MASURF EMULSIFYING WAX is a nonionic self-emulsifying wax prepared from high purity cetearyl alcohol and polysorbate 60. Monographed in the National Formulary NF XVII, MASURF EMULSIFYING WAX is the premier nonionic self-emulsifying wax used in the cosmetic and pharmaceutical industries, and is now available in a convenient pastille form.
MASURF EMULSIFYING WAX produces thick, solid emulsions without the addition of stiffening waxes at concentrations as low as 5-10%. MASURF EMULSIFYING WAX emulsions show excellent compatibility in anionic, cationic and nonionic systems, and produce stable emulsions at pH 3-13.
A mild ingredient with a proven safety record, use MASURF EMULSIFYING WAX in Creams, Lotions, Shampoos, Conditioners, Pomades, Sunscreens, Pharmaceutical Ointments, Salves, Skin Protection, Creams and other emulsions.
MASURF EMULSIFYING WAX is a non-toxic, non-irritating concentrated surfactant blend in pastillated form. Exercise normal handling precautions by using appropriate eye and skin protection. Refer to Material Safety Data Sheet.
INCI Name: Cetearyl Alcohol and Polysorbate 60.

FUNCTIONS:
In cosmetic and pharmaceutical formulations, MASURF EMULSIFYING WAX has proven to be a desirable alternative to glyceryl monostearate, diglycol stearate, propylene glycol monostearate, self-emulsifying fatty alcohol blends and other wax-like emulsifiers. MASURF EMULSIFYING WAX yields emulsions of superior stability, elegance and efficacy when substituted at equal to lower ratios for these emulsifiers. MASURF EMULSIFYING WAX offers advantages over carbomer stabilized emulsions: emulsifier/thickener in one, compatible with cationic materials, no neutralization is needed in the formulation of creams and lotions, and extremely tolerant of inorganic salts.
MASURF EMULSIFYING WAX can be used to produce viscous or thin emulsions, depending upon the concentration at which it is used. At low concentrations of 2-3%, MASURF EMULSIFYING WAX provides optimum emulsion stability supplemented with other emulsifiers. Fluid emulsions can be easily produced using MASURF EMULSIFYING WAX with any of these commonly used materials: Ethoxylated lanolin alcohols, ethoxylated fatty alcohols, sorbitan esters and ethoxylated sorbitan esters, phosphate esters, or ethoxylated lanolin.
USAGE:
MASURF EMULSIFYING WAX emulsions can be prepared easily by incorporating MASURF EMULSIFYING WAX in the oil phase and then heating it and the water phase separately to 70-80°C. Once the two phases reach this temperature, the water phase is added to the oil phase in a thin stream using mechanical agitation. The emulsion is then stirred down to a temperature above the solidification point of the cream (to 30°C for a lotion). These emulsions are very stable, easy spreading systems, but can be homogenized if desired. Utilize Enhansys™ Fortifying Enhancement Systems for self-preserving cosmetic preparations.

COSMETIC APPLICATIONS:
MASURF EMULSIFYING WAX has been used successfully in hair relaxers/straighteners for many years. Showing better stability over time than other emulsifiers, it is still the emulsifier of choice for these preparations. MASURF EMULSIFYING WAX has also been used in many types of skin care and hair care formulations and has applications as an emulsifier/thickener in products such as the following: Hair conditioners and cream rinses, Hair bleaches, Moisturizing creams and lotions, Baby lotions, Indoor and outdoor tanning preparations, Sunscreen creams and lotions, Nail creams and lotions, Night creams and lotions, Wrinkle smoothing creams and lotions (wrinkle reducers), Blushers, Eye makeup and makeup bases, Wave sets, and Hair relaxers/straighteners
PHARMACEUTICAL APPLICATIONS:
Due to its nonionic nature, MASURF EMULSIFYING WAX will not interact with ionic pharmaceutical actives. MASURF EMULSIFYING WAX creams can usually be sterilized by autoclaving. Its many pharmaceutical applications include the following: Manufacture of hydrophilic petrolatum, Antibiotic creams and lotions, Hydrocortisone creams and lotions, Acne/blemish creams and lotions, Burn and sunburn creams, lotions and mousses, External analgesic rubs, Medicated creams and lotions, Sunscreen creams, lotions and mousses, Moisturizing creams and lotions, Skin protectant creams and lotions.
