Special delicates lingerie detergent is unnecessary.
Does this sentence need commas or is this sentence punctuated correctly?
It doesn't make any sense, regardless of punctuation.
Oh -- unless you mean special, delicates, and lingerie are all adjectives modifying detergent. If so, it's an awkward and confusing sentence.
The sentence would be better if you wrote this:
Laundry detergent for especially delicate lingerie is unnecessary.
