Add Urea to your formulation - about 2% should do, then test, place your product into a test tube into ice with a thermometer into your product. As the temperature decreases you should not not a cloud formation in the test tube. The issue with Urea is that it will also decrease your viscosity, but it is a quick and cheap option to resolve your issue. Please add CIT/MIT to your formula as preservative.

You are looking at Siloxane based chemistry - read as much as you can about it, then study the evaporation rate of various solvents, it is important as you’d need a very specific volatility of the solvent to cross-link to a vehicles surface.

Hi there,
For phosphonate Briquest 543-25S, for readily biodegradable sequestering agent try Dissolvine GL 47. Why didn’t add enzymes to your laundry liquid?
-
I see that you are aiming at a very biodegradable formula, nice - try to read up on Berol 611 (readily biodegradable raw material). For high-end dishwashing liquids you aim at a active percentage of about 28%, interim formulations at about 16% active. Many companies still use Sulphonic Acid/SLES based formulations which is easily thickened by using salt. You’ll probably will break the viscosity if you water-down your formula.

Hi there,
Please can you add UREA to the formulation (this should clarify your product although it will decrease the viscosity a bit. Please remove the Sodium Benzoate and try to obtain a blend of CIT & MIT if you can. When you obtain the correct preservative then also allow for the product that when diluted that the preservative is still active within the suggested active percentage in your formulation. Always check your pH it is important - try for a pH of about 5 @ 25°C
-
pH is the measure of alkalinity and acidity of a lets say a liquid - low pH indicated acidity and high pH indicates alkalinity - pH is measured from 0 (acid) to 14 (alkali) and pH neutral is 7. Human skin pH is at about 5 - so when you formulate cosmetics it is something to be aware of.

This is brilliant!
Did you consider formulating in PVOH film - in that way you can move away from plastic and place your already very eco-friendly product into a film that dissolves in water - like a laundry pod.

I’m glad to assist.
I’ll stick to the LAS/SLES based formulations - this is anionic based, meaning you’ll have a negative charged molecule to aid as a degreaser. Also look at incorporating D-Limonene, although it is a allergen it increases your degreasing capability within your formulation - the other important thing that I’m missing in your formula is a chelating agent - the water hardness plays an important roll as it will interfere with the detergent’s ability to fully capitalize on the detergent’s cleaning ability. So, make sure you use purified water from the start - this is obtained by either reverse osmosis or deionized water, then with the addition of a chelating agent so, when you use your product and mix it with hard water the efficacy isn’t hampered due to hard water being used.
For a chelating agent look: Tetrasodium Glutamate Diacetate. Dissolvine® GL-47-S by Nouryon. It is a high purity, versatile and readily biodegradable chelate based upon L-glutamic acid, a natural and it is a renewable raw material.
Then regarding your preservative - try to incorporate a blend (render a broad spectrum preservative (NS not for use in cosmetics), I use a chemical called Actichem LA 1220, this is a blend of 5-chloro-2-methyl-4-isothiazolin-3-one (CIT), 2-methyl-4-isothiazolin-3-one (MIT) and Bromonitropropane diol (Bronopol) - you’ll only need to use 0.05% within your formulation.
