Answer
Tranexamic Acid in Shower Gel
Tranexamic Acid can be used in water-based formulations like shower gels, as it is water-soluble. It is typically used as a whitening agent to brighten skin and address blemishes.
Based on the product information available:
- Charge: The charge of Tranexamic Acid is not specified in the product descriptions.
- Incompatibilities:
- For the standard Tranexamic Acid (Trans-White™), it is recommended to add ActiveProtec™ OX to help prevent long-term discoloration in the formula.
- For Nano-TXA™ (Tranexamic Acid Nano Emulsion, Penetration Base), you should not add any oil or oil-soluble ingredients, as this will affect the particle size of the nanoemulsion.
- Usage Rate: The recommended usage rate for cosmetic purposes is typically up to 3%. Using more than 3% may require registration as a medicine.
- pH: The formula should ideally have a pH in the range of 3-8.
While Tranexamic Acid is water-soluble and can be incorporated into water-based systems, its effectiveness in a rinse-off product like shower gel compared to leave-on products (creams, serums) may be limited due to the short contact time with the skin.
