7. FORMULATION OF EYELINERS
LIQUID EYELINERS
It is a suspension of pigments in base containing film forming materials.
FILM FORMING MATERIALS: PVP(Polyvinyl pyrolidone)
GMS, Diethylene glycol monostearate: make applications smooth and increase
viscosity.
Surfactant: enhance spreading properties and even application. Eg., SLS
Glycerin: making film smooth and prevent drying out
Magnesium aluminium silicate: adjust volume of pigment
OTHER INGREDIENTS
Pigment
Lanolin
Water
Preservative
8. PREPARATION OF LIQUID EYELINERS
Disperse Mg aluminium silicate in a part of water to
produce suspension
Dissolve PVP in it and heat it gently
Add above mixture to the molten stearate and lanolin
Dissolve preservatives in glycerin and disperse pigments,
add dispersed pigments to above mixtures
Finally dissolve SLS in small quantity of water and mix

21. PROCEDURE
(A) firstly, heating and dissolving beeswax, candelilla wax, stearic acid, and
sorbitan monostearate to the temperature between 85 to 90° C.;
(B) secondly, heating and dissolving, or dispersing ion-exchanged water, methyl
paraben, propylene glycol, 2-amino-2-methyl-1-propanol, and pigment (black
iron oxide) to the temperature between 85 to 90° C.;
(C) thirdly, mixing (A) and (B), dispersing the mixture with the use of a
homomixer, and then cooling by agitating to 40° C.;
(D) fourthly, adding polyvinyl pyrrolidone and the alkyl acrylate-vinyl acetate
copolymer which are peliminarily disoluted in water to (C); and
(E) mixing the (D) until it becomes homogeneous.
