About Clean Science and Technology
Clean Science and Technology Limited makes fine and specialty chemicals. It sells to the performance chemicals, pharmaceuticals, agrochemicals and FMCG sectors, and has customers across more than 35 countries.
Its product portfolio is organised into three segments: Performance Chemicals, Pharma-Agro and FMCG. Performance Chemicals includes antioxidants such as BHA and TBHQ, and the HALS series of polymer stabilisers. The Pharma and Agro Intermediates segment addresses specialised applications across pharmaceutical formulations, agrochemicals and flavour and fragrance industries. The FMCG Chemicals segment serves personal care, cosmetics and consumer-focused chemical applications.
The company operates four manufacturing facilities in Kurkumbh, Maharashtra, and all of its manufacturing facilities are certified under international quality, environment and safety standards. It commissioned a hydroquinone and catechol plant in December 2025. At least 64 scientists work in its research and development facilities, which are supported by an application laboratory for HALS. A dedicated pilot facility supports its operations, and all sites follow a Zero Liquid Discharge framework, which means no industrial wastewater is released.
It was incorporated in 2003. It has commercialised anisole manufacturing, among other products. Its wholly owned subsidiary Clean Fino-Chem Limited carries the expansion of the HALS business. At the end of the year to March 2026, the company had four wholly owned subsidiaries in all: Clean Fino-Chem Limited, Clean Science Private Limited, Clean Organics Private Limited and Clean Aromatics Private Limited.
