The export market prices of Diphenhydramine Hydrochloride in China have increased in December 2025. The increase in the market value of Diphenhydramine Hydrochloride has followed a significant decline which was observed in previous month, November of 2025. The shift in the Diphenhydramine Hydrochloride prices was observed by the domestic and international buyers as the market has shifted from cautious procurement to more active purchases. The decline in November was the result of limited purchases of the buyers which resulted in the lean inventory position across several of the downstream segments. The buyers have reassessed their stock levels in December for upcoming production schedule of early 2026. The shift in buying sentiment with the strategic response from suppliers have created a renewed increase in the market. The improvement in demand was not abrupt and has reflected calculated inventory management to align it with the downstream production. ChemAnalyst anticipates that the prices of Diphenhydramine Hydrochloride will likely decrease in January of 2026.
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.
