TBHQ

1. Definition TBHQ:

TBHQ, or tert-Butylhydroquinone, is a synthetic antioxidant commonly used in cosmetics to prevent oxidation and extend the shelf life of products. It is a white, crystalline powder with a mild odor.

2. Use:

TBHQ is used in cosmetics as a preservative to prevent the deterioration of oils and fats in products such as lipsticks, eyeliners, and moisturizers. It helps to maintain the stability and quality of the formulation by inhibiting the formation of free radicals and preventing rancidity.

3. Usage TBHQ:

When using cosmetics containing TBHQ, it is important to follow the recommended guidelines and avoid excessive exposure to the ingredient. While TBHQ is generally considered safe for use in cosmetics at low concentrations, some individuals may experience skin irritation or allergic reactions. It is advisable to perform a patch test before using products with TBHQ, especially if you have sensitive skin or a history of allergies.
