The Safe Cosmetics Act of 2010, (H.R. 5786) passed by the House of Representatives into committee, is starting to look like it is going to be a reality, not in small part due to the lobbying of very large cosmetics concerns who would like the House to stop artisans from competing with them.

Nanofibers – the cotton candy of cool science

DeAnne — Fri, 25 Jun 2010 02:07:36 +0000

You know the big difference between me and nanotech researchers? I have never once been at a carnival with a big ball of spun sugar and thought “Wow, I could make nanofibers with that cotton candy machine!” But that’s just what happened with the bioengineers at the Harvard School of Engineering and Applied Sciences, as [...]

Is there Lye in your Soap?

DeAnne — Tue, 15 Jun 2010 16:36:34 +0000

Contributed by Ruth Esteves at Sirona Springs Handmade Soap. Soapmakers often get asked about the use of lye in their soap. The fact is that lye (sodium hydroxide) is indeed used to make soap. While in many minds, “lye soap” brings up images of grandmas and washboards and red, red hands, anyone who [...]

SciTechStory: Janus dendrimers and dendrimersomes

DeAnne — Tue, 25 May 2010 13:31:56 +0000

One of the groovy things about science is that obscure discoveries can suddenly become world-changing. As an example; examine the organic material called a Janus dendrimer. Janus was the dual-faced Roman god. Dendron is the Greek word for ‘tree’ or many branches. A dendrimer is a molecular sphere with many branches forming the [...]

Nanotech, vaccines and skin absorption

DeAnne — Tue, 27 Apr 2010 13:46:58 +0000

I’ve talked before about how lotions work, and skin absorption rates, and the claims of certain cosmetics manufacturers that they have a product which will “penetrate the skin” and do magical mystical (usually anti-aging) things. But we know, unless a product has been deliberately designed to penetrate multiple skin layers, the skin doesn’t let much [...]

Consumer Reports agrees – “anti-aging” serums useless

DeAnne — Wed, 07 Apr 2010 15:51:16 +0000

For years, I’ve been saying that “anti-aging” serums were junk. I’ve read the white papers, I’ve tested the products, I’ve looked at the results…and I’ve said over and over that those bottles of hope were nothing more than modern snake-oil sold to a culture of women who have been taught to fear aging. I’ve gone [...]

Psychopaths sell copies. Science…not so much, apparently

Colorado legislation may derail small manufacturers

DeAnne — Wed, 24 Feb 2010 15:33:39 +0000

Recently a bill has been proposed in Colorado, the ‘Colorado Safe Personal Care Products Act‘. Hearings on the bill begin in March.

DeAnne — Wed, 20 Jan 2010 17:21:52 +0000

Creme-to-Powder eyeshadow is a relative newcomer to the cosmetics market. It has the lasting power of previous generation’s creme shadows, but without the creasing and goopy feel. It’s a semi-solid shadow that can be applied using your finger or a foam applicator, but best results are achieved by using a brush. When [...]

More natural sanitizer formulas

DeAnne — Wed, 02 Dec 2009 16:28:11 +0000

Earlier I posted a formula for a quickie hand sanitizer, but a couple of folks have mentioned that they’re not too hip on the smell, or they would prefer a “spicier” or “fruity” note rather than a minty note. So, here’s a couple more formulas to keep you safe and sanitized during the cold and [...]

Natural Preservatives

DeAnne — Tue, 15 Sep 2009 15:57:03 +0000

A preservative is essentially a chemical agent that will destroy or inhibit micro-organisms in finished formulations. There is ample scope for microbial contamination at the end user level.
