MIGLYOL® 818
Product Name MIGLYOL® 818
INCI Name Caprylic/Capric/Linoleic Triglyceride
Product Description
MIGLYOL® 818 MIGLYOL® 818 is a triglyceride of the fractionated plant fatty acids C8 und C10 and contains about 4 to 5 % linoleic acid. For special skin effects, triglycerides with a defined amount of double unsaturated fatty acids are used in cosmetics.
MIGLYOL® 829 MIGLYOL® 829 is a glycerin ester of the fractionated plant fatty acids C8 und C10, combined with succinic acid. The viscosity is about 230 mPa·s. Because of its high density of 1.00 – 1.02 g/cm3 MIGLYOL® 829 promotes stability in emulsions.

Applications
MIGLYOL® neutral oils are clear, virtually colourless liquids of neutral odour and taste.
MIGLYOL® neutral oils are very pure because of their carefully selected raw materials. As a result of tightly controlled manufacturing process, they contain very few microorganisms and are free of additives such as antioxidants, solvents and catalyst residues (Exception: MIGLYOL® 818, which contains an antioxidant).
High stability against oxidation (Exception: MIGLYOL® 818 contains about 4 % linoleic acid). Liquid at 0 °C
MIGLYOL® neutral oils are soluble at 20 °C in the following solvents:
Hexane, toluene, diethyl ether, ethyl acetate, acetone, isopropanol, and ethanol 96%. Neutral oils are miscible in all ratios with paraffin hydrocarbons and natural oils
Cosmetic Functions
MIGLYOL® neutral oils have the following advantages in comparison to natural oils
Excellent spreadability on the skin and good skin absorption.
Do 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.
Sunscreens
O/W sunscreen creams Oil component, compatible with organic and inorganic filter agents.
W/O sunscreen creams, sunscreen oils Water-resistant oil components, less greasy, do not obstruct skin respiration.
