High stability against oxidation Liquid at 0 °C
Very good solubility characteristics
MIGLYOL® 840 is soluble at 20 °C in the following solvents:
Hexane, toluene, diethyl ether, ethyl acetate, acetone, isopropanol, and ethanol 96%. MIGLYOL® 840 is miscible in all ratios with paraffin hydrocarbons and natural oils.
Excellent spreadability on the skin and good skin absorption. Does not inhibit skin-respiration. Excellent penetration-promoting, emollient and skin-smoothing properties. Very good solubility characteristics.
Skin Care Cosmetics
Creams and lotions Non-greasy emollient oil components with medium spreadability.
Compared with petrolatum and mineral oil They are skin-permeable, do not obstruct natural skin respiration.
Skin, face and baby oils Non-oxidizing, penetration-enhancing lipid bases.
Massage oils Low-viscosity oil bases with excellent spreadability.
Masks Emollient skin care additives.
Decorative Cosmetic
Make-Up, sticks, mascara Dispersing oil component, compatible with pigments.
Makeup remover Disperses pigments and acts as a solubilizer.
Cleansing Cosmetics
Two-phase foam baths Fat component, readily miscible with natural oils and surfactants.
