Sunscreen spray has a pungent paint smell, which may be caused by the following reasons:

1. The formula contains organic silicon compound, which smells like paint.

2. This product contains volatile substances, such as alcohol and acetone, which will give off some irritating smells.

3. The packaging is not well sealed, which causes the sunscreen spray to react with the substances in the air, thus producing some peculiar smell.

It should be noted that these reasons do not apply to all sunscreen spray products. If the sunscreen spray you bought has a pungent paint smell, it is recommended to stop using it and report it to the relevant departments.
