Hydroxyethylcelulose is an excellent thickener. It is used in KY sex lube.
Here is an ingredient list for their KY Liquid 5oz offering:
Water, Glycerin, Sorbitol, Propylene Glycol, Hydroxyethylcellulose, Benzoic Acid, Methylparaben, Sodium Hydroxide
They use Benzoic Acid and Methylparaben as the preservatives.

I was under the impression that Azulene was used to reduce redness. They make an azulene oil for reducing redness from shaving, branded Parissa Azulene Oil. It is a rich blue colour.
I tried to source Azulene on its own, but it is not commonly available to the home crafter. Plus, it is very, very expensive.
I would like to see how it would work when incorporated into sensitive skin formulas designed to work on ailments such as eczema redness, rosacea redness etc. Probably would be too harsh for rosacea, but might be okay for eczema.

Happy birthday. I love Karaoke. Nothing better than singing Foreigner songs in a Karaoke bar.

Phenoxyethanolused at approx. 0.5%-1%. Add at cool-down or at least below 100 degrees Celsius. Add to separate water phase (third phase) and then add to overall formula.

Concealers on that private part? I learned something new today!

I have experiented with DL Panthenol, which is the product you are most likely working with, not D Panthenol. D Panthenol is twice as active as DL Panthenol, more expensive, and harder to acquire for kitchen formulators such as you and I.
Anyways, the more DL Panthenol you use, the more of a ‘sticky’ after-feel your formula will exhibit. I have tried 20%, 15%, 10%, 8%, 5%, 3%, 2%, 1% and 0.5% DL Panthenol in a water based formula in the past. As Matt suggested, and in my experience, all concentrations over 1% felt ‘sticky’ to me, or not fully absorbed. Remember, the water in your formula will evaporate after being applied to the skin (over time) and the remaining ingredients on the skin will feel somewhat like they did before being added to the emulsification. Think of colloidal oatmeal in water as an example and how it leaves a ‘powdery’ feel on the skin after the water has evaporated or Aveeno and how it can feel slightly powdery after application.
I have read that Propanediol, when added to another humectant (in this case, DL Panthenol), increases the moisturization of the skin as compared to using one humectant only and excluding the Propanediol. You might want to dissolve the DL Panthenol in Propanediol first and add the combination to your formula.

If you are composing a sunscreen inspired TEWL lotion that uses Dimethicone, I suggest you use some PEG Dimethicone based emulsifiers to enable your water based ingredients to mix with your silicones, and in the process, add to the SPF factor of the final product. Surfactants such as PEG-10 Dimethicone, PEG - 12 Dimethicone, PEG/PPG-18 Dimethicone etc.
Regarding Dimethicone, it, by itself, provides a respectable SPF factor. Read this link (pdf) on silicones and SPF, from Dow:

Many scar gels use silicones for healing and for sunscreen protection while the scar heals.

Yes. What milliachemist said.

Nasal washes usually contain some basic components:
Purified Water - 97% or greater
Sodium Chloride - 0.9% - 1.5%
Humectant - 1%
Preservative - up to 0.5%Some ENT doctors suggest the use of 1% Johnson’s No Tears baby shampoo to be added to a regular, 0.9% saline wash routine so as to help chronic sinisutis suffers with clearing out infected mucous from their nose. The baby shampoo, which contains cocomidopropyl betaine, cleans the inside of the nose and washes away infectious micro-organisms in the same way hand washing cleans the hands. In other formulas, xylitol is used as the anti-microbial.
Do you want your nasal wash to decrease inflammation or kill microbes inside the nose or just rinse out the nose and moisturize it?

Fantastic! I also like the comment regarding water loss and adding back water that evaporated.

Many things will give you cancer. If you avoid all present and known cancer causing substances to date, you will eventually live long enough to get cancer from something else that is yet to be known as a cancer causing agent.
Regarding talc, as long as you dont apply talc to your genitals, you shouldnt get any form of vaginal cancer. Plus, any talc distributed in the U.S. has been asbestos free for decades. And I think people should be more concerned about the number of different sex partners they have throughout their lives as it pertains to increased cancer risks as opposed to fretting about talc powder in cosmetics.

Have you tried adding the HEC at the end of your formulation process? First mix the SA with the PG. Then add it to the water AND THEN try to incorporate the HEC last.

EWax is Cetearyl Alcohol and Polysorbate 60, right? It might be better to use a separate and distinct low hlb emulsifier to compliment the Polysorbate 60 in your EWax component and therefore reach the right HLB number for your oil phase. If something is separating, it means your emulsifiers arent working properly, in most instances. I thought Cetearyl Alcohol was more of a thickener as opposed to a straight emulsifier.
I have read that Cetearyl Alcohol can be used as a co-emulsifier when incorporated at rates greater than 5%, so you might want to get the two ingredients - Cetearyl Alcohol and Polysorbate - separately, and then add more Cetearyl Alcohol into your formula to get to that 5% threshold, while still continuing to use Polysorbate 60 as you desire.
MakingCosmetics distributes both of these ingredients. There website is:

