Frequently Asked Questions
Q1: What is the minimum purity requirement for BOC 157 peptide in cosmetic formulations?
For cosmetic formulation applications, the recommended minimum purity is ≥99% by HPLC. This level ensures that impurities do not affect product stability, color, or performance. Lower purity grades may introduce variability in formulation results and could lead to batch failures in commercial production.
Q2: How should BOC 157 peptide be stored to maintain its specifications?
BOC 157 peptide should be stored as a lyophilized powder at -20°C in a desiccated environment. Avoid repeated freeze-thaw cycles by aliquoting into single-use portions. Under these conditions, the peptide maintains its specified purity for up to 24 months. For solution preparation, use immediately and avoid prolonged storage in aqueous environments.
Q3: Can BOC 157 peptide be used in water-based cosmetic formulations?
Yes, but with considerations for solubility. BOC 157 peptide has limited water solubility (approximately 5 mg/mL). For water-based formulations, pre-dissolve in a small amount of DMSO or ethanol before adding to the aqueous phase. Alternatively, use specialized formulation techniques such as encapsulation or liposomal delivery to enhance dispersion and stability in water-based systems.
