Greetings everyone
I was wondering if anyone in this community has had experience working with environmentally friendly surfactants (preferably of a high purity) that are commercially available. Looking forward to hearing your suggestions.
Sincerely
Dear Dr. Siam Hussain,
You can use high-purity environmentally friendly surfactants, that are commercially available:
Akzo Nobel Eco-friendly Surfactants
- AG 6202 – AG 6202 is a low foaming alkyl glucoside, non-ionic surfactant, based on a short chain fatty alcohol and glucose. It has a water content of 33 – 37% and a color value of 10 Gardner.
- AG 6206 – AG 6206 is a low foaming alkyl glucoside, non-ionic surfactant, based on a short chain fatty alcohol and glucose. It has a water content of 23 – 27% and a viscosity of 775 mPas at 20° C.
- AG 6210 – AG 6210 is a non-ionic surfactant, alkyl glucoside, based on a blend of short chain fatty alcohols and glucose. It has a pH value of 4 – 7 (1%in water) and a density of 1110 kg/m³ at 20° C.
- ALCOGUARD H 5240 – Alcoguard® H 5240 is a new hybrid bio-polymer technology for the detergents market. Alcoguard® H 5240 is a marriage of selected polysaccharides and synthetic monomers, designed to prevent scale formation in detergent applications such as automatic dishwash or laundry detergent systems. This polymer is particularly effective at minimizing filming and spotting in zero phosphate automatic dishwash formulations, and functions in the same way typical acrylate/maleate co-polymers do in laundry detergent.

The finnish tall oil soap has been used for 100 years. It contains resin acids that are toxic to fish but otherwise it is biodegradable.

Nearly all surfactants commercially available are very complex mixtures/mixes of
individual compounds. A high-purity surfactant may be produced by high-purity starting raw materials (on a laboratory scale) only. Such raw materials cannot be polymers, oils/resins etc. with quite broad molecular distribution curves of individual compounds! Your search will get even more complicated, if you focus on evironmentally-friendly products. ... but it seems, for your very special requirement/question, there is ONE product group available only, which may be produced in high purity : This would be i.e. a high-purity saturated fatty acid (stearic acid etc.) neutralized with high-purity alkali (i.e. potassium hydroxide) under very clean conditions.
This very traditional surfactant would satisfy your requirements, but don't ask me for the final price! Do you really need such a product?
