Technology Development for Soap, Detergent and its Raw Material Testing (Part-I A: Portable Kit used for Quality Control of Soap & Detergent)

In rural areas, Khadi and Village Industries (KVI) units and small-scale handmade soap manufacturers commonly utilize raw materials such as oils, fatty acid distillate, acid slurry, caustic lye, sodium silicate, and soda ash for the production of soaps and detergents. To uphold product standards and customer confidence, it is crucial to guarantee the quality and uniformity of both raw materials and completed goods. However, the lack of affordable, accessible, and user-friendly testing facilities often leads to quality control issues. In response to this need, a practical and cost-effective "Testing Kit for Soap, Detergent and its Raw Materials" was developed during the 2008–09 study. This kit was designed to support KVI units and grassroots producers by enabling in-house quality assessment of raw materials and finished goods. The kit includes simplified analytical methods suitable for field-level application without requiring sophisticated laboratory infrastructure. This paper presents the development of a low-cost, user-friendly testing kit for evaluating quality parameters of soap, detergent, and raw materials, intended for application in Khadi and Village Industries (KVI) sectors and small-scale manufacturers. The design of the kit is simplified for non-laboratory rural settings and is based on standardised test protocols described by the Bureau of Indian Standards (BIS) [1]– [5].
