Guys does D5 expires? If this nonsense passes I need to stock up ???? (for my personal needs I don’t sell products)
-
Thank you. I hope it won’t pass…

There are liquid pearlisers with glycol distearate https://www.ulprospector.com/en/eu/PersonalCare/Detail/1481/52073/TEGO-Pearl-N-300

@LincsChemist that’s extremely upsetting.. I know there’s was a ban of D4 and D5 In rinse-off products (due to toxicity to aquatic life) effective on 31 Jan 2020 in the EU, is there any new development?
-
Is it ASM or as supplied? Also too much peppermint

By the way, if it’s for non for profit and you care about cost you might want to go SLES/CAPB route. It would be easier to make and economical. It can be mild, just don’t make active surfactant mass too high and use a little more of CAPB. Plus you can thicken it with salt. With glucosides you would need additional ingredients to thicken the product. -
If it comes in a blend it’s probably at a low % and you should be able to use it.

Behenyl feels drier but many would not even notice any difference.
-
I would not rely on spf provided by oil. Perry has a blogpost here on this topic that explains it very well. Long story short, you might get spf 1-2, what does that change?
-
It’s all about marketing. Having said that it would make sense to have light sensitive ingredients such as retinol in a nigh cream and spf in a day product.
-
I am not even surprised. My friend who is all for natural goodness and persuaded that silicones are evil, absolutely loves kerastase hail serum. First two ingredients: cyclopentasiloxane, dimethiconol.

I used GMS+PEG100 Stearate (aka LotionPro 165) in low ph system. Worked as always.
-
I would say just use a different humectant. Inulin is tacky.
-
@AndrewSeel, what preservative are you using? Some preservatives plus salt cause cloudiness.
-
@AndrewSeel, in my case it was a problem with the plastic (the bottle) not the product itself. Try to transfer it to a glass bottle and see if the problem persists. If yes, it’s your formula, if no, it’s the packaging. Do you have any surfactants in your formula at all?
-
Aristoflex AVC and some very light ester.
-
@Blue_Lavander Go through L’Oreal’s patent for C E Ferulic. I believe you don’t have enough glycols to stabilise LAA.
@ketchito, there’s nothing wrong with 15% of LAA. Some researches suggest 20% is an optimal amount. -
Polysorbate 20 at 1:1 isn’t enough. It is added at 4:1 as a minimum and with certain oils it’s more.
-
Re preservative, I was going to say, up it to 1% but then noticed you have another 0.5% in oil phase. The thing is, preservatives must protect water, which is often hard to achieve because some of them tend to migrate to oil phase. So addicting it to oil isn’t very effective strategy.
-
Agree, not enough SLES
-
Apparently acids are electrolytes too, but those are weak electrolytes. Every time you see a supplier saying that this ‘incredible new polymer’ is electrolytes resistant they don’t mean salts, they mean acids.
-
Sodium is a key word here. Sodium is a metal. If there’s a metal in the beginning it’s a salt. Salts are electrolytes (but not all electrolytes are salts). Electrolytes break gel network of most polymeric emulsifiers derived from acrylic acid. Magnesium Ascorbyl Phosphate, Sodium Lactate, Zinc PCA, Magnesium Sulfate, Sodium Chloride.

Also aging process is very complex. Many people think it’s all about wrinkles, which is far from true. Skincare can only have some effect on the surface of the skin. But aging is about redistribution of fat, sagging of muscle and changes in bone structure. One can have an absolutely perfect skin with no wrinkles or sunspots, or textural issues and still look older than their age.

Unfortunately for us mortals, people who look like 20 at their 50 do so due to good genes, not cosmetics. As a ex-consumer, I would say Korean (and japanese) cosmetics is special because of the texture. Asian moisturisers are lighter and more pleasant upon application. On the flip side they you need more products to layer to achieve the same result that one heavy ‘European’ moisturizer can give. So, marketing aside, it’s all about aesthetics in my opinion.

@Amira, thank you for bringing up this topic. I first heard all these weird concepts (several months ago) on the haircare science subreddit that Perry mentioned above. Tried to look it up and couldn’t find any reasonable sources mentioning hair porosity. I also always thought there’s damage or no damage but now it’s getting complicated and people get quite religious about their hair.
