Tests pH levels 1 – 14
Each booklet contains 80 strips.
Use these strips to measure the pH of your soap and cosmetics.
To test the pH of soap, wet your soap with water, and rub your hands on the soap to form bubbles. Put your pH strip onto the wet soap and check your reading. You don’t want your soap to be above a 10 pH.
For cosmetics – Immerse a strip into the product for up to 2 seconds and then remove. Shake of excess liquid. Compare the colour produed on the strip with the colour chart within 5 seconds to determine pH of the solution. A good pH range for skin care is 5 – 6
