1.Food grade sodium carboxymethyl starch
Sodium carboxymethyl starch (CMS) is a
modified starch etherified with carboxymethyl. It is
odorless, non-toxic, not easy to
mildew, and easily soluble in water. Used
in different foods, it shows various functions such
as thickening, suspension,
emulsification, stabilization, shape
retention, film formation,
puffing, preservation, acid resistance and
health care. Best product. Food grade
sodium carboxymethyl starch is widely used in milk,
beverage, frozen food, fast food,
cake, syrup and other products. In
addition, CMS is physiologically inert and has no
calorific value, so it can also be used to make
low-calorie foods with desirable results.
2. Pharmaceutical grade sodium carboxymethyl
starch
Sodium carboxymethyl starch (CMS) is widely
used in medicine. For pharmaceutical
preparations, CMS can replace gelatin as a raw
material for making capsules, tablets, and
sugar coatings. It has strong water absorption and
swellability. It can foam quickly in cold
water, and after absorbing water, the
particles expand without dissolving, do not form a
colloidal solution, and do not hinder the continuous
infiltration of water and affect the further disintegration of
the tablet, so it can be used It is used as a
high-efficiency disintegrant and excipient for insoluble drugs
and soluble drug tablets.
3. Paper grade sodium carboxymethyl
starch
Sodium Carboxymethyl Starch (CMS) is a
modified starch etherified with carboxymethyl, which
is better than carboxymethyl cellulose (CMC)
and is the best product to replace CMC. The
application of CMS in papermaking is quite
extensive. It is added as a stabilizer in the filler
to thicken and bond, make the paper bright and
bright, improve the printing performance of the
paper, and enhance the toughness and wear resistance
of the paper. Used as an additive in pulp to improve
retention and drainage effect. It is also used for
surface sizing of paper, which can significantly
improve the dry and wet strength, oil
resistance, ink absorption and water resistance of
paper. Use in coating bonding can improve paper
production and performance.
4. Construction industry grade sodium
carboxymethyl starch
Sodium carboxymethyl starch (CMS) is a
modified starch etherified with carboxymethyl, which
is better than carboxymethyl cellulose (CMC)
and is the best product to replace CMC. The solution
has good thickening, stabilizing,
water-retaining, film-forming and suspending
effects. Easy to use, safe and
environmentally friendly. It has been widely used in
the building materials industry. It is used as a
thickening and water-retaining agent in putty powder and latex
paint; it is used as a suspending agent,
stabilizer, and film-forming agent in
coatings, and has the functions of
emulsifying, thickening, and
anti-deposition. It can be used in cement plastering
mortar, cement thermal insulation anti-cracking
mortar, tile adhesive, exterior wall
waterproof putty, and other cement-related
products.
5. Ceramic industrial grade sodium carboxymethyl
starch
Sodium carboxymethyl starch (CMS) is a
modified starch etherified with carboxymethyl, and
its performance is better than that of carboxymethyl cellulose
(CMC), which is the best product to
replace CMC. CMS is used as an excipient,
plasticizer, and reinforcing agent for blanks in the
ceramic industry. It can increase the cohesion of
the blank, make the blank easy to form,
double the flexural strength, and effectively reduce
the breakage rate of the blank; it can also make the
moisture in the blank evaporate evenly to prevent drying and
cracking. Adding it to the glaze slurry as a
stabilizer and a binder can enhance the bonding of the
glaze, make the glaze in a dispersed state,
increase the surface tension of the glaze, increase
the smoothness of the glaze, and reduce the
phenomenon of pinholes after baking.
6. Daily chemical industrial grade sodium
carboxymethyl starch
Sodium carboxymethyl starch (CMS) is a
modified starch etherified with carboxymethyl, which
is better than carboxymethyl cellulose (CMC)
and is the best product to replace CMC. CMS has the
functions of chelation, ion exchange,
polycationic flocculation, etc. It can be
used as stabilizer, fiber finishing agent and
stain-carrying agent in detergent formulations. Its
descaling effect is obviously better than that of
CMC, and its dirt diffusing ability is
excellent, especially the anti-soil re-precipitation
effect on hydrophobic synthetic fiber fabrics. In
the cosmetic industry, CMS is used as a water-fixing
or water-absorbing and water-retaining sizing material for the
manufacture of anti-acne pharmaceutical preparations and the
manufacture of skin cleansers. In
toothpaste, CMS can form a three-dimensional
polymeric network structure, which can ensure the
storage stability of the paste in the tube, prolong
the shelf life, improve the paste uniformity and
surface finish, and reduce the paste delivery
power. CMS is easily biodegradable, safe
and environmentally friendly.
7. Petroleum industry grade sodium carboxymethyl
starch
Sodium carboxymethyl starch (CMS) is a
modified starch etherified with carboxymethyl, and
its performance is better than that of carboxymethyl cellulose
(CMC), which is the best product to
replace CMC. The aqueous solution of CMS is stable
and has excellent performance, with functions such as
bonding, thickening, water
retention, emulsifying, suspending and
dispersing. CMS acts as a mud stabilizer and
water-retaining agent in the process of oil well
operation, which can reduce water loss and improve
the coalescence stability of clay particles in drilling
fluid. CMS has little effect on the plastic
viscosity of the mud, but has a large effect on the
power and shear force, which is beneficial to carry
drill cuttings, especially when drilling the
salt-gypsum layer, it can stabilize the drilling
fluid, reduce the loss, and prevent the
well wall from collapsing. It is especially suitable
for saline-alkali wells with high salinity and high PH
value.
8, printing and dyeing industrial grade sodium
carboxymethyl starch
Sodium carboxymethyl starch (CMS) is a
modified starch etherified with carboxymethyl, and
its performance is better than that of carboxymethyl cellulose
(CMC). It is the best product to
replace CMC. The aqueous solution of CMS is stable
and has excellent performance, with functions such as
bonding, thickening, water
retention, emulsifying, suspending and
dispersing. The raw material of CMS is
starch, which has a wide source and low
price. CMS for printing and dyeing is used as a
carrier paste for dyes and printing and dyeing
auxiliaries, which has the advantages of good
compatibility and stability. The dyeing paste
prepared with CMS has good permeability, especially
for the embossing of deep and transparent fabrics,
which can quickly print patterns according to the
pattern, and can significantly improve the vividness
of printing. In addition, CMS can be
dissolved in cold water, which is convenient to
use.
