@thebrain I was reading this and I have exactly the same problem. Lumps floating at the top of my shampoo. How’s your latest progress?

Thanks @Bobzchemist for your recommendation.

I’m getting Phenonip, hopefully it will solve my preservation problem as my ingredients are wax, oils, butter, and water.

Thank you for all your advice, really apprecate it.

 I tried using methyl paraben in water phase and propyl paraben in oil phase. For each type of paraben, I used less than 1% of total weight (oil + water phase), so total paraben is about 2% of total product weight. However my product only last for about 2-3 weeks..

I don’t cook up my water phase because I’m still trying in small batches, so what I do is I use a precook water and mix it with methyl paraben.

I’m using soya lecithin as my emulsifier.

Is there anything I did wrong? Or do I need to increase my paraben?

Thanks in advance!
