Sodium tripolyphosphate/ STPP
Industrial grade 96% CAS 7758-29-4
Food grade 85% CAS 7758-29-4
Molecular formula Na5P3O10
Molecular weight 367.86
【 Performance Characteristics 】
White granular or powder, showing a density of 0.35-0.90G/CM3,
melting point 622 degrees Celsius.
It is easily soluble in water, the aqueous solution is alkaline,
and the PH of 1% aqueous solution is 9.7.
It is gradually hydrolyzed into phosphite in water, and has good
ionic ability of metal complexation.
It can be complexed with calcium/magnesium/iron and
other metal ions to produce soluble complexes. It softens hard
water. As a kind of inorganic surfactant,
it has some properties of organic surfactant.
【 Purpose 】
Mainly used for synthetic detergent as an additive/soap agent and
to prevent bar soap grease precipitation and
frosting. It has a strong emulsifying effect on lubricating oil and
fat, and can be used to
adjust the PH value of buffer soap liquid, industrial water
softener/tanning and
pre-tanning agent/dyeing agent/paint/kaolin/magnesium oxide/calcium
carbonate and
other industries to prepare suspension as a dispersant, drilling
mud dispersant,
and paper industry as an anti-oil agent.
Market demand
Detergent industry:
Sodium tripolyphosphate is an important component in traditional
detergents and
is used as a wash aid, water softener and dispersant.
Despite the rise of environmentally friendly non-phosphorous
detergents,
phosphorus-containing detergents are still dominant in many
developing countries.
Food Industry:
As a food additive (moisture retention agent, emulsifier, buffer),
sodium tripolyphosphate has a steady demand in processed foods such
as meat, seafood, and dairy products.
Water treatment:
In water treatment, sodium tripolyphosphate is used as a water
softener and
corrosion inhibitor, and the market demand is growing with the
increase of industrial water demand.
Ceramics and paper industry:
In the ceramic and paper industry, sodium tripolyphosphate is used
as a dispersant and auxiliary agent,
and the market demand is stable.
Healthy Food Trends
With the rise of health foods and functional foods, the demand for
high-quality food additives has increased.
As an important food additive, food grade sodium tripolyphosphate
has a stable demand and
broad application prospect in the market.
Despite challenges such as food safety regulations and
environmental pressure,
the market potential of food-grade sodium tripolyphosphates is
still huge through technological innovation and
market expansion. Enterprises need to pay close attention to market
dynamics and
flexibly respond to market changes in order to maintain a
competitive edge.
