Preservatives for serum(clear gel)?
Water and Phenoxyethanol and Ethylhexylglycerin makes milky sollution.
_________
I increased Glycerin and propylene glycol or used peg40 hydrogenated c.o.
However, I am still not happy with the product. it is milky.
*I havent waited to see if it settle down in a day or two. Probably it will become clearish
Any suggestions? Thanks

However, is it anything else I can do? for example, I see this formula
The Ordinary Hyaluronic Acid 2% + B5
Aqua (Water), Sodium Hyaluronate, Sodium Hyaluronate Crosspolymer, Panthenol, Ahnfeltia Concinna Extract, Glycerin, Pentylene Glycol, Propanediol, Polyacrylate Crosspolymer-6, Ppg-26-Buteth-26, Trisodium Ethylenediamine Disuccinate, Citric Acid, Ethoxydiglycol, Caprylyl Glycol, Hexylene Glycol, Ethylhexylglycerin, Phenoxyethanol, Chlorphenesin -
@ngarayeva001 unfortunately - Germall Plus (Powder) - European Union (EU) - Not to be used in body lotion and body cream :'(

Germaben II is an option too, but it is misbehaving with some ingredients and gets cloudy. I know it does with some cationic material and electrolytes. What else is in the formula?

Water 68.05% Glycerin 10.00% Preservative ?? 1.00% Propylene glycol 10.00% SepimaxZen 0.25% Alpha Arbutin 0.50% VitC3GlycAsc 10.00% hialuronic acid 0.20% Water 77.05% Glycerin 10.00% Preservative 1.00% Propylene glycol 10.00% SepimaxZen 0.25% Retinol 0.50% Hyaluronic Acid 0.20% Ceramide 1.00% I have tried Phenoxyethanol and (Phenoxyethanol and Ethylhexylglycerin) This is what I have in stock at the moment and both are giving me a slightly hazzy solution if I add SepimaxZen at the end and wait 8 hours.
or it is very milky if I add all ingredients(mix) and at the end add preservative and mix.

Update: I have ordered 2 preservatives to test and see if I am going to get a more clearer solution/serum.

1.Sodium benzoate & Potassium sorbate
2. Dehydroacetic acid & Benzyl alcohol (GFecosafe / Preservative Eco equivelent) -
