| Toxizitätsübersicht | 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...Ethyl Glycolate...Safe for use in cosmetics, with qualifications |

Anwendungen & Verwendung
Verwenden
Ethyl glycolate, is an important building block for the preparation of agrochemicals and medicinal compounds. It is an important raw material and intermediate used in organic synthesis, pharmaceuticals, agrochemicals and dye stuff. It is also used in synthetic chemistry, discovery process and R&D. It also can be used as solvents.
