What Is Benzilic acid?
Benzilic acid is a white to tan solid that is sometimes used in cosmetics to help balance the acidity levels. It's also known as 2-hydroxy-2,2-diphenylacetic acid and is a type of 2-hydroxy monocarboxylic acid. Basically, it helps keep things stable and prevent too much acidity from building up.
What is the purpose of Benzilic acid in personal care products?
It is used for its buffering
characteristics.
Benzilic acid regulates the pH balance.
Names and identifiers that we found for this substance include: Benzilic Acid, Hydroxy(diphenyl)acetic acid, and "Benzeneacetic acid, α-hydroxy-α-phenyl-".
What Are Buffering Ingredients?
Benzilic acid has buffering characteristics.
Buffering ingredients helps regulate and maintain the pH balance of cosmetic products. The pH scale is a method used to determine a mixture's acidity or alkalinity level. Our skin's natural pH balance helps it stay healthy and function properly. When cosmetic products are applied to the skin, they can alter the pH balance, potentially causing irritation or other adverse effects.
Buffering ingredients neutralize or adjust the pH of cosmetic products to match that of the skin, which helps minimize the risk of irritation or damage. By maintaining a consistent pH balance, buffering ingredients can also improve the stability and effectiveness of a product's active ingredients.
Types of Buffering Ingredients
Here are some of the most common types of buffering ingredients:
Alkalis: These have a high pH and are used to neutralize acids. They help maintain the product's pH within a desired range.
Acids: These have a low pH and are used to neutralize alkalis. They help maintain the cosmetic product's pH within a desired range.
Salts: These are formed when an acid and a base (alkali) are mixed. They help maintain the cosmetic product's stability by preventing changes in pH caused by external factors such as heat or exposure to air.
Safety
Remember, always read and follow the instructions provided on product labels carefully. If you have any questions or concerns about using a product containing various ingredients, consult with your doctor or healthcare provider before use.
