Overview

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...Potassium Lactate...

Applications · 3 items

DescriptionPotassium lactate is a compound with formula KC3H5O3, or H3C-CHOH-COOK. It is the potassium salt of lactic acid. It is produced by neutralizing lactic acid which is fermented from a sugar source. It has E number "E326". Potassium lactate is a liquid product that is usually 60% solids but is available at up to 78 % solids. Potassium lactate is commonly used in meat and poultry products to extend shelf life and increase food safety as it has a broad antimicrobial action and is effective at inhibiting most spoilage and pathogenic bacteria. Potassium lactate is also used as an extinguishing media in the First Alert Tundra fire extinguishers.

UsesPotassium DL- Lactate is used in preparation of high solids and high protein lactose-free aseptic milk concentration and milk powders with forward osmosis.

UsesPotassium Lactate is a flavor enhancer that is the potassium salt of lactic acid. it is a hygroscopic, white, odorless solid and is prepared commercially by the neutralization of lactic acid with potassium hydroxide. it is used as a flavoring agent and enhancer in some meat and poultry products, a humectant, and a ph control agent.
