The other day, we took a look at a few ingredients that might make our skin feel cooler. (And there’s a neat discussion going on in the August Q&A about ingredients that might make our skin feel warmer.) In the July Q&A, Mary shared, Today it is 110˚F degrees outside and I have to be outside...

Q&A: What ingredients could make us feel cooler? (updated)

In the July Q&A, Mary shared, Today it is 110˚F degrees outside and I have to be outside in this heat. When we were playing with Aristoflex AVC, I made a gel lotion with cucumber hydrosol that I called “cool as cucumber”. It is a perfect lotion for hot flashes! I like to use it around...

Ingredient: Moisture Plex Advanced (humectant)

I can’t believe I haven’t shared my thoughts about this ingredient from Formulator Sample Shop! I’ve used it a lot for years, especially in products where I didn’t want the stickiness of glycerin.  Moisture Plex Advanced from Formulator Sample Shop (INCI Glycerin & Water & Sodium PCA & Urea & Trehalose & Polyquaternium-51 & Sodium Hyaluronate). I’m...

Weekend Wonderings: Difference between carbomer vs. acrylates/C10-30 alkyl acrylate crosspolymer? What conditioner can I use for very fine hair? What’s the difference between dilution and ratio?

Still suffering from this horrible cold, although my throat is feeling better and my skin doesn’t hurt so much. I keep drinking vast quantities of chicken soup and honey & lemon tea and spraying my throat with echinacea while sucking on zinc tablets, and I think it’s all working. I’m sure the rest isn’t hurting...

Glycerin is water soluble!

I addressed this the other day, but I think I need to say it again as I’ve seen a three posts or e-mails in the last two days referring to glycerin as oil soluble. Glycerin is water soluble. It is the very epitome of being water soluble. Let’s take a look at the chemistry –...

Weekend wonderings: Chemical and physical exfoliants together in a facial scrub, using sodium lactate, making shampoo, and hair treatments

In this post, Julie asks:  I was wondering if it would be too abrasive to use a chemical exfoliant together with a physical exfoliant?

In this post, Anonymous asks: Hi Susan, I have a question about glycerin. I have read that it can act as a preservative, but the amounts I’ve read where it’s effective have been anything from 15-70%.

Question: Can we use too many humectants?

In this post, Nedeia asks: I LOVE humectants. I always use glycerin, sodium lactate, panthenol, urea, Na PCA, oats and wheat proteins, I just LOVE them in my products! But I guess I tend to over use them, because sometimes the gels I am using all of them into is sticky. I always use less than...

Honey: Using it in our products

Honey is a good humectant, so it might be a good addition for our products…but I would want to heat and hold it to get rid of any possible spores, and we know that subjecting honey to heat and/or light can break it down, so will it behave as a good humectant while in our...
