Explore our primary formulations engineered for cosmetic antiperspirants, industrial decolorization, and municipal water purification.
Aluminum Chlorohydrate (ACH) stands as the most critical active ingredient in the global personal care market, particularly in anti-perspirant and deodorant formulations. Chemically represented as $Al_2(OH)_5Cl$, ACH has dominated the industry due to its superior efficacy in temporary sweat duct occlusion. Because of its high basicity (typically between 82% and 84%) and elevated $Al_2O_3$ content, ACH exhibits an exceptionally high polymeric structure. This allows cosmetic and pharmaceutical formulators to achieve superior sweat reduction performance with significantly lower concentration thresholds compared to conventional aluminum salts.
Beyond cosmetics, the commercial demand for high-basicity ACH has surged in high-tech municipal water purification, paper manufacturing, and membrane process pretreatments. As global regulations like the European Commission's SCCS (Scientific Committee on Consumer Safety) and the US FDA tighten heavy metal restrictions (specifically for Arsenic, Lead, and Mercury), sourcing ACH from suppliers capable of manufacturing high-purity, low-impurity batches is paramount for global brands.
In Wuxi, China, Wuxi BS Water Treatment Chemicals Co., Ltd. has pioneered the advanced synthesis of high-basicity ACH. By utilizing state-of-the-art reactor arrays and high-purity aluminum ingots under precise thermal control, we produce ACH that meets both standard water purification requirements and strict cosmetic-grade limits.
Discover the chemical complexity behind high-basicity Aluminum Chlorohydrate synthesis and how our research team pushes the boundaries of molecular stabilization.
Our research focuses on maximizing the concentration of the $Al_{13}$ and $Al_{30}$ polycations. These specific structural states of aluminum provide the optimal charge density for coagulating organic colloids and generating micro-gel barriers in cosmetic antiperspirants.
Traditional industrial-grade aluminum salts carry iron levels that cause yellow staining in textile applications and cosmetics. Our technological roadmap guarantees ultra-low iron content (< 0.005%) and heavy metal counts far exceeding global regulatory requirements.
By controlling the reaction kinetics of hydro-soluble aluminum salts, we stabilize basicity levels to 83% average. This ensures optimal pH buffering, reduced skin irritation potential, and high formulation compatibility with cosmetic emulsions.

The fundamental differences lie in the basicity and alumina content. Standard PAC typically exhibits a basicity between 50% and 65%, with an $Al_2O_3$ content of 10% to 30%. Aluminum Chlorohydrate (ACH) is the highest concentrated polymer in the PAC family, with basicity levels ranging from 82% to 84% and $Al_2O_3$ concentrations reaching 23% in liquid formulations and 46% in powder formulations. Additionally, ACH is characterized by a significantly higher concentration of $Al_{13}$ and $Al_{30}$ polymeric isomers, which enables more efficient coagulation and gel formation with fewer free chloride ions, reducing corrosiveness and dermal irritation.
When applied to the skin, the relatively high pH of sweat (dermal fluid) causes the highly basic ACH polymer to undergo rapid hydrolysis. This chemical reaction forms an amorphous aluminum hydroxide micro-gel plug inside the outer portion of the eccrine sweat gland duct. This temporary barrier physically prevents sweat flow from reaching the surface of the skin. Over time, skin desquamation and the natural outward flow of sweat break up and flush out the plug, ensuring that the sweat gland duct is not permanently obstructed.
Our production lines feature digitized, closed-loop process automation where precise quantities of raw high-purity aluminum and hydrochloric acid are reacted under constant temperature and pressure. Every production run undergoes rigorous ICP-MS and chromatography checks in our specialized QC laboratory. This process ensures that heavy metals such as Lead (Pb), Arsenic (As), and Mercury (Hg) remain strictly within cosmetic and food-grade limits (typically <10ppm overall), and iron impurities are kept below 50ppm to prevent fabric discoloration and maximize product clarity.
Both the US Food and Drug Administration (FDA) and the European Scientific Committee on Consumer Safety (SCCS) recognize Aluminum Chlorohydrate as safe and effective for over-the-counter (OTC) antiperspirant applications. The FDA Monograph permits the use of ACH at concentrations up to 25% on an anhydrous basis in roll-ons, aerosols, and creams. The EU SCCS, in its recent evaluations, has concluded that the topical application of aluminum compounds does not pose a systemic health risk, as transdermal absorption is extremely low (around 0.012%), declaring it safe for cosmetic application.
Yes. Wuxi BS has been exporting high-performance water treatment polymers and cosmetic ingredients globally since 2007. We regularly package and ship liquid ACH in 1000L IBC Totes, 200L drums, or custom Flexitanks for major international chemical distributors. Our location near key ports (Shanghai/Ningbo) minimizes transit delays, and our finished product warehouse, maintaining over 20,000 tons of stock, ensures continuous supply chains even during high-demand seasons.
