【Benefits of Adding Honey to Soap】
"The secret of my health is applying honey inside and oil outside," is a quotation credited to Greek philosopher and physician who lived to be 109 during the years 460-370 BC. It sounds like Democritus would have gotten along well with soap makers—though he could have used some convincing him that honey was good to use on the inside and the outside.

Honey's Humectant and Antimicrobial Qualities
But history aside, honey is actually a pretty remarkable liquid. Honey is primarily known for its humectant—a compound that attracts moisture to itself and helps retain the moisture—and antimicrobial qualities. Naturally, humectants are wonderful oil additives to lotions, scrubs, and other skincare products.
Honey's unique chemical composition also makes it an effective antimicrobial agent. People have used it to treat minor burns and scrapes, and for aiding the treatment of sore throats and other bacterial infections for centuries. If you just want to use it in some tea or on a muffin, honey contains antioxidants, trace amounts of vitamins, so it’s better for you than just plain sugar.

Honey in Soap Making
Honey is also a wonderful additive to soaps, and you don't have to be a beekeeper to use it. It imparts a light, warm, sweet scent, the added sugar content helps increase the lather, and acts as a humectant. We generally use about 1 tbs. per pound of oils and add it at a very light trace.
You want to make sure it gets completely incorporated into the soap before your trace gets too thick. Honey will turn your soap a light tan color. This, similar to what occurs when you use milk in soap, is from the chemical reaction with the extra sugars in the soap.
