Disposing old sunscreen improperly is a wasteful and potentially harmful practice.
Disposing Old Sunscreen: A Guide
If you find yourself with unused sunscreen from previous summers or vacations, it's essential to dispose of it properly. Here's a comprehensive guide on how and why to get rid of old sunscreen.
Can I use old sunscreen?
It is not advisable to use sunscreen that has been stored for more extended periods. Old sunscreen may have lost its effectiveness in protecting your skin from harmful UV rays, leading to sunburn and skin aging. Moreover, it could potentially contain bacteria or harmful chemicals caused by oxidation or contamination.
Disposal Methods
Empty sunscreen containers can be placed in your household waste, similar to other packaging materials. However, for half-used bottles or tubes, remnants of expired sunscreen can be emptied into the regular trash, with one exception. Medical sunscreen may contain certain ingredients that require specialized disposal at a recycling center or hazardous waste collection point. Be sure to refer to the manufacturer's instructions on the packaging for specific guidance.
Shelf Life and Expiration Dates
Proper storage and regular checking are crucial for sunscreen maintenance. Sunscreen should ideally be stored in a cool, dry place away from direct sunlight. If the product has an unusual odor, changes in color, or a consistency different from original, discard it immediately.
Most sunscreens have a shelf life of about three years. Check the bottle for an expiration date or a "best used by" date, as these products are not intended to last longer than 30 months. If unsure about the product's condition, it is better to err on the side of caution and discard it.
Caution with Medical Sunscreen
Medical sunscreens might contain specific ingredients requiring special attention during disposal. In such cases, consider using local hazardous waste programs or hazardous waste collection points for disposal.
Common Sunscreen Ingredients and Their Implications
One specific ingredient to watch out for is octocrylene, a UV filter found in many sunscreens. When octocrylene comes into contact with oxygen and sunlight, it can form harmful chemicals called benzophenones. These are believed to affect hormone balance, reduce fertility, and possibly be carcinogenic. Therefore, it is best to discard any expired sunscreen containing octocrylene for reliable protection and to avoid any potential skin irritation.
Pro Tips
- Whenever you open a new bottle of sunscreen, write the date on the container for easier tracking.
- If possible, contact the manufacturer for details on take-back or recycling programs for packaging.
For more information on disposing of household hazardous waste, refer to local waste management programs or environmental, health, or solid waste agencies in your area. By following these guidelines, you can ensure that your sunscreen disposal is safe, environmentally friendly, and effective.
- Improper use of old sunscreen, especially if it has been stored for extended periods, may expose you to ineffective protection against harmful UV rays and potential bacterial or harmful chemicals.
- Instead of improperly disposing of old and expired sunscreens, consider the environment by learning proper disposal methods, such as recycling or using hazardous waste collection points, for sunscreen products containing specific ingredients, like octocrylene.
