SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.

Based on the available information included in this report, the CIR Expert Panel concludes that Glycolic and Lactic Acid, their common salts and their simple esters, are safe for use in cosmetic products at concentrations less than or equal to 10%, at final formulation pH greater than or equal to 3.5, when formulated to avoid increasing sun sensitivity or when directions for use include the daily use of sun protection. These ingredients are safe for use in salon products at concentrations less than or equal to 30%, at final formulation pH greater than or equal to 3.0, in products designed for brief, discontinuous use followed by thorough rinsing from the skin, when applied by trained professionals, and when application is accompanied by directions for the daily use of sun protection...Calcium Lactate...

Calcium lactate used as a general purpose food additive is generally recognized as safe when used in accordance with good manufacturing or feeding practice.

A - Alimentary tract and metabolism

QA - Alimentary tract and metabolism

In aqueous environments such as the gastrointestinal (GI) tract, calcium lactate will dissociate into calcium cation and lactic acid anions, the conjugate base of lactic acid. Lactic acid is a naturally-occurring compound that serves as fuel or energy in mammals by acting as an ubiquitous intermediate in the metabolic pathways. Lactic acid diffuses through the muscles and is transported to the liver by the bloodstream to participate in gluconeogenesis.

In hepatic gluconeogenesis, lactic acid is converted to glucose. Lactic acid may be further catabolyzed in the lactic acid cycle.

In order to be absorbed, calcium must be in its freely soluble form (Ca2+) or bound to a soluble organic molecule. Calcium absorption mainly occurs at the duodenum and proximal jejunum due to more acidic pH and the abundance of the calcium binding proteins. The mean calcium absorption is about 25% of calcium intake (range is 10 – 40%) in the small intestine, and is mediated by both passive diffusion and active transport.

Following oral administration to a human volunteer, 20 to 30% of a dose of lactic acid of up to 3000 mg was excreted via the urine during a period of 14 hours.

The majority of calcium absorbed (99%) is stored in the skeleton and teeth for structural integrity.

No pharmacokinetic data available.
