As the formulators of products for different markets and end user applications, we are used to work with micron sized particles, powders and materials. A nano particle is 1000th the size of a micro material (1nm = 1 x 10-9 metre). By decreasing the particle size we are increasing the surface area and the surface availability of atoms, thereby increasing activity per unit mass.
But, the activity per unit surface area for nano particles can be greater than for the micron sized material. This observation means that by decreasing particle size from an array of atoms (micro) towards a cluster of atoms (nano) it may be possible to create a nano raw material with the same chemical formula but enhanced chemical properties representing a technological paradigm shift.
Apart from the chemical interactions determined by the electron properties of nano materials, the physical effects on a formulated system of introducing nano particles should also be considered. For example, introducing billions of tiny nano nuclei into a polymer or resin is likely to induce crystallisation and order to a film in place of disorder. Try combining these physical effects with enhanced or unexpected chemical reactivity.
In liquid systems for personal care, preservative–free and translucent nano-emulsions provide effective means to solve the solubility problems associated with conventional micro-emulsions with a cleaner system that can improve the delivery of active molecules onto the surface of the skin.
You can be sure you have a nano effect when the observed performance of your formulation cannot be extrapolated from the performance expected of the bulk raw material. When the observed performance is unexpected perhaps you have created a technological paradigm shift leading to improved performance, lower cost and enhanced profitability.
The formulator working within the commercial constraints of a competitive market will always have to estimate the value of the nano material in terms of formulation cost versus in place performance. Significant changes to the in place properties of commercial products have been observed after adding as little as 0.01% of a nano component. Other systems require 1% to 30% levels of nano materials and exciting new products can be created by using 100% nano raw materials.
