- Apply 0.6 – 1.2 gallons per acre-foot of water.
- General guideline: 1 gallon per 1.5 acre-feet.
- Dilute with a minimum of 9 parts water.
- Spray uniformly over the water surface using coarse droplets.

Great value and very practical
Style: SPF 50, Size: 8 Fl Oz (Pack of 6)
This sunscreen is a great value for the price. The SPF 50 protection works well and the lotion applies smoothly without feeling too greasy. It absorbs nicely and provides good coverage for outdoor activities.
I especially like using these bottles to refill the sunscreen dispensers at my Airbnb for guests. It’s convenient, reliable, and affordable when you need multiple bottles available.
Overall, it’s a solid everyday sunscreen and a very practical option if you need good protection at a reasonable price.

good price for good product. applies well, shake and store upright
Style: SPF 50, Size: 8 Fl Oz (Pack of 1), Style: SPF 50, Size: 8 Fl Oz (Pack of 1)
I believe it is equal to the name brands
It is 50 SPF Sun Protection Factor so it offers strong UV A and UV B protection which are the 2 ranges of sun rays that do the skin damage and burning.
It is an easily absorbed lotion that when rubbed goes into the skin and is not visible. It is thick and goes on with a non shiny, non greasy, solid thick feeling which is what we need for it to stay on as long as possible.
It feels good after being rubbed in in that it feels dry and not overly greasy or with no shine and sheen.
It is a good product and offers burn protection to me in some clear-sky strong sun uses.
Reapply after entering the pool water or swimming laps and after an hour (all sunscreen labels say reapply after 80 minutes which I believe is per recommendations of the federal FDA or some medical studies).
I reapply often and I still get tanned but I do not want to burn.

Survived the sun like a pasty legend
Style: SPF 50, Size: 8 Fl Oz (Pack of 1)
I bought this sunscreen because I’m basically a human marshmallow — one hour in the sun and I’m toasted. This Amazon Basics Sport SPF 50? It’s like armor for the pale and easily crisped. I slathered it on before a full day of hiking, sweating, and pretending I enjoy direct sunlight, and guess what? No burn. Not even a pink glow. Just victory.
It goes on smooth, doesn’t feel greasy, and somehow stayed put through sweat, water, and my dog licking my arm. It’s fragrance-free, which means I didn’t smell like a coconut smoothie or a chemical spill — just clean and protected.
Pros:
• High SPF that actually works
• Sweat and water resistant — like, impressively so
• No greasy residue or weird smell
• Affordable and comes in a big ol’ bottle
• Didn’t turn me into a lobster (the bar is low, but still)
Minor feedback:
It’s not fancy or trendy, but honestly, I’m here to not burn — not win a skincare award. Also, it takes a bit of rubbing in, but once it’s on, it’s locked and loaded.
Final thoughts:
If you want solid sun protection without the drama, this stuff delivers. Whether you’re hiking, swimming, or just trying to survive summer, it’s a reliable sidekick. Would absolutely buy again — my skin demands it.

Great Sunscreen at a Great Price!
Style: SPF 50, Size: 8 Fl Oz (Pack of 1)
Love this sunscreen. I live in FL and like to walk most mornings, and need a good sunblock. This Amazon Basics is far better than my previous, far more expensive brand. It's a great price for great quality. I've been using it on my body & face, it's non-greasy, absorbs well, and really seems to offer very good sun protection. And I really appreciate the next day shipping on my past two orders, Amazon. Thanks for the great product & great service!

Works when working outside and heavy activities
Style: SPF 50, Size: 8 Fl Oz (Pack of 1)
I use it as an Amazon delivery driver, and it works in the heat and sweat is no issue it does last for 2 hours. Reapplying it is extremely easy, no burns or sun damage to my skin. I can tell you it works cause I’m recovering from skin cancer and it works no problems or anything.
