I have some liquid soap that I have made that has some cloudiness in the top 1/2 inch or so of the containers. I have researched the issue and found two possibilities. One might be that even a slight amount of "superfatting" the oil phase may cause this and that "superfatting" is not recommended in this type of formulation. The other option might be that the cloudiness is coming from the fragrance not totally being emulsified into the liquid soap. My formula is not "superfatted" and takes into consideration the 90% of the Potassium Hydroxide. Now, another factor is pointing toward the fragrance issue and that is that a couple of the scents (fragrance oil) have no cloudiness in them! Here is the typical ingredient list so that I make sure there aren't any other possible issues!
Cocos Nucifera (Coconut) Oil, Oleic
Acid, Ricinus Communis (Castor) Seed Oil, Potassium Hydroxide, PEG-150
Pentaerythrityl Tetrastearate, Glycerin, fragrance, Caprylyl Glycol, Phenoxyethanol,
It was suggested using polysorbate
20 for the fragrance issue. Do you have any other options or suggestions?Amount listed were 1-20% from the MSDS sheet. Do you have Any suggested amounts or ranges?Is it better to do this when product is still warm from production or can this be used at room temperature?Should the fragrance and Polysorbate 20 be mixed together before being "homogenized" into the mixture?
Thank you in advance for any suggestions or information you can provide!
