L-Acid FAQ Section
Q: What makes L-Acid different from regular lactic acid?
A: L-Acid is the L-isomer of lactic acid, which is the naturally occurring form with higher biological compatibility. Unlike racemic mixtures, L-Acid offers superior performance in pharmaceutical applications where stereospecificity is crucial. Its molecular structure allows for better interaction with biological systems and enzymes.
Q: What are the primary storage requirements for L-Acid?
A: L-Acid should be stored in tightly sealed containers at temperatures between 15-25°C, protected from direct sunlight and moisture. The storage area should be well-ventilated and away from strong oxidizers. Under proper conditions, L-Acid maintains its stability for at least 24 months from the production date.
Applications of L-Acid
- Pharmaceutical Industry: Used as an acidulant and pH adjuster in drug formulations
- Food Processing: Acts as a preservative and flavor enhancer in various food products
- Cosmetics: Serves as a pH regulator and moisturizing agent in skincare products
- Biodegradable Plastics: Key component in the production of polylactic acid (PLA)
