Study Reveals Pathogen Resistance is Sexy
I love the the smell of a man who doesn't stink; who takes time to wash and apply deodorant. Apparently I'm not alone. In fact, according to a new study, pathogen-prevalent regions see increases in consumer grooming time to give an air of pathogen-resistance and attract mates.

Smell That? Neither Do Beiersdorf Researchers
Beiersdorf researchers have developed a deodorant based on polyquaternium-16 that decreased the production of axillary bacteria, in turn reducing malodor. So no, there's nothing to smell here (but innovation).

Tools of the Trade for Sensory Testing
One challenge in manufacturing is the variance in quality of raw materials; another is the mixing process. Mechanical tests, described here in brief, will quickly identify cosmetics and lotions that should be rejected or reworked.

Patent Pick: Space-filling 'Magic' Cosmetics
A refractive index is this nifty little way to describe how light passes through a medium. It's also the basis for a new Avon invention, which applies optical illusion to impart cosmetic benefits. So, it's magic.

Patent Pick: Sensory Effects as Easy as Pudding
The "wow" factor in product effects isn't exactly as easy as pie. It's as easy as pudding—at least, that what the inventors on this Shiseido patent application believe.

'Zapping' Sensitive Skin: Capsaicin Tests Show
Embelia concinna
Comforts Irritation
In previous work, a flavonoid-titrated active ingredient based on
Embelia concinna
was shown in vitro to calm and soothe sensory neurons stimulated with capsaicin. Here, those results are confirmed in vivo using a capsaicin stinging test with human volunteers.

Modifying Hair’s Structure From the Inside
Changing hair properties is a regular function of daily-use treatments. But what other methods can be used? Altering the hair’s internal structure may be the next way to achieve these changes.

Coiffed Conundrum: Equating the Measurement of Hair Shine
Shine constitutes the ability for light to reflect off of surfaces. For consumers, perceived shine is indicative of healthy hair. For marketers, it is the gateway to hair product benefits claims. But how can shine be measured to support those claims?

Ranking Body Creams by Sensory Properties
Ranking descriptive analysis (RDA) is a sensory test from the foods industry. Here, it is applied to evaluate the properties of four body creams, and the results are compared with those of the well-known quantitative descriptive analysis (QDA) profiling. Findings suggest this technique could positively impact sensory testing for product development.

Balancing Sensory Effects with Improved Scalp Moisture
An oil-based moisturizing ingredient was developed to increase scalp hydration and improve TEWL, while also imparting desired sensory effects to hair. Instrumental and panel tests were performed, described here, which confirmed the ingredient delivered scalp hydration as well as wet hair detangling and softness to hair.

Yield Stress Measurements for Personal Care Part II: Methods
The previous article defined yield stress and explained how to calculate the amount needed for a given application. Here, methods for measuring yield stress are compared by determining the values of two materials: a non-thixotropic acrylates copolymer solution, and a thixotropic body wash. The results provide recommendations for methods in terms of relevance, exactness and robustness.

Applied Neuroscience to Understand Cosmetic Consumers: Consumer Study (part II)
By measuring the non-conscious consumer response to products, concepts and before/after results, it is possible to make decisions for product development and marketing, as well as develop product claims. These possibilities are discussed in this three-part series, as are two case studies.
