I have been seeing a lot of hydrosols lately, kind of a solution in some water based formulas. And yes, there is also a green, eco, natural tendency brought by some fragrance manufacturers. I have been receiving feeds about it since last year.

Still the most dangerous thing about EOs are bees. I’ve heard scary and funny stories about labs overrun and people hiding in the bathroom because of it.

[DAS]

The three reasons I don’t formulate with EOs:
1) Price
2) Price
3) Stability

And yes, some could be irritant. And that’s why perfumists take home big fat checks, for formulating a sub that will be affordable, much more stable and with less allergens.

[DAS]

Active matter. You could use another cosurfactant in that formula.

[DAS]

You are quite low on AM, work on a 9-15% range and you will see an improvement in every aspect.

[DAS]

The Smart line of lubrizol works at higher pH range, so it’s ideal for this kind of formulation.

Yerba mate with sugar or honey, green tea is too bitter and dry for me, and cascara I don’t know what that is. Still, you won’t get much energy from those infusions. If you aim to have a healthy lifestyle looking for uppers ain’t a smart move, you are just changing one stimulant for another. Want healthy?. Eat healthy, do exercise and let your body rest through his natural cycle and at his own time. 

[DAS]

You don’t. Leave that to large companies that actually know what they are doing and buy the stable, tested and reliable raw material.

[DAS]

Since we don’t know what causes the allergies it will be irresponsible to make suggestions. Best you can do is go to a doctor and run the proper tests.

[DAS]

Enzymes can act as catalysts and hydrolyse esthers. It’s the first thing i’d knock out. 

[DAS]

No, it’s not. It is an ethoxylated fatty alcohol. No polyethylene glycol on it. A little sticky if you use too much, but great material.

[DAS]

Perhaps because pquats are more cost-effective. For a large batch this would be troubling and expensive.

[DAS]

It is a well known brand, but I still think brookfield is your best choice. For example, if you read any COA from a raw manufacturer most likely the viscosity test is made with a brookfield. 

[DAS]

I agree, people are buying a very expensive pee. I guess the reason no authority has stepped in is because most of it is harmless. I guess a little vitamin C or fish oil won’t do any harm. Now reading about the vitamin A example I would expect a reaction.

IMO a double blind is useless, to many variables and you would need too many people to get significant data.

Anyway, I rather eat my veggies…

[DAS]

Sadly there are many brands using it. It’s cheap and efficient. But I guess it will be replaced soon, it affects far too many consumers. This week I had to make 3 batches of shampoo because of it. 3 employees had the same issue, either them or a relative, scalp scaling similar to malassezia, and ZPT and ketoconazole was useless. The first ingredient I knocked out was MIT/CMIT. The result was almost instant, the next day scaling was gone.
I asked what brands they were using, went to the market and they all had MIT/CMIT. If 15ppm does that I don’t want to imagine what a higher concentration would do. And considering dog skin is way different and half the weight of a human in the largest breeds, a more severe reaction wouldn’t be strange.

[DAS]

I’m afraid the words cheap and rheometer can’t be used in the same sentence.

An used brookfield on ebay will be your best option. i wouldn’t waste money on those cheap chinese. Brookfield is the standard.

[DAS]

Yes, a concentrated/saturated formula could do that. Since you don’t even say what kind of product is hard to say, but don’t expect a good performance with 1:25 dilution using shampoo ingredients.

[DAS]

I don’t think it will make much difference if you add ceteareth, it is also nonionic. You could try a diferent ewax like this one.

[DAS]

You are changing anionic for nonionic, of course you will get a different result. Most likely you have to rethink your entire formula, you are changing the charge, it’s not a small change.

Why would you like to replace it?. If it ain’t broke…

[DAS]

Yes, those are different materials. For example EDTA salts are stable as a solution in alkaline pH. Huge difference, it can ruin a perfect stable formula.

[DAS]

Not at all. All you can use are INCI names. 

Here is the legislation and here a guide.

[DAS]

They work, and they also kill the foam. I wouldn’t put much faith on it for shampoos.

[DAS]

No problem, but if you want a real answer you should give us more information. A detail of what materials did you use and the order of adition are the basic. You should be as detailed as possible.

[DAS]

We can only guess, so i’ll say high shear during cooldown and/or order of adition.

[DAS]

@Gunther it’s a 10% solution.

Perhaps you will get better results with 1% CMEA. But still skin peeling shouldn’t happen. Try this.

[DAS]

BTMS has a better performance, to me it’s a waste of money.
