    @DAS - thanks for the feedback!  I believe you can edit comments for only about an hour after you post it.  You might check to see if you can edit an old comment and let me know. 

    It’s set this way to prevent someone from deleting comments on long threads which makes the whole thread worthless.

    If anyone wants something deleted at a later date, they can just ask me.

    That sure looks a lot like a standard hair conditioner.

    @gld010 - yes, polymers can differ in molecular weight but still have the same name.

    Small companies can get away with it because the FDA does not have nearly enough resources to go after every cosmetic producer. And the penalty if they get caught is a letter which tells them to fix the mistake else risk getting fined. They can then just fix the mistake on the next product run which might take a while. Meanwhile, those mistaken labels stay out on the market.

    Thanks @Microformulation. The company needs to do a better job with SEO because if you type Aquaguard K12 in Google, nothing cosmetic related comes up. It’s a water treatment material.

    @cindyhr - if the pH of the water in your system is >5.0 then that preservative won’t have much effect.

    Cindy - Just because a formula doesn’t have water doesn’t mean it doesn’t need a preservative.

    Moisture can easily accumulate on the surface of your lipstick and if there is no preservative, microbes can grow at the interface.

    If product safety is a consideration, there is no good reason not to use a preservative in every type of formula.

    January 8, 2018 at 11:01 pm in reply to: With new ingredients or suppliers, what keeps formulators up at night?

    I’m not exactly sure what the question means, but I’ll take a swing at an answer.

    1.  Unreliable supply. If the supplier can’t meet order timing and specification, that’s a problem.

    2.  Single source. Related to the first. If I’m buying a custom blend and for some reason the supplier can’t deliver my entire product can be delayed or I can’t produce it. This is why I prefer never to be single sourced.

    Those are the main ones off the top of my head.

    That depends on what you mean by “significantly better”. From a performance standpoint, as @Microformulation said, Petrolatum is the gold standard. But it is also heavy and greasy. There may be other materials that work almost as well but don’t feel as bad. Certainly, there are formulas that do.

    January 8, 2018 at 2:16 pm in reply to: Average cost of manufactured bulk?

    The low cost shampoo brand that I worked on had formulas that cost 8 cents a pound for raw materials.

    300 gallons is probably the smallest “production”.  1000 or 2000 gallons is common.

    The answer depends on the company and types of price deals they can get on raw materials.  But a small manufacturer should be able to make the formula for $1 - $2 for 8 ounces.  Big companies can make it for a lot less.

    We’d need more information about your formula. Please list all the ingredients

    But yes, if you are using Glyceryl Stearate, you’ll need to heat the formula. And you’ll need something to suspend the mica / titanium dioxide. Otherwise it will separate out.

    I guess it depends on what you’re adding it for but as a humectant Sorbitol should work.

    @Jennova - I think from a legal standpoint they justify the claim as long as they don’t use preservatives listed in the EU regulations. I agree it’s a terrible claim which could ultimately be harmful to consumers.

    Since the science isn’t advanced enough to know what are the good microbes and bad microbes and how much you should have in the skin microbiome, I wouldn’t put much faith in their Good Skin Bacteria Technology.

    I agree with @Bill_Toge a company selling a product like this is being reckless.

    December 31, 2017 at 7:59 pm in reply to: What should be the ph value of rinse out hair conditioner, ideally?

    No, it wasn’t meant to be sarcastic. 

    No one is going to put those pH extremes on their head.

    When we do research on hair it is actually done on just hair.  Specifically, tresses which are made from human hair. If you want to see the pH effect on hair you could take a number of tresses, expose them to solutions with a range of pH, then examine the damage effects of pH.

    Of course, this would mostly be of academic interest but it would still be interesting know. These are the types of experiments we do in the lab to learn general principles about how the world works.

    Saponins are not good cleansers and there’s nothing hypoallergenic about natural ingredients that are known allergens to some people.

    But what do you expect from people who financially benefit by getting other people to believe BS?

    I’ve always found the terms for the different types of sunscreen troubling.

    “chemical sunscreen”
    “chemical free sunscreen”

    Yes. If I were knocking this formula off these would be the ingredients I’d start with.

    Alcohol, Water, PEG/PPG-20/23 Dimethicone, Acrylates/C10-30 Alkyl Acrylate Crosspolymer, Fragrance, Triethanolamine
