Hydroxypropyl Guar is a modified guar gum used to build viscosity and improve sensory in water-based formulations.
It gives a smoother, more cushioned slip than standard guar gum and can help reduce a “stringy” feel in gel textures when used correctly.
In hair care, it supports a softer feel and helps improve combability, especially in shampoos and conditioning systems.
In skincare, it can be used to improve gel texture, suspend light particles, and add a richer glide to water-based products.
FEATURES
- Natural thickening – builds viscosity in water-based systems.
- Slip enhancer – improves glide and reduces drag in gels and washes.
- Hair feel support – improves softness and combability feel in shampoos.
- Suspension help – supports particle suspension in light gel systems.
BEST FOR
- Shampoos
- Serums
- Gel cleansers
- Hair conditioning washes
- Hydrating gels
- Suspension gels
FORMULATION GUIDELINES
| INCI | Hydroxypropyl Guar |
|---|---|
| Type | Natural polymer thickener / rheology modifier |
| Solubility | Water dispersible (hydrates in water) |
| Use Rate | 0.1–1.0% typical. 0.2–0.6% is common for shampoos and body washes. 0.3–0.8% is common for gels depending on target viscosity. |
| Best Phase | Water phase (add before surfactants where possible) |
| pH Compatibility | Works across many systems. We recommend finished product pH 4.5–8.0 for stable performance. |
| Temperature Tolerance | Stable under normal processing. Hydration can be done at room temperature or with gentle warming. |
| Pro Tip | Pre-wet hydroxypropyl guar with glycerin, then add to water with good mixing to prevent clumps. Allow full hydration time before final viscosity decisions. In surfactant systems, add before salt and fragrance because electrolytes and solvents can shift viscosity and clarity. |
| Appearance | Off-white to yellow powder |
| Stability Notes | May create a slightly hazy gel depending on concentration and system. Test compatibility with electrolytes and preservatives early. |
| Storage | Keep sealed, cool and dry. Protect from humidity. |
