    I suspect the limonene comes in with the fragrance/flavor.


    I agree the problem isn’t the certified organic ingredients.  Those ingredients are perfectly fine. The problem is the people who market organic cosmetics put Marketing considerations over Product Safety.

    To be fair, I think the class action lawsuit is a bit much. Lots of people are allergic to different components of cosmetics.

    However, @bobzchemist is right, there is a problem with organic cosmetics.
    I hope we see more lawsuits like this to discourage people from launching products that are not properly tested or don’t have a suitable preservative system. I’m still surprised no one went after Badger Sunscreen company for selling contaminated products.

    I have not heard of this but it is not surprising.  It is very difficult to get many certified organic ingredients.

    Those terms are just defined terms.

    Qualitative testing - Using subjective measurements on some characteristic of a product.
    Quantitative testing - Using objective measurements to characterize a product.
    So a pH measurement or a viscosity measurement would be quantitative measurement because you end up with a number based on some defined scale.
    A measurement like appearance or odor would be qualitative because it relies on a subjective measurement to get a test value.

    ^ What @Bill_Toge.  If there is no water in your lipstick, the pH measurement is meaningless.

    I’m curious why you want to know what the FDA thinks a preservative is.  As far as cosmetics are concerned the FDA does not require people to use preservatives.  Their only requirement is that you cannot sell unsafe products.  And most products that don’t have preservatives are unsafe.

    Did you try to make the formula?  What did you get? 

    I don’t think you’ll be able to do it with Ceteareth 25 in your formula.

    You are trying to mix oils with water so having an emulsifier will make the formula more stable. Cetrimonium Chloride and Cetyl Alcohol will have some emulsifying ability but not much.  When you say the formula is “fine” I’m not sure what you mean by that. 

    Have you done a stability test to determine how long the formula remains “fine”?  Without a proper emulsifier, I suspect you will see formula separation over time.  Maybe not but I wouldn’t take that chance on a commercial product.

    You should probably have an emulsifier in the formula. A blend of PEG-8 Dioleate and Glyceryl Stearate should work for your chosen oils.

    Adding the EOs in the cool down phase is ok. You probably shouldn’t add them later though as the formula might not be stable (or it might be, you’d have to test it).
    For pH adjustment, I’d make a batch, test the pH then add enough citric acid to reduce the pH to where you want it.  Make note of the amount you used then when you make the next batch put that much citric acid in the formula in the water phase. You should end up with a pH pretty close to where you want it.

    You haven’t really provided enough information to answer your questions. Please list your formula (e.g. what is your emulsifier, what is ratio of water to oil, what essential oils are you using..etc.)

    Adjusting pH between 3 - 10?  That doesn’t make sense. 3 is acidic, 10 is basic. You couldn’t adjust something to pH 10 using citric acid unless the starting pH was something like 11 or 12.

    December 23, 2015 at 3:35 pm in reply to: Getting a job with a chemistry degree (and not cosmetic science deg.)

    I think your best bet would be to look at jobs at the raw material supplier companies of the cosmetic industry.  You can find those companies by looking at a list of industry suppliers like this.

    Also, be sure to get involved with the Ontario SCC. They hold a number of meetings during the year and the people that go to those meetings will be the ones who would be aware of available jobs.
    I don’t think you need to get a degree in cosmetic science at the moment. You could learn most of what you would need to know through a class like the SCC Beginning Cosmetic Chemistry course or even our online cosmetic science course.
    Good luck!

    I wasn’t suggesting that you couldn’t produce the shampoo under vacuum conditions. I was just saying it isn’t necessary. Most companies in the cosmetic industry do not and excessive foam is not a significant problem.

    @ashish - I worked at a big shampoo company and we never made shampoo under vacuum conditions.

    I doubt there is just one fragrance that does it. I agree with Bob - ask a fragrance house.

    December 21, 2015 at 6:48 pm in reply to: Levels of Fragrance

    Yes, as @Belassi says, it depends on the fragrance.

    To figure out the amount of fragrance to use you need to consider a number of factors including cost, compatibility and consumer perception. To me, the most important is consumer perception.
    You should pick the lowest level to use that still satisfies the consumer.  To figure out this level requires you to test it with consumers.
    I personally think that 2% fragrance in any formula (except fragrances) is probably too much. A number of ingredients in fragrances are allergenic to a significant number of people so it’s best to minimize the amount that you use.

    I think people avoid silicones in organic products because the only way you can make them is through synthetic processes.

    Silicones do not cause breakouts.

    Thanks for the input!

    My thinking on Functional vs Aesthetic Modifiers is in terms of how it affects the consumer.
    So functional ingredients are ones that provide a benefit to the product user.
    Aesthetic modifiers are ones that affect the formula but don’t really provide a benefit to the product user.
    For example, pH adjusters do provide a function to the formula but they don’t provide any functional benefit for the consumer. Aesthetic modifiers are the ingredients added to modify the functional ingredients. (e.g. make it the right pH, make it less sticky, etc.)
    I do agree that the aesthetic modifier category could be better broken down into things that affect different sensory aspects of the formula.  
    Thanks for the input. I’m going to rethink some of this and try again.

    You can heat the batch up to ~40C and use slow mixing to get rid of the bubbles. Of course you may have to add back some preservative depending on what you are using.
