DESCRIPTION

Stearyl Tartrate is a tartrate ester formed by esterifying tartaric acid with stearyl alcohol, and Stearyl Tartrate typically behaves as a lipophilic functional additive in oil-rich systems.
Stearyl Tartrate is commonly supplied as a waxy solid, flakes, or pellets, and Stearyl Tartrate is typically melted into the oil phase to achieve uniform distribution.
Stearyl Tartrate supports dispersion by improving wetting of pigments and powders, and Stearyl Tartrate can reduce hard agglomerates that cause gritty sensory feel.

Stearyl Tartrate can support water-in-oil emulsions by strengthening interfacial films, and Stearyl Tartrate can complement other emulsifiers to improve stability.
Stearyl Tartrate performance depends on raw material quality, esterification profile, and processing conditions, so formulation screening is recommended.
Stearyl Tartrate is generally used at low levels relative to the total oil phase, and optimization helps balance stability, viscosity, and sensory properties.

Stearyl Tartrate should be stored in tightly closed containers in a cool, dry place away from excessive heat and strong oxidizers.
Stearyl Tartrate should be protected from moisture contamination and strong odors because waxy materials can absorb odors.
Stearyl Tartrate should be used according to supplier specifications and applicable regulations for the intended product category and market.

Stearyl Tartrate is an ester formed from stearyl alcohol and tartaric acid and is used as a lipophilic emulsifier and dispersing aid.
Stearyl Tartrate is typically a waxy solid with strong oil solubility and low water solubility.
Stearyl Tartrate is used mainly in fat-continuous and oil-rich systems where water-in-oil stabilization is needed.

FIRST AID

Inhalation:
Move to fresh air if dust or heated fumes are inhaled.
Seek medical attention if respiratory irritation persists.
Avoid breathing aerosols during hot handling.

Skin Contact:
Wash with soap and water after contact.
For molten material contact, cool the area with water and seek medical attention for burns.
Remove contaminated clothing and wash before reuse.

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.
No specific antidote is required.
Provide supportive care as needed.

HANDLING AND STORAGE

Handling:
Use appropriate PPE including gloves and safety glasses, especially when handling molten material.
Avoid splashing into eyes and avoid prolonged skin contact with hot product.
Wash hands after handling and before eating, drinking, or smoking.

Ventilation:
Use general ventilation for normal handling.
Use local exhaust if heated processing generates fumes or aerosols.
Avoid aerosol formation in enclosed spaces without adequate airflow.

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

Spill and Leak Procedures:
For solids, collect spilled material and clean residues to prevent slip hazards.
For molten spills, allow to cool and solidify, then remove mechanically.
Dispose of waste according to local regulations and facility procedures.

Handling Precautions:
Melt and disperse Stearyl Tartrate properly in the oil phase to achieve uniform pigment wetting and stable texture.
Optimize dosage because excessive Stearyl Tartrate can over-structure the oil phase and increase viscosity beyond the target.
Validate stability and sensory performance with testing because Stearyl Tartrate effectiveness depends on oil polarity, wax system, and pigment load.
