Lactic acid 80% is a concentrated solution of lactic acid in water. Lactic acid itself is a naturally occurring alpha hydroxy acid (AHA) produced by the fermentation of sugars . It is found in sour milk products like yogurt and cheese, as well as in fermented vegetables like sauerkraut.
Here's a breakdown of lactic acid 80%:
- Concentration: This means the solution contains 80% lactic acid and 20% water.
- Uses:
- Food and beverage industry: Lactic acid, in lower concentrations, is used as an acidulant (souring agent) in various food and beverages. It also acts as a preservative in some products.
- Cosmetics industry: Lactic acid at lower concentrations (usually between 5% and 20%) is a common ingredient in skincare products due to its exfoliating properties. It helps remove dead skin cells, revealing brighter and smoother skin. However, 80% lactic acid is too strong for direct application on skin and needs significant dilution for cosmetic use.
- Pharmaceutical industry: Lactic acid is used in some medications, such as topical creams to treat warts and other skin conditions.
- Brewing industry: Lactic acid is used by some brewers to adjust the pH of their wort (unfermented beer) and create a tart flavor profile in certain beers.
