Your position:Home > PRODUCT > Polyglycerol series
A: Product Name: four polyglycerol
Two: English Name: Four polyglycerol
Three: molecular formula, that is molecular weight: C12H26O9 314
Four: CAS:56090-54-1
Five: physical and chemical properties:
Colorless to yellowish viscous liquid. The boiling point is 265-270 (2.0kPa), 225 (0.4kPa), and the relative density is 1.2774 (20/20). The refractive index is 1.4890. Soluble in water and ethanol, insoluble in ether. Water absorption.
Six: use: polymerization glycerin than glycerol viscosity and boiling point is high, volatility and hygroscopicity is small, moisture retention is good, and has the characteristics of improving emulsion stability. It has the following uses:
(1) cosmetic raw materials (using their moisture absorption, moisture retention)
Polyglycerol is used to make milk fat and emulsion, and can be used as thickener in toothpaste. Polymerization of glycerol propylene oxide adduct is a high-quality hair cosmetic raw materials, in the higher requirement for the security field, can replace petroleum chemicals (aliphatic alcohol ether, can be used as a shampoo and conditioner; two benzophenone derivatives for ultraviolet absorption; two yuan salt or ester used as emulsifier, detergent. )
(2) fiber industry
The fiber is immersed in aqueous solution of polyglycerol and other compounds, which can improve the surface flexibility and hydrophilicity of hydrophobic fiber, and can be used as dyeing aids for water insoluble dyes.
(3) plastics industry
It can be used as nylon plasticizer, hydroxypropyl cellulose plasticizer and polyurethane plasticizer. In addition, it is expected to be a plasticizer for PVA and gelatin, and a plasticizer for semi permeable membranes.
In addition, polyglycerol is used as antistatic agent and stabilizer in synthetic resin, adding polyglycerol in dextrin, calcium chloride and gelatin, and adding glycerin glycerin borate in starch paste can adjust curing time and improve storage stability. It is also expected to be used in hot-melt adhesives. Polymerization of glycerol propylene oxide adduct can be used as oil defoaming agent, ethyl carbamate (polyurethane) materials, heavy nitrogen use copypaper slurry imaging agent and accelerator, but also can be used as formaldehyde stabilizer, gas chromatography stationary liquid used, can improve the plating quality with chemical plating liquid, on cement can prevent cracking and shorten the curing time.
The branched chain polyglycerol modified polysiloxane, not only has low irritation, low yellowing, low viscosity of polysiloxane and the inherent characteristics of high hydrophilicity, high lubricity, high ductility, but also on the various substrate wetting and adsorption is also very good, widely used in cosmetics and fiber treatment agent field.
Castor oil and polyglycerol can be used as a defoaming agent in the fermentation process, which has good effect on the elimination and inhibition of fermentation broth.
The composite grinding aids of cement can be prepared by using polyglycerol as the main body, so as to increase the output and reduce the energy consumption. It can also be used as one of the components of multifunctional composite concrete slag admixture, which improves the compactness of concrete and has the properties of anti freezing and melting.
It can also be used in latex paint, ball point pen ink, oral health care products and so on.
