    Mineral Makeup for Women of Color

    06/22/06 UPDATE. After posting this, I received an email from a woman who had followed our link to Ada Cosmetics in order to make a purchase. Her experience was frustrating and she asked me to advise potential customers of that fact. While her money was refunded on a lost or never sent shipment, the process of communicating with the company was not to her satisfaction and she felt it was...

    Color Trouble Shoot #2: How to Adjust Colors

    Adjusting a product's color as a last step in processing is not uncommon at all -- people in industry do it all the time. It's kind of the nature of the business.

    The first step is to first figure out in what way a the color of your product is off. The big guys use computers and sensors for this and have very precise ways of measuring hue. We have to depend on our eyeballs and a good sense of...

    Color Trouble Shoot #1: How to Test for Color Variations

    As suppliers of raw materials, we try to make sure that our products are consistent batch to batch. But that doesn't mean that we always succeed. Once we received 100 pounds of a brown oxide which was definitely more red than the "old brown". Another time, we received a titanium dioxide white which was heavier than the "old white".

    The result in both cases was frustration for our customers who...

    Labeling your Mineral Makeup

    Recently, a customer asked me this question:

    I am creating a line of "multi purpose mineral cosmetics" with micas.
    Let's say one of the colored micas contains mica, titanium dioxide, iron oxides, and ferric ferrocyanide. Does the ferric ferrocyanide have to be listed on the ingredients list?? Is that considered something that would be a "trace" ingredient, and therefore I'm not required to list it??...

    About MSDS Sheets

    MSDS stands for "Material Safety Data Sheet". People often think that a MSDS sheet is an ingredients list. While it does disclose ingredients, this is not its purpose. Its purpose is to be an instruction sheet on how to safely handle the product.

    The MSDS gives information such as "What do I do if I accidentally eat it, or get it into my eyes, or inhale it?" Or, "What do I do if I accidentally...

    Safe Cosmetics: a new law, a great organization, and a database to look at. If you are a cosmetics formulator, read this post!

    In October, 2005, Gov. Schwarzenegger signed a law that requires any company selling a personal care product in California that contains any ingredient that's a human carcinogen or reproductive toxin to disclose that to the Department of Health Services starting in 2007.

    Personal care formulators don't like the law, because they feel it misleads consumers into thinking safe products are unsafe. For...

    How Lori Polette took her studies of ancient Mayan paint and turned it into a business that's good for all of us.



    http://www.mayanpigments.com/

    Mayan Blue is a 2000-year-old, lustrous turquoise blue that can be seen in ancient Mayan ruins, even to this day. Until relatively recently, no one knew how they made such a vivid paint so resistant to weather, extremes of pH, chemical solvents and biodegradation.

    Research conducted largely by PhD student Lori Polette revealed why the mix of organic dye from the indigo...
