    What do you want the serum to do for skin?

    In truth, “actives” are typically just claims ingredients put in formulas to give the marketing people something to talk about. They don’t actually have much impact on performance so you can literally put in any ingredient that is compatible & makes a good story.

    July 7, 2023 at 10:06 am in reply to: Stats…. What percentage of the overall cosmetic industry….is homecrafters?

    Yeah, sales wise maybe $10 million worldwide? But it also depends on the company and what you consider “home crafter.” Someone could start in their kitchen, get some sales on Etsy, then ramp up production by hiring a contract manufacturer. This could then turn into a real brand like Drunk Elephant or Sunday Riley. I don’t think those would count as “home crafters” any more.

    While I agree with @anokea that Dimes make dollars, when your company gets big enough, those dimes cost you more than they are worth. Which would you rather have,

    10 customers who spend $10 million a year or
    1 million customers who spend $100 a year?

    Almost any company would rather have the 10 customers.

    As an aside, when I was working as a “cost savings chemist” we didn’t even bother working on a project if it was only going to save $100,000 a year. To a home crafter that’s a lot of money. To a corporation it’s not even worth spending any time on it.

    It depends on what’s in your formula, but increasing oil content can modify micelles which can change viscosity.

    If you want a helpful response, you should list all the ingredients in your formula.

    Unscented often means you added an ingredient to mask the odor of the formula. It could also mean you added a fragrance but the product has no specific odor.

    Fragrance free means you didn’t add a fragrance

    I think we had a corneometer with a built in pH reading. I dong think it was particularly accurate however.

    You could try adding some emollients (cetyl palmitate or capryl glycerides)

    Silicones, of course, will solve the problem.

    When you let the marketing story restrict your formulating, you usually just have to accept inferior performance.

    Can anyone with a higher brain power than me make any sense of this? Is there logic behind this? Are we expected to see such new surfactants as technology/understanding gets better/advances?

    Raw material companies recognize that natural/green/sustainability is a trend in the cosmetic industry. Thus, when launching new surfactants they look for things that apply to that trend. They don’t necessarily look at performance but rather sourcing. Yes, you can expect to see more surfactants like this.

    No, these surfactants are unlikely to perform better. But performance isn’t the key driver in todays green-focused market.

    June 29, 2023 at 4:52 pm in reply to: Why Did Moisturizing Shampoo Separate

    1. Because you loaded the formula with oil. Cleansing products are meant to remove oil. They should not be put into shampoos. You should have 0% coconut oil.

    2. Yes. Your preservative system needs a boost.

    3. Get rid of the oils. Get rid of the Glycerin. Reduce panthenol to 0.1%.

    No. Foam and viscosity are not directly related.

    If you list your ingredients maybe someone can give some suggestion on improving foam.

    Yes.

    No there shouldn’t be any side effects.

    June 27, 2023 at 5:38 am in reply to: Dimethicone vs PEG-12 Dimethicone in shampoo

    Yes I used it.

    PEG-12 Dimethicone is water soluble, so it mostly gets rinsed down the drain when used in a shampoo. No extra amount is going to get you the feel of Dimethicone

    Do you have a link to the new regulation?

    I don’t expect retinol to have a big impact on performance so the only impact I think it will have is that retinol containing products will be less irritating to more people.

    Ah, I was able to reply by clicking all the way on the right side of the Reply button. If you click in the middle it doesn’t work, but on the right edge, it works. Weird. Hopefully we get this fixed soon!

    I think the INCIs are fine. You didn’t name the brand & it helped shape the discussion

    Not all oils are the same and they can affect the micelle structure differently even if the ratio is the same.

    June 29, 2023 at 1:03 pm in reply to: foaming shampoo

    You have a lot of stuff in there that kills foam.

    Xanthan gum

    propanediol

    butylene Glycol

    glycerin

    mango butter

    fragrance

    extracts

    Use less of these (or take the out)

    Also, as Abdullah says, using a good foaming surfactant would help too.

    In formulating, if you put ingredient restrictions on yourself you are also putting performance restrictions on yourself.

    You can’t expect a Toyota to go as fast as a Ferrari. Similarly, you can’t expect inferior surfactants to foam as well as the good ones.

    Thanks - I’ll check it out. I really find this new system a bit annoying.

    As for your old account, it still exists. I think it just wasn’t imported in properly. I’ll send you login information so you can check it out.

    Well, it does something in terms of skin irritation. So, it makes sense to regulate it.
    I meant it doesn’t do much in terms of consumer benefit.

    I just went with what my IT guy recommended. I liked the past forum software (Vanilla) better but I’m a chemist not a IT guy so didn’t even know about xenforo.

    June 23, 2023 at 6:46 am in reply to: Preservative mfg's and product liability…….

    As long as the manufacturer can substantiate their claims and demonstrate under some conditions the product they are selling works as a preservative, I doubt they would have any liability if a finished product had microbial contamination. Having said that, in the US anyone can pretty much sue anyone for any reason. I just don’t think the finished goods maker would win.

    This would be similar to if a consumer used a product that was claimed to strengthen hair, but their hair still broke so they sued the product maker. Sure they could sue, but they would lose.
