Lipsticks Production

Lipstick Molding is done at specific temperatures to eliminate certain unwanted products of fast cooling (sometimes called “cold marks”).
Lipsticks liquid that is heated to around 80 C is poured into vertical split molds that are kept at temperature of around 35 C.
To prevent formation of air bubbles in the molds, We often use slightly tilted molds or use vacuuming to forcefully extract any air.
The finished product is held at a lower temperature before being poured into moulds and cooled to solidify.
The sticks may be “flamed” to produce a glossy finish to the surface. Resulting lipstick is cooled down, extracted from the molds and prepared for flaming (passing of the sticks near one or several open flame torches that will meltsmall layer of gloss around lipsticks).
This procedure will ensure better visual appearance of the lipstick, and protection from outside air and influences (lipsticks can become rancid after prolonged exposure to air, moisture and heat).
