1. Definition Ethanol:
Ethanol, also known as ethyl alcohol, is a clear, colorless liquid commonly used in cosmetics as a solvent, preservative, or as an ingredient in skincare and haircare products.
2. Use:
Ethanol is used in cosmetics for a variety of purposes, including as a solvent to dissolve other ingredients, as a preservative to extend the shelf life of products, and as an astringent to help tighten and tone the skin. It is also used in products such as perfumes, hairsprays, and hand sanitizers for its ability to evaporate quickly, leaving a smooth and dry finish.
3. Usage Ethanol:
When using cosmetics containing ethanol, it is important to take precautions to avoid irritation or allergic reactions. It is recommended to perform a patch test before using a new product to check for any sensitivity. Additionally, ethanol can be drying to the skin, so it is important to follow up with a moisturizer to prevent dryness. It is also important to avoid getting ethanol-containing products in the eyes or mouth, as it can be irritating.
