WHAT ARE PETROLEUM
DISTILLATES?
Defining "petroleum distillates" is much like trying to define
"liquids", because they can be many different things. Everyone may
have a different mental image of a "liquid". Petroleum distillates
are liquids, but so are water, whiskey, pancake syrup, eye drops,
mercury, battery acid and motor oil. They all fall into the
general category of liquids – yet they are all different. The
liquids listed above have one thing in common – each of them has a
distinct area of use where they are beneficial and effective. This
same analogy applies to petroleum distillates, so let’s examine
them in greater depth.

Some people are
mystified by the name itself “petroleum distillates”, but that is
exactly what they are – products made from crude oil that have
been distilled in a refinery and then usually processed further
and purified in some manner. The word petroleum, derived from the
Latin petra and oleum, literally means "rock oil" and refers to
hydrocarbons that occur in sedimentary rocks of the Earth's crust.
Because most people mistakenly believe that all petroleum
distillates must be similar, they find it hard to believe that
there are so many totally different types, many with completely
opposite characteristics and uses. In fact, even the term
"distillate" raises concerns in some minds. Yet, lots of common
and very beneficial things are distilled – water is distilled to
eliminate impurities and alcohol is distilled from fermented
sugars. The list could go on and on, but the point is that
distillation is neither good nor bad, just a tool to make
something more useful.
THE DISTILLATION
PROCESS
Distillation is still the basic process used to separate and
purify the components of crude oil. The type and source of the
crude oil heavily influences the resulting by-products. Crude oil
is a complex mixture of hydrocarbons with impurities like sulfur,
nitrogen and small amounts of metal. It is found throughout the
world and varies greatly in content and composition. There are
thousands of types, varying from a nearly clear liquid with the
consistency of kerosene, to a solid (at room temperature) that
looks like brown candle wax and, of course, the heavy black tarry
kind that is usually what the general public visualizes when
thinking of crude oil.
The most primary
function of an oil refinery is distillation – i.e., the oil is
heated in a large closed vessel (usually called a still). The
lighter components boil off first and rise to a higher point
inside a tower above the still. The heavier components boil off at
higher temperatures and condense back into liquids more quickly.
These products are captured on trays at each level and pass out of
the tower. The lighter and more volatile products are used in
gasoline or as solvents, the next heavier might be used as diesel
or stove oil and the next as lubricants, and so forth. Frequently,
the leftover crude is then subjected to more processing (typically
catalytic and thermal cracking) in which many more compounds are
formed and then separated again by distillation. The amount of
product distilled from crude is dependent on its characteristics.
Some crudes will yield over 90% distillates while other may yield
fewer than 20%.

RESULTS OF
DISTILLATION
The nice thing about petroleum distillate is that the distillation
process leaves behind most of the heavy black residue (like
asphalt) that can’t be boiled off as well as other undesirable
components. As you may know, gasoline is a typical petroleum
distillate as are kerosene and mineral spirits. Yet, so are motor
oil, cutting oils and the base oil of many greases.
The distilled or
purified portion of crude oil usually contains three general
classes of compounds, aromatic, naphthenic and paraffinic
hydrocarbons.
-
Aromatics are great
solvents and a base for many types of useful compounds. They are
a perfect ingredient for making such things carburetor cleaner
or a tar remover where strong solvency is needed.
-
Naphthenics (AKA
cycloparaffins) are used to make light oils, solvents and even
as a base for things like detergents and paint dryers.
-
Paraffinic compounds
have much less solvency and usually are purified further. They
are used in a myriad of consumer products, such as a coating for
milk cartons and as ingredients in many lotions and skin creams.
Crystal clear white oils are used as a laxative, to coat pans in
bakeries and as a base for medicines. Paraffinic compounds are
perfect for use as a component in automotive waxes and polishes
and those products used to treat painted surfaces, vinyl and
plastic for reasons to be discussed later.
All of these products
started as a distillate of petroleum but ended up being as
different as night and day. This is because petroleum distillates
can be further purified, re-distilled, reacted and combined with
various other chemicals to produce a wide range of useful
products.
PRODUCT LABELING
REQUIREMENTS
Any product that contains a petroleum distillate in its formula
must be labeled with the phrase "contains petroleum distillates"
regardless of the actual properties of the distillate used. The
reason for this is labeling requirements mandated by the Consumer
Product Safety Commission, a government agency. The disclosure on
a container containing low viscosity petroleum distillates is
usually preceded by a Caution or Warning statement. The warning is
provided to help doctors and emergency medical personnel
understand how best to treat children or others who might
accidentally drink the product. Child safety is a common concern
when storing any of the thousands of products that may be found in
your garage, laundry room, or under your kitchen or bathroom sink,
whether they contain a petroleum distillate or other ingredients.
If a product contains petroleum distillates, the medical personnel
may elect not to induce vomiting. The only reason that petroleum
distillate appears on the label of products is because of this
concern for children and the government regulation that mandates
it. The warning has nothing to do with product performance. In my
opinion, the label's directions for use and other cautions are
more informative for this purpose.

BENEFICIAL RESULTS
FOR APPEARANCE
The reason that petroleum distillates are used in most appearance
care products is because they perform many different and
important functions at an affordable price. Over 90% of the
thousands of paste and liquid Car Waxes and Polishes formulated
today contain significant amounts of petroleum distillate, from
the best known brands to the lesser known, as well as the highly
regarded premium quality brands used by professional detailers. It
is used in these products because petroleum distillates easily
dissolve waxes and silicones and become an excellent medium to
allow them to be spread on a surface. They also cut quickly
through oily dirt and light grease and helps lubricate the surface
and prevent scratching.
Products that are used
on plastic, vinyl and rubber surfaces should be formulated from
very special types of petroleum distillate that contain little if
any of the harsher aromatic and naphthenic molecules. While this
type of highly refined paraffinic distillate costs a good deal
more, it helps insure that the product does not attack the surface
or remove important components from the vinyl or rubber when used
as directed -- yet, it does help to clean and lubricate the
surface. Such products can be formulated to leave behind a rich
and protective film of wax or silicone (or both) to help lengthen
the useful life of the surface and prevent cracking and shrinkage.
The use of petroleum distillate allows premium UV Blockers to be
included in the formulation as the most effective ones are not
soluble in water. This can provide excellent protection against
deterioration, chalking and fading caused by sunlight.
A COMMON SENSE
DECISION
To sum it all up, there are a huge number of products available on
the market today that contain petroleum distillates. The fact that
they contain petroleum distillates doesn’t tell you much about the
product’s performance. Even for someone like myself who has been
involved with formulating specialty products for forty years,
without the complete formula I can’t determine product quality. I
do know that the majority of manufacturers today do their homework
in product development and quality control. From a business
standpoint it would not be prudent for them to do otherwise.
However, I am suspicious of companies and products that rely on
negative advertising, rather than selling their product on its own
merits. Therefore, I rely on the manufacturer’s reputation and
especially on recommendations from other users when judging what
product to buy for the first time and then by my own experience
after I’ve used it.
