About the PH value of hair styling products

Postby ammez.info » Tue Oct 24, 2017 8:21 am

Dear Staff, I would like to know the product PH value จัดแต่งทรงผม should be where? We made it out without adding any PH adjuster. Measured out 7.1, which is neutral enough to be considered valid or not. or must be made into a weak acid I'd like to know the reason why it has to make makeup with a weak acidity. Thank you.

Hello, the pH of the skin and hair is on average 5.5. Products that are gentle on the skin and hair should not change or disturb the pH of the skin or hair. However, the right pH doesn't mean it has to be 5.5, but it means. reach that is close to this level but not much lower or much higher For example, it is very alkaline. It will cause dryness of hair and skin. Notice if you try to use alkaline soap. (Glycerin soap) to wash your face or wash your hair will find that it makes your skin or hair dry / hard. The pH level of the member's formula at 7.1 is not a problem because it is close to 5.5 already.

[quote="staff"]Hi, the pH of the skin and hair is averaged at 5.5. The product is gentle on the skin and hair, so it should not change or interfere with the pH of the skin or hair.

Triethanolamine down only 0.2%, intending to adjust PH down a bit, it appears that Emulsion is unstable. From the original product texture, soft and smooth. but after putting Triethanolamine into the crumbly product like soil. We've heard that adding acids and alcohals affect the stability of the emulsion. I want to know how we should fix between ; 1. Cut Triethanolamine out of formula (PH 7.1 is enough as suggested by Staff) 2. Replace Emulsion with another one (previously we used PEG-40 with Glyceryl Stearate SE ) 3. Add more Emulsion substances (previously we used 2 of them together, 8%, which we think is enough) Please advice, thank you.

Hello, pH 7.1. The team thinks it's appropriate. No need to adjust. Lactic Acid found in shampoo formulas. various brands The reason is because the researchers later discovered that Lactic Acid is beneficial for hair. Can help nourish the hair. Using Lactic Acid in the above formula. It's not for adjusting the pH of shampoo formula, but it's used to nourish the hair.
