METHYLCELLULOSE
APPLICATIONS
The lather enhancement, thickening,
lubricity
and surfactant properties of
METHYLCELLULOSE
products are all important
in the
formulation of a host of bath
products.
And in every case, the product
improvements
are made with economy since very
small concentrations
are required.
Liquid Hand Soaps
METHYLCELLULOSE products
provide bulk viscosity with
excellent efficiency while
promoting
high sudsing action in liquid
hand
soaps. The natural lubricity afforded
by
the polymer contributes a
pleasant
and rich sensation during use.
Bubble Baths/Shower Gels
Just as in
shampoos, METHYLCELLULOSE products
add
to the texture of the thickened
liquid,
and then go on to provide
a superior
volume of lubricious lather.
METHYLCELLULOSE
products help generate
stable
lathers. And nowhere is lather
longevity
more important than in a
bubble
bath. Also important is the
ability
to reduce or eliminate lather
stabilizers
that may be irritating to those
with
sensitive skin, especially children.
The widespread use of METHYLCELLULOSE
products
in hair care formulations is
ample
testimony to their recognized
versatility.
Virtually every property of
these
unique cellulosics is called upon
to
some degree in these applications.
Shampoos
Today’s hair
care products increasingly
require
raw materials that are safe and
effective
while addressing multiple
needs.
METHYLCELLULOSE polymers are used
in
shampoos both as a thickener and
lather
enhancer.
Minimize surfactant usage/maximize
mildness
Small concentrations of
METHYLCELLULOSE can replace greater
amounts of salt and
surfactant while
maintaining desired
product
viscosity. Minimizing surfactant
content
will yield a milder formulation
that
often is desired for products with
frequent
usage. The savings in surfactant
may
offset the cost of the METHYLCELLULOSE.
Enhance lather characteristics
Through a unique property—interfacial
gelation—METHYLCELLULOSE products are the
only polymeric thickeners that actually
contribute to increased foam stability
at shampooing temperatures. Compared
to other common cellulosic polymers,
METHYLCELLULOSE also produces a greater
foam volume.
Interfacial
gelation is the formation
of polymer
networks at air/water interfaces when a dilute solution
of
METHYLCELLULOSE is heated. In a shampoo,
an
interfacial gel of concentrated polymer
forms
between and around bubbles. This
gel
structure thickens and reinforces
bubble
walls and slows the rate at which
water
can drain away. Bubble walls do
not
thin out and disintegrate as rapidly.
Skin Care Products
In skin care
products, METHYLCELLULOSE
products
are used for thickening, lather
enhancement,
lubricity, and emulsification.
The
combination of these properties
can
result in subtle, but important,
improvements
in product quality.
Moisturizing Creams and Lotions
When used as a
secondary thickener
with xanthan gum
or carbomer in moisturizing
creams
and lotions, METHYLCELLULOSE
makes
additional contributions
to the
texture of the product
and the
quality of its after feel. Two
properties
are key. First is the natural
lubricity of dissolved
METHYLCELLULOSE. This is most
noticeable
in the flow and feel of lotions
and
creams. Products have a smoother,
softer
feel during application. There is
less
"drag" and the product takes a little
longer
to absorb, heightening the sensation
of
moisturization. Second is the
surface activity
of METHYLCELLULOSE
ethers. These polymeric surfactants
can be used to impart stability to
cosmetic emulsions.
METHYLCELLULOSE
products possess HLB values in the range
of
10 –12.
Shave Creams and Gels
Though primarily
used as thickeners
and lather
enhancement agents,
METHYLCELLULOSE
products also add
the moisture
retention and lubricity
desired in
shaving preparations. Lathers
are
dense, moisture-rich, long lasting
and
provide excellent razor glide.
Facial Cleansers, Masks, Toners
The
contributions of METHYLCELLULOSE to
cleansing lotions, scrubs, and liquid
soaps
are many. As in shampoos,
METHYLCELLULOSE
serves to thicken
and enhance lather
volume and stability.
As in
moisturizing creams and
lotions, the
film-forming properties
of
METHYLCELLULOSE products help provide
a
silky, non-greasy sensation during
application.
When used in facial masks the
thickening
and film-forming properties
of
METHYLCELLULOSE products are key. They
enable
uniform application resulting
in a
quick drying film. When used in
toner
and antiseptic skin cleansers,
METHYLCELLULOSE
provides an exceptional
non-greasy,
silky smooth sensation during
application.
It is compatible with
both aqueous
and hydro-alcoholic
formulations
Deodorants/antiperspirants
Besides
thickening some roll-on deodorant
formulations,
METHYLCELLULOSE products
add
film-forming characteristics and ease
of
application.
BLENDING METHYLCELLULOSE INTO YOUR FORMULATION
Blending Shampoos
The methylcellulose we provide is cold water soluble.
1. Disperse the methylcellulose in the water
portion of your formulation. The pH of this solution must be below 7.5. Use Citric
acid if necessary to adjust pH. This is generally a very small amount.
It helps to disperse the Methylcellulose in hot water if possible.
2. After the material is thoroughly dispersed
adjust the pH back above 8.0 using Triethanolamine.
(any alkali can be used but we recommend this) The amount of Triethanolamine
used is about equal to the amount of methylcellulose that you use. Mix
well for 15 to 20 minutes until fully thickened.
3. Add all your other ingredients. Adjust the pH
back again to near 7.0.
If you are using components that require heat, heat the methylcellulose/water
solution at this point and add your ingredients.
