Lactic acid and lactobionic acid are both alpha-hydroxy acids (AHA) that have gained some popularity in the health and beauty industry. They both have exfoliating properties that can make the skin smoother, brighter and softer. Both acids are also present in a variety of products such as cleansers, toners, and moisturizers. However, there are differences between the two that can affect how they work and how they react with the skin.
What Are Lactic Acid and Lactobionic Acid?
Lactic acid is a naturally occurring chemical that is produced by the fermentation of sugar. It can be found in milk and yogurt, and it is also produced by the body during workouts. In the case of skincare products, lactic acid is usually derived from plant or dairy sources. On the other hand, lactobionic acid is a more recently discovered AHA. It is made by oxidizing lactose, which is the sugar found in milk. This process yields a larger molecule that is said to penetrate the skin more slowly than lactic acid.
Lactic acid is a popular ingredient in skincare products due to its exfoliating properties. It works by breaking down the bonds between dead skin cells, allowing them to be easily removed from the surface of the skin. This can help to improve the texture and tone of the skin, as well as reduce the appearance of fine lines and wrinkles.
Lactobionic acid, on the other hand, is known for its hydrating and antioxidant properties. It is said to be less irritating than other AHAs, making it a good option for those with sensitive skin. Additionally, it has been shown to help improve the skin's barrier function, which can help to reduce moisture loss and improve overall skin health.
The Chemical Structure and Properties of Lactic Acid
The chemical formula of lactic acid is C3H6O3. It is a colorless or yellowish liquid that has a sour taste and a mild odor. Lactic acid is an alpha-hydroxy acid with a pH level of around 3.8. This pH level is low enough to allow it to penetrate the skin and provide an exfoliating effect. Lactic acid is known to be a mild acid that is often used in low concentrations to avoid irritating the skin. However, it can be more potent in higher concentrations or if left on the skin for too long.
Lactic acid is produced naturally in the body during intense exercise when the muscles are deprived of oxygen. This process is known as anaerobic respiration and is responsible for the burning sensation felt in the muscles during exercise. Lactic acid is also found in many fermented foods such as yogurt, sauerkraut, and pickles. It is used in the food industry as a preservative, flavoring agent, and pH regulator. Additionally, lactic acid is used in the production of biodegradable plastics and as a raw material in the pharmaceutical industry.
The Chemical Structure and Properties of Lactobionic Acid
The chemical formula of lactobionic acid is C12H22O12. It is a white crystalline powder that is slightly soluble in water.
