So I made a google search for most powerful solubilisers and poliglicoleum came up. The listed ingredient was polyoxyethylene (40) ricinoleyl ether. Seems like it’s between this and the Eumulgin HPS for me.

I’m trying to make a water-based perfume like that of Maison Sybarite’s range so I really want to use the minimum amount of solubiliser to a large amount of fragrance oil. I’m aware that a solvent such as hexanediol could greatly help incorporate more fragrance into formula, and I’m also aware that when using polysorbate 20 I end up adding too much and causing a ”scent-projection drop” to the product. I haven’t tried peg-40 hydrogenated castor oil (hco)nyet, and I’m also able to get peg-60 hco as well as the non hydrogenated versions… peg-60 castor oil for example. 
CB I hate perfume is another brand that makes water-based perfume. They seem to be a popular endeavour even though formulating with water is difficult to pull off (I’m still very interested in doing so). 
MPG is monopropylene glycol and dpg is dipropylene glycol.
I know this post would seem more suitable for basenotes but people over there seem more fixated on using oil-based or alcohol based perfumes, with little experience in the field of using solubilisers.

[LuisJavier]

Does anyone have any experience with very powerful solubilisers like those above? 

[LuisJavier]

Very useful clarification. I agree on use of a glycol to boost preservation. I think I will go for pentanediol or hexyl glycol.

In the UK, Adam equipment and Ohaus scales look good

Benzene is a recognised carcinogen. Strange that some people would add it to skin-lightening applications.

Thanks a lot Pharma. I had no clue that the black stains could be removed. I’ve bought some 9% HP solution and will try that by rubbing it in with a cloth or sponge. If that doesn’t work, I’ll try the ammonia solution too. Just to be on the safe side, even with the 9% HP solution, I think it might be best for me to still leave the bathroom door open and left unused for about an hour. 

[LuisJavier]

So I looked for some hydrogen peroxide online and found 3/6/9/12% solutions in ultrapure water. Would a 3% solution be enough for removing the sealant which turned black in colour?

[LuisJavier]

You’re welcome

I use 70% iso at home and at work. Hydrogen peroxide is only for cleaning really nasty stuff like the black algae which form in the edges around the bathtub.

I have this black stain problem on the edges around my bathtub. Great to know that hydrogen peroxide could work. Do you recommend something better for this job? How do you recommend I go about using HP to remove the stains? Rubbing/swiping small amount using cloth? Do I leave it in after it has been rubbed/swiped or do I simply rinse with water after, say, 5 mins?

I meant adding colour to a moisturiser

[LuisJavier]

Seems like far too much veg. oil in a formula to me. Also the stearic acid probably imparts a thick feeling that stays on the skin. Look into using glyceryl citrate/lactate/linoleate/oleate as the emulsifier for a very soft cream?
 Where are your preservatives?

[LuisJavier]

AHAs. Makes sense. Glycolic, lactic, mandelic etc

[LuisJavier]

In that case I think I’ll stick with IPA. Far less hassle and less hydrogen peroxide on my gloves/hands when cleaning. 

[LuisJavier]

Hydrogen peroxide vs IPA 70%? Does the HP evaporate quickly?

[LuisJavier]

A very interesting read there Doreen. Thank you. I f you check out the website url that I linked, you will see that phenoxyethanol seems to have issues with non-ionic surfactants too. I think I may stop using Arlacel 165 and switch over to glyceryl stearate and sodium stearoyl glutamate.

[LuisJavier]

I was quite puzzled because the link I shared seems very much like a reputable source yet they say that non-ionics can inactivate phenoxyethanol… maybe % of the non-ionic surfactants is major here.

[LuisJavier]

Does anyone know?

[LuisJavier]

Very true. I really appreciate that aspect of the glycols.

[LuisJavier]

I would have to order the sorbitol first… could you let me know the effect? In any case, I think the glycols are what I will use. They seem considerably cheaper than sorbitol.  

[LuisJavier]

Thank you Mark

How much was the Tinogard TS and TT quoted to you, if you enquired?

[LuisJavier]

wow! The cheapest I’ve found BHT so far in the UK is at around £65 per kilogram. Supplier: Pell Wall

[LuisJavier]

I just remembered a some minutes or hours ago that BHT is also an antioxidant. I do not know the price of BHT so I do not know whether the Tinogard series of antioxidants are more economical than BHT. In regards to antioxidant efficacy, I am very curious to see how the Tinogards fare against BHT.

I’ve been struggling to find a supplier of small quantities of hexanediol. I didn’t know that Methyl Gluceth-20 was a humectant; I thought it only functioned as an emulsifier. I might chase up a producer company for some hexylene glycol. Pentylene glycol seems good too although one of my suppliers only offers the natural version which is unattractively expensive in comparison to propylene glycol. Also I tested DPG and I find it is tackier than MPG.
