Water based does not, in itself, suggest a spray but, never mind that.
A simple “natural” water based spray could be built around a solvent mix of ethanol, propanediol and water. The ratios of each to be worked out according to the properties of your natural fragrance.
Propanediol (Zemea, Tate & Lyle, DuPont) is derived from corn by fermentation.
Ethanol is usually naturally sourced.
I am unable to suggest a manufacturer for your area as I am in the UK.

This may be of interest:
Recently, Technavio reported the personal lubricant market will expand at a CAGR of ~7% between 2016 and 2020. Water-based lubricants in particular are forecast at a 6.75% CAGR for the same time frame. This projection is higher than the anticipated CAGR from 2017–2022 for global skin care or face cream, at 4.7% and 4.9%, respectively. What’s behind this rise?
The ‘What’
Mynewsla.com discussed
this Technavio report in depth, attributing the anticipated expansion
to a broader acceptance for products to enhance sexual health and
experience. Interestingly, the report added this segment has been
growing since the 2008 recession, when people spent more time indoors
(*wink*).Additional drivers include a growing awareness for the sensory
benefits personal lubricants can provide. Attractive websites,
educational content and search engine-optimized marketing are also
influencing purchase patterns, especially since consumers of products in
this segment seek anonymity, privacy and convenience.The ‘Where’
In 2015, the personal lubricants market was led by APAC due to large
customer bases in India, China, Japan, Singapore, Indonesia and
Thailand; this trend is expected to continue through 2020. High Internet
penetration is also responsible for an increasing demand for sexual
wellness products in these countries.The ‘How’
As mynewsla.com reported, silicone-based lubricants come out
on top due to their long-lasting moisturizing properties, which are
used by an increasing number of women who experience vaginal dryness.
However, they can be stickier and messier than oil- or water-based
lubricants, and are reportedly not compatible with silicone sex toys.Water-based lubricants have been available for years and are
compatible with condoms but some of their ingredients are suspected to
cause irritation. In contrast, oil-based lubricants, which are primarily
used in developing countries, are not compatible with latex condoms.
Could this pose a market opportunity?‘Shear’ Pleasure
Then again, whose to say “sticky and messy” is a bad thing? As one study from
the Centre for Industrial Rheology demonstrates, broad technical
differences exist between equally successful lubricant brands.Here, the rheology and bio-tribology of three personal lubricants
were assessed: brand A, described as “slippery,” having “good glide” and
“light, intimate feel”; brand B, having “poor glide,” “stick/slip” and
being “silky”; and brand C, described as “thick”, “heavy” and “sticky.”Three parameters were tested: viscosity under shear, elasticity under
shear and frictional force over varied sliding speeds. Results showed
major differences in product behavior, revealing brand success was
driven more by consumer behavior and preferences.All in all, it seems market researchers have a good feeling for growth in this most personal of personal care categories.

You haven’t defined the type of air freshener you want. Is it a gel? a spray? reed diffuser? cellulose pad? ? ? ?
It is difficult to suggest a manufacturer as most air freshener products are made in-house by such as SCJ, P&G, Benckiser and such (these people do not normally produce under contract). Also, taking this into consideration, it is very, very difficult to enter the A/F market.
Are you in the UK (as your moniker suggests?)
-
There are numerous types of air freshener. Which in particular are you interested in?
How “natural” do you want it to be?

BHT is an antioxidant, not an antimicorbial preservative.
Cyclomethicone is a silicone material and has little or no preservative properties.What you need to do (and may be you are now doing that) is to research the fundamentals of cosmetic (lipstick) formulation. Being overwhelmed will result in you getting nowhere - or perhaps even going backwards.
It isn’t as complicated as you are making it out to be. Just take things steadily and learn, don’t just absorb things by rote without any understanding of what you are doing.
If you are intending selling your creations, make certain you are fully up to date with all necessary legal requirements. There are a lot, no matter where you are located.
Don’t expect to be able to sit back and live a life of luxury by creating and selling your own cosmetics. Things just aren’t like that. To be successful going it alone requires a lot of hard work and it often results in a lot of disappointment. There aren’t many in this business who enjoy a Champagne lifestyle.

The active detergent matter is very low and it is doubtful that you will achieve a viscosity matching a reasonable quality dishwashing detergent.
I feel it would be worthwhile you re-examining the whole concept of this product.
-
Quantities of each? Do you check for neutrality of the mix after adding the NaOH? An excess (or deficiency) of NaOH can influence the viscosity of the resultant mix.