Benzalkonium Chloride is used in many nasal washes. From and FDA perspective, yes it is safe to use.
But BC paralyzes nasal cilia and many nasal product users try to avoid it. -
While I think companies should be held accountable for injuries caused from their products’ usage by the general public, I dont think marketing claims in the personal care product industry should be so tightly restricted. Especially when natural products and homeopathic product marketers are able to get away with the claims they make. How can the average homeopathic marketer dilute a product one million times over, yet still make the claims they do?
Furthermore, food product marketers, for example, make tremendously misleading claims about the their product offerings. See Godiva or Lindtt and their respective gourmet chocolate claims. Last time I checked, their is more high-quality, genuine cocoa in grocery store private label chocolate bars than what Godiva and Lindtt put into their ‘gourmet chocolates’.
In the car industry, Honda practically mandates (through electronic monitoring and alarm systems) that their synthetic oil be changed at 6 months and 7,000 miles of driving. However, scientific testing at numerous labs show that synthetic oil can be changed every 12 months and at 15,000 miles or more, without any harm done to the engine. Honda and others get away with their deceptive maintenance requirements and very few say a word about it.
Lastly, I think it is ironic that a government body holds any producer to account regarding claims accuracy. I mean, if any entity in society is prone to making false claims, it is the government. Next time you hear the government table a budget proposal, track that proposal and see how accurate their revenue and spending projections turn out to be. Nothing happens to them when they mislead, yet they set up regulating bodies such as the FDA to go after personal care product producers with vigor - it’s total hypocrisy.

The two most popular are petrolatum and mineral oil. They do, indeed, work.

Perry, if you or anyone else ever needs help getting cheaper rates for health procedures, I offer my assistance. I used to work for a Canadian company that did the same for Canadians on waiting lists in Ontario. We sent hundreds of people over to the U.S., most often Buffalo. I was able to get MRIs scheduled for Ontario patients for a shade under $500, on average.
If you shop around through a health broker and pay cash, the rates are often 3 or 4 times cheaper than what American hospitals charge American insurance companies, or some of their patients. I always get at least 30% off a hospitals rates because I negotiate ‘the hell’ out of their pricing. If they refuse to bring down their prices, I tell them I wont pay my bill after getting my procedure done. This always changes their attitude. Most hospitals in the U.S. also have extra capacity which enables them to offer lower pricing.
I begged my Aunt to let me take her to the U.S., but her Canadian doctor kept prescribing her pain pills and telling her she only had migranes. When she realized she was seriously ill and wanted to get an MRI or CAT scan, she was put on a waitiing list and by the time they got her in, it was too late.
In Canada, although many Canadians wont admit it, 15% of us dont have access to a family doctor. The average family of 4 pays $16,000 per year for coverage - $4,000 per capita; and as I said 1/6th of Canadians cant get a family doctor. At least when Americans pay thousands, they actually get health care.
When the A.C.A. becomes implemented in America, the same shortages are going to be produced in the U.S. Everyone will have coverage in America, in theory, but the waiting lists will become too long and people will be forced to leave the country to get the healthcare they need.

My Aunt died while being denied healthcare in Canada. She paid $4000 in taxes for Healthcare every year and couldnt get an MRI scan in time. An MRI in the U.S. costs about $500 - $700.

If doubling of the SLES didnt change things that much, I would say you have too many ‘impurities’ in your water. Are you using distilled water? I think the 4% salt is too high and is preventing foaming as well.
Also, I believe the ph of your formula will affect the amount of foam produced Try adjusting the ph and see if it helps. A ph of 5.5 would be a good target.

Wouldnt silica be a safer alternative to plastic beads?

I have never used marshmallow root or slippery elm, but I suppose it would behave similar in fashion to how xanthan gum behaves.
When you use a mucilage or polysaccharide in water as a thickening agent, the viscosity obviously depends on the percentage of the ingredient used. When you further boil that solution, the water will evaporate more and more, therefore raising the percentage concentration.
This will result in a thicker and thicker solution, going forward, once everything cools.
These types of ingredients - marshmallow root, slippery elm, xanthan
gum, etc. are ideal environments for microbes to grow. Obviously, when
you boil the solution, it should be sterile, but if you are going to
keep it aside and reuse it many times later on, you have to make sure
that the container you are storing it in is SUPER CLEAN and that you
refrigerate the solution immediately. Even then, you will probably get
contamination within 24 hours of it cooling. So, if
you are going to store it and reuse it, I would add a perservative to
the mucilage.In a hair care product, a mucilage or polysaccharide will thicken the hair, but will leave a powdered residue buildup over time, I suppose. You might want to use a co-solvent to keep the remaining mucilage or polysaccharide on the hair from becoming ‘flaky’ once the water has evaporated after application.
In terms of ratios to use, I would start off using 0.25% and then add in increments of 0.10%, until you get the desired consistency you want.

I am saying that if we paid formulators for advice, we would get better responses than not paying. But, I dont want to pay thousands for one or two problems I face with my formula. I am however, willing to pay a few hundred dollars for specific help.
