General Information

Lactic acid is an organic acid occurring naturally in the human body and in fermented foods. It is used in a wide range of food, beverage, personal care, health care and chemical products as a mild acidity regulator with flavour enhancing and antibacterial properties. The commercial production of lactic acid is typically done by fermentation. Because the L(+) form is preferred for its better metabolisation, Jungbunzlauer has chosen to produce pure L(+)-lactic acid by traditional fermentation of natural carbohydrates.

Jungbunzlauer L(+)-lactic acid is a colourless to yellowish, nearly odourless, syrupy liquid with a mild acid taste. It is commercially available as aqueous solutions of various concentrations. These solutions are stable under normal storage conditions.
Lactic acid is non-toxic to man and the environment, but concentrated solutions of lactic acid can cause skin irritation and eye damage. They have thus to be labelled with a hazard pictogram and related statements. Lactic acid is easily biodegradable.


Jungbunzlauer L(+)-lactic acid food grade is supplied in accordance with the requirements of Commission Regulation (EU) No. 231/2012 and of the latest edition of the Food Chemicals Codex (FCC). Jungbunzlauer also proposes L(+)-lactic acid in high quality cosmetic and technical grades.

Several grades and types of Jungbunzlauer L(+)-lactic acid are currently available:

Food grade solutions:
50 % and 50 % heat stable
80 % and 80 % heat stable
88 % and 88 % heat stable
90 % heat stable

Cosmetic grade solutions:
90 % heat stable

Technical grade solutions:
80 %
88 %

Jungbunzlauer L(+)-lactic acid is supplied in bulk, in intermediate bulk containers (IBCs) with 1200 kg net weight (1100 kg net for the 50 % solutions), in drums with 250 kg net weight (240 kg net for the 50 % solutions) and in small drums with 25 kg net content (20 kg for the 50 % solutions).
