DESCRIPTION

Polyglycerol Polyricinoleate is a polymeric ester made from polyglycerol and polymerized ricinoleic acid, and the resulting structure provides strong interfacial activity in fat-rich environments.
Polyglycerol Polyricinoleate is primarily a water-in-oil emulsifier, and Polyglycerol Polyricinoleate stabilizes small water droplets dispersed in fat, reducing coalescence and improving stability.
Polyglycerol Polyricinoleate can reduce chocolate yield stress by modifying particle-particle interactions and lubrication in the fat phase, which improves flow without excessive fat addition.

Polyglycerol Polyricinoleate is often used alongside lecithin, and the combination can optimize viscosity reduction and processing performance across different chocolate types.
Polyglycerol Polyricinoleate performance depends on dosage and fat composition, and excessive Polyglycerol Polyricinoleate can affect mouthfeel, so optimization is important.
Polyglycerol Polyricinoleate should be selected based on regulatory compliance and supplier quality parameters, including acid value, hydroxyl value, and polymer distribution.

Polyglycerol Polyricinoleate should be stored in tightly closed containers in a cool, dry place away from heat and strong odors.
Polyglycerol Polyricinoleate is typically a viscous liquid and can thicken at lower temperatures, so warming may be used for handling without overheating.
Polyglycerol Polyricinoleate should be used according to applicable food additive regulations and good manufacturing practices for the target market.

FIRST AID

Inhalation:
Move to fresh air if heated mists are inhaled.
Seek medical attention if respiratory irritation persists.
Avoid breathing aerosols during hot handling and spraying.

Skin Contact:

Seek medical advice if irritation develops or persists.

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 persists.

Ingestion:
Rinse mouth with water.
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.

HANDLING AND STORAGE

Handling:
Use appropriate PPE including gloves and safety glasses, especially during bulk handling.
Avoid splashing into eyes and avoid prolonged skin contact.
Wash hands after handling and before eating, drinking, or smoking.

Ventilation:
Use general ventilation for normal handling.
Use local exhaust if heated handling generates mists.
Avoid aerosol formation in enclosed spaces without proper ventilation.

Storage:
Store in tightly closed containers in a cool, dry place away from heat sources.
Protect from moisture contamination and strong odors because fats can absorb odors.
Keep containers properly labeled and protected from contamination.

Spill and Leak Procedures:
Contain the spill and absorb with inert material.
Clean surfaces thoroughly because oily materials can create slip hazards.
Dispose of waste according to local regulations and food industry procedures.

Handling Precautions:
Optimize dosage with testing because Polyglycerol Polyricinoleate influences chocolate rheology and excessive levels can affect mouthfeel.
Control handling temperature to maintain pumpability while avoiding overheating and degradation.
Rotate stock using FIFO practices to maintain consistent quality and predictable emulsification performance.
