Compare 2 columns and delete all junk.

[Uriakus]

Hi, my English is not good but I will try.
I have a reference column with products and I want to compare it with another column and delete all text that is not related to the control column.

Example...

LG G6 .................... LG G6 New promotion
Samsung C5 .......... Samsung C5 Deal offer
iPhone X ................ IPhone X Black Friday

I would like a formula that can delete from the second column al text but the names in the control column from the right.
In this example it should delete...

New promotion
Deal offer
Black Friday

And leave the names intact as the control column.

Thanks in advance.
