I am a color cosmetics manufacturer in India. We have been making bullet lipsticks for mass market consumption for about 7 years now. Our oil phase includes Castor oil & CCTG. I have never encountered rancidity in my products however, adding TBHQ is a standard practice that we have followed since day one. If you can find that chemical, please try it. It is the best antioxidant in my experience. Hope this helps ! 

Can you plz guide when this chemical should be added i mean while melting or in the end before pouring. But i think it is difficult to find this chemical 🤕

Hi dear thank you so much for your reply. I think TBHQ is difficult to find. I am gonna add BHT in my lipsticks to avoid rancidity.

Chelators are not equal.  Like preservatives, subordinating a functional ingredient to serve a secondary claim is not without risk.  All you have to judge is a PET test too blunt to dissect that risk.  

ok dear got it. will share my experience soon with you all after testing it for sometime

Sometimes GLDA is hard to find…so I’ll include a link:

TSGD (Tetrasodium Glutamate Diacetate)-STA-TSGD-01 (makingcosmetics.com)

I like that one, because it comes as a liquid, and is one less powder I have to wonder if it went into solution.  (Since this one is only about 50% active ingredient…I would not hug the bottom end of use rate….but around .2% at least.

If you are only making for yourself…and using within a very short amount of time….you can get by without chelators.  But if you ever aspire to sell anything, might as well get used to formulating with them.

thank you so much dear for detailed guideline 🥰🥰

Graillotion said:

EDTA is a chelator….so it does not have to be exactly EDTA, there are a number of options that do about the same thing.

A more natural approach to chelating would be things like GLDA or Sodium phytate.

But yes….chelates are very important, on multiple levels.

thank you so much for helping me ,💕💕

PhilGeis said:

For preservation (booster)  - WITH a preservative.  Those are good preservative systems and EDTA enhances.

ok dear thank you so much for guidance 💕

PhilGeis said:

For preservation - yes.

and for lotion i am adding phenonip

You should check it to ensure that it’s within the compatibility range of your ingredients, and also to monitor for changes of pH over time. 

ok dear thank you so much for reply i will check it..it should b 5.5.

How much water?  Have you seen any mold or other microbial contamination?

my Lipsticks are water free. but after one year they start smells rancid my clients want more shelf life. at least 2-3 years 

Sounds like you are trying to preserve your oils… You are barking up the wrong tree with parabens…. You need to be looking at antioxidents.

ROE / E / Bisabolol / Oil soluable C….etc..etc.

i am adding vitamin e t-50 for oxidation but they smells rancid after one year. my point is how to resolve this issue so that my Lipsticks stay longer at least 2-3 years 

Combine Tocopherol with Rosemary Oleoresin. That’s what I do with a lot of my raw ingredients and some of my emulsions.

ok i will try rosemary

PhilGeis said:

Test your “rancid” product.  Unless you find contamination doubt if you need a preservative with that formula.

ok thank you so much dear for guidance 

[saraahsan]

Paprik said:

Also, add the tocopherol right before pouring it. 
Meaning, heat all ingredients, melt everything and wait as long as you can, so the temperature drops, add Toco, mix and pour. 

Let us know how it goes. 
Do you have an incubator or something? That you could do accelerated testing? 

no i dont have. yes i will experiment adding tocopherol in the end as much as temperature go down. hopefully it will work for me

cap2 preser vative - think you’re wasting your money.

ohh what do u recommend then should i complete skip any preservative?

[saraahsan]

abierose said:

Personally, if you’re wanting your lipsticks to be used for longer than a year…or two or three…I would probably include a lip-safe preservative due to the probability of moisture contamination…

yes i am adding tkb cap-2 preservative which is lip safe. just my Lipsticks smells rancid after one year. i need to experiments on antioxidant hopefully issue would be resolved then. thanks all lovely people for guidance means alot 

[saraahsan]

Paprik said:

You would need to conduct some testing to find out. 
You are adding 50% actual Tocopherol, I would definitely try to add 1% of actual Tocopherol, therefore 2% of T-50. And see how it goes.  

ok thank you so much for guidance

I am not into lipsticks and all- but just a thought- maybe switch oils / butters to the kind with a longer shelf life maybe or replace aome with eaters- along with all the other maneuvers 

i am adding castor oil plus caprylic capric 

castor oil has a shorter shelf life that most of plant butters- most of them being in the 2 years range as acompared to 1 year for the castor oil- 2 years if hydrogenated- other options are softisan 378 (fantastic for lipsticks) has a shelf life of 3 years and is soft solid at room temp

What do you mean by “shelf life”? Before going rancid? Actually Castor oil is one of the most stable oils. Together with Jojoba (which is a wax actually) and Coconut oil. It has very good oxidative stability. 

so my oils are ok its mean i ass castor oil and caprylic capric triglycerides. i should work on my antioxidant. should i add more vitamin e oil?

I dont make lipsticks, but i do make diy cleansing balms and cleansing oil for my friends and family. Water free formula.

I used to have issues like this but now my cleansing balms dont go rancid as fast. The one i made 2 years ago still smell okay.

What i did, i changed most of my plant oils to synthetic ingredients. The products mostly made of:
Caprylic capric triglyceride
Mineral oil
C12-15 Alkyl benzoate
Isododecane
Some sunflower oil and castor oil
Other plant oils (i limit to 1% max)
BHT as antioxadant at 0.1%
Fragrance and essential oils (max 0.05%)
For natural wax, i only use white beeswax

I dont use preservatives as long as the product is kept away from water and stored properly (not in the bathroom!) Never had any mold. But my “clients” are just friends and family and i always remind them to keep the products dry.

waooo thank u so much. my formula is also water free

candelila wax

carbauba wax

microcrystalline wax

cetyl alcohol 

i add castor oil and caprylic capric triglycerides equal parts 

for texture i add bit magnesium stearate and magnesium myristate 

1% vitamin e tocopherol t-50

this is my base formula

then i take the base and colourants then mix them up and fill the Lipstick mould

but my Lipsticks stays one year . should i try to add BHT instead of vitamin e? if yes bht would b added while melting all base ingredients? 

would be very grateful for ur reply 

[saraahsan]

Paprik said:

How much of the Tocopherol are using? And what type? 
I believe it’s a hot fill/pour, which will already oxidase some of the vit E, so you need to increase the input. 

Please share the formula so we can take a look properly. 

i am adding 1% tocopherol t-50 vitamin e
