Hi,
I'm really confused about something
I wanted to make a salicylic acid toner and a lactic lotion. Here's a formula I got from garden of wisdom.
The math formula used for this is:
120 grams or 4 oz x 10% (final strength) divided by 88% (strength of acid)
equals 13.8 grams or .46 ounce (these can be rounded to make formulating easier)

I have 40% lactic acid and I wanted to make some lactic lotion.I read some threads about lactic lotions, but it doesn't say anything about diluting acids with a lower concentration.
What I want to know is, if I have a lower concentration of the acid would I need to add more? Has anyone made a lotion/cream/toner with a lower strength acid?
Using that formula above, if I wanted to make 12% 100ml lotion, I'd need to add 30ml of the 40%?
Thanks
