohol based emulsifiers for Emulsifiable Concentrates ”Matched pair” system Key benefits
The total concentration of the emulsifier
blend is normally 5-10% of the formulation.
The optimum ratio of anionic and non-ionic
with regards to spontaneous emulsification
in water and the stability of the emulsion inrequired temperature and water hardness. All recipes optimised in accordance with
usually works better than single compo-nents and make it easier for the formulator.
HLB value is a theoretically calculatedvalue of the hydrophobic (solubility in oils)
and hydrophilic (solubility in water) balanceof a surfactant. The system was introducedin the 1940's and does not cover the newertypes of surfactants. Water hardness The formulation suggestions are optimised
for 500 ppm CaCO3 and if a better stabilityis required in soft water, the emulsifier
system has to be adjusted to a more hydro-

Beyond resources ACHIEVING universal elementary education is not merely a function of availability of additional resources or even an expansion of the school infrastructure. These are necessary but insufficient conditions for making universal elementary education a reality. After the launch of the Sarva Shiksha Abhiyan (SSA), the debate on the Right to Education has focused, I believe erroneou
