Executive Summary
Calcium gluconate is a water-soluble organic calcium salt of gluconic acid. Gluconate salts are oxidation products of glucose and occur widely in nature. Calcium gluconate belongs to the hydroxycarboxylic acid salt family. The chemical structure of calcium gluconate consists of a sixcarbon chain with five hydroxyl (-OH) groups terminating in a carboxylic acid group. Additionally, the salt is composed of one calcium ion (Ca2+) for every two gluconate anions (C6H11O7-). The close proximity of the oxygen atoms within the chemical structure lends to its function as a highly efficient chelating agent. Chelating agents bind to positively charged metal ions in solution and prevent them from forming insoluble precipitates with other ions that may be present. Calcium gluconate functions as a chelating agent over a wide pH range. It is efficient in forming stable chelates with divalent and trivalent metal ions such as potassium, copper, iron, aluminum, and other metals, reducing the adverse effects these metals can have on systems. In addition, calcium gluconate acts as a humectant, which means that it attracts water and increases hydration in products such as moisturizers and other personal care products. Calcium gluconate is used as a chelating agent, sequestrant, humectant, and skin conditioning agent in a variety of applications and product sectors. NOTE: The data provided in this assessment came primarily from the US EPA final designation report, Supporting Information for Low-Priority Substance D-Gluconic Acid, Calcium Salt (2:1) (Calcium Gluconate) (https://www.regulations.gov/document?D=EPA-HQ-OPPT-2019-0109-0009). According to US EPA, “low-priority substance designations give the public notice of chemical substances for which the hazard and/or exposure potential is anticipated to be low or nonexistent and provides some insight into which chemical substances are likely not to need additional evaluation and risk management under TSCA.”

Rationale
Available data is insufficient for GHS classification: calcium gluconate’s endogenous nature, transformation profile, a lack of structural alerts in the parent chemical substance, and experimental genotoxicity results provide sufficient information to indicate that this chemical has low concern for carcinogenicity.

Rationale
Multiple studies provide sufficient evidence to indicate low concern for genotoxicity.
NC
Rationale
Lower confidence due to use of combined repeat dose, reproductive, developmental toxicity study and use of analog. No reproductive effects were observed in an OECD 422 study on an analog which provides sufficient evidence to indicate low concern for reproductive toxicity.
