Polemic ingredient C13-15 Alkane

Hi I live in Brazil and recently bought some newly released local products that claim to be ok for no poo. But they contain C13-15 Alkane and it's been causing polemic, since some people noticed it's not a water soluble ingredient. Is this really an ok ingredient, or will it cause build up? I wonder if anyone can shine some light on this issue.

Here's their complete ingredient list:

    I don't even see C13-15 alkane in the cowash ingredients. In the 2nd list, it appears with the preservative, pH adjusters, and fragrance. This means there is very little of it in the combing cream. Yes, it's an oil, but there are several others in the product also. Here is a webpage that explains how it's used: https://www.makingcosmetics.com/Squalane-Light_p_1032.html

    I'm not sure what the laws are in Brazil, but if they're anything like the  USA, then companies are required to list ingredients in order of concentration (how much of it is in the product).  See here for a good explanation of ingredients lists and what makes up the majority of a product: http://thebeautybrains.com/2006/06/beauty-armor-how-to-read-an-ingredient-list/

    In short, the first 5 ingredients after water are most of what goes into a given product. Those listed closer to the end are present in miniscule amounts.

    If I was using this on my own hair, I wouldn't worry about this ingredient. If I experienced buildup, I would low poo (use a sulfate free shampoo containing Cocamidopropyl betaine or cocobetaine). In terms of buildup, I would point to the polyquaterniums and/or oils first. Not everyone has issues with polyquaternium buildup, but if you do, a shampoo containing C14-16 olefin sulfonate should take care of it.

    In terms of curly girl method /no poo, the only "forbidden" ingredients are sulfates in shampoo and non-water soluble silicones (end in -cone, -conol, and -xane) in any product. Water soluble silicones start with PEG- or PPG-. If we couldn't use any non-water soluble ingredients, then we couldn't even use oils (coconut or argan, for instance) or butters (like shea), when in fact they're actually good for hair when used in moderation.

    Hope this helps!
