Today I think I'll try formulating a light, moisturizing, anhydrous, anti-itch spray that will reduce his desire to scratch, help heal the current wounds, and moisturize enough to keep further damage from happening. (Remember, I'm not claiming this product will cure anything. I'm hoping the various features of each oil will help soothe something. Although I'm fairly sure the word "soothe" is also not allowed, you get the general idea...)
What's the point of this spray? I want to reduce the itching, heal the current wounds, and moisturize his skin. I would like the oil to be a little occlusive, so I'll need something heavier. Ideally I'd like a humectant, but that's a bit difficult with oils only.
Who will use this spray? My husband (I love that word!) loves my products - whenever I tell him his hair looks or smells great, he always says, "That's thanks to the exclusive hair care products I use!", which is incredibly sweet - and he'll use them. He is also very aware that all products have a "best before" date, and I'll bug him if he's using them beyond that time. He isn't a fan of having his hands covered in stuff after applying a really thick lotion (like sunscreen), and he's a fan of the spray-on type applications.
So I need to make something light that won't make his hands feel all slick for a long time, but will be occlusive enough to keep the moisture on his skin on his skin! He's very aware of the expiry date of any product, so I'm not limited to the oils I will use, but he does like a drier feeling product if he has to apply it himself. And I'll make a spray, because I know he'll use it! (I'd already decided on making a spray when I thought of this product idea, but this is where I'd decide the format of the product - spray, jar, bottle, tottle, and so on.)
There are a number of oils I'm considering for this application...
- Castor oil - great phytosterols, analgesic, penetrates skin well
- Shea butter - great phytsterols and allantoin, occlusive
- Coconut oil - anti-inflammatory and anti-itching, help with weather damaged skin
- Calendula oil - speeds wound healing, dry feeling oil
- Cranberry oil - great phytosterols with a dry feeling
But there are reasons for not using each of them. Castor, shea, and coconut are all too heavy for this application, and I don't have calendula or cranberry oil.
These seem like good oils for this application...
- Sea buckthorn oil - high levels of Vitamin E, high levels of phytosterols, palmitoleic acid heals wounds and scratches and acts as an anti-microbial
- Macadamia nut oil - squalene, palmitoleic acid, high levels of phytosterols, oleic acid to moisturize and regenerate cells with some anti-inflammatory properties, an astringent oil.
- Soy bean oil - linoleic acid to help with barrier repair, high levels of Vitamin E, high levels of phytosterols.
- Borage oil - high levels of GLA and linoleic acid to help speed skin barrier repair, an astringent oil.
- Evening primrose oil - high levels of GLA and linoleic acid to help speed skin barrier repair, an astringent oil.
- Pomegranate oil - high levels of punicic acid that is anti-inflammatory, gallic acid is a wound and burn healer, very high levels of phytosterols, an astringent oil.
- Olive oil - a humectant, it has some nice phytosterols that will help with inflammation and itching.
I'll start with the macadamia nut and soybean oils as the basis for this oil. I think 30% macadamia nut and 25% soybean oil will give a nice mix of greasy and dry oils. Sea buckthorn oil works well at 10%, and I'll use the evening primrose at 20% (the suggested amount). I'll use the pomegranate oil at 10% (suggested use). As much as I'd like to include olive oil, it's a little heavy and greasy for this application.
I'll add some IPM to this mix as a penetration enhancer and to impart a less greasy feel (although with all these non-greasy oils, this might be overkill), and dimethicone as an occlusive and barrier ingredient (I'll use the 350 cs version so it is more watery). I'm not adding a fragrance because I don't know what will irritate his skin, and I'll throw in 1% Vitamin E as an anti-oxidant and moisturizing ingredient. This should have a shelf life of 6 months - thanks to the evening primrose - and I'll only make a small batch at a time so it won't go rancid on us!
Okay, so I have my oils chosen - let's formulate!
30% macadamia nut oil
25% soy bean oil
10% sea buckthorn oil
10% pomegranate oil
20% evening primrose oil
1% Vitamin E
Mix the oils together. Bottle in a spray bottle.
