During the first half of 2025, DSBP prices showed a steady to slightly bullish trend across major regions. The price movement was influenced by raw material dynamics, particularly the supply and cost trends of formaldehyde and other aromatic intermediates. In Asia, stable demand from the textile and paper industries supported prices, while fluctuations in China’s formaldehyde supply around the Lunar New Year had a mild impact on overall production costs. India's consistent construction and resin activity also indirectly influenced DSBP markets through stable formaldehyde inputs.
In Europe, the upward momentum in DSBP pricing was more pronounced due to tight raw material supply and rising energy costs. Disruptions in methanol and formaldehyde availability early in the year led to cost pressures, which producers passed down the chain. North America followed a similar pattern, where supply issues and plant outages pushed input costs higher, keeping DSBP prices elevated despite mixed demand signals from construction and industrial coatings sectors.

Throughout 2024, DSBP prices showed considerable volatility across global markets. In Asia, prices followed a downward trajectory during most of the year, with temporary stabilization in Q2. The market faced pressure from weak demand in key sectors like electronics and optical brighteners, coupled with sufficient supply levels from major producers. Domestic manufacturing slowdowns in China and India further suppressed procurement enthusiasm.
European markets witnessed similar declining trends, though less pronounced than in Asia. The market struggled with reduced downstream demand, particularly from construction and automotive sectors. Production costs remained elevated due to ongoing energy concerns, but oversupply conditions prevented price increases, leading to squeezed margins for producers.
North American DSBP market started strong but gradually declined throughout the year. Price volatility increased during Q3, primarily due to hurricane season disruptions affecting supply chains and production facilities. Despite these temporary shutdowns, overall demand remained sluggish, preventing any sustained price recovery. Regional manufacturers adjusted production rates to match the tepid demand, especially as imports from Asia offered competitive pricing.
DSBP, popularly known as Tinopal CBS-X, appears as a greenish yellow solid. It is used as an optical brightening agent for home care applications. It provides excellent white effects on cellulosic fibres over the whole temperature range, particularly from cold to medium working temperatures. It has a higher yield of whiteness than the traditional stilbene type brighteners. It finds wide applications in paper and pulp industry.

In this process, 4,4- bis(chloromethyl) biphenyl, obtained from the reaction between biphenyl and formaldehyde, is utilised to produce DSBP. 4,4- bis(chloromethyl) biphenyl is heated at a temperature between 117 and 119oC in the presence of trimethyl phosphite to give 4,4- bis(dimethoxyphosphonomethyl)biphenyl and methyl chloride, which finally reacts with benzaldehyde sulphonic acid to form DSBP.
