Weekday Wonderings: Using urea, finding data sheets & formulas, ULProspector, and cutting the ends of tubes for pumps or misters.

Just a few thoughts that didn’t seem to fit into any other posts… Please please please do not use urea in your products if you’re not creating a pH buffer – using something like sodium citrate and citric acid or sodium lactate and lactic acid – because it can cause upward drift of our pH,…...

Weekend Wonderings: Can I combine cationic ingredients with non-ionic or anionic surfactants?

I’m doing my best to respond to your comments, but considering the other day I made it through three comments before spending a morning researching and writing yesterday’s post on cetrimonium chloride, it’s not as simple as writing a few lines and being done if I want to offer you the most information I can…....

Weekday Wonderings: Is MCT the same as PEG-6 caprylic/capric triglycerides? Can I add things to aloe vera gel? Using SCI in liquid products?

I haven’t been answering many comments you’ve been leaving on this new blog because I feel that when I enter a conversation, it stops, and that’s no fun.

Comments, foaming bath butter, and your thoughts on re-using containers

Holy cow! I’m away from the comments sections for a few days – I was teaching a Valentine’s Day class at Voyageur Soap & Candle on Saturday, and writing non-blog related things Sunday while resting my arm a bit and looking after Raymond, who’s fighting off some virus and feeling lousy – and you’ve all…...

Weekend Wonderings: How much preservative to use in an emulsified scrub?

In this post, Using black cocoa butter in emulsified scrubs, Vintage Blue asked: If I’m reading this right the preservative goes into the mix before I add the sugar. So I only calculate the preservative based on the weight of the oil mix not the oil and sugar? Wouldn’t i be short on preservative if…...

Weekend Wonderings: Can we use castille soap in face cleansers? How can I make an oil only product feel less greasy?

Wow, I can’t believe it’s been over a month since I trashed my back! (To be specific, it’s my piriformis, hip flexor, and gluteus medius muscles that started off in spasm, and it’s moving across my back and up into my mid-back. Yep, it’s a big spasm party!) It still hurts to sit up for…...
