Hydrocarbon Dry Clean Methods and Benefits

Hydrocarbon dry clean methods offer a gentler alternative to traditional perc-based cleaning. This is due to the lower surface tension of hydrocarbons, which allows for better penetration and removal of stains.

Hydrocarbon dry clean solvents are generally safer for people and the environment. They have a lower toxicity and are less likely to cause skin irritation.

One of the key benefits of hydrocarbon dry clean methods is the reduced risk of damage to delicate fabrics. This is especially important for cleaning sensitive items like silk, wool, and leather.

Hydrocarbon dry clean solvents can be reused multiple times, making them a more cost-effective option in the long run.

Hydrocarbon dry cleaning has gained popularity as a greener alternative to traditional Perc-based cleaning. This method utilises hydrocarbon solvents derived from crude oil, which are less toxic and environmentally harmful than Perc.

The process of hydrocarbon dry cleaning is similar to other methods, involving immersion, agitation, and drying. The dry cleaning solvents used are typically recycled, reducing waste and environmental impact.

Here are some key benefits of hydrocarbon dry cleaning:

Liquid carbon dioxide is a gentle cleaning agent that's clear, colorless, and odor-free. It's used in a process called liquid carbon dioxide cleaning, where clothes and textiles are cleaned in a bath of carbon dioxide under high pressure.

This high pressure keeps the CO2 in its liquid form, making it a unique cleaning solution. Less than 1% of cleaners in the U.S. use liquid CO2, which is surprising given its eco-friendly reputation.

Liquid CO2 is particularly good at cleaning beads, sequins, trims, and adhesives without causing damage. It's also used to remove odors from fabrics by absorbing them without harming the fabric.

However, liquid CO2 is the least effective cleaning agent for removing stains, soil, greases, and oils. This might be a drawback for some people, but it's worth noting that it's still a viable option for delicate or special-care items.

The technology behind liquid CO2 cleaning was one of several eco-friendly entrants into the drycleaning solvent market in the early 2000s. Unfortunately, it hasn't gained wide popularity due to high machine costs, lack of cleaning effectiveness, and lack of unified support by any vendor or supplier.

Choosing the right cleaning service can be overwhelming, especially with the various methods available. Petrol wash, perchloroethylene, and hydrocarbon dry cleaning are three common options.

Petrol wash is a traditional method that has been around for a while, but it may not be the best choice for delicate fabrics. Hydrocarbon dry cleaning, on the other hand, is a gentler approach that's suitable for silk and wool.

If you have heavily stained items, perchloroethylene (Perc) might be the way to go. It's known for its stain-busting power, but it's not the most environmentally friendly option.

Consider your environmental impact when choosing a cleaning service. Hydrocarbon and other eco-friendly methods are becoming increasingly accessible, giving you the option to make a more sustainable choice without sacrificing cleaning quality.

Here are some key differences between the methods:

Ultimately, the right cleaning service for you will depend on your specific needs and priorities.

Modified alcohol solvents are a popular choice for dry cleaning, providing excellent cleaning results with less aggression on beads, sequins, trims, and adhesives. They're also generally safe for most garments and other textiles.

Some dry cleaners are switching to alternative solvents due to environmental regulations and concerns about perchloroethylene's effects on human health and the environment. PERC can irritate the skin, depress the central nervous system, damage the liver and kidneys, and is a potential human carcinogen.

Aliphatic hydrocarbon solvents, such as White Spirit or Varsol, are another option, but they can leave fabric feeling very dry and may have a strong smell.

Perchloroethylene (Perc) is a clear, colorless, non-flammable liquid with a distinctive ether-like smell.

It's used by roughly 60% of cleaners in the U.S., making it a widely used solvent in the industry.

Perc is also known as Tetrachloroethylene, a name that gives you a hint about its chemical composition.

Its widespread use is a testament to its effectiveness as a cleaning agent, but it's worth noting its potential drawbacks.

Modified alcohol solvents are a colorless liquid with a mild odor.

They contain hydrocarbon and are known for providing excellent cleaning results.

Modified alcohol solvents are less aggressive on beads, sequins, trims, and adhesives than perchloroethylene.

