    Which ingredients would you say allow them to formulate without preservatives? 
    Here is a full ingredient list:
    Sodium Laurylglucosides Hydroxypropylsulfonate (plant-based cleanser), Lauramidopropyl Betaine (plant-based cleanser), Rosa Damascena Flower Water, Hydrolyzed Adansonia Digitata (Baobab) Seed Protein (Softener), Squalane (olive oil-derived conditioner).

    It looks like they are simply not preserving the product:

    Aqua (water), Sodium Laurylglucosides Hydroxypropylsulfonate (plant-based cleanser), Lauramidopropyl Betaine (plant-based cleanser), Rosa Damascena Flower Water, Sodium Chloride, Squalane (olive oil-derived conditioner), Hydrolyzed Adansonia Digitata (Baobab) Seed Extract (softener).

    This unpreserved product is best when used within 6 months after opening. Refrigeration not necessary

    And if it grows bacteria, they’ll just claim that it’s “good bacteria”

    LOL, Perry!

    I guess that after 6 months, just call it Mother Dirty Shampoo?

    It’s a risky strategy, perhaps the base Rose Flower Water is sufficiently preserved to make it last a while, so they don’t add additional preservatives.  Or, it simply is not preserved at all.

    Hah! I noticed that brand recently. Was even thinking to post one of their LOIs here. I think what is happening, they add preservatives and just say that they don’t. Who is going to catch them? Many of these natural brands use emulsifiers and then claim they don’t have anything but pure organic coconut, “healing and soothing” lavender and tears of virgins in their product. Which makes me think they overcame laws of physics and used some form of magic to persuade water and oil stay together.

    Jokes aside, I have been binge watching a youtube channel called Nile Red (a chemist running interesting experiments on camera) for a while and noticed an interesting video. So, this guy wanted to see if he can reverse saponification process. He wanted to take a soap, restore fatty acids through chemical reactions and somehow attach back the glycerol to restore triglyceride structure. The final goal was to make french fries with this oil :)
    To make his life easier he took a mono oil soap. The LOI claimed it’s just olive oil, no dyes, no preservatives, no fragrances. Having some understanding of soap making, I could tell right away that this “pure” soap had s#%t load of green colorant in it. Not being in the personal care formulation world and not knowing how this “pure” brands fake LOIs, the chemist assumed they say the truth and thought maybe it’s green because the oil was not well refined. He failed his experiment and maybe that was the very reason.

    The company doesn’t follow proper labeling rules, so you have no idea what is in the product. It could simply be that they are not reporting the preservatives that the raw material suppliers put in detergents like Sodium Laurylglucosides Hydroxypropylsulfonate & Lauramidopropyl Betaine.

    Imagine going backwards in cosmetic science advancement and calling it something new… I just feel bad for the consumer - they just want healthy skin 😥

    There’s so much misinformation now and although they are a minority but most vocal customers don’t just want healthy skin they want to make a social statement and feel more moral and virtuous  than the general crowd. So all this obsession with natural/gluten/paraben/silicone /sulfatefree/vegan/ethically source 
    free of toxic chemicals nonsense.

    Haha @ngarayeva001 :)) Tears of virgins couldn’t be ethically sourced, though.

    The website also mentions that they source herbal extracts without preservatives and then pack products aseptically. But how can a rose extract be aseptic unless you distill/boil it? Or is it how it’s extracted in the first place?

    They may be using some form of pasteurization of the aqueous phases as part of the production process.  That combined with NaCl may be sufficient to get the shelf life of their product as advertised.

    Note that they aren’t claiming that their products are not irradiated ( I jest )!

    The Rose water makes me think phenethyl alcohol, maybe they mislabeled it intentionally? Once I know I can’t trust the LOI my willingness to buy the product drops so fast

    Probably it’s just so little water that it’s self preserving due to low enough water activity?
