Product description

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

Key benefits:

• Efficiently thickens aqueous, emulsion and hydro-alcoholic systems.
• Improves emulsion stability, reduces phase separation and sedimentation.
• Forms a smooth, non-sticky film on skin and hair; supports sensorial properties.
• Thermoreversible gelation facilitates processing (adjustable texture when hot/cold).
• Good salt tolerance and compatibility with other hydrophilic polymers.
• Plant origin, non-GMO; wide range of viscosity grades available.

Suitable for products such as:

• Face and body gels, facial toners (including those with alcohol content)
• Creamy emulsions (O/W, W/O) and milks
• Shampoos, conditioners, styling products
• Cleansing foams and wash gels
• Masks, bath products, disinfecting/hygienic 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) – stabilization of the aqueous phase: 0,1 – 0,5 %.
• Foaming cleansing products: 0,2 – 0,8 % for viscosity and foam control.

Processing tips:

• To prevent lumps, predisperse the powder in glycerin/propylene glycol or slowly sprinkle it into cold water (“rain-in”) under intensive stirring and allow it to fully hydrate. The powder can also be mixed with alcohol and water then added gradually. 
• Compatible with most anionic, amphoteric and non-ionic surfactants; at high salt levels viscosity may decrease (test accordingly).
• It is recommended to add it during the cooling phase (at a temperature below 40 °C).

Safety and storage

The material is commonly used in cosmetics and skin care preparations and is generally considered well tolerated. When handling, minimize dust formation and use standard protective equipment. Preserve aqueous solutions/gels with a suitable preservative system. Store in the original, properly closed container, in a dry place and away from sources of heat and moisture.