They are generally safe for most garments and other textiles.

For added safety information, be sure to check out the Material Data Safety Sheet (MSDS) for modified alcohol solvent.

Liquid carbon dioxide cleaning is a unique process that uses high pressure to keep CO2 in its liquid form, making it clear, colorless, and odor-free. This solvent is used by less than 1% of cleaners in the U.S.

It's very gentle on beads, sequins, trims, and adhesives, but unfortunately, it's not the most effective cleaning agent for removing stains, soil, greases, and oils. This makes it less desirable for many cleaning tasks.

Finding a dry cleaner that uses liquid carbon dioxide can be a challenge due to the high machine costs and lack of unified support from vendors and suppliers. Virtually no one is working with CO2 anymore, which limits its availability.

For safety information, be sure to check out the Material Data Safety Sheet (MSDS) for liquid carbon dioxide, as it's essential to know the proper handling and precautions when working with this solvent.

Aliphatic Solvents are a type of dry cleaning solvent.

They can be found in concentrations up to 100% and vary in color from clear to yellowish-green.

White spirit, mineral spirits, Stoddard solvent, petroleum naphtha, and coal naphtha are names for this substance.

Some commonly known trade names are White Spirit or Varsol.

This type of dry cleaning fluid alone will leave the fabric feeling very dry because dry cleaners often add scented oils, which can mask the odor of formaldehyde.

With some brands using petroleum-based products, the smell of paraffin wax is also present during dry cleaning.

Hydrocarbon dry clean solvents are less aggressive on beads, sequins, trims, and adhesives than perchloroethylene.

About 30% of cleaners in the U.S. use hydrocarbon solvents.

Hydrocarbon solvents are safer for most garments and other textiles than perc, but they can negatively impact indoor air quality and the environment.

They are a VOC (Volatile Organic Compound) that can form ozone and fine particulates in the atmosphere.

Perc is an excellent cleaning agent that dissolves greases and oils very well.

Hydrocarbon solvents, on the other hand, are less aggressive on beads, sequins, trims, and adhesives than perchloroethylene, and are generally safer for most garments and other textiles.

They are also less flammable than the old-school solvents due to their higher flashpoint.

We obtained a neat sample of DF-2000 from the manufacturer.

The bulk samples of SolvonK4 were collected from a dry cleaning machine reservoir in shop A and an unused bulk sample from shop B.

We stored the SolvonK4 samples in 40 mL glass vials and kept them on ice until analyzed.

For analysis, we used gas chromatography with mass spectrometry (GC-MS) and flame ionization detection (GC-FID).

The butanol content in SolvonK4 was measured using NIOSH Method 1401,

and the formaldehyde content was measured using OSHA Method 52.

We compared our bulk analysis to a commercial butylal standard (TCI America, Lot# FIE01, purity 98%) to determine butylal content.

This helped us verify the accuracy of our measurements.

The results of the study are quite interesting. Personal full-shift air samples from dry cleaning shops using DF-2000 showed that the main tasks that led to the highest exposures were unloading and loading, with concentrations ranging from 0.99 to 5.4 mg/m.

The area air sampling results showed that full-shift area concentrations of DF-2000 ranged from 0.16–5.6 mg/m, with the highest concentrations measured in the area closest to the dry cleaning machine. Short-term area air concentrations for DF-2000 ranged from 5.3–37 mg/m.

Task-based personal exposures to DF-2000 and butylal were higher than those measured during the full shift. The highest task-based exposures to DF-2000 were measured when the owner/operator was closest to the dry cleaning machine, with concentrations up to 7.9 mg/m.

Butylal concentrations in the area air sampling ranged from 0.0039–0.31 ppm, with the highest concentrations also measured in the area closest to the dry cleaning machine. Formaldehyde was detected in one full-shift personal sample at 0.0087 ppm, which is lower than the NIOSH recommended exposure limit of 0.016 ppm.

Here are the occupational exposure limits for DF-2000 and butylal:

Butanol concentrations were not detected in any of the area air samples, and butanol was not detected (<0.001 ppm) in personal full-shift air samples.
