L-Malic Acid
Formula:
C₄H₆O₅
GOST/CAS:
CAS 97-67-6
L-Malic Acid is a highly effective organic acid of natural origin, appearing as a white crystalline powder or granules with a smooth, clean tart taste and excellent solubility in water. In the industrial sector, it functions as a key acidity regulator, antioxidant, preservative, and chelating agent. Due to its unique organoleptic profile and high biocompatibility, L-malic acid is an indispensable raw material for creating stable, well-balanced formulations in the food and beverage industries, as well as in the Personal Care and household chemical sectors.
Applications
Food & Beverage Industry: Used as a synergistic acidity regulator (E296) in the production of carbonated and juice-based drinks, confectionery (gummies, hard candies, chewing gums), wines, and preserves. It enhances and prolongs fruit flavor perception.
Cosmetics & Personal Care: Incorporated into anti-aging products, chemical peels, toners, and shampoos as a mild AHA exfoliant. It regulates pH levels, stimulates cellular turnover, improves skin texture, and enhances hair shine.
Pharmaceuticals & Nutraceuticals: Used in effervescent tablets, cough syrups, and sports nutrition (within metabolic cycles to boost endurance) to mask the bitter taste of active ingredients and optimize solubility.
Textile & Chemical Industries: Applied in textile dyeing processes as a buffering agent, and used in detergent formulations as an eco-friendly chelating component.
Key Advantages
Enhanced Flavor Profile: Provides a smoother, more lingering tartness compared to citric acid. It perfectly masks unpleasant chemical or bitter aftertastes (e.g., from artificial sweeteners).
High Synergy & Solubility: Dissolves readily in water and alcohol. It exhibits an excellent synergistic effect when combined with other organic acids (citric, lactic, tartaric), thereby optimizing formulation costs.
Mild Keratolytic Action: In cosmetic applications, it acts more gently than other AHA acids, reducing the risk of skin irritation while maintaining high exfoliation efficiency.
Eco-Friendly & Biodegradable: A completely natural product that is safe for human health and the environment. It does not accumulate in ecosystems and is 100% biodegradable.
Storage & Transportation
- Store in dry, clean, cool, and well-ventilated warehouse facilities in tightly closed original packaging, protected from moisture, direct sunlight, and heat sources.
- Optimal storage conditions: relative humidity not exceeding 60%, temperature range from +5°C to +25°C. The product is hygroscopic; take measures to avoid caking.
