From nature to innovation: The rise of biobased surfactants
Vishal Sharma, CEO of Godrej Industries, overviews why biosurfactants are the future
Surfactants sit quietly behind most routines, making soaps lather, shampoos spread evenly and detergents lift away stains. They are also built into industries that most consumers take for granted: textiles, pharmaceuticals, food processing, even agriculture.
Their function is simple: to lower surface tension so that water can interact with oils and dirt. That simplicity, combined with their versatility, has made them indispensable but it is also why the industry behind them is under growing pressure to change.
For the better part of a century, surfactants were built on petrochemicals. They were reliable, cheap, and easy to scale, making them perfect for the mass-market boom of the 20th century. What got ignored back then is impossible to ignore now, however. Synthetic surfactants are tied to fossil fuels, many do not break down easily and they linger in water systems long after use.
Regulators are catching up and so are consumers who care about what is in their daily products.
The result is a hard push toward biobased surfactants— renewable alternatives drawn from vegetable oils, sugars or microbial fermentation. These new options promise faster biodegradability, lower toxicity and a closer fit with global climate goals.
From synthetic dominance to biobased momentum
The reasons synthetics dominated were obvious: they worked, and they were cheap. Entire industries grew around that predictability. But reliance on fossil feedstocks and the environmental persistence of these chemicals has left the sector exposed. The ecological cost is clearer with each passing year.
Biobased surfactants are the counterpoint. They tap renewable inputs such as agricultural by-products and leverage microbial fermentation to create compounds like sophorolipids and rhamnolipids. In some cases, they can match or even beat synthetics in performance.
Consumer trends are adding fuel.‘ Clean beauty’ claims, eco-labels, and the steady rise of sustainable cleaning products have made adoption less a choice and more an expectation. What was once a niche is fast moving into the mainstream.
The balancing act: Performance, cost, scale
Even so, the transition is complicated. Synthetic surfactants have had decades of process fine-tuning. That is what makes them so cheap and consistent. Biobased versions do not yet have this. Yields can be low, costs higher and production less predictable. For companies, the challenge is to deliver sustainability without asking consumers to pay a premium that feels unreasonable.
Research is where the heavy lifting happens. Advances in fermentation technology and metabolic engineering are steadily improving output and reducing variability. Biosurfactants are being tested under demanding industrial conditions to prove they can perform without losing biodegradability.
Meanwhile, regulators are beginning to provide clearer standards around toxicity, safety and biodegradability. That helps build confidence across the value chain. The OECD’ s work on guidelines for biosurfactants is just one example.
Where consumers feel it first
The most visible applications are in personal care and home care— products that people use daily and are quick to judge. Here, biobased surfactants have a clear edge. They are milder, less irritating and safer for sensitive uses like baby shampoos, face washes and cosmetics. In cleaning products, their
