What's wrong with foundation that's hard to wash off?

The reason why foundation is hard to wash off is mainly because its ingredients contain some chemicals that are difficult to be dissolved by water. Foundation as a cosmetic, its main ingredients include various pigments, oils, moisturizers, preservatives, etc. These ingredients will form a film after drying on the skin or clothing, which is highly adhesive and waterproof, so it is difficult to be removed directly by ordinary water or detergent. 12

To clean foundation more effectively, the following methods can be used:

For fresh foundation stains, it is best to treat the stain while it is still wet. You can apply an appropriate amount of detergent to the stain and leave it for 10-20 minutes for normal cleaning.

For aged foundation liquid stains, you can apply detergent to the stain, leave it for 30 minutes, then use laundry detergent and color bleach and wash it at a water temperature of 40-60 degrees.

For stubborn foundation stains, you can choose to use a degreaser for dry cleaners, dab it on the stain, leave it for 10-15 minutes and then wash normally.

For chemical fiber clothing, try using a mixture of a small amount of water, alcohol, hydrogen peroxide and dishwashing detergent, brush the stain with a soft brush, leave it for 5-10 minutes and then gently rub and wash.

In addition, if foundation has accidentally rubbed off on your clothing, you can also use a puff cleaner or makeup remover to clean it. Avoid using ordinary soaps and laundry detergents as these may not be effective in removing foundation stains.

To summarize, foundation is difficult to clean because the pigments and oils in its composition form a film that is difficult to wash off after drying. Foundation stains can be effectively removed by the above methods.
