Glycerin is a high-performance humectant used to support hydration and barrier comfort.
It attracts water and helps reduce dryness, improving skin softness and flexibility over time.
In formulations, glycerin also improves product feel, reduces tightness after cleansing, and helps gels apply more smoothly.
It is one of the most dependable ingredients for everyday hydration across toners, serums, creams, cleansers, and hair products.

FORMULATION GUIDELINES
| INCI | Glycerin |
|---|---|
| Type | Humectant |
| Solubility | Water soluble (miscible) |
| Use Rate | 1–10% typical. 2–5% is common for serums and moisturisers. 3–8% is common for cleansers and body products depending on feel. |
| Best Phase | Water phase |
| pH Compatibility | Works across common skincare pH ranges. We recommend aligning pH to your active system. |
| Temperature Tolerance | Stable under normal processing |
| Pro Tip | Use glycerin to pre-disperse gums and polymers (like xanthan gum) to prevent clumps before adding to water. If your formula feels sticky, reduce the glycerin level and balance with a lighter humectant system or a polymer that improves slip. In rinse-off products, glycerin helps reduce tightness after cleansing and improves skin feel. |
| Appearance | Clear, colourless, viscous liquid |
| Stability Notes | Very stable. High levels can increase tack and may thin some surfactant systems depending on blend. |
| Storage | Keep sealed, cool and dry. |
