POLYGLYCEROL RICINOLEATE

Polyglycerol Ricinoleate is a polyglycerol ester emulsifier used in food, cosmetics, personal care, pharmaceutical, and specialty emulsion systems, and Polyglycerol Ricinoleate is valued for strong water-in-oil emulsification, viscosity reduction, pigment wetting, and oil-phase stabilization.
Polyglycerol Ricinoleate is commonly used in chocolate, confectionery fats, spreads, low-fat emulsions, creams, lotions, sunscreens, makeup, balms, and anhydrous-to-emulsion systems where stable oil-continuous structure and smooth processing are required.
Polyglycerol Ricinoleate is typically supplied as a yellowish to amber viscous liquid or paste-like material, and Polyglycerol Ricinoleate performance depends on polyglycerol composition, ricinoleic acid ester profile, acid value, hydroxyl value, dosage, oil-phase polarity, processing temperature, and compatibility with fats, waxes, pigments, actives, and electrolytes.

DESCRIPTION

Polyglycerol Ricinoleate is a polyglycerol ester made from polyglycerol and ricinoleic acid-rich fatty acid components, and Polyglycerol Ricinoleate has both hydrophilic polyglycerol groups and hydrophobic ricinoleate chains.
Polyglycerol Ricinoleate behaves as a nonionic low-HLB emulsifier, and its amphiphilic structure supports stable water-in-oil emulsions and dispersion of polar or particulate ingredients in oil phases.
Polyglycerol Ricinoleate is widely known as PGPR in food applications and as E476 when used as a permitted food emulsifier in regulated markets.

Polyglycerol Ricinoleate reduces interfacial tension between water and oil phases, helping stabilize fine water droplets in fat-continuous or oil-continuous systems.
Polyglycerol Ricinoleate can reduce the flow resistance of chocolate and fat-based masses, which improves processing, enrobing, pumping, and molding performance.
Polyglycerol Ricinoleate can improve pigment wetting because ricinoleate ester chains interact well with oils, waxes, pigments, and hydrophobic formulation components.

Polyglycerol Ricinoleate should be evaluated in the complete formulation because electrolyte content, water-phase composition, wax level, oil polarity, fat crystallization, and processing shear can affect emulsion stability.
Polyglycerol Ricinoleate is generally stable under normal storage conditions, but Polyglycerol Ricinoleate should be protected from excessive heat, strong oxidizers, moisture contamination, and prolonged air exposure.
Polyglycerol Ricinoleate should be used according to supplier recommendations, food additive regulations, cosmetic GMP, workplace safety standards, and applicable market requirements.

FIRST AID

Inhalation:
Move to fresh air if mist, aerosol, or heated vapors are inhaled.
Seek medical attention if respiratory irritation, coughing, or discomfort persists.
Avoid breathing mist during spraying, heating, or high-shear processing.

Skin Contact:
Wash skin with soap and water after contact.
Remove contaminated clothing if necessary and wash before reuse.
Seek medical advice if irritation, redness, or prolonged discomfort develops.

Eye Contact:
Rinse cautiously with water for several minutes.
Remove contact lenses if present and easy to do, then continue rinsing.
Seek medical attention if irritation, redness, or blurred vision persists.

Ingestion:
Rinse mouth with water.
Do not induce vomiting.
Seek medical attention if discomfort occurs or if a significant amount is swallowed.
Never give anything by mouth to an unconscious person.

Note to Physicians:
Treat symptomatically.
Monitor for irritation or gastrointestinal discomfort after significant exposure.
Provide supportive care as needed.

HANDLING AND STORAGE

Handling:
Use appropriate PPE including gloves and safety glasses for bulk handling.
Avoid splashing, prolonged skin contact, and inhalation of mist or heated vapors.
Use clean, dry equipment to prevent contamination in food, cosmetic, pharmaceutical, and technical production.

Ventilation:
Use general ventilation for normal handling.
Use local exhaust ventilation where mist, aerosol, or heated vapors may be generated.
Provide adequate ventilation during heated processing or large-scale mixing.

Storage:
Store in tightly closed containers in a cool, dry, well-ventilated area.
Protect from excessive heat, direct sunlight, moisture contamination, and air oxidation.
Keep away from strong oxidizers, strong acids, strong bases, and incompatible reactive chemicals.

Spill and Leak Procedures:
Contain spill with inert absorbent and prevent entry into drains and waterways.
Collect into suitable containers for reuse or disposal according to local regulations and facility procedures.
Clean remaining residue promptly because oily emulsifier residues can create slipping hazards.

Handling Precautions:
Optimize dosage because Polyglycerol Ricinoleate affects water-in-oil stability, chocolate viscosity, flow behavior, pigment dispersion, and final product texture.
Control processing temperature and shear because emulsion stability and viscosity reduction depend on proper phase mixing, droplet size, and fat or oil compatibility.
Rotate stock using FIFO practices to maintain consistent color, odor, viscosity, acid value, and emulsification performance.
