Examples of silicone-free brands:

Yes, I do really believe in that. In fact, you can formulate a product with polymers and you won’t need silicones because polymeric emulsifiers don’t soap like conventional surfactants do. Or you can formulate a silicone-free product with rather unpleasant texture but market it as natural/green/clean/organic/vegan and people will still buy it.
I have 6 varieties of dimethicone in stock. I am not a “clean” formulator. -
Binds with keratin in hair? That explain why it’s impossible to get rid of it. It stains pillowcases, it stains everything. Even worse, it is impossible to apply any other dye except for black after it.
-
Well there are many “silicone free” brands even now
-
I agree with Doreen, however my question is what is your formula? Alcohol is self preserving at a certain concentration.
-
@Doreen, good topic! I think I was lucky because I dispersed carbomer in veg oil many times. Will be more careful now.
-
Henna isn’t that temporary. It’s actually more permanent than some dyes and I learned it the hard way.
-
There’s not much difference between the stick blender above and dynamix. The bosh might incorporate more air but I don’t think it is worth difference in price.
-
Thank @Sibech, this’s very useful information. I thought the restrictions are because of Diazolinidyl Urea.
-
Also is there any serious research indicating that formaldehyde donors are not safe? I ordered germall powder recently and the supplier specifies that it’s banned in the EU (they probably didn’t go into details and just said it’s banned).
-
There’s one utterly surprising thing. I understand your point @Window that market at large won’t accept it. However, look at LOI of any luxury product. Any of those outrageously overpriced products: chanel, dior, la prairie, guerlain, shiseido, la mer, SK-II. I analyzed hundreds of those and all I see: silicones, mineral oil, esters, petrolatum and parabens. Yet there are enough people who are ready to pay hundreds of dollars for 50ml jars of these moisturizers.

Organic, vegan… not good enough! It also should be palm free, ‘natural’ and handmade ?
Belinda Carli of the instutute of personal care science posted a video recently on how to formulate organic, vegan and palmfree product. That’s a challenge! -
@Belassi, I understand that it is impossible to summarize in two sentences but can you set me in the right direction (what to read/lookup). How do you formulate a product that is stable without standard stabilisers? I remember you mentioned that you don’t use polymers either.
-
I haven’t tried the one you are referring to but there’s one stabiliser with xantham gum that I like. It’s called siligel and it’s has much nicer texture than xantham. Products with carbomer are typically more ‘fluffy’ and airy.
-
If you pair it with propanediol it will be less sticky.
-
PEG-8 Dimethicone adds some nice shine. But as Fekher said it reduces transparency (but not much).
-
IPM can replace caprylic/capric but vegetable oil will not replace ester in terms of feel. Oils are too heavy. The closest you can get is fractionated coconut oil.
-
Does it mean that mathematicians are weak in chemistry…. provided that I mixed anionics with cationics ones it might be true ?
-
An alternative to a stick blender is an overhead stirrer provided that you don’t need high shear. So if you use polymers and stick blender instroduces too much air, you can find a cheap chinese overhead stirrer on ebay for $100. And they work fine. You can get much smoother texture of your lotions with an overhead stirrer. Also you can set it up for, say, 30 minutes and leave it do the job. You can’t do that with a stick blender as you have to hold it.

@Dtdang, I am in a very different camp. If many are sceptical of “not natural” whatever they mean by that, I am sceptical of anything with label “natural” on it. I love esters and genuinely think nothing can beat petrolatum. There are only a couple of “natural” materials that I like: above mentioned Montanov L, Montanov 202 and Siligel (amazing gel maker and stabiliser).
So, if you are not formulating for clients who demand “natural”, organic, palm oil free, gmo-free, vegan etc. just enjoy conventional materials. They are much better.

@Fekher, I had a lot of back and forth with HLB system. I used to calculate it before but many experts say it’s just a starting point, and if you have good emulsifiers blend such as glyceryl stearate/PEG100 stearate you don’t really need to calculate HLB.
I don’t really see much difference when I do calculate and don’t calculate HLB (but I don’t do proper stability testing, what I mean by no difference is that I see no separation for 5-6 month in room temperature). Also HLB ignores thickeners that do not have emulsificaton properties but act as co-emulsifiers (cetearyl alcohol, cetyl alcohol etc). -
Yes, they both can handle quite high oil phase. But I don’t think they are considered natural under any of the standards.
-
If you are sure that you need a homogenizer you can lookup used silversons on ebay. But even if you are lucky those are not very cheap.
-
@MaisR agree 100% I started from reverse engineering existing products and that helped me to learn what ingredients do and how to work with them.

A mixture of Aristoflex AVC and Sepimax Zen. It will be very light and very peaky. Not “natural”.
