MALIC ACID - Cosmetics Ingredient INCI (1)

Malic Acid is an organic alpha-hydroxy acid (AHA) commonly used in cosmetics for its exfoliating and skin-enhancing properties. It aids in dissolving the dead skin cells on the surface to reveal a smoother and more radiant complexion. It also enhances the skin’s hydration and improves its ability to hold moisture. This acid is commonly added to exfoliating creams, anti-aging products, and brightening formulations. In its raw form, Malic Acid appears as a white crystalline powder that is odorless. It is a stable ingredient but should be placed in a cold and dry place to prevent degradation. The chemical formula of Malic Acid is C4H6O5.

What is MALIC ACID used for?

Malic Acid is a powerful ingredient in cosmetics, renowned for its effective exfoliating properties. It gently removes dead skin cells and contributes to smoother and brighter skin. Its ability to adjust pH makes it essential for maintaining the stability and efficacy of various formulations. In anti-aging products, Malic Acid aids in reducing fine lines and wrinkles by accelerating cell turnover. Additionally, it enhances hydration by improving the skin’s moisture retention. Found in exfoliating masks, serums, and moisturizers, Malic Acid helps to brighten skin tone, improve texture, and provide overall skin health benefits.

Origin

Malic Acid is produced through the fermentation of carbohydrates, such as glucose or sucrose, by specific strains of bacteria or yeast. This process converts the carbohydrates into malic acid. Alternatively, it can be synthesized chemically from maleic anhydride through a hydration reaction. The resulting malic acid is then purified through crystallization and filtration.

Safety profile

Malic Acid is generally safe for use in cosmetics. It is well-tolerated by most skin types when used in appropriate concentrations, typically up to 10% in formulations. However, it can cause mild irritation or sensitivity in some individuals, especially those with sensitive skin. To minimize risk, it is best to perform a patch test before use and direct contact with the eyes should be avoided. Additionally, Malic Acid is biodegradable and good for the environment. It is also vegan and halal.
