The 'Grey's Anatomy' actor - whose second fragrance will be out in November through home retailers Avon - designed the scent to heighten romantic feelings between the wearer and his partner.
He said: "It's about the intimacy of two people and the strength you get in a relationship. I thought, why don't we just go with 2 and make this about being a couple."
The affordable cologne will be a mixture of "mandarin, nutmeg, spiced wood accord and patchouli" and is to be marketed at a "budget-friendly price of $35 for a 2.5oz. bottle".
To reinforce the message, the aftershave's advertising campaign features a photograph of the 43-year-old actor and his wife of 10 years, Jillian Fink.
Last summer, Patrick's first signature fragrance, Unscripted, became a bestseller with Avon.
Patrick is not the only Hollywood hunk to add his name to a scent.
Two weeks ago, 'Factory Girl' actor Hayden Christensen was revealed as the face of Lacoste's new fragrance Challenge.
