Clarifying the Term "Calcium Sucrose Phosphate"
The term “calcium sucrose phosphate” has been used in scientific and patent literature for more than a century and may refer to different materials.
Early European patents described calcium sucrose phosphate as a chemical compound produced by reacting sucrose, phosphate and calcium-containing reagents. By contrast, Anticay®, developed by CSR and researchers at the University of Melbourne during the 1960s, was described as a more complex system containing calcium sucrose phosphate species together with inorganic calcium phosphates.
This distinction is important because not every historical reference to “calcium sucrose phosphate” necessarily refers to the Anticay® technology investigated in the original Australian research programme.
On this site, references to “calcium sucrose phosphate”, “calcium sucrose phosphates” or “CaSP” generally relate to Anticay®, New Anticay® or related calcium sucrose phosphate technologies, unless otherwise noted.
Understanding the Science Behind Anticay®
For more than sixty years, researchers have investigated the role of calcium sucrose phosphate technologies in oral health.
The studies collected within this library represent a body of work spanning laboratory investigations, animal studies, clinical trials and modern remineralisation research.
Together, these publications help document the scientific foundations of Anticay® and the continuing evolution of calcium sucrose phosphates (CaSP) technologies.
HISTORICAL ANTICAY RESEARCH (1960–1976)
The original Anticay® research programme was conducted by researchers at Melbourne University, CSR Limited and collaborating institutions during the 1960s and 1970s.
This work established many of the scientific foundations that continue to influence modern calcium-phosphate research.

Mechanism of Action
Anticay® calcium sucrose phosphates were developed to help provide calcium and phosphate in a highly soluble, available form.
Historical research suggests that these ions may interact with the enamel surface, support normal remineralisation processes and help reduce mineral loss during acidic challenge.
This section brings together key studies and documents explaining how Anticay® was understood to work.
The proposed mechanism of Anticay® was based on three related effects:
- increasing the availability of calcium and phosphate ions in the oral environment
- supporting natural remineralisation processes when enamel mineral has been lost
- helping reduce the rate of mineral dissolution during acid challenge
This mechanism was described as complementary to fluoride.
This CSR-produced historical technical summary describes the proposed mechanisms by which Anticay® may influence enamel mineral balance.
Topics include:
- calcium and phosphate ion availability
- enamel dissolution kinetics
- remineralisation processes
- adsorption of sucrose phosphate species
- complementary action alongside fluoride
