What is DL-Lactic acid

**Introduction to DL-Lactic Acid** DL-Lactic acid is a versatile organic compound widely used in food, pharmaceutical, cosmetic, and industrial applications. As a racemic mixture of D- and L-lactic acid, it serves as a key ingredient in food preservation, flavor enhancement, and pH regulation. In the pharmaceutical industry, it is utilized in biodegradable polymers, drug delivery systems, and surgical sutures. The cosmetic sector values DL-lactic acid for its exfoliating and moisturizing properties in skincare products. Additionally, it plays a crucial role in producing biodegradable plastics, such as polylactic acid (PLA), supporting sustainable manufacturing. With its broad functionality and eco-friendly benefits, DL-lactic acid is a vital component in modern industries.

Preparation Process: **Preparation Method of DL-Lactic Acid:** DL-Lactic acid is typically synthesized via the fermentation of carbohydrates (e.g., glucose or sucrose) using *Lactobacillus* bacteria under anaerobic conditions. The fermentation broth is acidified, and the lactic acid is separated via filtration, followed by purification through esterification with methanol to form methyl lactate, which is then hydrolyzed back to lactic acid. Alternatively, chemical synthesis involves the hydrolysis of lactonitrile (derived from acetaldehyde and hydrogen cyanide) with sulfuric acid, yielding racemic DL-lactic acid. The crude product is purified via distillation or crystallization. Industrial methods may combine fermentation and chemical steps for cost efficiency.

Usage Scenarios: DL-Lactic acid, a racemic mixture of D- and L-lactic acid, is widely used in the food industry as a preservative, acidulant, and flavor enhancer. It is employed in pharmaceuticals as an excipient and in topical formulations for skin exfoliation. In cosmetics, it acts as a moisturizer and pH adjuster. Industrially, it serves as a biodegradable precursor for polylactic acid (PLA) production, used in eco-friendly plastics. Additionally, DL-lactic acid is utilized in textile dyeing, leather tanning, and as a cleaning agent due to its mild acidity. Its antimicrobial properties make it valuable in animal feed and agricultural applications.

10.3 Possibility of hazardous reactions

LACTIC ACID is a carboxylic acid. Carboxylic acids donate hydrogen ions if a base is present to accept them. They react in this way with all bases, both organic (for example, the amines) and inorganic. Their reactions with bases, called "neutralizations", are accompanied by the evolution of substantial amounts of heat. Neutralization between an acid and a base produces water plus a salt. Carboxylic acids with six or fewer carbon atoms are freely or moderately soluble in water; those with more than six carbons are slightly soluble in water. Soluble carboxylic acid dissociate to an extent in water to yield hydrogen ions. The pH of solutions of carboxylic acids is therefore less than 7.0. Many insoluble carboxylic acids react rapidly with aqueous solutions containing a chemical base and dissolve as the neutralization generates a soluble salt. Carboxylic acids in aqueous solution and liquid or molten carboxylic acids can react with active metals to form gaseous hydrogen and a metal salt. Such reactions occur in principle for solid carboxylic acids as well, but are slow if the solid acid remains dry. Even "insoluble" carboxylic acids may absorb enough water from the air and dissolve sufficiently in it to corrode or dissolve iron, steel, and aluminum parts and containers. Carboxylic acids, like other acids, react with cyanide salts to generate gaseous hydrogen cyanide. The reaction is slower for dry, solid carboxylic acids. Insoluble carboxylic acids react with solutions of cyanides to cause the release of gaseous hydrogen cyanide. Flammable and/or toxic gases and heat are generated by the reaction of carboxylic acids with diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, and sulfides. Carboxylic acids, especially in aqueous solution, also react with sulfites, nitrites, thiosulfates (to give H2S and SO3), dithionites (SO2), to generate flammable and/or toxic gases and heat. Their reaction with carbonates and bicarbonates generates a harmless gas (carbon dioxide) but still heat. Like other organic compounds, carboxylic acids can be oxidized by strong oxidizing agents and reduced by strong reducing agents. These reactions generate heat. A wide variety of products is possible. Like other acids, carboxylic acids may initiate polymerization reactions; like other acids, they often catalyze (increase the rate of) chemical reactions. Slowly corrodes most metals (USCG, 1999).

  • Toxicity to daphnia and other aquatic invertebrates: no data available
  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: Lactic acid reached 22% of its theoretical BOD in 5 days using a sewage inoculum(1). In a closed bottle screening test, lactic acid, present at 2 mg/L, reached 12, 67, and 88% of its theoretical BOD after 5, 15, and 30 days, respectively, using an activated sludge inoculum(2). Lactic acid reached 59% of its theoretical BOD in 5 days using a sludge inoculum and the Warburg screening test(3). Lactic acid, present at 500 mg/L, reached 27.5, 29.4, and 33.3% of its theoretical BOD in 6, 12, and 24 hours, respectively, using an activated sludge inoculum at 2500 mg/L(4). Lactic acid was found to be easily biodegradable by biological sewage treatment(5). Lactic acid, present at 100 mg/L, reached 76% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test which classified the compound as readily biodegradable(6).

12.3 Bioaccumulative potential

An estimated BCF of 3 was calculated for lactic acid(SRC), using a log Kow of -0.72(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).

12.4 Mobility in soil

Experimental Koc values for lactic acid on a clastic mud (3.5% organic carbon) and a lateritic muddy sand (1.3% organic carbon) were 5.7 and <0.08, respectively(1). Utilizing an HPLC method, the Koc of lactic acid (93% aqueous solution) on soil and sewage sludge at neutral pH and pH 2 was <20.9(2). According to a classification scheme(3), these Koc values suggest that lactic acid is expected to have very high mobility in soil. The pKa of lactic acid is 3.86(4), indicating that this compound will exist partially to almost entirely in anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(5).
