Let's start with our emulsifier. Incroquat BTMS-50 should be your first choice in emulsifiers for drier feeling lotions. It has what's called a "powdery" feeling on your skin, and it'll condition as well, so that's a bonus. It can also act as the conditioning and moisturizing ingredient in oil-free moisturizers. Polawax, e-wax, and most of the combinations we can use in the HLB system will all feel much greasier than BTMS-50.
We should also consider the oils we're using to make our lotions feel more powdery or dry. You'll want some drier feeling or astringent oils, like hazelnut, macadamia nut, or grapeseed oils. If you want something light, consider fractionated coconut oil - it's not low on the greasiness scale, but it rubs in well and will feel very light on your skin. Or consider the exotic oils. Most of them contain a lot of tannins and will feel dry, like evening primrose, borage, cranberry, pomegranate, and so on. They're more expensive than regular oils, but you won't need much.
You'll want to choose mango butter or kokum butter, as both are considered astringent, although they'll both feel greasier than any oil you choose.
And you'll want to consider some esters. 2% IPP or IPM can make a world of difference in your lotion - it's considered an ester that makes other oils and esters feel less greasy. You can go as high as 5% in your lotions, but I would find that way too non-greasy for my tastes!
Or consider some esters. Cetearyl ethylhexanoate, C12-15 alkyl benzoate, and ethylhexyl palmitate are all considered low greasiness esters. And they all feel very light, which is a bonus.

If you're looking to create a barrier, consider using dimethicone or allantoin instead of cocoa butter. Cocoa butter, although lovely, will add major greasiness to your product. Consider using 2% dimethicone as the barrier ingredient and 2% cyclomethicone to offer a more powdery feeling to your product. Using 0.5% to 1% allantoin in your heated water phase can add a huge amount of barrier power to your product, but make sure you dissolve it well!
We need a humectant here. I'm going to use honeyquat at 3% to offer some conditioning and humectant properties, but you could use 2% sodium lactate or 2% sodium PCA. I wouldn't use glycerin here as it could make it feel a little sticky, and we're trying to make something that feels lovely and powdery, not sticky. If you want to use sodium lactate or sodium PCA, add it in the water phase and ignore the part about the honeyquat in the cool down phase. Add 1% more water to the mix to compensate.
Finally, I'm going to add cetyl alcohol to this lotion to give it some glide without tons of greasiness. If you wanted to make this into a cream, you could use stearic acid to give it more body. If you wanted to make this a lighter lotion, I'd suggest using cetyl esters, but don't use vanilla fragrances with it! You could also use cetearyl alcohol, but it will feel more occlusive and a little more waxy.
So let's put this all together to make a drier feeling lotion. First, as per Frank's request in this post, we'll look at a basic lotion, then a lotion with some modifications!
BASIC DRY FEELING LOTION

2% to 3% humectant (sodium lactate will feel drier than glycerin, but you can use that here, too)
OIL PHASE
5% BTMS
3% cetyl alcohol
10% oils
5% butter (optional, just increase oils to 15% total)
COOL DOWN PHASE
0.5% to 1% fragrance oil (optional)
0.5% to 1% preservative
For this recipe, make sure you choose the drier feeling oils and butters I mention above.

This should make a medium weight lotion that feels dry, depending upon the thickener you use. As a note, you can take your favourite lotion recipe and substitute the suggestions I've made here rather than trying a new lotion recipe from scratch!
Let's take a look at making a lighter and drier feeling, quickly sink-in-able lotion tomorrow!
