The first thing I ask myself when I’m formulating a product is what exactly do I want to make? What type of lotion, cream, or butter do I want right now, for what body part, and for what reason? In short, what’s my goal for this product? Asking yourself this question is the first step … Read moreLearning to formulate: What kind of lotion do you want to make?
In this post, Patrick asks: I’ve made a hand lotion that our household really likes with Jojoba, FCO, RBO, Soy, Avocado, Shea Butter & Mango Butter. I toss in some fancy additives including panthenol and everything totaled comes to about $5USD for 500g. Not horrible, but a bit much. Anyway, here’s my question: What’s the absolute cheapest … Read moreQuestion: What is the cheapest lotion you could make?
I’ve been doing a lot of thinking about what posts to write next, and I think I’m going to do a series on learning to formulate our products from scratch. Although these posts will mostly relate to lotion making, you can take what I’m posting here and use it for other products. If you are … Read moreLearning to formulate series…
I know most people, if asked, will say they prefer a drier feeling lotion, but a lot of those perceptions are based upon commercial products that contain mostly mineral oil. Most of our vegetable oils feel less greasy than mineral oil, and all of our esters definitely feel that way. So here are a few … Read moreSome thoughts about greasiness in lotions…
As I mentioned the other day, the thickening posts and Iron Chemist will be delayed a few days until the weather warms up enough for me to enter my workshop! I’m willing to suffer for my beloved chemistry, but not so much that the headaches return and keep me in bed for days! I thought … Read moreLet’s take another look at mineral oil!
I’ve written about xanthan gum before, but I thought I’d go a little more in depth in this post! Xanthan gum is an anionic polymer derived from the bacterium Xanthomonas campestris, which can be found on cruciferous veggies like cabbage, cauliflower, and broccoli (all of my least favourites!). In the manufacturing of this ingredient, they … Read moreThickeners: Xanthan gum
It is so cold in my workshop that I can’t go into it, so the posts I was hoping to write about using the thickeners and the Iron Chemist results may be delayed! It’s been below freezing since Saturday, -3˚C or lower in the mornings, and not much higher in the afternoons, and the moment … Read moreWarning: Your regularly scheduled posts may be delayed…
Hydroxypropyl methyl cellulose (also known as hypromellose or HPMC as I’ll be typing from now on!) is a non-ionic, water soluble polymer derived from cellulose. It comes as a white or off-white odourless powder that we use to thicken our products. Because it’s non-ionic, it has many uses like shampoos, lotions, shaving gels, and pretty … Read moreThickeners: Hydroxypropyl methyl cellulose (HPMC)
In this post, Heidi asks…My question is this.They tell us we don’t need preservatives in soaps. Do you believe this is true? And if it is, why do we need a preservative in a solid shampoo bar (syndet)?And how about something without water like a body lotion bar? Great question! Let’s take a look at … Read moreDo we need preservatives in soap?
Don’t confuse guar gum with cationic guar gum – regular guar gum is non-ionic and does not offer any substantivity to your hair, and it’s a fine white powder, not a yellowy powder. It will, however, behave as a good thickener for our products. It’s water soluble and non-ionic, which means you can add it … Read moreThickeners: Guar gum
