Hydroxypropyl starch ether (HPS)
TENESSY - A Reliable HPS Supplier in China
Hydroxypropyl starch ether (HPS) is an ionic starch ether produced from natural polymeric material—starch—through a series of chemical and physical reactions under alkaline conditions. Hydroxypropyl starch ether is an odorless, irregular flake or white powder that dissolves in cold water to form a transparent or translucent viscous liquid.
It exhibits properties such as thickening, binding, dispersing, emulsifying, suspending, adsorbing, surface activity, and moisture retention.

Aplicaciones of HPS in Construction Materials
Dry Mix Mortar
Key Benefits
- Water Retention – Slows down moisture evaporation to keep the mortar workable for longer.
- Thickening – Enhances mortar viscosity and makes it easier to apply.
- Sag Resistance – Prevents the mortar from sliding or sagging during vertical application.
Benefits of HPS in Drymix Mortar
- Prevents cracking and strength loss caused by rapid water evaporation.
- Extends the mortar’s “open time” for easier application.
- Enhances adhesion between mortar and substrate, reducing hollowing.
Adhesivo para baldosas
-
Water Retention – Ensures complete hydration of cement.
-
Thickening and Thixotropy – Controls the flow of the adhesive, making it easy to apply while staying stable on the wall.
- Prevents tile adhesive from “drying shrinkage” due to rapid moisture absorption by tiles, avoiding tile detachment.
- Improves anti-slip performance, making it ideal for installing large-format tiles without sliding.
Interior Wall Putty
Key Benefits
- Thickening – Improves application performance, making the putty smoother to spread.
- Water Retention Prevents the putty from drying too quickly and cracking.
- Film Formation – Enhances surface smoothness for a better finish.
Benefits of HPS in Tile Adhesive
- Reduces powder shedding during putty application.
- Extends working time for smoother, more even application.
- Improves adhesion to the wall, minimizing the risk of peeling or flaking over time.
Gypsum Mortar / Putty
Key Functions:
- Set Retardation – Slows down gypsum setting for better workability.
- Water Retention & Thickening – Maintains moisture and improves consistency for easier application.
Main Benefits:
- Extends the working time, solving the problem of a short application time caused by rapid setting.
- Reduces shrinkage cracks after hardening and enhances strength.
Aplicaciones of HPS in Household and Personal Care
Skincare Products
Aplicaciones: Lotions, creams, serums, face masks, etc.
Functions:
- Thickening & Suspension: Keeps the texture smooth and prevents active ingredients (like plant particles or vitamins) from settling.
- Water Retention: Forms a light, breathable film on the skin to reduce moisture loss and support hydration.
- Gentleness: Less irritating for sensitive skin compared to synthetic polymers like carbomers.
Shampoo & Hair Care Products
Aplicaciones: Shampoo, conditioner, hair masks, styling gels, etc.
Functions:
- Shampoo: Increases thickness, improves foam stability, and reduces hair friction.
- Hair Care Products: Smooths hair, forms a protective layer, reduces frizz, and helps style last longer.
Other Personal Care Products
- Toothpaste: Thickens and improves brushing experience.
- Body Wash: Enhances texture and stabilizes foam for a better feel.
Applications of HPS in Other Industries
- Industria textil – Used as sizing paste for yarns or as printing paste for fabrics.
- Perforación petrolífera – Added to drilling fluids to improve performance.
- Paper Industry – Used as a wet-end additive or surface sizing agent to enhance paper quality.
Packaging & Storage
- The product is packed in plastic-coated polypropylene woven bags, each weighing 25 kg.
- During storage and transport, protect from sunlight, rain, and moisture.
