Research activities


a. Development of standards and methods for testing of raw materials used by the company and for the finished products manufactured.

b. Development of new products based on the requirement of the market. The activity involves developing standards for ingredients, Formulation including excipients, SOP including process parameters, in-process quality checks, standards for the finished product, stability and shelf life etc.

c. Process improvement has been undertaken for the processing of ‘Asawarishtas’, one of the major category of the products to reduce the processing time and at the same time achieve better batch to batch consistency. Processing of ‘Guggul Kalpas’ has also been streamlined to achieve more homogenous product simultaneously saving substantial quantity of fuel. Modern technology has been adapted in the process of ‘Bhavanavidhi’ to reduce process time. It may be mentioned that these improvements have been implemented on production scale without compromising the basic tenets of Ayurvedic processing.

d. Safety evaluation of selected products by conducting acute and chronic toxicity studies has been undertaken.

Setting of standards for Raw materials

The R & D department, after extensively studying several lots of various raw materials, has established our own in-house standards for more than 200 raw materials required for SDL products. These standards are used to monitor the quality of raw materials on a day-to-day basis. They are regularly updated to keep in tune with scientific progress.

Setting of standards for Finished Products

The company has 191 products on its pricelist and has established standards for all the products. The standards have been laid down after studying and analyzing more than 20 batches of every product. Chromatographic fingerprinting, quantification of active substances and of markers, quantitative estimation of elements in metallic preparations by Atomic Absorption Spectroscopy are some of the techniques employed for the purpose.

 Evaluation of Safety

Rasuashadhis are one of the main products of our company. These are metal based products used extensively in Ayurvedic therapeutics. Due to presence of metals there is a general concern for safety. As a precautionary measure SDL carries out acute toxicity study according to OECD guideline on random batches of all metal based products to ensure that they are safe for use. These studies are carried out in company’s own animal house.
