There may be some starting formulations of interest to you on the Lubrizol website

Thanks chemicalmatt for the information

Thanks for the suggestions! I will give them a try.

You could try a glycol ether solvent such as Dowanol DPM (INCI: PPG-2 Methyl Ether) if you want to stay away from alcohol. I have seen this used in an alcohol free perfume formulation with PEG-40 HCO to help solubilise the fragrance. From memory it was used at about 5%.

Can you add some ethanol or other water soluble solvent to help solubilize your active?

These tables might be useful for you

Have a look at Dow Cornings website. They have starting formulations for all sorts of automotive polishes.

Some basic etiquette like introducing yourself, not using capital letters, being polite when asking questions,etc would be good to include in general forum guidelines.
Other guidelines might include:
If asking for formulation help, give some information about the formula rather than just a vague description of the problem. eg. “Help - my lotion separated when I added xxx raw material” is not going to get many responses other than “what else is in the formulation”. Whereas “Help - my lotion separated when I added abc raw material. The lotion also contains x,y & z. I added abc to the cool down phase” is going to get more responses. You don’t need to give exact percentages of each ingredient if you don’t want to, although this may help you get the answer you require.If people respond to your request for help. Make a post in the thread thanking/acknowledging them.

@millachemist I am also seeing the pattern hence my advice to the original poster to slow down and learn something. I won’t be offering any further help.

Why are you making 10 litre batches of products that you obviously have no experience with? Where are you getting your starting formulations? A quick google search of “carageenan air freshener formulation” gives a number of formulations from reutable suppliers that would give you a great starting point.
I am assuming that when you refer to “sulphurnic” you are actually referring to sulphuric acid. I have no idea why you would include that at all in this formulation. You have 15% fragrance in your formula with no solubiliser (surfactant) so it is no wonder that you are getting separation. Most fragrances are not water soluble and in the couple of starting formulations I looked at the fragrance concentrations were at around 2.5%.
Looking at your other posts it is clear that you are trying to make large batches with no experience and really just wasting your money. My suggestion would be to slow down and learn something about the products you wish to make, look for starting formulations, learn about the function of the raw materials you will need to use, start with small test batches, and then eventually after much trial and error come up with a product that will be suitable for your needs. Even experienced formulators would follow a similar procedure.

The preservative ingredients in this formula are probably the caprylyl glycol and the Honeysuckle extract.
Caprylyl Glycol has some antimicrobial activity and honeysuckle extract contains ‘natural’ parabens.

Do you have any information on what chemical/s in the leaf are the active constituents? You will need to extract these actives into a useable form (or purchase an existing extract of this plant if it exists) and then create a deodorant formulation based on this extract. You will then need to test the efficacy of your product as a deodorant. I am not sure of the UK regulations but I am assuming that if you are creating a new extract there will need to be some type of registration and safety testing.
This is assuming that you are planning to make a commercial type deodorant and are not just planning to sell leaves to people.
Hope this helps

When formulating it is advisable to start by making small batches (100 to 500g) to test a formula rather than trying to make 5kg straight away. Also when providing a formula for comment/assistance it is easier for others to comment if it is given in percentages and with the INCI names.
Definitely check out swiftcraftmonkeys blog, she has a lot of very useful information for people who are just starting out with formulating. I would advise trying to make some of the formulas that she has on her blog before starting to create your own formulas.
Cetrimonium Chloride is good for detangling.
Hope this helps.

New Directions Australia sells 100cs dimethicone. It is not the 6cps you are currently using but it might be good enough.
The only way to tell if replacement ingredients will work is to test them.
-
Perhaps the easier thing to do would be to find a different solubilizer. Maybe you should ask your supplier of the polysorbates what they would recommend.
-
Have you considered methylisothiazolinone or benzisothiazolinone or a quaternary preservative like benzalkonium chloride?

I have used Plantapon SF in a body wash with CAPB as the secondary surfactant. It is recommended by BASF for facial cleansers so there should be no issues with it being mild enough. The only issues that I came across were that it is not a great foamer (ok but not sulfate type foam) and that the final formulation was not very thick. Not sure if either of those things matter to you.

Hi Everyone,
I am a product development chemist working for a small company in Australia that makes a wide variety of cleaning products and a smaller number of personal care type products. I look forward to both learning and sharing on this forum.
