This Dividend King is available to investors at a once-in-a-decade valuation. This idea is especially true when the Dividend King in question is available to buy at a once-in-a-decade valuation, which is the case for consumer goods juggernaut Colgate-Palmolive (CL -0.14%) today. Here's why the company is my favorite Dividend King to buy right now. The company is the global market share leader in toothpaste, manual toothbrushes, pet nutrition at vet clinics, and liquid hand soap. This ability to invest in new growth areas and defend its market share with new versions of products makes Colgate's long-term outlook as steady as ever.
