trying recipes is nice but formulating the and knowing what and why things are happening make all the difference..  knowing why the bond are interacting and the chemical bond that are  forming is another ..

If wrong someone correct  me shelf life depend on the life span of the oils. i think if one of your oil have  a shelf life of 7 month and one 12 that would cut down life span….
 Chime in @Bobzchemist

yes i agree. Does anyone remember the 80’s and rancid lipstick smell lol..
thank god to antioxidant to prolong this issue and preserves.. to avoid that white yuk that forms <span>:blush:</span>

I agree with ozgirl. learning the HLB system and it rules is essential .. also adding polysorbate 80 if you want to emulsify some of that oil so not to leave such a greasy feel. it all depend what you want.
I am a nurse and took chemistry course outside of what was needed. 
you need to decide whether you want an emulsified or not.
here is a powerful PDF you can learn and memorize. http://www.scientificspectator.com/documents/personal%20care%20spectator/HLB_Basics.pdf&nbsp;

also when mixing with bases. you may have an issue mixing oxides with them.
my work around is a silicone and denatured alcohol blend which I mix with my oxides. this will prevent any lumps and granulation that may occur.

another tip  for matte polish ( which i don’t recommend as it tends to chip faster than using the matte over coat) is adding nylon or fumed silica .. this in itself can create a matte over coat or polish.. you can also add scent to your polish bases. ( again pointless since the scent wears off quickly)..  
you can also add kaolin clay to create a harder base.. 
hope this is helpful

I agree I have my bases in a room with good ventilation.. opted to by bases. instead of creating my own.. the fumes are horrible. 
bases can be sold at several Artisan store online. do a search for glamour polish  base etc. or franken polish. also Manufacturers will sell their base at gallon pricing if you meet there min amount. otherwise they may charge you a fee.

I had friend that gave me the chemicals need.. I tried this at home.. even though i was successful the fumes are horrid..  changed my mind completely.  I do am interested. in what chemical i can use to add more of an plasticy film. to make polish last longer. basically making a tad bit ore rubbery without compromising the adherence 

[Zolveria]

 >  lmao.. the things we go through.. 

[Zolveria]

thanks.. the silica i use for matte. I entering the wonderful world of volatiles now reading paint chemistry

[Zolveria]

LMAO  I had a person say some they are Diabetic and cant use a sugar scrub LMAO… I had to look at her.. Since she was a Nurse.. and that made no sense. 
SmH.. she wanted me to make one with salt  SMH.. i felt like telling her ummm wont that raise your BP … the things i go through

[Zolveria]

sorry for the late response. : I am a Nurse Full time and CC partime.
So here the break down:
Below these increase translucence 

Zinc Stearate, Magnesium mysterate, Magnesium stearate, Rice powder, Corn powder, Silk

SLIP AND ADHESION: Magnesium Stearate, Rice powder, Silk  magnesium myristate koalin.

opacifier : Titanium dioxide, Kaolin, Silk mica, Satin pearl

There maybe more.. Bob should know..

[Zolveria]

okay this is a binding issue.. 
why did u add the alcohol. when i mix my mica and oxides i use my base and adhesion level choice in mind. i then mix everything except my micas. I then add my pressing medium.. until it look like wet sand. then press…and let them sit to dry.

[Zolveria]

a good place to get bases is essential by catalina .. the vitamin a c and e is wonderfull and can be used in several facial application with some tweeking

[Zolveria]

you can use a coffee grinder or a old mill.
also never grind your effects mica this will damage them..

make your base illuminator, bronzere etc

Corn Powder / rice powder etcc 30%
Sericite mica or treated sericite 30%
Magnesium Mystearate 30%
Sericite with Lauroyl-lysine 5%
mica effect 5%

mix all these and press with some
Isopropyl Myristate,
D5 or Dimethicone, Bis-Vinyl Dimethicone/Dimethicone Copolymer mixture
remeber all must equal 100
to the press you use enough to wet the mica not to saturate it..
press and leave out to dry..

you can also use a mortor to grind.. but i find that a grinder works best in these handmade situations.

they carry this product 

[Zolveria]

I grind in my grinder and disperse in castor, octyldecanol etc. and let them sit for a while. for my lipstick i use castor oil and disperse my colorants in that.. i dont use these for a while as they sit …  after a  month they are not lump but nice creamy  paste. SADLY a grinding mill is what we need. something the chemist have in there labs….  

[Zolveria]

Matte lipstick need silicones oils and gels. I use silica and nylon 12 i also add kaolin or maiz starch..  along with hectorite gel. and then some nourshing oils. this depending on what i want. 
know the percetage of each needed to form a stick or liquid form i think some where around here there are percentages. for each thickener , emmoilliant etc. 
silicone add slip and glide and also dry.. coconut oils ( tryglycerides can also be used. since they are drying oil.. 
hope this helps.. again.. looing in the right place..
ultraspector, special chem for cosmetic, lubrizol etc. looking at formulas and understanding why they are using each chemical oil etc.. 

[Zolveria]

Im not a degree chemist but as far as i have understood. silicones give the dry feel.

also  try  BENTONE GEL = bentonite

HERE  a link to http://cosmeticssciencecenter.com/  

LOOK up thickeners. he explains all of this.. 

Here is anothe link on here

not sure i have read on these topic for several years now  these things.. if anyone can chime in with more knowledge this would be helpful

____________________________________________________________________________

also have you read the formulation bookd cosmetic and toiletries. I have all the volumes..  I can look in my books and see what I can find. as a starting point.

also special chem has tons of information on all chemicals cosmetic

http://www.makingcosmetics.com/Glycolic-Acid_p_1100.html
for small home production they also see pails. hopes this helpss

[Zolveria]

Yes no degree. here in US just chemistry degree which cover most of what a chemist needs to know. then learning to formulate for the cosmetic industry through trial and error many notes.. and knowledge of each product and what they can do….DUPONT TATE AND LYLE  has nice video covering esters, wax etc  http://www.cosmeticssciencecenter.com/
