Different stereoisomers exist, including L(+)-Lactic acid and DL-Lactic acid, each with distinct properties and applications. The search intent often revolves around understanding the purity, physical characteristics, and potential contaminants associated with high-concentration lactic acid solutions.

When referring to Lactic Acid 90%, this signifies a solution where lactic acid constitutes approximately 90% of the total volume or mass.L(+)-Lactic acid 90% ≥90% Ph. Eur. The remaining percentage is typically water. Such solutions are commonly used in industrial settings due to their concentrated nature. For instance, L(+)-Lactic acid, 90% solution in water is a frequently specified product for various chemical processesLactic acid 90% can be used for acidifying cosmetics. For creams and other emulsions, do this in the aqueous phase. Can be purchased at De Hekserij..

Several key parameters are monitored to define the quality and suitability of Lactic Acid 90%. One such parameter is the BET (Brunauer-Emmett-Teller) surface area, although this is more commonly associated with solid materials and porous structures. In the context of liquid lactic acid, related measurements like density and viscosity are more pertinent.Excipients for injectable formulations However, interpretations of SERP data suggest that BET might be mentioned in conjunction with the production or characterization of materials derived from lactic acid, such as poly(lactic acid) polymers, where surface area is a critical property.

Quality Control and Impurity Limits

For Lactic Acid 90%, particularly when intended for applications where purity is paramount, stringent quality control measures are in place. These often involve setting maximum limit values for various impurities. For example, some specifications for L(+)-Lactic acid 90% indicate a Max. 200 ppm for Calcium (Ca) and Heavy metals (as Pb). Similarly, other grades specify Max. 10 ppm for Heavy metals (as Pb) and Iron (Fe). These limits are crucial for preventing undesirable side reactions or contamination in downstream processes, especially in food or pharmaceutical applications where such impurities can pose health risks.
