Using BTMS-50 (and only BTMS-50, not BTMS-25) as your emulsifier will give the lotion a drier feeling, so you'll want to choose your oils well. If you like a drier feeling lotion, then go for the drier oils like avocado, hazelnut, and so on, and add a little IPM to make it feel drier still. If you like a greasier lotion, then choose the greasier oils like olive, rice bran, sesame, sunflower, soy bean, and so on.
LIGHT SPRAYABLE CATIONIC LOTION
HEATED WATER PHASE
10% aloe vera juice or other hydrosol
3% glycerin or humectant of choice
2% hydrolyzed protein (I like cromoist)
HEATED OIL PHASE
3% oil of choice
COOL DOWN PHASE
1% Vitamin E
1% fragrance oil
0.5% germall plus
Note: Do not use sodium PCA or sodium lactate at 3% in the recipe as they could make you sun sensitive. Instead combine them at 2.5% or lower with another humectant like glycerin or honeyquat. Or just use them at 2.5% and up your water by 0.5%
Follow the general lotion making instructions found in this post. This will produce a light, sprayable lotion you can use with a mister bottle. Feel free to modify this recipe with other hydrosols, extracts, and other water soluble goodies like panthenol or other humectants. If you want to increase your oils, you'll have to increase the emulsifier.
