Innovative formula

What is hydroxypropyl starch?

Hydroxypropyl Starch (PHPS) is a vegan plant‑based starch derived from non‑GMO corn, potato, cassava, and other plant sources through a controlled chemical modification process. The introduction of hydroxypropyl groups into the starch molecular structure enhances its solubility, flexibility, and film‑forming properties – making it an ideal material for plant‑based softgel capsule shells.

Unlike gelatin, which is derived from animal by‑products, PHPS is 100% plant‑based, allergen‑free, and compliant with vegan, halal, and kosher dietary requirements.

Technical Advantage

Our technological advantages

Batch Consistency

China‘s first fully automatic hydroxypropyl starch production line ensures complete batch‑to‑batch consistency, with stable viscosity, transparency, and gelation behavior across every batch.

Crystal Clear Shell

PHPS‑based capsule shells offer exceptional clarity and a premium look that surpasses gelatin and other plant alternatives – perfect for beauty brands pursuing a luxurious aesthetic.

Cost-effectiveness

The gel yield ratio reaches up to 1:3.6. The gel solution remains stable for 24 hours after melting, and waste gel can be fully recovered and reused – significantly reducing unit production costs.

Customized Formula

Pure starch gel and blended plant‑based gel. Custom formulations co‑developed with our R&D team to meet your needs.

Production process

7-step gel melting and pellet pressing process (about 4 hours)

Weighing ratio

Ingredients: Water: Glycerol
= 
1:(1.3-1.5)：(0.3-0.5)

Water oil cold mixing

Add purified water and glycerol, begin stirring. After 3 minutes, withdraw 20% of the blend from the tank bottom and reserve

Feeding

Feed raw materials steadily into the gel melting tank. Rinse the stirrer and tank walls with the reserved water‑oil blend

Heating adhesive glue

Jacket at 110°C, tank set to 102°C. Start heating. When the tank reaches 90°C, hold for 90–120 minutes

Room temperature stirring

Stir at ambient temperature for 10–15 minutes to ensure uniform gel consistency.

Primary vacuum

Jacket at 102°C. Vacuum for 1–3 min to degas the gel solution

Secondary vacuum & Encapsulation

40–60 min after primary vacuum: adjust jacket to 92°C, stop stirring, vacuum for 1–3 min. Gel is ready for encapsulation
