  • Kind of Emulsifier to use

    Posted by Honeybean on March 28, 2016 at 8:11 pm

    Hi,

    I’d like to know what type of emulsifier I should use to mix with below ingredients. Please help me.

    #1:

    Purified water 100ml
    Rose hip seed oil 1 drop
    Vitamin E oil 1 drop
    Almond oil 1 drop
    Avocado oil 1 drop
    Rosemary essential oil 1 drop
    Other fruits powders 150-200ml (still trying to figure out the amount)
    #2:

    Purified water 100ml
    Rose hip seed oil 1 drop
    Vitamin E oil 1 drop
    Almond oil 1 drop

    Avocado oil 1 drop
    Tea tree essential oil 1 drop

    Other ingredients powder based 150-200ml (still trying to figure out the amount)

    #3:

    Purified water 100ml
    Rose hip seed oil 1 drop
    Vitamin E oil 1 drop
    Almond oil 1 drop

    Avocado oil 1 drop
    Lavender essential oil 1 drop
    Other ingredients powder based 150-200ml (still trying to figure out the amount)

    I might replace almond oil or avocado oil with jojova oil but the amount is the same. Only 1 drops each.

    Thank you so much!

    What are you trying to make? From the ingredients listed, you will have, at best, a paste.

    I am not sure what you are trying to make either but it is important to convert your measurements to weight rather than drops. This will help replicate your products in the future.

    Like others, I wouldn’t weigh-in without better measurements. Wt/wt%, not drops is the proper documentation standard.

    Thank you so much for the comment. I’m trying to make several kinds of face mask. I will measure the weight and re-post the question.Do you guys have any suggestion for a scale to measure the weight that I can purchase? I only have measurement spoons right now.
    I’m totally new to formulating cosmetics, so bear with me if I post stupid questions…Thanks.

    You can pick scales on ebay quite cheaply. Look for scales that are designed for jewellery as these will often have more decimal places.

    Also don’t forget your preservative.

    Check out swiftcraftmonkey’s blog for some great information about making your own cosmetics.

    Hi Honeybean!

    I’ve worked with carrier oils and essential oils a lot over the past 10+ years, and I’ve worked with making many types of facial masks, too. Here are my thoughts:
    • Consider selling this as a dry mix — without water. The small amounts of oils you are using can easily be mixed into the powdered ingredients. 
    • In fact, the amount of oils you are using is so minuscule, it is likely not providing much effect in your product. 
    • By creating this as a dry mix, you will save on shipping costs, as water is a relatively heavy thing to ship. (Just provide instructions to the consumer on how much water to add per each use.)
    • By creating this as a dry mix, you will not need an emulsifier if the consumer is to mix this up as a fresh batch immediately before each use. 
    • By creating this as a dry mix, you will not need a preservative.
    • I also think that any fruit or vegetable powders and extracts may get quite gooey/slimey, off-colored, and possibly strange-smelling if sold as a wet pre-mix — even if you used a strong preservative.
    • I strongly agree with everyone else that you should formulate based on precise weight rather than on drops — assuming you are ultimately intending on making large quantities. A decent jewelry scale should cost between $25 - $40.
    • As ozgirl states, check out swiftcraftymonkey. Susan (aka “Swift”) is AWESOME! She is a chemist, and always provides fact-based, easy to understand explanations and instruction.
    Best of luck!
