Important Information Regarding Sunscreen & Your Vinyl Liner. We all understand the dangers of the sun. It’s no secret that prolonged exposure to UV rays leads to sunburn and increases the risk of skin cancer. It’s also common knowledge that protecting your family and yourself with sunscreen is especially important. But did you know that some sunscreens contain chemical ingredients that may have adverse effects on your pool liner?
In testing, several different sunscreens were applied to directly to vinyl pool liner samples and placed in a 110° room up to 24 hours. The results showed that several of the sunscreens significantly damaged the print on the liner samples. Others had minor damage. The last group had no effect on the liner material. Of the sunscreens tested, the ones with more chemical ingredients, especially the compounds Phenoxyethanol (aka: Ehtylene Glycol, Monophenyl Ether, Glycol Etheror Phenoxytolarosol) and Octocrylene were more likely to damage the print on the liner. We recommend checking your sunscreen to avoid these chemicals, if possible. Mineral sunscreens did not have any impact on the liners tested.
