NIKKOL BS-4

Generic name
Polyoxyethylene Stearyl Ether (4E.O.)
  • Emulsifier
    Polyoxyethylene Alkyl Ether

Ether-type nonionic surfactant manufactured by addition polymerization of ethylene oxide to stearyl alcohol. When used as a co-emulsifier in combination with a hydrophilic surfactant, more stable emulsions can be prepared. It may be easier to use than stearyl alcohol, especially in less oil systems. This product is stable against acid and alkali.

Surfactant

NIKKOL PBC-34

Hydrophilic, block-type nonionic surfactant manufactured by addition polymerization of ethylene oxide and propylene oxide to cetanol. It is widely used as a solubilizer. It has excellent salt and temperature resistance.

Oily Ingredient

NIKKOL Triester F-810

Triglyceride of glycerin and capric/capric acid. It is a light feeling oil with excellent oxidation and hydrolysis stability. It has high polarity and is effective in dissolving drugs. Compared to edible fats and oils, it is less oily and has better digestion and absorption in the body.

Surfactant

NIKKOL WAX-230

Nonionic self-emulsifying wax consisting of polyoxyethylene (20) arachidyl ether and stearyl alcohol. By mixing 5-10%, emulsions with lamellar liquid crystal structure similar to intercellular lipids in skin can be prepared. The water retained in the liquid crystal structure enhances water retention capacity of the skin.
