Parabens in Cosmetics

hi all

i am making bullet lipsticks since two years. going very well but one issue my Lipstick expire within one year.

i add vitamin e (pure tocopherol) so that oils in lipstick font go rancid. my clients are demanding more shelf life.

i want to add parabens to extend shelf life can you people guide which parabens should be added in lipstick formula plus what percentage is required. 

i started working on liquid matte lipstick as well and want to add parabens to extend shelf life.

parabens are ok to use for my purpose or is there any other option i could use to extend shelf life at least 2-3 years ? 

looking forward to hearing from you all.

    Parabens can offer a burning sensation in taste.  
    Are you sure you need a preservative?  Can you share your formula?

    yes i just want to increase shelf life of my Lipsticks that is one year and my client asking for longer shelf life

    my formula is based on some waxes and castor oil plus caprylic capric. woth some texture powders .. in end i add antioxidant as well so that oil dont go rancid soon.  my Lipsticks goes well for one year but after that they start giving rancid smell. i just want to increase shelf life. is there any other way to increase shelf life at least 2-3 years

    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

    Parabens will do nothing for oxidation.  Unless you;ve seen or cultured microbial contamination, a preservative is piob not necessary.    Look at labels of similar products.

    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

    The culture the product - find if a microorganism also contaminating.

    Is there a reason some people seem to be opposed to BHT as an antioxidant? I never see it recommended.

    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 
  • PaprikPaprik Member
    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 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.

    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.

    Are you having problems with syneresis? Looking at your oils, you're mixing polar and non-polar lipids?

    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

    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?
  • abieroseabierose Member
    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...
  • abieroseabierose Member
    And also culture test for microorganism contamination like @PhilGeis suggested
  • @Cafe33, I think it’s because BHT has bad reputation. Funny enough it’s used in food, as well as BHA. Hidden under one of those E codes. Good antioxidants, I use both. Especially useful in formulations with retinol.
  • PaprikPaprik Member
    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.

    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

    cap2 preser vative - think you're wasting your money.
  • PaprikPaprik Member
    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?

    actually that's just a list of oils that i usually use. it's not exactly all in one product :D
  • PhilGeis said:

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

    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

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

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

    Not to derail the discussion, but I'm wondering if you have any issues with syneresis? (Precipitation of oils due to non-compatible polarity.) I ask because isododecane is highly non-polar, whereas some of your other ingredients are polar (like sunflower seed oil.)

    I've recently started experimenting with Rice Bran Wax as it is said to prevent syneresis, and it's going well so far!

    I'm interested in trying microcrystalline wax as well, right now I'm using emulsifying waxes, Rice Bran Wax, Cetyl Alcohol and Stearic Acid. Are you happy with the microcrystalline wax?

    ETA. Sorry, I see someone already asked about syneresis LoL. Ignore.
