Mixing method:
- Pre-dissolve in purified water, water/propanediol, water/butylene glycol, or water/glycerin before adding to the main batch.
- Add during the final cool-down step when the formula is below 40°C. Avoid hot emulsification, hot-fill processing, and prolonged heating.
- Recommended finished-product pH: 5.0-7.0.
- Confirm clarity, preservative compatibility, scalp comfort, and peptide recovery in the finished formula.
Usage rate: 0.001-0.01% of pure peptide powder. Start at the low end for prototypes and adjust according to product concept, stability, and scalp comfort.
Product characteristics: White to off-white powder.
Solubility: Best prepared as a water/glycol stock solution before adding to the formula.
