Adjusting pH of Your Cream with Acetyl Tyrosine

You are asking about adjusting the pH of your oil-free cream containing Acetyl Tyrosine, Hyaluronic Acid, Q10, peptides, amino acids, Dimethicone, conditioner easy quat 39, Carbomer, and Glycerin to a pH of 6.8-6.9 using water and Triethanolamine, and if this pH affects the efficacy of Acetyl Tyrosine.

• pH Adjustment Method: Yes, using Triethanolamine is a common and effective method to raise the pH of cosmetic formulations, especially those containing Carbomer, which requires neutralization to form a gel structure. You can prepare a solution of Acetyl Tyrosine in water and then add Triethanolamine dropwise while mixing and measuring the pH until the desired range of 6.8-6.9 is reached. This solution can then be incorporated into your cream formulation.

• Effect on Acetyl Tyrosine Efficacy: A pH range of 6.8-6.9 is generally considered skin-compatible and is within a typical range for many cosmetic products. The stability and optimal efficacy pH for Acetyl Tyrosine can vary depending on the specific type and supplier of the ingredient. Without specific technical data for the Acetyl Tyrosine product you are using, it is difficult to definitively say whether a pH of 6.8-6.9 is ideal for its maximum efficacy or if it might reduce its activity compared to another pH. However, this pH range is not typically associated with rapid degradation of many common cosmetic actives.

In summary, using Triethanolamine to adjust the pH of your formulation to 6.8-6.9 is a standard practice, particularly given the presence of Carbomer. While this pH is generally suitable for cosmetic use, the precise impact on Acetyl Tyrosine's efficacy depends on the specific ingredient's properties.
