Nirma was a government chemist's backyard detergent — it became a national brand

In 1969, Karsanbhai Patel was a laboratory technician at the Gujarat Government's Department of Mining and Geology. He was a government chemist, not a businessman. He created a low-cost synthetic detergent powder at home because he thought the existing brands — like HUL's Surf at ₹13 per kilogram — were too expensive.

Patel manufactured the detergent in a small room at his house in Ahmedabad. He named it 'Nirma' after his daughter Nirupama. Each morning, he packed 15 to 20 packets and cycled about 15 km to his government office, selling the packets along the way. The product was never intended for mass production — it was a one-man operation.

The detergent was popular because it was affordable. Patel's product cost ₹3.50 per kilogram, while competing brands cost more than three times that. The detergent was phosphate-free and effective. By 1985, Nirma had become a household name across India, famous for a television jingle that every Indian child knew.

The business grew organically. Patel never planned to build a detergent company. He was a government chemist who made detergent for himself. By the 2000s, Nirma had grown from detergent into soaps, shampoo, and other household products. A chemist's backyard operation became a national consumer goods brand.
