Definition
Mixed monolayers of 1-octadecanol and ethylene glycol monooctadecyl ether were studied to investigate their evaporation suppressing performance.
The rate dependence of the collapse pressure for an octadecanolmonolayer using axisymmetric drop shape analysis has been investigated.

Application
EMERCOL C18 99 MY is a long chain primary alcohol that is used in the production of emulsions, textile oils, antifoam agents, and lubricants.
Other large scale applications include the manufacture of alkyl amines, tertiary amines, ethoxylates, halides/mercaptans, and polymerization stabilizers.
EMERCOL C18 99 MY generally occurs as a mixture of solid alcohols whose primary constituent is 1-octadecanol.
EMERCOL C18 99 MY occurs naturally in sperm whale oil and has been isolated from the hyperthermophilic bacterium Pyrococcus furiosus.
EMERCOL C18 99 MY has been used to model the plant epicuticular wax layer for an investigation by differential scanning calorimetry and Fourier transform infrared spectroscopy.
The use of EMERCOL C18 99 MY to prepare microsphere formulations for such compounds as paclitaxel and indomethacin has been described.
EMERCOL C18 99 MY is used to surfactant in cosmetics.
EMERCOL C18 99 MY provides effective hydration to hands and face with pheohydrane which is a complex of the mico algae Chlorella Vulgaris and hydrolysed algin in a sea water base.
EMERCOL C18 99 MY is a saturated alcohol of high purity and can substitute for cetyl alcohol in pharmaceutical dispensing, in cosmetic creams, for emulsions, textile oils and finishes, as antifoam agent, lubricant, viscosity agent, builder, and chemical raw material.
EMERCOL C18 99 MY is used as a component in lubricants and resins.
EMERCOL C18 99 MY is also used as an emulsifier and thickener.
Pharmaceutical Applications
EMERCOL C18 99 MY is used in cosmetics and topical pharmaceutical creams and ointments as a stiffening agent.
By increasing the viscosity of an emulsion, stearyl alcohol increases its stability.
EMERCOL C18 99 MY also has some emollient and weak emulsifying properties, and is used to increase the water-holding capacity of ointments, e.g. petrolatum.
In addition, EMERCOL C18 99 MY has been used in controlled-release tablets, suppositories, and microspheres.
EMERCOL C18 99 MY has also been investigated for use as a transdermal penetration enhancer.
Production Methods
Historically, EMERCOL C18 99 MY was prepared from sperm whale oil but is now largely prepared synthetically by reduction of ethyl stearate with lithium aluminum hydride.
