Q&A: Creating liquid volumizing shampoo? Part three – surfactant blends

I’m having great fun formulating all kinds of shampoos suitable for fine hair or other types that don’t want to be weighed down. We started last week by looking at different types of shampoos and coming up with base formulas for clarifying, conditioning, and hydrating shampoos. Then we took a look at using different surfactants…...

Q&A: Incorporating SCI into a liquid shampoo or body wash?

In yesterday’s post, we reviewed how we might use sodium cocoyl isethionate (SCI) in a liquid product. We found was poorly soluble in water – 0.01% at 25˚C – so we took a look at a few ways we might incorporate SCI into a daily shampoo. Let’s take a look at a few different formulas…...

Q&A: Using glycol distearate to thicken the daily use shampoo? Using SCI in liquid products? Increasing the solubility of SCI?

In the September Q&A post, Melanie asked, I am trying to make a shampoo using glycol distearate and am having no luck. I do as you suggest, and melt this separately but when I add it to the other ingredients the final product ends up gritty. I have tried adding it all at once, and have…...

Q&A: If anyone has tried salicylic acid in a shampoo how much did you use and do you think it made your product better?

In the August Q&A, Allison asked: I’ve noticed that salicylic acid is an ingredient in some anti-dandruff shampoos (I’m guessing because it helps with flakiness) but it’s also used in a color-protection shampoo that I like. I’m wondering if you know what benefit it might have in hair care other than as a dandruff treatment? I’d…...

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…....

Subscribers’ exclusive: Potential duplication for Perfectly Gentle shampoo from The Honest Company (part one)

Creating a shampoo bar from scratch: Humectants, proteins, emollients, and vitamins

So far in this series, we looked at a duplication for Lush’s Jumping Juniper bar; met the sodium coco sulfate (SCS), a powdered surfactant we could use in such a product; reviewed some other powdered surfactants; then reviewed the liquid surfactants.

Yesterday, we started creating this shampoo bar formula from scratch by looking at the powdered surfactants. Today, we’ll look at the liquid surfactants you can use in this formula.

Creating a shampoo bar from scratch: Let’s meet the powdered surfactants

Yesterday, we met a new powdered surfactant – sodium coco sulfate or SCS – and used it in a potential duplication for Lush’s Jumping Juniper shampoo bar. In both posts, I mentioned repeatedly that we need to reduce the pH to be more acidic as alkaline products – those over pH 8 – are just…...
