✨One of the most important, but often overlooked step in formulating, is pH.
✨pH is the measurement of how Acidic or Basic a solution is.
✨pH is important because many ingredients we use to formulate, like preservatives, ascorbic acid, AHAs,BHAs, polymers, etc are all pH sensitive.
✨How do you measure pH? ➡️ using pH meter or pH strips. ➡️ I don’t like strips ➡️Cheap pH meters (less than $50) only take pH of liquids. ➡️ If you want to take pH of thick solutions, make sure the meter says it works in thick solutions. Often around $100. Affiliate Link to one I use amzn.to/3L8oRC4
✨ To take pH of product, pour a small amount in a 25ml or 50ml beaker and place in pH meter. Let sit for about 1 minute for pH to settle.
✨ You can lower the pH by using a 10% dilution of citric acid in distilled water or by using a 10%, 20%, 30% dilution of lactic acid
➡️ add 1-2 drops of your pH adjusted at a time into your product. Mix in the pH adjusted and wait 1 minute before taking the pH again. Keep repeating process until you reach desired pH. Do not pour pH testing solution back into product.
✨ Raise pH by using Triethanolamine, L-Arginine Powder, or Sodium Hydroxide ➡️ use Triethanolamine, as is(does not need diluted before using ➡️ make a 10% dilution of L-Arginine Powder with distilled water. (Learned method from @revegacosmetics ) ➡️ follow proper safety precautions when using sodium hydroxide. Always pour the sodium hydroxide into the water and be outside while doing this. Make a 10% -50% dilution. Or buy a 50% dilution from @formulatorsampleshop
✨ store pH adjusting solutions in cool dark place. No preservative needed. Remake monthly.
