Carboxy Methyl Cellulose (Cellulose Gum) - CMC- Food Grade

Description

Carboxy Methyl Cellulose (Cellulose Gum) - CMC- Food Grade•
Carboxymethyl Cellulose (CMC) is an odourless, tasteless white or milk-white fibrous powder that is
sometimes referred to as Cellulose Gum. CMC is used as a thickener, coating agent and natural food adhesive. When fully dissolved in water, Carboxymethyl Cellulose forms a viscous consistency depending on the amount of water added. The resulting gel is completely stable to heat, weak alkalis or acids and microorganisms.
Widely used in the food industry as a viscosity modifier or thickener and to stabilise emulsions in various products. It is a constituent o many non-food products such as toothpaste, laxatives, diet pills, water-based paints, detergents, textile sizing, various paper products and reusable heat packs to name a few.
CMC is favoured because it has a high viscosity, is non-toxic and is generally considered to be hypoallergenic. CMC also has good compatibility with other kinds of water-soluble glues, softeners and resin. For example, it is compatible with animal glues, dimethoxy dimethylurea gel, Arabic gum, pectin, tragacanth gum, ethylene glycol, sorbitol, glycerol, invert sugar, soluble starch and sodium alginate.
CMC is used in
food
under the
E number
E466 as a
viscosity
modifier or
thickener
, and to
stabilize
emulsions
in various products including
ice cream
. It is also a constituent of many non-food products, such as
personal lubricants
,
toothpaste
,
laxatives
,
diet
pills,
water
-based
paints
,
detergents
, textile
sizing
, and various
paper
products. It is used primarily because it has high
viscosity
, is nontoxic, and is generally considered to be
hypoallergenic
as the major source fiber is either softwood pulp or
cotton linter
.
CMC is used extensively in gluten free
and reduced fat food products.
In laundry detergents, it is used as a soil suspension polymer designed to deposit onto cotton and other cellulosic fabrics, creating a negatively charged barrier to soils in the wash solution. CMC is used as a
lubricant
in
artificial tears
. Sometimes
methyl cellulose
(MC) is used, but its nonpolar
methyl
groups (-CH
3
) do not add any solubility or chemical reactivity to the base cellulose.
