Water Solutions & Specialty Chemicals (WSSC)

Chemtrade’s WSSC business segment operates an extensive North American plant network, producing both traditional industrial chemicals and customized solutions for our customers. The Water Solutions segment consists primarily of inorganic salts, used as coagulants by municipal and industrial customers to treat water and wastewater. Additionally, the Water Solutions team produces a group of products used by poultry growers, as litter amendments, to control ammonia volatilization and improve bird health and productivity.

Along with coagulants and poultry litter amendments, WSSC produces Specialty Chemicals used in a wide range of industries including the paint (ink, pigment, etc.), oil & gas, pharmaceutical, nutraceutical, food & beverage, and tantalum refining industries.

Vaccine Adjuvants

Vaccine Adjuvants (Aluminum Adjuvants)

Chemtrade offers an extensive line of aluminum-based Vaccine Adjuvants. They are highly versatile and meet a broad range of pH, protein binding, and other vaccine requirements. In addition to our standard grades, Chemtrade can customize its Vaccine Adjuvants to meet the needs of specific vaccines. Our products are manufactured at our current Good Manufacturing Practices (cGMP) compliant, ICH-Q7 regulated facility in Berkeley Heights, New Jersey.

REHYDRAGEL™ adsorbent aluminum hydroxide gels have been used for many years as adjuvants in veterinary vaccines, and in the human biological field as both a vaccine adjuvant and a blood protein separation aid. These highly purified aluminum hydroxide gels also provide maximum protein adsorption when used as matrices or carriers for veterinary antitoxins.

Standard Products

  • REHYDRAGEL™ LV – Rehydragel™ LV is a highly active protein adsorbent specially compounded for use as a fluid adjuvant. It has low oxide content and is carefully controlled for Al2O3 content and protein binding capacity. It has a lower viscosity than competing adjuvants, which makes it easier to process and handle.
  • REHYDRAGEL™ HPA – Rehydragel™ HPA is manufactured by special techniques to provide maximum protein binding and point of zero charge at pH 12. It is a sterile, low-oxide, thixotropic gel containing sub-micron particles that can boost protein adsorption compared to conventional adjuvants.
  • REHYDRAGEL™ CG – Rehydragel™ CG is a non-sterilized gel often diluted to form suspensions with relatively low Al2O3 concentrations and is used in veterinary vaccines that need high adjuvant levels. It is highly gelatinous, nearly translucent, and non-reactive.
  • REHYDRAPHOS™ – Rehydraphos™ is an amorphous aluminum hydroxyphosphate having an acidic isoelectric point. This property, combined with its high surface area, gives it a high adsorptive capacity for basic or positively charged antigens. The Al:P ratio is 1:1.

In addition to the grades listed above, Chemtrade offers customized adjuvants to meet the needs of specific vaccines.
