FORMULATION GUIDELINES
| INCI | Allantoin |
|---|---|
| Chemical Class | Skin protectant active |
| Solubility | Sparingly soluble in water. Solubility increases with heat. |
| Use Rate | 0.1–0.5% for most leave on formulas. Up to 1% if your system can hold it without crystallising. |
| pH Stability | Works well across typical cosmetic pH ranges. We recommend finished product pH 4.5–7.0. |
| Temperature Tolerance | We recommend dissolving in the water phase at 60–80°C until fully clear, then cooling with steady mixing to reduce recrystallisation. |
| Pro Tip | If crystals appear after 24–72 hours, reduce the dose, increase dissolve time/temperature, and slow your cool down. In gels, fully hydrate your polymer before final pH adjustment. |
| Appearance | White, odourless crystalline powder |
| Stability Notes | Main risk is recrystallisation. Proper dissolve and controlled cooling prevent gritty texture and fallout. |
| Storage | Keep sealed, cool and dry. Protect from moisture and direct heat. |
