Hydroxypropyl Starch Ether (HPS) Functions

Thickening Effect

Enhances viscosity for better texture and product stability.

Emulsion Stabilization

Prevents oil–water separation and extends shelf life.

Film-Forming Capability

Creates protective films, improves texture, and controls active ingredient release.

High Solubility

Dissolves easily in water-based formulations for smooth blending.

Water Retention

Locks in moisture to protect skin in cosmetics and maintain freshness in food.

HPS Specification

Celix Hydroxypropyl Starch Ether (HPS) is a highly effective additive designed to optimize the performance and cost-efficiency of dry mix mortars. One of its key advantages is the strong synergy with HPMC, where a small dosage of HPS can significantly enhance mortar rheology while allowing manufacturers to reduce the amount of HPMC required, helping lower formulation costs without sacrificing performance. Celix HPS provides excellent anti-sagging properties, effectively preventing tile slippage in tile adhesives and reducing layer sag in plastering mortars, even when applied in thicker layers. It also greatly improves workability, creating a creamy texture and smooth troweling feel that allows applicators to spread mortar effortlessly and achieve better finishing quality. In addition, Celix HPS helps reduce stickiness to tools, minimizing mortar adhesion to trowels and mixers, which improves construction efficiency and provides a cleaner, more controlled application experience. Together, these benefits make Celix HPS an ideal additive for modern dry mix mortar formulations.

FAQ About Hydroxypropyl Starch Ether

How does starch ether improve construction performance for tile adhesive and plaster mortar?

Starch ether improves the consistency and application experience of mortar. It provides a creamy texture and smooth troweling, making it easier for workers to spread the mortar evenly. At the same time, it reduces stickiness to tools, preventing mortar from sticking excessively to trowels and mixers, which improves construction efficiency and jobsite cleanliness.


Can starch ether reduce the amount of HPMC used in mortar formulations?

Yes. One of the key advantages of starch ether is its synergy with HPMC. By adding a small amount of HPS, mortar producers can significantly improve anti-sagging and rheological properties, which allows them to reduce the dosage of HPMC in the formulation. This helps manufacturers optimize production costs while maintaining high performance.
