Package Contents
Each pack contains:
- 1 × 10 mg Acetyl Octapeptide-3 powder
- 1 × 3 ml cosmetic solvent
The peptide is supplied as a dry powder to maximise stability during storage. A separate cosmetic solvent is included so you can prepare a stock solution at the concentration that best suits your formulation.
Preparing Your Stock Solution
Add the desired amount of the supplied solvent to the peptide vial and swirl gently until the powder has completely dissolved.
The amount of solvent added determines the concentration of the stock solution.
| Solvent Added | Stock Solution Concentration |
|---|---|
| 1.0 ml | 1.00% (10 mg/ml) |
| 1.5 ml | 0.67% (6.67 mg/ml) |
| 2.0 ml | 0.50% (5 mg/ml) |
| 2.5 ml | 0.40% (4 mg/ml) |
| 3.0 ml | 0.33% (3.33 mg/ml) |
Choosing Your Stock Concentration
- 1 ml (1%) – Ideal for formulators who prefer a concentrated stock solution and simple calculations.
- 2 ml (0.5%) – A balanced concentration suitable for most formulations.
- 3 ml (0.33%) – Produces a more dilute stock solution for formulations requiring lower peptide concentrations.
Recommended Cosmetic Use Level
Typical use level in finished cosmetic formulations:
- 0.01–0.05% – Daily maintenance products.
- 0.05–0.10% – Standard anti-ageing serums and creams.
- 0.10–0.30% – Intensive anti-ageing formulations.
- Maximum recommended: 0.50%
Storage
Store the unopened peptide powder in a cool, dry place away from direct sunlight. For long-term storage, refrigeration or freezing is recommended.
For best quality and performance, prepare only the amount of stock solution required for your formulation.
Once the peptide has been dissolved in the supplied solvent, it is recommended that the solution is used immediately in your cosmetic formulation. Reconstituted peptide solutions are more susceptible to degradation and contamination than the dry powder.
If the entire vial is reconstituted, it is recommended to use the solution promptly rather than storing it for future use.
