Formulating with Rheozan® SH
• It is recommended to pre-mix Rheozan® SH with glycerin, glycols and similar materials for easier
dispersion and to avoid agglomeration. Add this premix to the water phase of your formulation and
mix until Rheozan® SH is completely hydrated.
• No pH adjustment is necessary.
• Rheozan® SH is suitable for both hot and cold processes.
• Rheozan® SH is also recommended to improve the skin feel of oil-in-water formulations. A dosage
of 0.2% is typically enough to provide a smooth, velvet after-feel to o/w formulations.
