The prices of Diphenhydramine Hydrochloride have tilted upward across the Asia-Pacific region in October 2025. The increase in market value was driven by a confluence of seasonal demand, active domestic buying and strategic pricing by the supplier. The end-user offtake for OTC antihistamine formulations in India was firm which was a result of seasonal shifts and downstream demand from consumer healthcare channels. The increased demand of Diphenhydramine Hydrochloride in the Indian domestic market of the antihistamine OTC formulations has encouraged the manufacturers to run strong production cycles. The suppliers have lifted the offers and leveraged firm offtake to protect their profit margins and support higher spot levels. The export market of Diphenhydramine Hydrochloride in China also moved in upward direction but marginally. The steady international and local procurement has maintained a gentle upward trajectory without triggering panic restocking. The inventory covers were adequate and buyers have adopted measured purchasing. The upstream production capability, downstream seasonal demand and supplier pricing strategy has pushed the spot prices higher across key APAC hubs.
Selenis has effectively manufactured recycled PET chips using terephthalic acid sourced from Circ®, a textile-to-textile recycler based in Virginia. The chip production took place through a series of batches at Selenis' pilot plant in San-Giorgio, Italy. By utilizing inputs recovered from polycotton textile waste, Selenis has created high-quality PET chip, which has been further processed into DTY yarn. This yarn will play a crucial role in product development as Circ prepares for additional capsule launches. Selenis is leveraging the success of this initial collaboration phase and is committed to advancing towards an offtake partnership to support Circ's inaugural industrial facility.
Eduardo Santos, Head of Corporate Strategy at Selenis, remarked that the monomer synthesis showed a performance comparable to virgin terephthalic acid. He expressed optimism about the consistent quality of Circ's monomer output and anticipated future commercial success. Santos pointed out that the Circ partnership complements Selenis's existing mission and goals for a more sustainable textile industry. He further stated their anticipation of expanding upon this collaboration and providing support for Circ's forthcoming commercial production trials.
