Thinkbaby and Thinksport sunscreens come in 3oz and 6oz tubes made of environmentally friendly packaging that does not contain BPA, vinyl, or phthalates. The packaging and contents are environmentally safe. Each tube is marked with an expiration date. Note: The base formulations of our sunscreens are identical. We set out to make the most effective safe sunscreen possible. It didn't make sense to make one safe for babies, and a harmful version for adults. While this seems obvious, you should check out what the major brands are doing. Compare your sunscreen's "safe" ingredients to ours. The best way is to check out The Environmental Working Group's database Skin Deep http://www.EWG.org/SkinDeep The ratings for each ingredient are listed separately below. Our sun care products have been "1" rated since 2010!
