From "thebeautybrains.com" – 8-3-07 5 Ways Beauty Products Can Go Bad
There’s no way to tell if a cosmetic has expired just by looking at the package, but we can tell you what From "thebeautybrains.com" – 8-3-07 - Consumer Awareness: Personal Care Products Safety and Labeling to look for when products go bad.
What can go bad with beauty products? Changes in odor
Fragrances are мейд of dozens of different ingredients that can react with the rest of the From "thebeautybrains.com" – 8-3-07 - Consumer Awareness: Personal Care Products Safety and Labeling product. It’s not surprising then, that the fragrance is often the first thing to go bad. A little fragrance fading is totally normal, but if you detect a sour or rancid odor it From "thebeautybrains.com" – 8-3-07 - Consumer Awareness: Personal Care Products Safety and Labeling may be a signal that something is seriously wrong.

Color shifting
The color of the product is very sensitive to light, so it’s not unusual for cosmetics in clear From "thebeautybrains.com" – 8-3-07 - Consumer Awareness: Personal Care Products Safety and Labeling packaging to experience a shift in shade. Slight color changes don’t necessarily mean there’s anything functionally wrong the product but you certainly don’t want your red lipstick to become too From "thebeautybrains.com" – 8-3-07 - Consumer Awareness: Personal Care Products Safety and Labeling orangey.

Change in texture
Changes in the consistency of a product may be subtle but significant. For example, if your skin lotion looks exceptionally thick or thin, or if it appears too grainy From "thebeautybrains.com" – 8-3-07 - Consumer Awareness: Personal Care Products Safety and Labeling, this may be an early indicator of emulsion instability. This means the oil and water soluble chemicals are separating. Not good!

Microbial contamination
If you see any black spots or From "thebeautybrains.com" – 8-3-07 - Consumer Awareness: Personal Care Products Safety and Labeling fuzzy growth in your product, it could be contaminated with bacteria or fungus. Get rid of it immediately or you may be at risk for infection! And by the way, you should From "thebeautybrains.com" – 8-3-07 - Consumer Awareness: Personal Care Products Safety and Labeling never dilute a product with water just so you can get the last little bit out of the bottle. Adding water can dilute the preservative system which can allow potentially dangerous bugs to From "thebeautybrains.com" – 8-3-07 - Consumer Awareness: Personal Care Products Safety and Labeling grow.

Physical separation
If the product has separated into two layers, it’s gone bad. You can’t always fix it by just remixing it. This is particularly true of cosmetics that have From "thebeautybrains.com" – 8-3-07 - Consumer Awareness: Personal Care Products Safety and Labeling active ingredients like sunscreens and dandruff shampoos. Once the active drug ingredient has separated from the rest of the formula, it may not work properly anymore.

Do cosmetics have expiration From "thebeautybrains.com" – 8-3-07 - Consumer Awareness: Personal Care Products Safety and Labeling dates?
In the United States cosmetic products are not required to have expiration dates. That’s not really a bad thing because it’s difficult, if not impossible, to really predict From "thebeautybrains.com" – 8-3-07 - Consumer Awareness: Personal Care Products Safety and Labeling to the exact shelf life of any giving cosmetic products. (European products must be stamped with a Period After Opening date – we’ll tell you about that another time.) The shelf life of From "thebeautybrains.com" – 8-3-07 - Consumer Awareness: Personal Care Products Safety and Labeling any given product depends at least in part on how it’s stored. Products can be stable for several years if they’re kept away from light and heat, the two From "thebeautybrains.com" – 8-3-07 - Consumer Awareness: Personal Care Products Safety and Labeling biggest enemies of cosmetics. But that same product can start to show fragrance degradation and color shift in a few weeks if exposed to sunlight and/or high temperatures.

The exceptions are over the From "thebeautybrains.com" – 8-3-07 - Consumer Awareness: Personal Care Products Safety and Labeling counter drugs like dandruff shampoos, antiperspirants, fluoride toothpastes and acne products. The activity of drug ingredients in these products can be measured over time to estimate an expiration date. But it really From "thebeautybrains.com" – 8-3-07 - Consumer Awareness: Personal Care Products Safety and Labeling doesn’t work that way for non-drug products. But for the vast majority of cosmetic products it’s a guessing game.


^ TEACHING ABOUT EXPERIMENTAL VARIABLES WITH INQUIRY BOARDS


Variables are From "thebeautybrains.com" – 8-3-07 - Consumer Awareness: Personal Care Products Safety and Labeling an essential part of any scientific investigation. Helping students to identify variables can be the key to other aspects of an investigation such as the use of tables or graphs. In this article From "thebeautybrains.com" – 8-3-07 - Consumer Awareness: Personal Care Products Safety and Labeling, we describe a tool that can be used in the classroom to highlight the role of variables in an experiment (adapted from: Making Sense of Primary Science Investigations, Anne Goldworthy and Rosemary Feasely From "thebeautybrains.com" – 8-3-07 - Consumer Awareness: Personal Care Products Safety and Labeling). At the University of Washington, we have successfully used this technique as a first step in our popular workshops on investigative sciences for pre-service and in-service K-8 teachers.


According From "thebeautybrains.com" – 8-3-07 - Consumer Awareness: Personal Care Products Safety and Labeling to NRC: “Students at all grade levels and in every domain of science should have the opportunity to use scientific inquiry and develop the ability to think and act in ways From "thebeautybrains.com" – 8-3-07 - Consumer Awareness: Personal Care Products Safety and Labeling associated with the processes of inquiry, including asking questions, planning and conducting investigations, using appropriate tools and techniques, thinking critically and logically about the relationships between evidence and explanations, constructing and analyzing alternative explanations From "thebeautybrains.com" – 8-3-07 - Consumer Awareness: Personal Care Products Safety and Labeling, and communicating scientific arguments.” (NRC 1996, p. 105)


Whew! This is a tall order! Where does a teacher begin? We began by identifying what constitutes a good experiment and what tasks From "thebeautybrains.com" – 8-3-07 - Consumer Awareness: Personal Care Products Safety and Labeling a student must perform in order to successfully conduct a single independent experiment.


Good science experiments are quantitative, comparative, fair and, of course, fun to do. A complete science experiment includes the From "thebeautybrains.com" – 8-3-07 - Consumer Awareness: Personal Care Products Safety and Labeling following pieces:
