What is Span 85?

Span 85 is not a solitary substance, but a combination of numerous comparable make-ups, with sorbitol as the main body. It has low thickness and also the tiniest HLB worth, so it has the greatest lipophilicity. It is a superb water-in-oil (w/O) emulsifier as well as an O/w kind auxiliary emulsifier.

Span 85 Uses

  1. Span 85 is utilized as emulsifier, solubilizer and rust prevention in pharmaceuticals, cosmetics, textiles, paints, petroleum items, and also oil removal.
  2. Span 85 is utilized as an emulsifier, lubricating substance, moistening representative, dispersant, thickener, etc.
  3. Span85 has been used in research to develop a new bottom-up process for the production of protein- and peptide-containing nanoparticles for HFA propellants in suspension chemicals. It has also been used to investigate the application of analytical liquid chromatography in polymer nonionic antistatic additives.

Span 85 production Method

Put 1 mol of sorbitol into the response kettle, after vacuuming and also dehydration, the preheated refined oleic acid is poured into the pot, and the quantity of oleic acid included is 3 mol, and then a suitable quantity of sodium hydroxide is included as a driver. After that, the temperature was progressively raised to regarding 210 ° C under vacuum, and the response was maintained for 8 h. Sampling and also measuring the acid value of 14-15 mgKOH/g esterification reaction was completed. After representing stratification, the lower layer fluid is thrown out, as well as the upper layer liquid is poured into a decolorizing pot.

Application of Span 85

Spans emulsifiers can be used as emulsifiers when preparing creams, emulsions and ointments. When used alone, they can prepare stable water-in-oil emulsions or microemulsions; if used in combination with different proportions of hydrophilic emulsifiers, Tween , then various water-in-oil, oil-in-water emulsions or creams can be prepared; it can also be used as a solubilizer, wetting agent, dispersant, suspending agent, etc. It can be used to prepare inhalants, intramuscular injections, oral liquids, ophthalmic preparations, topical preparations and vaginal preparations. Medicinal Span 85 is an excellent non-ionic surfactant, which can be used as emulsifier, solubilizer, suspension agent, moisturizing agent, etc. It is widely used in the pharmaceutical industry.

Span 85 has been used as emulsifier, solubilizer, suspending agent and lubricant in aerosol, liniment, injection, ointment and other dosage forms in China. The literature points out that surfactants can act as protective agents and stabilizers in suspensions, and non-ionic surfactants with an HLB value of less than 10 are the most effective. Span 85 is the most commonly used liquid that can be dissolved or dispersed in the liquid phase. The concentration is 0.25~1% of the total weight, and it is also useful to more than 5%. In a British patent for the manufacture of medical powder aerosols, it is stated that the suspension powder is insoluble and well dispersed in a mixture of liquefied propellant and a liquid non-ionic surfactant, among the 38 formulations listed 36 use Span series, of which 33 use Span 85 (prescriptions contain hydrocortisone, phenylephrine, etc.) In the aerosol formulations such as glycerol, guaiacol glycerol ether), sodium cromoglycate, chlorpheniramine, hexylamine, ethoxycoumarin, triple bacterin, etc. It is also widely used in Shanghai, Chongqing, Wuxi and other pharmaceutical factories. As a valve system lubricant, it has low friction resistance and quick spring recovery. It is far better than using mineral oil in the valve with less residue and less odor. It does not affect the color of the aerosol and improves the amount after spraying. After comparison, Span 85 is better than Span-80 (both have a certain anti-rust effect on the spring). Wuxi Pharmaceutical No. 1 Factory used Span 85 as a solubilizer for burn aerosol and burn liniment to increase the solubility of chlorhexidine acetate in sesame oil. Compared with Span-80, it has good solubilization performance and low viscosity. The finished product Transparent, easy to filter and use.

For the emulsion droplets prepared by Span 85, 95% of the oil droplets have a particle size of less than 5μ. Some fat-soluble vitamins, such as A, D, and E, are often formulated into oil injections. If you want to prepare aqueous injections or aqueous suspension injections, dispersants must be added. Such as Span-85, it has the effect of solubilizing the micelles of the main drug. The Vidin glue calcium injection in Jiangsu, Guangdong and Zhejiang contains Span-85 0.22% and Tween-80 0.88%. For stability test, after 4000rPm for 15 minutes, there is no delamination phenomenon. The disc 85 can increase the solubility and release of the drug in the ointment base and reduce the viscosity. It is also used in tablet coating formulations abroad, and has anti-humidity and other effects. Span series have been used as food additives in Japan and other countries, used in ice cream, bread, cakes, chocolate, throwing sugar, etc. as emulsifier and dispersant, as stabilizer and suspending agent for emulsified food, and also as a dispersant. Foaming agent.

The Production of Span 85 in Various Aspects

CN201810861427.9 discloses a slurry for recycled yarn sizing and a preparation method thereof, belonging to the technical field of the textile industry. The present invention adopts raw materials: starch, cowhide cream, sodium peroxide, sodium chloride, dicyandiamide, oleate, sorbitan trioleate, polyoxyethylene sorbitan monostearate, dodecyl Sodium benzenesulfonate and distilled water; first put the distilled water into the mixing bucket, turn on the mixer, then put in oleate, Span 85, polyoxyethylene sorbitan monostearate and stir evenly, then put in Leather paste, sodium chloride, dicyandiamide and sodium dodecyl benzene sulfonate and stir evenly, then add starch and stir evenly, then heat and simmer.
