    @Gunther - Ceteareths are blends of cetyl & stearyl alcohols. Since they are solid until about 60C they don’t make good solubilizers. Oleths (since they have a double bond in the hydrocarbon chain) melt near room temperature which makes them more appropriate as a solubilizer.

    @amalgbr - You make the formula in a lab and see whether it meets your standards.

    The FDA does warn customers not to use these products because of safety issues.

    https://www.fda.gov/Cosmetics/ProductsIngredients/Products/ucm137241.htm

    The companies are taking a significant legal risk.

    Yes, it’s most likely a change in fragrance causing the problem. You’ll need to work with the fragrance house to help fix the problem.

    @Lisani - it doesn’t have to be but you can mix it with that if you like.

    Decide on the batch size.  Say 100g or 100kg

    Then weigh out all of the ingredients.  (e.g. 13g or 13kg of Cetearyl Alcohol)

    If you want a different batch size, say 200 kg, then you would take a percentage of that.  200 * 13% = 26 g or 26kg of Cetearyl Alcohol

    Betaine is a foam booster but by itself it isn’t a great foamer. But you’ll just have to try and see if it gives you the foam level you want. That % active level is a reasonable start.

    I agree with everyone else about the honey percentage and the lack of preservative being a significant problem.  No, honey in this system will not be self-preserving.

    It depends on your fragrance. I’ve had success with Polysorbates and Oleth-20 / Oleth-40

    If you’re making cosmetic products, a magnetic stirrer isn’t really necessary.

    Yes, companies have made gel with HEC. On most measures, nothing works better than Carbomer. That is why it is the most popular ingredient used for making hair gels.

    You could add a little Violet #2 to offset the yellow color.  But ultimately, the quality of the starting raw material will have the most impact on the yellowish color.

    @mikethair - “inferior” is merely my opinion and refers to the complaint in the initial comment that “foam is not that rich.” 

    If you did a laboratory evaluation of the foam density of the best made soaps versus the best made modern surfactants, the new technology would win.

    Since your customers like your product, then your foam quality is sufficient to match their expectations. They obviously don’t share my opinion that the performance is inferior.

    @mikethair - I can understand your defensiveness but I think you may have misunderstood some of the comments here or at least mine. The fact that you sell soap doesn’t automatically negate your opinion as I suggest above about the Vermont soap company. 

    I don’t think there is anything wrong with soap. There is clearly a market for it. People like it, it’s been around for centuries and it works for cleaning skin. 

    My objections are all about their unfounded claims & lack of support. They also have a heavy dose of unfairly bashing their competitors which I find objectionable.

    @Sibech - Interestingly, the “gives you wings” probably isn’t a great example. Red bull was recently sued and found guilty of making that exact claim without proof. https://www.nbcnews.com/business/consumer/red-bull-drinkers-can-claim-10-over-gives-you-wings-n221901

    But the “greatest product in the world” is considered puffery by the FTC.  https://www.consumer.ftc.gov/sites/default/files/games/off-site/youarehere/pages/pdf/FTC-Ad-Marketing_Looks-Good.pdf  “Greatest” means something different to everyone so it’s considered puffery. If you said something like “best selling” then that’s a quantifiable claim which would require proof.

    @MarkBroussard - yes, calling it a hoax is too strong. I would say that the importance of it as a distinguishing marketing characteristic is overblown. Practically all standard cleansers would be “pH balanced.”

    Here are my comments.

    I agree that “pH balanced” is mostly a marketing hoax. 

    1.  This is written by a company that is selling soap so right away I’m going to discount the veracity of their claims. They have a stake in making you believe something beneficial about their products. That’s not to say it’s wrong, it’s just that I don’t automatically believe it just because they say it’s true.

    2.  I know they were trying to be funny with the line about 99.72% of claims are fabrications. But the reality is that it is illegal to make false claims. Large companies will have support for all the claims they make. Or the claims are classified as “puffery” which are not expected to be believed and so don’t require proof.  (e.g. this is the greatest product in the world)

    3.  “most effective way to clean it off,,,is using an alkaline foaming system (soap!)” - There is no proof for this and it is quite likely wrong. 

    4.  “the mildest cleanser you can use – properly made handmade style bar soaps” - This is just false. There are plenty of synthetic surfactants that are more mild than a soap.

    5.  “We have testimonials of dry skin conditions disappearing” - Testimonials aren’t evidence of product performance. Writers could be hired or consumers that like the brand. It has nothing to do with how well the product actually works.

    6.  Artificial color has zero impact on product harshness 

    7.  The claim that natural oils saponify is dubious and unproven.

    8.  “12% of us are sensitive to detergents” - this is just a made-up stat.

    9.  “Studies have shown…” - evidence asserted without proof can be dismissed out-of-hand. What studies show this?

    This whole explanation seem biased, disingenuous and manipulative. It’s soap marketing with a healthy dash of competitor bashing and fear mongering.

    You just need to include a holding polymer like PVP.

    Yes, you get a certificate of completion if you go through all the modules and score high enough on the quizzes. It’s the kind of certificate you would get for completing continuing education courses through the Society of Cosmetic Chemists. 

    But it’s not like a diploma you would get from the University of Cincinnati or another college. 

    I know there are a number of online courses that claim you get a “diploma” but I think that is misleading to students. Certificates and diplomas are only worth something if the people you are showing it to find that compelling. Our course is primarily focused on teaching you information. The certificate is a bonus.
