Lipstick bullets : scuff marks and small bubbles
Why are my 12 cavity metal plates, causing scuff marks when i remove my bullets. If i increase the wax my payoff is compromised
What are some basic troubleshooting tips..
The product is stabel, and has won beauty industry awards so far for clients. Ive tried a new plate, same outcome.
Any ideas on how to reduce this “matt” blotchy look on an otherwise shiny bullet.

Can you post a picture…. and formula?
Maybe the scuff marks….are bloom?
If it is bloom….take a look at Chemical Matt’s hack…in the following link:

For making Lipsticks it is very important that the temperature is very well controlled during the Pouring as well as the Cooling process. Otherwise, the waxes can blook or scruff marks form. The Pouring temperature depends a lot on the Recrystaliziation point of your Wax mixture. it needs to be very close to the point normally.

This is the effect. Thankyou for your comments.
If we were to assess this from a method perspective, what is the best practice for
1. Cleaning the plate or mold and 2. Is there any other preparation i can try on the metal surface prior to injecting?

I generally use IPM to dab the mold/dye if the stick does not look shiny enough. Use a cotton cloth, dip it in isopropylmyristate and swab the plate cavity, repeat after 20-25 uses.
I second @Gordof on the temperature issue. You have to be careful with that, however with the picture you have provided, I see the pigment is disturbed. Try grinding the pigment finely & maybe use a dispersing agent. Make sure there is no air bubbles while you pour the lipstick in your dye.
You may want to try pouring with a new dye too. Sometimes we use sharp objects to clean the dye, Try not to use sharp objects.

For Preperation of the Form of your lipstick you can use a Foodgrade Silicon oil spray to layer the Mattel with the silicon. that will help to get a clear surface of the stick as well

Oh great. I will try this also thankyou.

Add some highly shrinkable wax, carnauba wax, plus some low shrinkage wax, candelilla wax to balance the shrinkage effect, these waxes all have smooth surfaces.

So to update we have reduced bubbles by reducing the injection temp
We still get the scuffy bullet, i think that has somewhat improved by releasing tension off the bullet, as we push the case down, to release into packaging.
Higher ti02 content was causing more mini bubbles its an ongoing love hate still…
