Unfortunately this supplier lists tocopherol as preservative. Please ignore small suppliers’s classifications.

[ngarayeva001]

There are several suppliers in the UK. Check naturallythinking. They sell some Euxyl products.

Start with this http://makingskincare.com/knowledge-base/

Read knowledgebase of chemistcorner, then read knowledgebase of ulprospector, then analise as many commercial baby products as you can find and don’t fall after ‘natural’ and ‘organic’.

And regarding rancidity 10% of Vitamin E? Tocopherol I assume.. it is pro-oxidant at this concentration.
Have you ever worked with grapeseed oil? It goes off in three months at a room temperature in a product. It’s iodine value is one of the highest of all vegetable oils.

[ngarayeva001]

Baby products are not made from ‘natural’ oils. They are made from mineral oil and thickened with microcrystalline wax. Why? They don’t cause allergies unlike all these lovely wonderful natural organic ingredients.

Agree with Pharma. You should make it and see whether you are happy with the result. But without getting into details, I would add small amount of stabiliser (xanthan or carbomer).

[ngarayeva001]

Thank you @Pharma!

A bit of topic, SA dissolves in PG at quite a high concentration if you heat it to 70C. I managed to dissolve 30%. The trick is to cool it down and then add to water very slowly (if making a toner). Is there a reason why SA shouldn’t be heated? 

[ngarayeva001]

@Diadem, lookup in the free formulas section on the chemistcorner website (not the forum). Most of people here create formulas as their main job and charge for it. 

You can post your formula that doesn’t perform as you want and ask for a piece of advice but you cannot ask someone to write it for you.

Having said that, I personally don’t like sulfates on my chemically treated (or should I say chemically abused) hair. I use SLES/CAPB shampoo once in two weeks because I love silicones and polyquads that tend to build up. 

Everyone can have their preferences. But the fact you don’t like the taste of broccoli doesn’t justify starting a fear mongering campaign and say broccoli cause cancer.

So much nonsense.. I couldn’t help it and commented on a couple of posts but then realized it’s useless. They say SLS is used in clinical studies as a skin irritant… yes, undiluted, covered and left for hours! If you drink too much water too fast you will die too. Doesn’t make water a poison.

Pharma said:

BTW, 15% ascorbic acid equivalents equal 35% ascorbyl palmitate or 96% tetrahexadecyl ascorbate. Just saying…

96%… I heard controversial opinions about tetrahexadecyl ascorbate. Some papers suggest it works but the sample is too small. I used 10% for a couple of months (made it myself, I don’t think you can buy it at a such concentration) and didn’t notice any difference.

[ngarayeva001]

Just a guess… Could there be a problem with polarity of my oil phase? I use dimethicone which is non-polar with polar esters. Could that be the reason?

[ngarayeva001]

Do you have any abrasive particles in this product? Is it a ‘physical’ scrub?

[ngarayeva001]

Ready dispersion (for makeup) in octyldodecanol. Emulsion without pigment gets viscous after application of high shear. So I guess it’s not easy to get viscous w/si with pigments. Anyone tried?

[ngarayeva001]

I played with these emulsifiers for a quite a bit before I added pigments. I tested these with several esters including octyldodecanol, no problem at all. It’s clearly about pigments. Oh I forgot to mention the emulsion is thickish with 10% of pigment blend (which translates to 5% pigment and 5% of octyldodecanol), but the coverage is too light.

[ngarayeva001]

It is a pain indeed. Unfortunately I only managed to find pigments in octyldodecanol. I didn’t apply HLB system (should it be applied for w/si?). It works fine when I add pigments to the oil phase. It emulsifies and stays together at a room temperature (I didn’t stability test it). But the texture isn’t even close to what I want. I will increase level of emulsifiers, I think it’s always a good idea.

[ngarayeva001]

I understand that pigments broke the emulsion. I wonder if that can be fixed by adding some emusifier to the pigment mix..

[ngarayeva001]

@fee, phenoxyethanol is not sufficient. It doesn’t protect from the mold. if you want to use phenoxyethanol use a blend with something else like ethylhexylglycerin https://www.ulprospector.com/en/eu/PersonalCare/Detail/2987/74345/euxyl-PE-9010

I personally prefer either Germaben II or Germall powder, for transparent products such as micellar water, but those are parabens and formaldehyde releasers and might not suit your marketing story.

[ngarayeva001]

@Dtdang, may I ask if you bought ethyl ascorbic acid from a retailer (DIY quantity)? I can’t find it anywhere. Sorry for off topic.

[ngarayeva001]

I mostly use it for oil gels and w/o lotions. @Fekher, that’s your call. You are hair pomades expert.

[ngarayeva001]

Somewhat. What is your question?

[ngarayeva001]

…60 I assume. It’s not the best emulsifier. Also, it’s not clear how much oil you use, as you didn’t post the entire formula. As Perry said, you probably don’t have enough emulsifier, but without seing formula it’s impossible to say.

[ngarayeva001]

Am I over simplifying it?

[ngarayeva001]

What is emulsifying wax?
