Does this roll come in something to protect it from light?

The roll is in foil inside the plastic case which is inside a box that you can keep it in.

Does it work to test cosmetics, like shampoo and conditioners?

It will likely work, however such things tend to have dyes in them. So I would suggest only placing this on one side of the paper and then reading the other side of the paper.

Can these be used to test vaginal pH?

The 325 tape would be better ranges for this type of testing. Do not use the tape internally. Take your cm sample and apply it to the tape and read the range. https://www.amazon.com/dp/B00D6ML83M?ref=myi_title_dp

how many tests will this product acheive?

Don't know exactly. Depends on how long strip you use for each test. I normally use less than an inch. Take care to make sure the ph of your fingers don't affect the results on the test strip. It could transfer over if your fingers are wet when you hold the test strip- Kent
