Material Science Division is actively involved in the area of herbs with medicinal value and economic benefit.
The R&D areas include:
- Formulation development
- New product development
Major R&D Projects:
- Retention of color fastness in henna cones on storage
- Phytoremediation of arsenic in ground water
- Extraction process for hypericin from hypericum plant
Several projects related to the quality evaluation of herbal products are being actively pursued by the Drug and Pharmaceutical section of Biology Division of SRI.
In view of the excessive utilization and continuous depletion of petroleum reserves, SRI is involved in the development of products based on renewable natural resources as substitute of petroleum derived products. These include:
- Organic active extraction
- Eco-friendly composites
- Bio- degradable fibers/ polymers
- Natural mordants for dyeing with natural dyes
Major R&D Projects
Some of the projects based on renewable sources undertaken by SRI include:
- Anti-oxidants from natural source
SRI has successfully isolated natural antioxidant gum guaiac from Guaiacum officianale plant. Antioxidant effectiveness of isolated gum guaiac in fats/oils was found comparable with commercial antioxidant.
- Epoxidised oil from plant seeds Epoxidised oil was extracted from seeds of Vernonia plant. This naturally epoxidised oil can be used as plasticizer/stabilizer in PVC based compositions replacing synthetically produced epoxidised soyabean oil.
- Cardanol from cashew nut shell liquid
A distillation process has been developed to recover 90% cardanol, which is light in color and does not darken upto one month.
