We DIYers can get pretty much the same ingredient (from loads of different suppliers) under the INCI name of sodium cocoyl isethionate, also often called Baby Foam due to its gentleness. The "cocoyl" part indicates it is derived from coconuts. Lauric acid makes up something like 50% of coconut fatty acids (by far the largest proportion)... and this purified version is what is used to make the sodium lauroyl isethionate listed on the Dove bar ingredients.
The "one quarter moisturizing cream" claim, what about that one? So, it's not actually moisturizing lotion. Obviously right? It's a cleanser bar, not a lotion. However there is some truth to the claim. There is an ingredient called stearic acid in Dove, which is a really good moisturizer that is an ingredient in plenty of moisturizing creams, and just happens to work really well with sodium cocoyl/lauroyl isethionate! It adds moisturizing without ruining the lather, which is what most moisturizing ingredients would do. And what percentage do you think they use it at? I'd be willing to bet it's 25%.
As a soap-maker, the people who know I also love and use Dove think it's pretty ironic... and maybe even deceitful... that I'm such a two-timer with my bar cleansers. Frankly, each has its benefits. I don't find that Dove removes deodorant really well, but soap does. Soap can be made way prettier than a syndet bar any day. And since I make soap, I can make it smell like whatever I want. I love the smell of original Dove, and some of their new fragrances are pretty great too. I love the feel of the lather and the gentleness of Dove. And I love the fact that they offer a fragrance free sensitive skin option that is affordable and readily available to all of us with dainty hides (and "fragrance sensitivites," though I have my doubts that many of the people who claim this affliction would use Dove, made by eeeevil Unilever, after all...).
So how am I to reconcile my conflict of interest? Make a syndet bar, of course!
I've had some sodium cocoyl isethionate for quite a while (an 85% active variety... it comes in a wide range of concentrations and formats, with or without pre-added stearic acid, so you have to pay attention with this ingredient), but all of my previous experiments were dramatic failures due to the fact that I thought it was supposed to melt into a clear liquid... it's not. If it is being put in something with a large percentage of other liquid surfactants, it will fully melt into the liquid. If you are making a bar product or cream cleanser with less liquids in it, it will melt into a white paste. Don't try to get it clear and liquidy with ever-increasing stirring and heat... it will burn, it will stink, and there will be burnt orange bits in the thing that you make. Ask me how I know this.
So I analyzed the ingredient lists of Dove's sensitive skin bar and their pear-and-aloe scented GoFresh variety (which are a little different, but have the same key ingredients, and when there are different ingredients, you can match them based on the function they fulfill in the bar). I used this information to come up with my own recipe, with the sodium cocoyl isethionate and stearic acid making up over 75% of the ingredients. A few bits of liquid surfactant, water, dipropylene glycol, sodium chloride (i.e. non-iodized table salt), tetrasodium EDTA, colour, and fragrance oil finish it off.
It turned out quite nice. I have only used the residue so far to wash out the beakers and measuring cups used to make it, and washed my hands once, but I think I like it! So am I breaking up with Dove? I dunno, probably not. It's so damn cheap, it's probably way more expensive to make it myself. But we'll see how it goes. :)
