    What about Benzyl alcohol??

    It should be soluble as is if you follow the percentages allowed in cosmetics (1% as per EU regulation)

    Two questions: 1)have you tried it yourself 2) Is the liquid transparent or cloudy? I tried to incorporate 1% of tocopheryl acetate to a serum. It took 4:1 of PEG-40 HCO (which is much better solubilizer than poly 80) to achieve  clear liquid 

    I tried to use Tween 80 to solubilise tocopherol and ended up having to use a 1:20 ratio to get a nice clear emulsion.

    August 10, 2020 at 1:36 pm in reply to: SK-Influx - Heat Phase?

    I am not sure if this is helpful, as I am also just learning about SK-Influx V but in this DIY serum recipe by the acid queen (Ally Reed of Stratia skin care which has the famous ceramides containing Liquid Gold serum), she used in the water phase that’s heated up to 70C.

    LG is very gimmicky. The sk influx doesn’t provide the marketed 3:1:1 molar ratio, and the addition of cholesterol is just driving it further from it..

    Maybe not the most elegant, but petrolatum is non-comedogenic, and its the gold standard for TEWL reduction. Although with some work you can probably make it feel nice ^^

    If you’re making it for personal use (and not as a marketing gimmick) I’d just recommend you skip it altogether. The % of ceramides in it is not impressive, so I doubt it would facilitate any massive difference in your skin.

    How about Saccharide Isomerate? 

    It’s not really that amazing, the only data I saw was by DSM, which is the manufacturer. Also, it’s expensive.. I might use it for “omg 72h hydration your mother will be shocked” claims but glycerin is always there for you and it costs next to nothing

    a bit off topic. i personally don’t like Lush. Their LOIs r really strange (to me)  some times they r like DIYish products.
    and now they say paraben is Safe Synthetics.

    *edit: I just checked the ingredient lists and I saw that they do use some preservatives in many products (relieved). for whatever reason they don’t mention that they use water in the mask of whatever on the ingredients list while its there in the video??*
     
    Their “how it’s made” videos terrify me!! It looks more like a salad/dressing production plant than a true cosmetic manufacturing facility.

    how is that not going bad in 2 minutes? bentonite and honey? that looks like a disaster. my guess is there is very little water compared to the honey and glycerin so that helps it, but it’s still sketchy

    no comment ..

    I’m wondering how is this even legal..

    To me, looks pretty good, but again, I would change the preservative. I dont know if the panthenol would do anything, but thats a whole another topic. Also beware of the allantoin recrystalising

    @ngarayeva001 yes, I 100% agree. this is a v rough estimate and you really need a proper ph meter or at least strips to determine the actual ph in the product. I use it to calculate the buffer sometimes.

    Question for you - should I just swap the preservative for a stronger one (reccos welcome) that way, I won’t need the BHT? trying to keep the ingredient list on the small side so i’m happy to cut what I need to in order to have a shorter list.

    Preservatives won’t do much for the actual stability of the extract, so you would need an anti oxidant. And for green tea BHT is pretty much the gold standard (at least I think so)

    I find that davines has great quality and a superior selection so you can match it to your needs. Sulfate free.

    I don’t think the gluconolactone/SB would be enough. I would make the pH6, and add a 3-5% niacinamide. Also I would use 0,3% HEC but that depends on what grade you have, so experiment with the %s and see what you like. Also Disodium EDTA is pretty much a must since you have some extracts. The green tea is very hard to stabilise so something like BHT is definitely welcome.

    @esthetician922 I will attach the file to the post. I have basically the same template as @ngarayeva001 ^^. Also, regarding the consistency, I also suggest Siligel. Also you could try a bit of HMW HA (it would look nicer, crystal clear. The siligel can sometimes make it kinda murky tbh)

    May 19, 2020 at 11:41 am in reply to: Is my formulation including too much or would this be ok?

    Oh my god the amount of HA in this is really quite a lot, it might be quite sticky, and it could be really thick. besides that, there’s no point in using that much NAG, you’re probably just wasting your money. Reduce to 2%. I would use 1,5% K940, it provides the best protection out of all of the above. Also, too much stuff for a first time imo.

    @maria
    I live in Poland, so they’re local to me. They do have some of the best prices here. Also some nice rare ingredients. I also like beautyever.pl, e-naturalne.pl, zielonyklub.pl (cheap and has some otherwise rare ingredients, e.g. oat oil and collodial oatmeal) and mazidla.pl. Mazidla has really high quality extracts (I think), and they have Cromollient SCE (hard to get outside US).
