I hear that! Decades ago when I was working in an OB/GYN practice, I was getting a ton of patients in with vaginal rash and irritation. The first thing that I ask is if they’ve tried any new products in that area like soap. I was told that they had gotten a sample of a new oil of Olay soap in...

You might want to consider formulating a shower bar instead of a lye based soap. Most soaps of this nature have a pH anywhere from nine on up which is some thing that will strip the acid mantle of the skin and leave your skin vulnerable to inflammation. Shower bars, if they are made well can...

Hence the beginning of this debate, my position being, if you're concerned about skin reactions from EO's, PS80 is an odd choice as it has a history of skin reactions...there are gentler options.

If I remember the original post correctly, there was no ETOH in the formula and although just shaking it would be fine, she was concerned about high concentrations of EOs on her skin during spraying.

There is no argument that SCI isn’t natural, the point is, of the purely synthetic ingredients, how much is there and has it been deemed harmful or beneficial in those amounts. This started off about PS80 (I believe) for a person with known severe skin reactions. PS80 has a well known history...

Ummm...last I looked most if not all plastic is made from petroleum, which as you state is natural

Once you know how to convert percentages into grams, then you can take all your gram recipes and convert them into percentages. That will allow you to make batches of any size. Having all your master recipes in percentages is a big time saver as once you have that...you can re-batch at pretty...

I don’t think the issue with petroleum is whether or not it has a natural origin, my understanding of the issue of petroleum is that it can’t be metabolized, it may be carcinogenic, it’s occlusive and it has no nutrient value for the skin. Just because somethings natural doesn’t mean it’s good...

I like the combo of the dual lye solution. I don’t know if the potassium hydroxide is the reason it works so well, but it’s the nicest base I’ve ever worked with, and it’s really easy

To convert percentages into weight take the percentage divided by 100 and multiply by the amount you want in grams. You could use whatever measurement you choose, it doesn’t have to be grams, it could be ounces… But it had to be consistent throughout. (The ingredient percentage/100) x total...

Soap and clay has a couple of recipes for a whipped soap base that is rocksolid stable… Although the most stable rocksolid can possibly disintegrate depending on the heat. But it is really nice quality and to make and you can use this soap paste for more than just whipped soap. And you can make...

As a former University Professor, teaching is what I do. Unfortunately with the number of people in this post, I couldn't be sure who understood the origin of the term and I wish I had the time to review all old posts, but I don't. I am well aware of the credentials of the membership, I don't...

Did you check the raw ingredient database? Syndet is a nickname it came from "Synthetic Detergent" SCI does not fall in the category of a synthetic is it is not a man made chemical, the raw ingredients are natural, but I understand that most people misuse the term. We will just have to agree...

I agree but again, you are misusing the term "synthetic" a synthetic is a component completely man made, in a lab. SCI is not a synthetic, it is a natural ingredient that has been processed to alter its function. And if you read the ecocert qualification, you see that they are VERY picky as...

I think you may be interpreting the sentence differently than intended. In a nutshell, a synthetic is completely created in the lab, where as certain components may be taken from nature and processed. "Chemical processes" refer to what chemical components are allowed in the processing of these...
