Import Bentonite Activated Bleaching Clay — Buy in Bulk from Supplier in China

Dongying Fuze Imp. & Exp.Co., Ltd. supplies activated bleaching clay produced through acid activation of bentonite with concentrated sulfuric acid, yielding a sub-white powder described as odourless and effective for bleaching and purification. The supplier's office is located in Dongying, Shandong Province, a region with established petrochemical infrastructure that supports acid-activated clay production for edible oil refining and industrial applications. The product targets manufacturers in food and beverage, petrochemicals, cosmetics, and pharmaceutical sectors where adsorptive decolourisation of oils and fats is required.

Acid-activated bleaching clay differs from natural bentonite through controlled treatment with mineral acids, which leaches octahedral cations (typically aluminium, iron, magnesium) from the montmorillonite structure, increasing surface area and developing Brunsted acidity. This modification typically raises specific surface area from 50-100 m²/g (natural bentonite) to 150-300 m²/g, with pore volume concentrating in the 2-10 nm range optimal for adsorbing chlorophyll, carotenoids, and oxidation products from triglyceride matrices. The sub-white colour indicates low residual iron content, a critical parameter for edible oil applications where catalyst metals promote rancidity. Typical free acidity (as H2SO4) ranges from 0.1-0.3% for refined grades, though buyers should confirm this with the supplier.

Primary buyers include vegetable oil refineries processing palm, soybean, sunflower, and rapeseed oils; petrochemical operations purifying lubricant base stocks; and manufacturers of oleochemicals. The supplier indicates flexible minimum order quantities without stating specific thresholds, and references ISO and SGM certifications without providing certificate numbers or scopes. Shandong Province offers export advantages through Qingdao and Tianjin ports, with established freight networks to Southeast Asian edible oil hubs and European oleochemical processors. Buyers should request activation-specific parameters including specific surface area (BET method), free acidity, moisture, and decolourising efficiency on a standard oil substrate before finalising supply agreements.

Dongying Fuze Imp. & Exp.Co., Ltd. operates from 707-9 North 2nd Road, Dongying, Shandong 257061, China, placing it within a province with substantial petrochemical and clay processing infrastructure. The supplier holds an 'imported' tier designation alongside a 'harbor' trust tier, suggesting it engages in international trade though the exact nature of its production versus trading activities is unspecified. Like the previous listing, its response rate is 0.00% with zero recorded average response hours, indicating no demonstrated responsiveness through platform channels.

The company profile does not disclose establishment date, production capacity, number of employees, annual revenue, or specific processing equipment. No client references, audited quality management system certificates, or detailed manufacturing flow diagrams are provided. The listing mentions ISO and SGM certifications without certificate numbers, scopes, or accreditation bodies, which buyers must independently verify. The supplier's description positions it as offering 'flexible MOQ options' and 'competitive pricing' without quantifying either parameter.
