In skin care formulations, Polyquat 7 provides a silky feel and enhances skin hydration. It is also known for its ability to reduce static, improve the spreadability of formulations, and enhance the overall sensory profile of the product.
Polyquat 7 is compatible with a variety of other ingredients and is often used in gentle formulations, including those for sensitive skin or hair.

FORMULATION GUIDELINES
| INCI | Polyquaternium-7 |
|---|---|
| Type | Cationic conditioning polymer |
| Solubility | Water soluble |
| Use Rate | 0.5–5.0% typical, depending on the target formulation and texture. |
| Best Phase | Water phase or cool-down phase (below 40°C) |
| pH Compatibility | Works best in formulations with a pH of 4.0–7.0. |
| Temperature Tolerance | Stable under typical formulation temperatures. For best results, add below 40°C to avoid degradation. |
| Pro Tip | For products targeting hair detangling, use higher concentrations (around 2.0–3.0%) to improve manageability. In skin care, lower concentrations (0.5–1.0%) are typically sufficient to provide smoothness and hydration without a greasy feel. Test your product’s sensory feel after adding Polyquat 7 to ensure the texture remains as desired, especially when used in combination with other conditioning agents. |
| Appearance | Clear, colorless to pale yellow liquid |
| Stability Notes | Stable in a wide range of formulations but can sometimes reduce viscosity in high electrolyte systems. Test compatibility in your formula before scaling up. |
