SHORT DESCRIPTION

Polyglyceryl Extra Pure refers to a high-purity class of non-ionic surfactants and emulsifiers derived from glycerol units. These compounds are widely used in cosmetics, pharmaceuticals, and food formulations due to their excellent skin compatibility, emulsifying properties, and biodegradability.

Polyglyceryls come in various forms (e.g., Polyglyceryl-3, Polyglyceryl-6, Polyglyceryl-10), each offering different levels of hydrophilicity and emulsifying strength. In cosmetics, they help create stable oil-in-water emulsions, ideal for lotions, creams, cleansers, and sunscreens. In pharmaceuticals, their non-toxic and non-irritating nature makes them suitable carriers for active ingredients. In food products, they function as safe emulsifiers and stabilizers, supporting clean-label and natural product development.

This extra pure grade ensures low impurity levels, minimal odor, and consistent performance, making it ideal for sensitive applications. Store tightly sealed in a cool, dry place away from heat and light to maintain its stability and quality.

Description

USES

Table of Contents

Primary Uses

Cosmetic & Personal Care Industry:
- Used as a mild, non-ionic emulsifier in skincare and haircare products.
- Common in natural and organic formulations due to its biodegradability and plant-derived origin.
- Helps stabilize oil-in-water emulsions in lotions, serums, creams, and sunscreens.
- Provides skin-conditioning effects and improves spreadability of cosmetic formulations.
Food Industry:
- When food-grade, it serves as an emulsifying agent in baked goods, sauces, and confectionery.
- Enhances texture, shelf-life, and prevents phase separation in emulsified food systems.

Secondary Uses

Pharmaceutical Industry:
- Acts as an emulsion stabilizer in topical ointments and creams.
- Used in drug delivery systems to enhance dispersion of active ingredients.
Industrial Applications:
- Used in biodegradable lubricants and environmentally friendly surfactant systems.
- Suitable for formulations requiring low toxicity and high skin compatibility, such as baby care products or specialty cleaners.

SAFETY HANDLING PRECAUTIONS

SAFETY PRECAUTIONS

Personal Protective Equipment (PPE):

Wear chemical-resistant gloves (e.g., nitrile or neoprene).
Use protective safety goggles or face shield to prevent eye exposure.
Wear a laboratory coat or protective apron.
Use a dust mask or respirator if handling powdered form in poorly ventilated areas.

Handling:

Avoid contact with eyes and prolonged skin exposure.
Prevent inhalation of dust or mist.
Handle in a well-ventilated environment.
Practice proper hygiene after handling.

Storage:

Store in a tightly sealed container.
Keep in a cool, dry place away from direct sunlight.
Avoid exposure to strong oxidizing agents or strong acids.

🚑 FIRST AID MEASURES

Inhalation:

Move to fresh air.
Seek medical attention if symptoms such as coughing, headache, or dizziness occur.

Skin Contact:

Rinse skin with soap and water.
Remove contaminated clothing.
Get medical advice if irritation or rash develops.

Eye Contact:

Rinse thoroughly with water for at least 15 minutes.
Keep eyelids open and remove contact lenses if present.
Seek medical attention if irritation persists.

Ingestion:

Rinse mouth with water.
Do not induce vomiting unless directed by a medical professional.
Seek medical help if symptoms appear.

🔥 FIRE FIGHTING MEASURES

Flammability:

Generally not highly flammable but may support combustion at high temperatures.

Extinguishing Media:

Use water spray, dry chemical, foam, or carbon dioxide.

Hazardous Combustion Products:

May produce carbon monoxide (CO), carbon dioxide (CO₂), and irritating organic vapors.

Firefighter Protection:

Firefighters should wear full protective clothing and self-contained breathing apparatus (SCBA).
Avoid inhaling vapors or smoke from combustion.
