Hair oils

I need to formulate hair oil product that can be used as oil bath and hair serum at the same time, it contains:  jojoba oil , sesame oil, argan oil, almond oil, coconut oil, castor oil , cactus oil, BHT, vitamin E and Paraffinum liquidum.
My question is what are the suitable percentages for these oils to produce non greasy oil mixture? Consider that the highest percentage is the Jojoba Oil.
Thank you

Comments

  • I think the percentage can only be find out through experiments.  Adjust one at a time to find the optimum percentage. 

    Besides, in my opinion, the formulation is fine for hair serum. However, does it work as a oil bath as well?  This is because there is no emulsifier in the formulation to wash away the oil when come into contact with water. Correct me if I'm wrong...

    Newbie of formulation
  • PeiHoong thanks for your answer,
    Actually the formulation is registered as Hair oil bath but I want to use it as a serum as well.

    @dodipharma mineral oil is apolair oil vegeteble oils are slighty polair so in liquid form almost you will obtain two phases .
  • Terrible idea to be honest. Hair serum and bath oil are two very different products and should be made of different materials. 

    Hair serums are mostly made of silicones and oil is added at a tiny percentage for claims.

    Bath oil should include polar esters and an emulsifier, otherwise, instead of milky emulsion, you will have oil floating in your bathtub like in a soup.

    Or you can use literally any oil and market it as 2 in 1. This is going to be a bad product but there is no legal definition of what constitutes a hair serum or bath oil. The only requirement in this case is to mix oils with similar polarity because as Fekher mentioned above if you mix vegetable oil and mineral oil it will separate into two phases.

    Thank you for your feedback ?
    If we exclude the mineral oil , do you think its a better idea?
    and which of the above oils have similar polarity ? Please advise

    Thank you very much 
    if you have a better idea for the above formulation, I would be grateful.
  • All veg oils are more or less polar. So you can mix them all but don't add mineral oil, which is a hydrocarbon. Hydrocarbons are non-polar.

    The oil will still float on the top of water though.  With excluding mineral oil you will only solve the separation issue.

    @dodipharma the better idea wich i have is said by @ngarayeva001 in last comment  :)  .


  • IF this is for North America, there's quite a few lawsuits I've heard of when it comes to 'bath oils'... that thing gets everything slippery. I'd avoid it, especially for baths.
  • Of course oil will make everything slippery. That’s why it needs to be mixed with an emulsifier. It turns into milky emulsion when added to water. This way it can be rinsed off with warm water. You don’t even need to wash the bathtub after it. Otherwise you will have a greasy soup in a bathtub
  • Thank you everybody for your precious comments , I think we will exclude the idea of bath oil as it seems to be bad idea.
    but I have one more question please, can we use the combination between vegetable oils and Paraffin as Hair oil and if yes is it better to be used as a hair serum or hair mask? And what is the most suitable ratio between the veg.oils and paraffin?

    @dodipharma in liquid form just mineral oil and vegetables one are not mixcible cause mineral are not polair however vegetables are less or more polar so that difference of polarity make them not mixcible in liquid form .

    Why though? Why use two types of oils? Oil is oil. If you want something that works and is stable, use mineral oil/parafin. If you want pretty claims, use teh vegetable oil. They have the same end effect essentially.  
  • This product contains Liquid Paraffin.
    How they managed?
  • @amitvedakar based on the pictures I saw here and here, that product is likely almost entirely mineral oil. Not sure exactly how indian cosmetic regulations work but mineral oil is listed first in both pictures


  • @EVchem Yes you are right.  Liquid Parafin listed first.that is 93.2% & Vegetable oil 2.4%. Second is cyclopentasiloxane.
