Tide, Persil (USA version) and some others have jumped onto "hygienically clean" bandwagon.
Near as one can figure out those claims are based upon detergent in question doing a better job (in theory) on sweat and body oils.

Like many others Tide detergents in various forms (liquids, powders, pods..) all start from same base formula. Then things are added to make up the dozens of variations on offer.
This is common for many consumer products that have reached mature stage of lifecycle. Think about it; how many variations of toothpaste does any particular market require? Same for toilet tissue, washing up liquid, and so on.
To generate ever more sales and keep consumer interest, P&G like others keeps tweaking products and or coming out with variations to meet this or that perceived area of market.
Up until 1980's or 1990's you had only one or maybe two versions of Tide in either powder or liquid. Now there are three, five or more depending upon which format is chosen.
For Tide "hygienically clean" two ingredients ((Diethylenetriamine, Methyl Di-t-Butyl Hydroxyhydrocinnamate), are added that aren't always found singly or together in other versions of Tide liquid format detergents (this would include pods).
