There are more, I will send addresses as they come to the fore.

“Will the type of foam dispenser affect how the foam turns out greatly?”

Yes

o-cymen-5-ol is more commonly known as carvacrol - a common constituent of essential oils especially oregano.

Very strong smell so if you want to go around smelling like a pizza - fine. If you don’t, best give it a miss.

Remember, any hint of medicinal properties that you may make puts them in a new category of product.

[johnb]

Far too much emulsifier.

PVP K30 is available on eBay USA where is is called povidone (not povidone iodine) and UK (as PVP).

Some of the ingredients which are not classified here are synthetic may well be products of a chemical factory merely to keep up with demand and costings over the natural product. Glyceryl oleate, tocopherol and niacinamide come to mind.

I would forget about your “natural” requirement if those products are your standard.

Not an answer to your query, by any means but, a very large European soap manufacturer (multiple thousands of tonnes per week) I worked for many years ago used a mix of magnesium sulfate and sodium silicate as a soap preservative.

I enquired why they did this and received the answer “we’ve always done it like this”.

I did a bit of experimental work and found that yes, soap with the preservative mix DID keep better than soap without.

I left the company and never found out anything more about it.

[johnb]

Is the non-declared part merely water and preservatives?

A quick glance at the delared formula suggests too high a proportion of emulsifier.

[johnb]

Behentrimonium chloride (C22) has much better conditioning properties than cetrimonium chloride (C16).

[johnb]

PEHG = Iscaguard
PEHG is a blend of Phenoxyethanol with efficacy boosting
Ethylhexylglycerin. With its primary registered function being a skin
conditioning agent, ethylhexylglycerin improves the quality of cosmetic
products while reducing the reliance on preservatives. Use level:   0.5 – 1.0 %.

[johnb]

Seems a bit battered to have only a 5% price reduction from new.

[johnb]

What is your intended use?

[johnb]

A very close relative of this material is cetyl ethyl morpholinium ethosulfate (the difference is the chain distribution of the hydrophobe). It is/used to be called G263 (Atlas Powder Company).

Several years ago I had a call for help from a manufacturer whose air freshener sprays had a metallic “off” odour and failure of the pump mechanism after a fairly short period after first use.

Without going into unnecessary detail, it turned out that the liquid spray in contact with the metallic parts of the pump mechanism  was causing severe corrosion such that the spring in the actuator was destroyed after about six weeks in contact with the spray liquid and there was severe pitting on the surface of the ball bearing.

The product was stable during storage as the pumps were not primed after filling and there was little or no liquid/mechanism contact prior to first use.

Eye cosmetics are not my areas of expertise.

I replied to your thread for you to bear in mind the delicacy of the tissues in the eye area.

[johnb]

Irritating or not, I would use something known to be more gentle. Eyes are very precious.
If you want a viscosifier, a water soluble cellulose (hydroxypropylcellulose) would be more suitable in case of contact with the eye mucosa.

[johnb]

Suppose it depends on the origin of the beta glucan.

Beta glucan can be drived from cereals (esp. oats) and from micro-organisms (esp. yeast). There are huge differences in the commercial scale and yield of these materials which, no doubt, corresponds to the price hike.

Are you claiming any special attributes to the ingredient (e.g “made from yeast”? If not, and you are just using it as a thickener, then the cheapest product that does what you want it to do will be better.

If you are making any natural claims, well, it is far from being natural  - the beta glucan having undergone vigorous chemical modification.

[johnb]

What is the objection to alcohol (ethanol)?

[johnb]

As you have assurances that a presevrative is not required, you should approach your supplier with your concerns - with the evidence you have and see what their response is!

[johnb]

Note that the Akzo/MakingCosmetics product is a 25% solution whereas the PVP K30 is 100% active powder - you only need one quarter as much.

You may need more than a “dump-it-in-and-stir” method to dissolve the powder form but it should be fairly easy to do if you take it slowly and carefully.

[johnb]

Reverting to my previous post on this: “Does it work“.

Your first steps ought to be acquiring intellectual property rights.

If you don’t do this then there is the strong possibility that anyone “in the know” about your invention/idea can/will steal it from you.

[johnb]

I really wouldn’t bother.

As it states on the Biostyle blurb sheet:
“BIOSTYLE CGP polymer delivers performance equivalent to PVP K-30 and
PVP/VA in hair gel formulations.”

So, on their own recommendation, it is no better than PVP K-30 which you can get easily from eBay UK - OK it comes from Poland but, I have bought from that supplier and found them very reliable. Look under Polyvinylpyrrolidone.

[johnb]

I assume you are rquiring BIOSTYLE CGP polymer from Akzo Nobel.

The best thing to do is contact Akzo for information on where else you can get small quantities.

Lots of info on Google.

[johnb]

8%???????????????????

Considering most of that will be washed down the sink without even touching a hair, then yes, far too much.

[johnb]

I’ve looked at inulin in the past but didn’t find any special attributes that would sent the world of cosmetic science into a tizzy.

Looking at the claims on the patent, it seems that most (all) of the validity is greatly diminished by having Claim 1 full of provisos (“free from”, “apart from”) and such like.

The patent has a priority date of 2003. Nothing has appeared on the marketplace which utilises any attributes that this patent may offer so, I assume it’s not any good - although the patent legal processes are still being pursued.

[johnb]

I think that the Proteol APL could be reduced without much effect on the performance to, say, 2.5%

This is only a guesstimate.
