What is SLES and how is it used in global industries?
It is available in 28% and 70% active
concentration.
For exports, 70% active concentration is most
preferred.
Chemistry
SLES is prepared by ethoxylation of dodecyl alcohol. The resulting ethoxylate
is converted to a half ester of sulfuric acid, which is then neutralized by
conversion to the sodium salt.
Key Benefits of SLES
The product has good solvency,
favorable hard-water resistance and high-biodegradation. It also facilitates
ease of formulation and production. In addition, it also creates a degree of
thickening to the final product formulation.
Industry Applications and End Products
It is widely used in many personal
care and home care products like Shampoo, Bubble Bath, Shower Gel, Face Wash,
Dish Wash, Liquid Detergent and Hand Wash.
It is also used in the printing and dyeing industry, petroleum and leather
industry as lubricant, dyeing agent, cleanser, foaming agent and degreasing
agent.
Innovations and Trends
SLES is a simple ingredient, used
with a singular primary purpose for the manufacturing of cosmetic and detergent
products for the mass market. In doing so, there has been no innovation or
revolutionary trend for this product since its inception.
Market Insights
The market size for SLES is expected
to surpass USD 1.5 billion by 2024. This is attributed to increasing
demand for personal care products throughout the globe, especially in
developing countries, which boost the global SLES market. Increasing
pollution and concerns about personal grooming, appearance, and health will
positively influence the global personal care market, which generated more than
USD 500 billion in 2015, and will have a decent growth rate in the coming
years. Moreover, regular development and commercialization of new personal care
products to meet specific customer demands will also bolster the global SLES
market in the forecast spell.
SLS vs SLES
Mainly found in
items that are formulated to clean our skin, teeth and clothes, sodium lauryl
sulfate (SLS) and sodium laureth sulfate (SLES) are just a few ingredients that
are added to a range of everyday products. Often confused due to their similar
names, there’s a big difference between SLS and SLES.
Both made by mixing
lauryl alcohol with sulphuric acid and adding sodium carbonate, these
sulphate compounds known as surfactants and can be found in many
soaps, toothpastes, shampoos and washing liquids that are widely available
on the high street. Surfactants mean that a little product can go a long way,
all while other ingredients work to nourish, clean and protect.
With their main use
to create the well-known foam we all know and love, these lather-creating
extras also enable the core ingredients of products such as shower gel,
toothpaste and washing liquids to be dispersed effectively across the entire
surface area.
So, what’s the difference between SLS and SLES?
While both are added to create foam and help to produce a cleaning
action, the two ingredients are very different.
Starting with sodium lauryl sulfate (SLS), this surfactant is a
great cleaning product but is well-known to be an irritant when left on the skin
for prolonged periods of time. By affecting the everyday function of skin
proteins, this leads to damage of the outer layer of skin which helps to cause
cracked, dry and tender skin.
If you suffer from comedones (more commonly known as whiteheads or blackheads),
SLS has also been identified as a key player in increasing the number of these
found on the face and body.
Additionally, SLS in shampoo and other hair products can often ‘sit’ on
hair follicles even after washing, resulting in weakening of the hair follicles
over extended periods of time.
So, sounds lovely, doesn’t it? Funnily enough, SLS is deemed as being
‘safe to use’ by many regulatory bodies such as The Cosmetic, Toiletry and
Fragrance Association (CTFA) and The Cosmetic Ingredient Review Panel (CIR). In
recent years, it has picked up a considerable amount of attention across the
internet with rumours of it being linked to cancer, however, there has been no
evidence that SLS is linked to this in any way.
One thing that’s known is that SLS can be a skin irritant when left on
for prolonged periods of time and that is one reason why we do not use it in
Bubble T products. If you do choose to use other brands that use SLS and feel
any irritation, we would strongly suggest washing it off immediately and apply
a soothing layer of SLS-free moisturiser to try to calm the skin.
Now we know a little more about SLS, sodium laureth sulfate
(SLES) is created through a process called ethoxylation (any product
ending in -eth has also been through the same process) where ethylene oxide is
added to change the makeup of the compound.
Safe to use in bath & body products, this process means SLES is much
gentler to use on both hair and skin and doesn’t strip the epidermis of any
excess moisture, leaving it feeling soft, smooth and nourished.
Here at Bubble T, we choose to stay far away from SLS and use SLES in
our shower gel, body scrub and foaming bath jelly to create the foam and lather
we all love. When mixed with ingredients such as bergamot oil, orange seed oil,
fruit extracts and tea-based infusions, SLES acts as an extremely effective
addition to these products.
One key reason for choosing to use SLES is that while other
foam-creating ingredients are out there on the market, many have been or are
being tested on animals which we fully do not believe in or condone.
On the high street, you will find SLS or SLES in many products,
including:
·
Soap
·
Shampoo
·
Body wash
·
Toothpaste
·
Washing liquid
·
Shaving cream
·
Mouthwash
·
Bubble bath
·
Moisturiser
·
Sun cream.
Overview
Sodium lauryl
sulfate (SLS) is one of the ingredients you’ll find listed on your shampoo
bottle. However, unless you’re a chemist, you likely don’t know what it is. The
chemical is found in many cleaning and beauty products, but it’s frequently
misunderstood.
Urban myths have
linked it to cancer and skin irritation and more. Science may tell a
different.

| Price Rs: 506/ |
How it works
SLS is what’s known
as a “surfactant.” This means it lowers the surface tension between
ingredients, which is why it’s used as a cleansing and foaming agent.
Most concerns about
SLS stem from the fact that it can be found in beauty and self-care products as
well as in household cleaners.
Sodium laureth
sulfate (SLES) is a surfactant with a similar chemical formula. However, SLES
is milder and less irritating than SLS.

Where you’ll find
SLS
If you look under
your bathroom sink, or on the shelf in your shower, it’s very likely you’ll
find SLS in your home. It’s used in a variety of products, including:
- Grooming products, such as shaving cream, lip
balm, hand sanitizer, nail treatments, makeup remover, foundation, facial
cleansers, exfoliants, and liquid hand soap
- Hair products, such
as shampoo conditioner, hair dye, dandraf treatment,
and styling gel.
- Dental care products, such as
toothpaste, teeth whitening product and mouthwash
- Bath products, such as bath oils or
salts, body wash, and bubble bath
- Creams and lotions, such as hand cream, masks anti-itch creams, hair-removal products, and sunscreen.
Price Rs: 209/
You’ll notice that
all of these products are topical, or applied directly to the skin or body.
SLS is also used as
a food additive usually as an emulsifier or a thickener. It can be
found in dried egg products, some marshmallow products, and certain dry beverage
bases.
Takeaway
The amount of SLS
found in your personal care products is limited in concentration. For people
who simply don’t believe that SLS is safe, or don’t want to try their luck, an
increasing number of products that don’t contain SLS are appearing on the
market.
Look for them
online or at stores by reviewing the ingredient labels.
