What is the worst formulating advice you've seen on the Internet?

PerryPerry Administrator, Professional Chemist
Since literally anyone can write anything about anything on the Internet, there has been a proliferation of dubious formulation experts giving dubious advice. 

What are some examples of the worst formulating advice you've seen online?

I'll start...

Using natural oils as SPF ingredients - This is downright dangerous as people may go out thinking their skin is protected while it actually isn't. No, Carrot oil will not help you achieve an SPF 38 to 40!

    Just a general example- people thinking Vitamin E Acetate is either:
    1. a preservative
    2. an antioxidant that will increase shelf-life
  • PerryPerry Administrator, Professional Chemist
    @EVchem - yeah, that advice about vitamin E is all over the place and just mistaken. 

  • Emulsify your product with a whisk.  :#

  • Heat and hold for 20-30 minutes no matter what. Do it regardless of the emulsifier or co-emulsifiers. Also, add temperature-sensitive ingredients in the hot phase, even for 10-20 minutes, including antioxidants.
    I saw all those "instructions" on one entire post.
    Runner up: to prevent an emulsion from separating, add more antioxidants.
    Emulsify your product with a whisk.  :#
    I've seen this one before, too. I think some people are copying instructions from making chocolates and applying them to formulating cosmetics. xD
  • PerryPerry Administrator, Professional Chemist
    @RedCoast - yes, I think a lot of stuff you see about making cosmetics online is adaptations of food making.

  • The question was ‘which preservative is suitable for baby products’. Response:
  • Emulsify your product with a whisk.  

    Well if your product is relying  on sepigel 305 as the only emulsifier you can even emulsify it with a fork 😂

    @ngarayeva001 - ah yes, the vitamin E preservative nonsense. ugh.

    I visibly cringe every time I see "to use coconut oil as an spf and sun block" 😖...I've also read you can use coconut oil to whiten your teeth! 😳 There was definitely a minute where people were touting coconut oil as a cure-all...
  • Could someone please clarify for me the part about Vitamin C Acetate not having anti-oxidant properties?

    Any time any of the following statements are mentioned is definitely bad formulating advice.
    "You don't need a preservative for this lotion/shampoo/<insert other water containing/contact product here>"
    "Preservatives are bad"
    "Use essential oils as preservatives"
    :#
  • There are way too many websites proclaiming that essential oils are natural and therefore harmless and that fragrance oils are synthetic and therefore harmful. 🧐

    All that is missing is.....Bake at 350 for 25 minutes! :)

    The whisk people...have more than likely never heard of Sepi 305. :) 

  • To be honest, i think using a whisk is still fine because we can be slightly short of budget or basic equipment at home. Using a milk frother is worse.  :#

    @jemolian I must remember to tell our manufacturer to add "a pinch" of EDTA next time :D :D :D

    @ozgirl supposedly a pinch is about 1/16 teaspoon, so it's about 0.35g. I'd assume for EDTA, it's workable up to a 1kg batch for a pinch?  :D

  • It’s fascinating that a person who measures ingredients in pinches and teaspoons is ok with EDTA, mineral oil and methylparaben.

    @ngarayeva001 Why? Back in the good old days of alchemy, their measures were even worse but they seemed to feel quite confident using things like mercury, lead oxide, deadly nightshade, and goose droppings in their salves and ointments. On the other hand, why should non-metric measures mean that someone is supporting the free from boom? Wouldn't the USA be all organic and fairtrade if it were so? :smiley:

    Also, any formula (especially with essential oils) that blatantly ignores the IFRA Maximum Skin Exposure Levels.

    "Hyaluronic acid is the best and strongest moisturizing ingredient" this ingredient costed me a lot of money and didn't do anything beneficial or noticable.
    I have eczema and in winter i strongly need to use a potent moisture or a corticosteroid drug for it. The only moisturizer that helped me was petrolatum based lotion with %20 Glycerin. It is not aesthetically pleasant but it workes and you can feel the moisturizing benefits from first use.
