Product description

Hydroxypropyl Methyl Cellulose (HPMC) is a multifunctional plant cellulose derivative used as a thickener, stabilizer, film-former and rheology-modifier. It forms clear and transparent films and is characterized by thermoreversible gelation, which helps fine-tune the processing and texture of formulations. It is salt tolerant and available in a wide range of low to high viscosity grades for precise viscosity adjustment.

Key benefits:

• Effectively thickens aqueous, emulsion and hydro-alcohol systems.
• Improves the stability of emulsions, limits separation and sedimentation.
• Forms a smooth, non-sticky film on skin and hair; promotes sensoriality.
• Thermoreversible gelation facilitates processing (adjustable texture on heat/cool).
• Good salt tolerance and compatibility with other hydrophilic polymers.
• Vegetable origin, non-GMO; wide range of viscosity grades available.

Suitable for products such as:

• Face and body gels, skin tonics (including those containing alcohol)
• Creamy emulsions (O/V, V/O) and lotions
• Shampoos, conditioners, styling products
• Cleansing foams and washing gels
• Masks, bath products, disinfectant/hygiene gels

Use in formulation

Dosage (indicative according to target viscosity):

• Aqueous gels and serums: 0.3-1.0% (low to medium viscosity), 0.8-2.0% (higher viscosity).
• Emulsions (O/W) - aqueous phase stabilisation: 0,1 - 0,5 %.
• Foaming cleaning products: 0,2 - 0,8 % for viscosity and foaming control.

Technology tips:

• To avoid lumps, pre-spray powder in glycerine/propylene glycol or slowly soak in cold water ("rain-in") with vigorous stirring, allow to fully hydrate. You can also mix the powder with alcohol and gradually fart the water.
• Compatible with most anionic, amphoteric and non-ionic surfactants; viscosity may decrease with high salt doses (test).
• Recommended to add during cooling (at temperatures below 40 °C).

Safety and storage

The material is commonly used in cosmetics and skin preparations, it is generally considered to be well tolerated. Minimise dustiness and use normal protective plasters when handling. Preserve aqueous solutions/gels with a suitable preservative system. Store in the original, properly sealed container, dry and away from sources of heat and moisture.
