Calcium salicylate

Calcium salicylate (CAS 824-35-1) is the calcium salt of salicylic acid, commercially known under trade names including Cyl-Re, Salikalz, Helioscin, and SAP 002. It carries no assigned E-code and is categorised within the salts and minerals class. Its molecular formula is C7H6O3.1/2Ca.

In pharmaceutical formulations, calcium salicylate functions as a pH buffer, stabilising active ingredient environments through controlled acid-base equilibria. In personal care products, it acts as a preservative by disrupting microbial cell membranes at low concentrations, extending product shelf life without reliance on conventional paraben-based systems.

Calcium salicylate is available in solid form and may be sourced to pharmaceutical-grade specifications aligned with Ph.Eur. monograph requirements. Procurement should confirm REACH compliance documentation from the supplying entity. Standard packaging formats vary by supplier; technical datasheets should be requested to verify grade suitability for the intended application.
