What effect are you hoping to achieve by doing this? It will not be a fizzy drink.
The mass of the gas(es) loadable into a device of this type is extremely low, such that one inadvertant press of the operating button can result in sudden total loss of propellant and a useless product.
Pressures in excess of 140PSIG are too high for a general use aerosol (have you ever looked at the thickness of the metal on an aerosol container? Even small changes in temperature can result in large changes in internal pressure - together with a rapid increase in the potential for catastrophic failure of the container.
50/50 O2/N2 mixtures are dangerously flammable and products containing this mixture must be labelled as such. There is also the increased potential for accelerated rust (corrosion) on the metal components and oxidation sensitive ingredients in your product.

Akypo RLM45-CA is the laureth-6 carboxylic acid.

Unfortunately the brambleberry link given is a 404.

Do you have a particular reason for making your own product other than general interest?
If you want to start a small commercial line you can buy lip balm base from a number of suppliers (Google “lip balm base”). -
As well as just looking at ingredients lists, it is often worthwhile interpreting what the ingredients may have been converted to during manufacture.
A quick glance at the LOI of the product you are trying to emulate tells me immediately that the principle foaming agent is a potassium laurate based soap (lauric acid, potassium hydroxide, myristic acid, palmitic acid). The foaming propensity is enhanced by PEG-150,Laureth-6 carboxylic acid, lauryl hydroxysultaine.

Never successful.
Difficult/impossible to prevent overspray on to scalp/facial skin/clothing.
-
The LOI of Redensyl states:
Water, Glycerin, Sodium Metabisulfite, Glycine, Larix Europaea Wood Extract, Zinc Chloride, Camellia Sinensis Leaf Extract
Looks markedly like snake oil to me (or perhaps snake water, considering it’s an aqueous base.)

Is this for your face wash idea?
Stearic acid would be near the bottom of my list of choices in this type of product -probably not make it at all.

Are you using microfine/nanofine particle size ZnO and TiO2

i can try and do an HLB tomorrow for you
Do not confuse HLB and Sap Value

You could try increasing the proportion of longer chain fatty acids in your soap - this will also tend to make it more gentle on the skin.
No drastic changes needed just change from 50/50 olive/coconut to 90/10 and any proportions in between (do some experiments).
You will, of course, need to recalculate your lye:fat ratios. This may help

Note: I have not used the calculator so I have no idea if it is reliable/accurate.

There are materials that would do the job such as the currently used aerosol propellants (such as dimethyl ether, C1 - C5 alkanes) but then there is the problem of flammability (the lack of which was the main plus point of the original product).
-
The foaming agents are methyl perfluorobutyl etherand methyl perfluoroisbutyl ether. These two agents were introduced, together with hydrofluorocarbons, as “harmless” replacements for CFC.
There are now moves to ban these alternative materials as they are being shown to be just as environmentally destructive as the materials they are replacing.

What detergent will you be using in your “natural” shampoo?
In my view, gums (as a generality) for thickening shampoos range in acceptability from poor to dreadful.

When I was a starter in this game, a development manager insisted that all his staff realised the importance of having products adequately preserved.
To this end he arranged demonstrations of the microbial viability of the muck and grime found in the bottom of make-up bags, pockets, in the folds of wallets and other places dirt collected.
After a few days culture the swabs we were required to identify the organisms that had grown and their potential for causing infections and disease.
If anyone has any doubts about the necessity for antimicrobials, do a few checks yourself.
Even anhydrous products can carry spores ready to be activated when conditions allow.

Perhaps I should have mentioned that after the multinational takeover of the products the formulations fairly quickly altered to match those of the main line products of the multinational - all novelty of the stylist and my efforts lost and gone. It did save a huge amount in costs, though as the only difference between the stylist’s and the mainline product became a difference in the labelling/packaging - which equated to a 100% price premiun.

It’s probably the ambition of every hair stylist to have their own named range of products. It is extremely rare that this comes to anything.
Consider the number of hairstylists there are and the number of signature hairstylist products. You will quickly see that it is next to impossible to get anything on to the market under your own banner.
The way most hairstylists come up with signature products is in partnership with an established manufacturer - who, in turn, uses the stylists good name and reputation. Normally the initial approach comes from the product manufacturer wishing to broaden their marketplace but it could be worthwhile, if you have a wide enough reputation, to approach a manufacturer offering your good name in return for royalties. Wherther or not you have any input on the formulation of the prduct range depends on the terms of your contract.
If you do want to go on your own, be prepared for a lot of disappointment, very large costs associated with setting up (a formulation expert’s costs will be negligible compared with this), legal compliance and so on and so on.
I have worked with several “named hairstylists” in producing their own product ranges which were reasonably successful but these people were very often on TV which had a huge influence on the success of the product range. An even bigger influence of the success was when the prducts were taken over by a multinational manufacturer/marketer.

Suppliers of cosmetics raw materials, cleaning products raw materials and finished/part finished cleaning products. Also a range of perfume oils.https://atomscientific.com/
Not specifically cosmetics based but have a number of useful materials. Definitely worth a look. -

I saw this coming for a number of years and it’s one of the major reasons I retired from active innovation work (apart from my antiquity).
I could never get my head round this obsessive notion in the populace that “natural is good” and “natural is safe”. The most dangerous and toxic materials in existence are totally natural. Man-made “nasties” are feeble in comparison.

This has been the Holy Grail of lipstick formulators for very long time.
Kiss-proof lipsticks and sealants have come and gone. Few of them staying on the market for very long.
If you have a feasible idea it would be best to show it (in confidence) to a lipstick manufacturer.

Isopropanol (and ethanol) is the kiss of death to most emulsions.
1% fragrance oil is a large excess.
It is almost impossible to have a W/O emulsion at that level of water (92%).
Very unusual mixing technique and formulation. Is this your own idea?
What is the function of the product?
-
A good starting point is to check up the ingredients listing of the product(s) you are trying to copy. I don’t think you have done this.