PEG-40 is polyethylene glycol. The 40 is an indication on the number of oxyethylene (-OCH2CH2-) groups are present per molecule.
PEG-40 hydrogenated castor oil is castor oil which has been subjected first to hydrogenation to reduce the glyceryl ricinoleate moiety to glyceryl hydroxystearate then reacting that with sufficient oxyethylene (ethylene oxide) to form a polyoxyethylene chain of (about) 40 units per molecule of glyceryl hydoxystearate.
Polyethylene glycols are subject to two nomenclature systems, one derived from the average chain length of the (-OCH2CH2-) groups per molecule and the other derived from the average molecular weight of the p[olymer chain - in the cases under consideration here PEG-40 has an approximate molecular weight of 2000 - thus in other industries it goes under the name of PEG-2000 or, particularly in pharma, Macrogol 2000.
It should be remembered as well that the molecular weight system is also current in cosmetic nomenclature as instanced by PEG-6000 distearate (commonly used name) has the INCI = PEG-150 distearate.

peg-7-glyceryl cocoate - there is no real substitute for this material. If you are unable to obtain it, a near equivalent is PEG-6 caprylic/capric glycerides (Softigen 767) but, if you are having problems obtaining the first material, you are likely to have similar problems with the second.
Benzyl alcohol is present as an antimicrobial preservative. There are lots of materials which could replace it.
PVP K30 is the material that provides the “hold” in a pomade.
-
You have not revealed your latest formula so we are unable to comment or make suggestions how to thicken.
-
Please be aware that PEG 40 is very different to PEG 40 hydrogenated castor oil (PEG 40 HCO).
All nonionic surfactants affect certain (usually oleophilic) preservatives.
-
Never found PEG-7 glyceryl cocoate as versatile a solubiliser as PEG40 HCO.
-
Personally, I’ve never been very enthusiastic about polysorbates (or their sorbitan ester precursors).
There may be some negative with polysorbate 80 in that it is an oleate (therefore unsaturated) but that should not affect its general use.
The most common solubiliser suggested by the companies I’ve worked in has been PEG40 HCO but, all in all, I don’t think there is much to choose between them.
I’m not sure of current pricings - this may have an influence on your choice.
-
Just curious. No actives in this serum apart from the SPF?
When you’re selling dreams, what else is needed?
-
Using the fresh plant will show how slimy and sticky fresh aloe juice/pulp really is!
Cucumber and melon are much more pleasant - and easily available at the greengrocers.
-
Like you, I have never been convinced of any positive effects obtained by aloe. One thing I have used it for, with advantage, is a soothing application of a stripped aloe leaf to minor burns - but a similar effect is obtainable with a sliced cucumber, a piece of melon or even a wet cloth.
If you feel obliged to use aloe at your “customer’s” insistence then you can obtain aloe powder or concentrates which are added near the end of processing thus avoiding adverse temperatures.
-
What is the origin of the formulation you are quoting?
Benzyl alcohol at that level seems excessive.
Is it PEG 7 you are referring to or a derivative like Peg-7-glyceryl cocoate? Similarly with PEG 40 - is it that or a derivative such as PEG-40 hydrogenated castor oil? Both of these are profoundly different in their effect.
Beeswax will most likely have a negative influence of the product.
-
Coconut oil in the amounts you are contemplating will defeat the objective of a shampoo - that is to clean the hair. Glycerin at 9% seems excessive - why are you using that large quantity? Likewise with guar gum.
Citric acid is not a preservative at the levels that would be considered reasonable.
I think it would be advisable for you to check on and consider the LOIs of commercial products rather than proceeding in the blind way you seem to be going at the moment - or to use the services of a professional formulator.

If you think that heavy metal contamination is coming from your manufacturing plant then it should be incumbent on you to correct whatever is the cause.
Otherwise, providing you have the correct certification, you should not need to carry out analyses yourself.
Setting up a laboratory to analyse trace metals is an expensive and unnecessary overhead.
-
Amorphous silica (as used in toothpaste) also acts as an efficient suspending agent for other solids in the mixture.
With all due respect, I feel that you need to learn a lot more about the products you are contemplating and their ingredients before you go much further in formulating a product.
Remember that the toothpaste marketplace is dominated by some extremely large multinational companies who employ numerous experienced formulators. Unless you have some revolutionary concept, the chances of entering this market are very slim.

That number of tubes is the work of a few moments on a standard filling machine. The setting up and clean down would most likely take much, much longer than the filling operation.
Is this a request for a trial run or the sum total of your requirements? If it is for a trial then I am fairly sure that you should get a positive response. If it is the total requirement, I think you may be restricted to hand filling yourself.
-
In the formulation you have given there is no PEG-7 nor benzyl alcohol.
Following your later post, I don’t see any beeswax.
The percentage formula totals 93.6. What other components are there?
-
Heavy metal contaminants are usually detailed in the certificate of analysis from the manufacturer/supplier of the material in question. If not, then demand this, or at least a declaration of limits, from them.
-
With the sparse information offered it is impossible to give a meaningful response. What other components are present? The amounts?

Are these thermal water aerosols “bag-in-can”?
This is the only way I can see that you can gain any reliability with compressed gas.
