L-malic acid

L-malic acid (CAS 97-67-6), also known as L-hydroxysuccinic acid, is a naturally occurring organic acid used across food, pharmaceutical, and cosmetic manufacturing. It functions primarily as an acidulant, pH regulator, and flavor enhancer. This compound delivers a smooth, tart taste profile preferred over sharper mineral acids in many formulations. In food and beverage production, it acidulates fruit-flavored confectionery, soft drinks, and low-calorie products.

Its lingering tartness often outperforms citric acid in specific applications. Pharmaceutical formulators use it to adjust pH in oral solutions, effervescent tablets, and chewable dosage forms where taste masking is critical. In personal care, it acts as a pH buffer in leave-on skin formulations and mild chemical exfoliant systems. Its antimicrobial contribution also supports preservation in acidified food systems and topical cosmetic products.

L-malic acid is supplied as a white crystalline powder or granule. Standard grades include food-grade (FCC), pharmaceutical-grade (USP/BP), and technical-grade for industrial applications. Packaging typically ranges from 25 kg bags to bulk quantities. Food and pharma grades are supported by full documentation including certificates of analysis and origin to ensure compliance with global safety standards.
