PHPS Capsule Material

Plant-based shell material for soft capsules — supplied as PHPS powder in three grades.

PHPS pregelatinized hydroxypropyl starch in glass petri dish, beaker, and stainless-steel scoop — pharmaceutical-grade plant-based capsule material

PHPS — Pregelatinized Hydroxypropyl Starch
Plant-Based Capsule Material

Our PHPS — a dual-modified starch, chemically hydroxypropylated and physically pregelatinized — is manufactured from non-GMO corn, potato, cassava, and pea starches. ChP-listed pharmaceutical excipient, GB 29930-2013 compliant, HALAL/LPPOM-MUI certified across four countries. Supplied in 25 kg/bag powder form, PHPS is the primary shell material for plant-based soft capsules across nutritional supplements, functional gel candy, and color cosmetics — plus emerging intimate-wellness applications.

The AMYLOM™ Series — Three Powder Grades

Clear

AMYLOM™ PHPS Clear

Pure-starch grade

Pure plant-starch shell — no carrageenan, no gellan, no synthetic gelling agents.

Natural

AMYLOM™ PHPS Natural

Blended plant-gel grade

PHPS blended with carrageenan or gellan; mainstream cost-performance.

Tailor-Made

AMYLOM™ PHPS Tailor-Made

Custom-formulated PHPS

Custom shell formulas by application — for example, chewable gel candy and other specialty fills.

PHPS supports a range of end-product capsule formats: oil-based / powder fills · crystal-clear / custom-color / pearl-opaque shells · custom shape, size, and fill volume on request.

Key Advantages

  • Crystal-clear shell — premium visual quality for color cosmetics and skincare
  • Up to 1:3.6 gel yield ratio
  • Gel solution stable for 72 hours after melting
  • Custom formula and process supported per client specification
  • Compatible with rotary-cage continuous drying or tray drying

02 — Equipment

Softgel Production-Line Engineering

Purpose-built equipment for plant softgel production — designed around PHPS material properties, sized for lab to commercial scale.

Why plant softgels need specialized equipment

Plant gel has higher viscosity, weaker fluidity, weaker initial seam strength, and lower coating tensile strength than gelatin. It requires higher gel-melting and supply temperatures and is more sensitive to environmental conditions — making purpose-built equipment essential for reliable commercial production.

Equipment Line-up

Some components built in-house; others sourced from OEM partners of over a decade. Encapsulation machines and gel boxes from a Chinese OEM whose founder co-authored China’s national softgel machinery standard. Molds from a specialist holding 80%+ domestic share, shipping 2,000+ die sets annually to 30+ countries.

Built in-house

Gel-Melt Tank

  • 300–450 L, commercial production size
  • External-circulation heating for uniform temperature
  • Specialized stirring design for plant gel
  • Optional one-touch automated control

OEM partner

Compression Machine + Gel Box

  • Linear servo fill pump — fill error within ±1%
  • Self-heating gel intake pipe; adjustable airflow
  • Auto-startup self-check; automatic mold alignment
  • Spray, fill & lubrication auto-track rotation speed

OEM partner

Custom Molds

  • Unique seam-cutout geometry for stronger seaming
  • Stars, hearts, droplets, oval, oblong shapes
  • Mold precision: 0.001–0.003 mm
  • Dense layout to reduce per-unit cost
