Water-soluble and non-ionic cellulose ether is called hydroxypropyl methylcellulose (HPMC). It provides a range of useful qualities in personal care and mortar products. HPMC products are extensively used in a variety of construction fields, including tile adhesives, grouts, EIFS, masonry mortars, repair mortars, waterproofing mortars, flooring compounds, skim coat/wall putty, gypsum-based materials, detergents, etc. because of their excellent qualities of thickening, water retention, adhesion, dispersion, suspension, surface activity, and film formation.

Please read this post, Top 7 Things You Need to Know to Buy HPMC for Tile Adhesive, if you would want more information on buying HPMC for tile adhesive.
- Solubility in cold water. The easy dissolution of HPMC in cold water shortens the waiting period.
- The thickness. enhances the stability and viscosity of liquids.
- retention of water. Increasing the open time also facilitates more thorough cement hydration.
- Greasing. Cement can benefit from HPMC for better workability and processing.
- stability of pH. MelacollTM HPMC is stable between pH 3 and pH 11.
- not ionic. In an aqueous solution, it is more stable.
- thermal condensation. When the temperature rises too high, HPMC gels and then returns to liquid form when it cools.
- Air entraining. For mortar, HPMC enhances workability and boosts output.
formation of a film. Oil and water resistant, Hydroxy Propyl Methyl Cellulose is both.
