What is Musk xylene

**Introduction to Musk Xylene** Musk xylene is a synthetic nitro musk fragrance widely used in perfumery and personal care products for its warm, woody, and animalic aroma. As one of the earliest synthetic musks, it provides a cost-effective alternative to natural musk, enhancing the longevity and depth of scents in soaps, detergents, and fine fragrances. Its robust and persistent character makes it a popular base note in floral and oriental compositions. However, due to environmental and health concerns, its use has been restricted in some regions. Despite this, musk xylene remains valued in certain applications for its distinctive, long-lasting scent profile and affordability. (Word count: 100) Let me know if you'd like any modifications!

Preparation Process: Musk xylene (2,4,6-trinitro-1,3-dimethyl-5-tert-butylbenzene) is prepared through nitration of 1,3-dimethyl-5-tert-butylbenzene (m-xylene derivative). The process involves: 1. **Nitration**: The starting material is dissolved in concentrated sulfuric acid and cooled to 0–5°C. A mixture of concentrated nitric acid and sulfuric acid is slowly added while maintaining the temperature below 10°C to prevent over-nitration. 2. **Reaction Completion**: The mixture is stirred for several hours, allowing complete nitration. 3. **Workup**: The product is poured onto ice, filtered, washed with water, and recrystallized from ethanol to yield pure musk xylene as pale yellow crystals. Proper safety measures are essential due to explosive hazards.

Usage Scenarios: Musk xylene is a synthetic nitro musk compound primarily used as a fragrance ingredient in personal care and household products, such as perfumes, soaps, detergents, and cosmetics. It imparts a long-lasting, musky scent and enhances the stability of fragrance blends. Due to its low cost and strong odor, it has been widely used in the fragrance industry. However, concerns over its environmental persistence, bioaccumulation, and potential toxicity have led to restrictions in some regions. Musk xylene is also studied for its presence in wastewater and its ecological impact, as it can accumulate in aquatic organisms and sediments. Alternatives are increasingly favored for safety.

General advice

Consult a physician. Show this safety data sheet to the doctor in attendance.

If inhaled

If breathed in, move person into fresh air. If not breathing, give artificial respiration. Consult a physician.

In case of skin contact

Wash off with soap and plenty of water. Consult a physician.

In case of eye contact

Rinse thoroughly with plenty of water for at least 15 minutes and consult a physician.

If swallowed

Never give anything by mouth to an unconscious person. Rinse mouth with water. Consult a physician.

4.2 Most important symptoms/effects, acute and delayed

Excerpt from ERG Guide 149 [Substances (Self-Reactive)]: Inhalation or contact with vapors, substance or decomposition products may cause severe injury or death. May produce irritating, toxic and/or corrosive gases. Runoff from fire control may cause pollution. (ERG, 2016)

4.3 Indication of immediate medical attention and special treatment needed, if necessary

/SRP:/ Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Aromatic hydrocarbons and related compounds/

5.Fire-fighting measures

5.1 Extinguishing media

Suitable extinguishing media

If material on fire or involved in fire: Use water in flooding quantities as fog. Solid streams of water may spread fire. Use foam, dry chemical, or carbon dioxide. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Keep run-off water out of sewers and water sources.

5.2 Specific hazards arising from the chemical

Excerpt from ERG Guide 149 [Substances (Self-Reactive)]: Self-decomposition, self-polymerization, or self-ignition may be triggered by heat, chemical reaction, friction or impact. May be ignited by heat, sparks or flames. Some may decompose explosively when heated or involved in a fire. Those substances designated with a (P) may polymerize explosively when heated or involved in a fire. May burn violently. Decomposition or polymerization may be self-accelerating and produce large amounts of gases. Vapors or dust may form explosive mixtures with air. (ERG, 2016)

5.3 Special protective actions for fire-fighters

Wear self-contained breathing apparatus for firefighting if necessary.

6.Accidental release measures

6.1 Personal precautions, protective equipment and emergency procedures

Use personal protective equipment. Avoid dust formation. Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Evacuate personnel to safe areas. Avoid breathing dust. For personal protection see section 8.

6.2 Environmental precautions

Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Discharge into the environment must be avoided.

6.3 Methods and materials for containment and cleaning up

SRP: Wastewater from contaminant suppression, cleaning of protective clothing/equipment, or contaminated sites should be contained and evaluated for subject chemical or decomposition product concentrations. Concentrations shall be lower than applicable environmental discharge or disposal criteria. Alternatively, pretreatment and/or discharge to a POTW is acceptable only after review by the governing authority. Due consideration shall be given to remediation worker exposure (inhalation, dermal and ingestion) as well as fate during treatment, transfer and disposal. If it is not practicable to manage the chemical in this fashion, it must meet Hazardous Material Criteria for disposal.

7.Handling and storage

12.Ecological information

12.1 Toxicity

  • Toxicity to fish: no data available
  • Toxicity to daphnia and other aquatic invertebrates: no data available
  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: Musk xylene, present at 100 mg/L, reached 2% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI I test(1).

12.3 Bioaccumulative potential

A BCF of 1,600 was measured in fish for musk xylene using bluegill sunfish (Lepomis macrochirus) which were exposed over a 16-day period(1) to water concentrations from 5 to 47 ug/L. Bioconcentration factors of 1,400-6,740 and 640-5,820 were measured for musk xylene in fish in flow-through tests using carp (Cyprinus carpio) with a 10 week uptake period and water concentrations of 1 ug/L and 10 ug/L respectively(2). A BCF of 3,250-6,810 was measured in fish for musk xylene using carp (Cyprinus carpio) which were exposed over a 12 week period to a water concentration of 1 ug/L(3). According to a classification scheme(4), these BCF values suggest the potential for bioconcentration in aquatic organisms is very high, provided the compound is not metabolized by the organism(SRC).

12.4 Mobility in soil

The Koc of musk xylene is estimated as 6,300(SRC), using a log Kow of 4.4(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that Mysk xylene is expected to be immobile in soil.
