    What Does Lactic Acid Do?

    What Does Lactic Acid Do?

    Lactic acid is a common type of organic chemical, which is very often associated only with the production of yogurt. This association stems from its production during the fermentation process which transforms milk into yogurt. Similarly, lactic acid is used for its fermenting qualities in a wide range of products. However, this is not the only purpose it serves. Lactic acid uses span across industries. Diverse industries make products with lactic acid including medical, pharmaceuticals, textile, cosmetics, and more.

    Types of Lactic Acid

    Lactic acid can be naturally found or artificially manufactured to be utilized in different industries, It exists in two distinct forms including:

    L-lactic acid: This is the most commonly used form of natural lactic acid which is usually derived from organic sources. In terms of production, L lactic acid is a by-product of the anaerobic metabolism process which happens in all living organisms including human beings. Apart from this, it is also produced during the process of fermentation which makes it suitable for flavor enhancement uses, pH regulation purposes, and preservation of products.

    D-lactic acid: As opposed to L-lactic acid, D lactic acid is not as commonly produced through natural forms, and is more widely artificially produced. However, it is found in some quantities in the gastrointestinal tract and may be produced in limited quantities during the process of fermentation. In terms of usage, d-lactic acid is commonly used in a wide range of industries including pharmaceuticals and the production of bio-plastics.

    Uses of Lactic Acid

    For those wondering what is lactic acid used for? its versatility helps the substance find application in diverse industries including the following:

    In the Food Industry

    Within the food industry, lactic acid is used in various concentrations in the forms of lactic acid 88, lactic acid 90, and more. It is classified as a safe to consume substance and serves the following uses:

    Regulating pH Levels: The primary benefit offered by lactic acid for this sector is that it can regulate the acidulants and pH levels during food production. Lactic acid in drinks is popular because of this. This enables it to provide a mildly sour flavor to the foods, which helps in minimizing the pH levels of the food, playing a vital role in food preservation and safety.

    Prevents Growth Of Microbes: The acidification properties of lactic acid help prevent microbial growth including the growth of yeast, bacteria, and mold. This serves an important role in the preservation of foods like meats, dairy, seafood, poultry, etc.

    Improving Flavor: Lactic acid is a known flavor enhancement agent due to the mildly sour and tangy flavor it imparts to foods like cheese, sauerkraut, pickles, kombucha, and more.

    Transforming Texture: Change of texture is another important benefit provided by lactic acid. Due to this property, it helps in making the foods thick and creamy and allows them to retain more water.

    In The Cosmetics Industry

    Lactic acid uses for skin in the cosmetics industry is powered by its rejuvenating and repairing properties. For instance, bioscience lactic acid resurfacing night serum features lactic acid as a core ingredient. Its popularity stems from the following properties:

    Moisturization: One of the main advantages offered by lactic acid is its moisture attraction and retention properties, making it highly valuable for the skincare and cosmetics industry.

    Exfoliation: Another key advantage lactic acid offers is helping remove dead skin cells. Since lactic acid in face wash is rich in AHAs, it helps in getting rid of rough and dull skin, thereby helping with hyperpigmentation.

    Skin Treatment: Lactic acid’s collagen-boosting properties, exfoliation capabilities, and antibacterial benefits make it ideal for anti-aging products, lactic acid peel products, acne treatment products, and hyperpigmentation treatments. It can help fade dark spots on the skin, increase glow and elasticity, maintain optimum pH levels, and reduce the buildup of sebum.

    In the Medical and Pharmaceuticals Industry

    In the medical and pharmaceutical sectors, lactic acid serves the following purposes:

    Medical Implants: Production of Biomedical implants, sutures, and drug delivery systems is the primary benefit provided by lactic acid. The polymers created using lactic acid are widely used in drug delivery systems because they help enhance the efficacy of drugs and reduce side effects.

    Dermatological Uses: In dermatological utilizations, lactic acid plays a vital role in the creation of creams, lotions, exfoliants, and moisturizers which help in skin recovery and rejuvenation.

    Tissue Regeneration: Another key advantage is the role lactic acid plays in tissue regeneration, making it a vital component for wound recovery.

    In The Bioplastics Industry

    A derivative of lactic acid known as poly lactic acid is an essential substance used in the bioplastics industry for the following benefits:

    3D manufacturing: The field of 3D printing uses PLA as feedstock since these are compatible with 3D printers. Moreover, their versatility makes them suitable for the manufacturing of a wide range of products including models, prototypes, and other intricate products.

    Disposable products: Polymers made out of lactic acid are an essential component used in the making of disposable products like bowls, cutlery, etc. These are ideal for single-use products but are environmentally friendly and biodegradable, making them suitable to use.


    With such a versatile range of uses, lactic acid is undoubtedly a manufacturer-favorite. But, it is essential to buy it from reliable suppliers to ensure that you get the best lactic acid that is true to its claimed potency.
