Common Name: Eumulgin B25
Chemical Nature: Ethoxylated fatty alcohol, categorized under nonionic surfactants within the ethoxylate group.
Typical Use: Emulsifier in cosmetic formulations, personal care products, and some industrial cleaners.
Appearance: White to off-white solid, sometimes found as paste or flakes depending on the storage temperature.
Odor: Mild, characteristic of nonionic surfactants, not especially pungent.
Solubility: Readily dissolves in water, giving clear or slightly turbid solutions.
Boiling Range: Not especially defined due to the material's ethoxylate content, which modifies melting and boiling behavior.
CAS Number: Main constituents usually registered, but blends may not have a single identifier.
Health Hazards: May cause mild skin and eye irritation after contact, sensitivity may increase with prolonged or repeated exposure.
Environmental Hazards: Harmful to aquatic life at certain concentrations; surfactants can disrupt the natural balance in waterways.
Fire Hazards: Not considered highly flammable but can contribute to combustion if present with other organics.
Inhalation Risk: Low volatility minimizes respiratory exposure during typical use.
Classification: Sometimes not classified as hazardous under GHS, but site-specific risk assessments matter.
Main Component: Fatty alcohol ethoxylates, usually based on natural C16-C18 chains, ethoxylated between 25 and 50 moles.
Impurities: Unreacted alcohols, trace byproducts from ethoxylation, mainly inert from a toxicological perspective.
Concentration Range: Active substance generally over 95%.
Additives: Often free from functional additives, but preservatives may be present in some applications.
Eye Contact: Rinse thoroughly with water for several minutes; persistent irritation deserves medical attention.
Skin Contact: Wash affected area with plenty of soap and water; remove contaminated clothing.
Inhalation: Unlikely to be a problem, but move to fresh air if discomfort occurs.
Ingestion: Drink water to dilute, don’t induce vomiting, consult medical help if large amount is swallowed.
Suitable Extinguishing Media: Water spray, foam, dry powder, or carbon dioxide depending on the surrounding material.
Special Protective Equipment: Full protective clothing and self-contained breathing apparatus help in dense smoke.
Fire/Explosion Risk: Slippery spills may complicate evacuation; no major explosion risk under normal conditions.
Combustion Products: May emit carbon oxides and other irritants if fully decomposed.
Personal Precautions: Avoid skin and eye contact, wear gloves and goggles in large-scale cleanups.
Environmental Protection: Prevent undiluted product from entering storm drains or waterways.
Cleanup Methods: Absorb with inert material, place in containers for disposal; scrub area with water to reduce slipperiness.
Handling Practices: Work with good ventilation, avoid splashing, maintain basic personal hygiene.
Storage Conditions: Store in tightly closed containers, away from direct heat sources, frequently kept at moderate room temperature to avoid thickening.
Incompatibilities: Avoid mixing with strong oxidizers or strong acids.
Control Parameters: No occupational exposure limits set; focus rests more on engineering controls and safe operating procedures.
Engineering Controls: Reasonable ventilation is usually enough for normal lab or workshop scenarios.
Personal Protective Equipment: Gloves and safety goggles during transfer or bulk handling, longer sleeves if handling large volumes.
Respiratory Protection: Rarely needed unless mists or aerosols could form.
Physical State: Waxy, solid flake, or soft paste depending on ambient temperature.
Color: White to pale yellow, a sign of slight variations in feedstock origin.
Melting Range: Starts softening around 50°C.
Solubility: Easily disperses in water, yielding stable emulsions.
pH: Slightly above neutral, often 6 to 8 for 5% aqueous solutions.
Odor: Characteristic, not unpleasant nor especially strong.
Thermal Stability: Stable under recommended conditions; excessive heat can break down structure.
Reactivity: Low; doesn’t react strongly with most common laboratory chemicals.
Hazardous Decomposition: Carbon monoxide, carbon dioxide, minor traces of formaldehyde if severely overheated.
Acute Toxicity: Reports suggest low acute toxicity for humans and animals, though irritation of mucous membranes is possible with significant exposure.
Chronic Effects: Unlikely at occupational exposure levels; prolonged or repeated skin contact can lead to dryness or mild dermatitis.
Inhalation: Minimal risk if used in well-ventilated areas.
Eye/Skin Contact: May cause redness or stinging that typically resolves quickly.
Biodegradability: Designed to break down in biological systems; meets most modern standards for environmental compatibility.
Aquatic Toxicity: Adverse effects on aquatic organisms at high levels, so wastewater treatment matters.
Bioaccumulation: Not a high concern for long-chain ethoxylated alcohols.
Waste Treatment: Send to facilities that can treat surfactant-rich waste streams; avoid landfill dumping of raw product.
Incineration: Possible for dry product or after solidification, but keep volume low due to resource recovery priorities.
Sewer Disposal: Dilution and biological treatment help minimize risk in municipal systems; never pour into natural waterways.
UN Classification: Not regulated for transport over land, sea, or air due to low flammability and ecohazard under normal conditions.
Packaging: Use sealed drums or containers to prevent leakage.
Spill Management: Address leaks quickly to avoid slip hazards and local contamination.
International Regulation: Surfactants like Eumulgin B25 meet compliance for use in cosmetics and cleaning agents under frameworks such as REACH in the European Union.
Labeling Requirements: Typically require warning about eye and skin irritation.
Workplace Safety: Standard operating procedures recommend gloves and eye protection in bulk handling settings.
