BHA (Butylated Hydroxyanisole)

1. Definition BHA (Butylated Hydroxyanisole):

Butylated Hydroxyanisole (BHA) is a synthetic antioxidant commonly used in cosmetics to prevent oils and fats from becoming rancid. It is a white or yellowish waxy solid with a slightly phenolic odor.

2. Use:

BHA is primarily used in cosmetics and personal care products as a preservative to extend the shelf life of products by preventing the oxidation of oils and fats. It is also used as a stabilizer in products such as lipsticks, eyeliners, and foundations to prevent them from changing color or texture over time.

3. Usage BHA (Butylated Hydroxyanisole):

BHA is generally considered safe for use in cosmetics when used in concentrations of up to 0.5%. However, it is important to note that some individuals may be sensitive to BHA and experience skin irritation or allergic reactions. It is recommended to perform a patch test before using products containing BHA and to discontinue use if any adverse reactions occur. Additionally, BHA may be best avoided by pregnant women or individuals with certain medical conditions, so it is important to consult a healthcare professional before using products containing BHA.
