DHA/ARA and single cell oil

[formulaconfusion]

I’ve been researching formula a lot. I’ve come across a lot of info about single cell oils and I wondered does anyone know are the oils in uk formula milks Hexane processed ?
I can’t choose between HiPP Organic or aptamil.
Hipp seems to have c.cohnii and m.allona oils which I thought were just plant based but are actually from algae and fungi
Aptamil just lists single cell oil and it’s bothering me a bit - does anyone know whether these oils are Hexane processed in these formulas or not thanks
