Also Henkel's the primary owner of the Persil brand.
You're also probably aware that Persil is primarily a Henkel brand. Lever Brothers (now Unilever) acquired the rights to it in several markets: The UK, Ireland, France, New Zealand and possibly one or two others.
In France, Unilever doesn't use Persil as their main top of the line brand, but they have it in a sort of nature inspired range that doesn't exist in the UK and Ireland. It's possible because Persil translates as parsley in French, which isn't necessarily the ideal name for a detergent. Although, Henkel sells Persil very successfully in Belgium and Switzerland, both of which have large French speaking regions.
Persil in most other markets, now including the United States, is a Henkel product.
Unilever has long used he idea of symbolic marketing and local brands. The most famous example of this is the "heart brand" ice cream. In the UK it's Walls, in Ireland it's HB, in France it's Miko, Frigo in Spain, Good Humor in the US, Streets in Australia and NZ, Langnese in German and so on.
Or the Axe brand deodorants called Lynx in the UK and Ireland and a few markets.
They do the same with with Cif, which originated in Franve in the 1960 and is known as Jif, Vim, Viss and even Handy Andy in some markets.
Unilever tend to develop symbolic brands with a common product, logo and packaging design and then localise them with a name change.
So for Omo (Persil and Skip) they have the "splat" logo.
Ice creams : the heart brand.
Axe (including Lynx) - same logo and packaging designs and products.
Cif : (multiple names) - logo, packaging and typeface are common.
All of those products are centrally manufactured in a number of sites around Europe and arpjndbrhe world. They have a fairly sophisticated supply chain that keeps their costs where they want them Ans still allows them to localise.
Proctor and Gable and Henkel do similar.
So do all the big consumer products manufacturing companies.
