Odd soap additive purposes?

[missybee]

I recently tried out a newish soaper on etsy and the ingredient list is as follows:
Olive oil, water, coconut oil, palm oil, sodium hydroxide, yellow mica (Titanium dioxide,yellow lake 5,hydrogenated polysobutene, palmitic acid, phenoxyethenol, benzoic acid),ultramarine pink, ultramarine blue,yellow 6 lake, mica, iron oxide

Phew.That's a mouthful. It's handmade soap but what is the purpose benzoic acid, palmitic acid, phenoxyethenol, and polysobutene?I also wonder why they are separated in parenthesis?

I think they are listed this way because she is adding one item and that is the list of ingredients in it. Seems a little weird though ~

The (Titanium dioxide,yellow lake 5,hydrogenated polysobutene, palmitic acid, phenoxyethenol, benzoic acid) are the ingredients of the yellow mica. Mica is white or colorless. To give it color, pigments & dyes are added. The parentheses indicate that these ingredients are for the yellow mica.

Yep, exactly what MissMori stated.

I don't see how something like palmitic acid would be in colored mica.

Then again,I've only ever purchased things from TKB trading. They just use mica,oxides,ultramarines in every mica colorant I've ever seen.
