Glycolipids (Evonik Rheance 1) as a solubliser for essential oils in mouthwash
Does anyone here have experience of using glycolipids (Rheance 1 by Evonik) as a solubliser for essential oils?
Using aniseed/peppermint/menthol blend for a mouthwash about 1.5% of the total formulation - and been using glycolipids at around 0.2% to 0.75% of the total formulation. (on tasting 1.5% essential oil blend is a bit too much, so will be reducing)
I’m dispersing the oils into the Rheance one before adding to the aqueous phase. The supplier info says glycolipids will produce a clear solution after 12 hours. At 24 hours, my solution is still milky.I understand the glycolipids can be stirred in and cold processed - or am I misunderstanding the supplier information and should be homogenising?
The remaining solution is around 20% sorbitol solution 70%, 15% glycerol, water QS to 100% (citric acid, sodium benzoate and potassium sorbate QS)
BTW - company requirements are to comply with COSMOS Natural standards for the finished product.

Please check the pH of the mouthwash. If the pH is below 5, it may become hazy. recommendation pH level is above 5.5

You might need to add more of your glycolipids.

@Herbnerd Do you have any safety assessment on the glycolipids being used? These are relatively new surfactants in the supply chain. Also how do these taste? I know the polyglycerol esters have been used extensively in food products as solubilizer-emulsifiers and have a longstanding safety profile.
