Differing amounts of Fischer-Tropsch (FT) wax were used in petroleum jelly and final cosmetic emulsions to evaluate moisturizing effects in skin. FT wax was shown to perform as well or better than traditional mineral-derived products.

This article reviews and assesses damage types caused to hair before and after artificial coloration, i.e., by bleaching, perming, heat treatment, UV exposure and shampooing, to compare how they impact color durability individually and combined. Formulation emerges as the key to designing shampoos that efficiently deliver actives to improve color protection against these and other damage types.
Comparison of Age Determination by Three Evaluation Methods: Self-assessment, Expert Grader and Naïve Grader

This exploratory study investigates how consumers perceive age, using objective and subjective approaches. Results of this study suggest that when a subjective approach is implemented for age determination, subjects affix their emotions to the evaluation. The reverse logic was applicable for the expert and naïve grader methods, as grader results appeared more neutral than the self-assessment.

Although this author cannot deny that moisturization capabilities can provide relief for those who suffer from flaky, itching or irritated and dry skin, it would be careless not to acknowledge the marketing-based beguilement within this moisturization sector.

This work evaluates the impact of temperature on test substrate surfaces during the application, spreading and drying steps of the in vitro method to measure ultraviolet (UV) transmission. The authors work in a range of temperatures, between 20°C to 35°C, and demonstrate that controlling temperature is a key parameter and should be strictly controlled to ensure reliability.

Aging influences cutaneous parameters that give rise to progressive changes in three skin chromophores, altering the visual homogeneity of skin. To address these changes, the authors developed and examined the effects of a complex based on Siegesbeckia orientalis and Rabdosia rubescens using a novel skin imaging technique.

To evaluate the comprehensive effects of shine and color intensity in hair, a hair color vibrance factor has been developed to enable new claims for hair dye formulas and after-dye treatments. Experimental results described here show how varying the ingredients in shine spray and hair dye formulas affect this factor and correlate with subjective panelist assessments.

Here, the author compares two methods to determine the maturity of corneocytes based on their cross-linking that could be used to evaluate the anti-aging effects of molecular agents. The first utilizes microfluorometry, while the second involves F-D curves generated via contact mode AFM. Both methods successfully detected differences in mature or immature corneocytes with 95% confidence.

It should perhaps go without saying that consumer products are sold using consumer language. Market researchers and consumer scientists spend a great deal of time studying their target audience and learning this vocabulary, which subsequently allows the recounting of product benefits in the same terminology.

In the present work, the antioxidant capacities of three essential oils derived from basil and thyme were evaluated using a photochemiluminescence (PCL)-based assay. In addition, since the base formulation can affect the antioxidant activity of oils contained therein, ingredient interactions within final formulations were investigated.

In the present article, the authors assess the skin irritation and sensitization potential of 1,3-propanediol (INCI: Propanediol). Results in animals and humans by acute or repeat exposure support a low potential of skin reactivity for the material. In addition, the skin reactivity potential in humans was found to be lower with 1,3-propanediol than 1,2-propanediol (INCI: Propylene Glycol).

While previous algorithms for predicting the skin absorption of permeants was based on in vitro data, the present article proposes a quantitative structure-activity relationship (QSAR) model based on in vivo human data. Here, a set of human in vivo data is described that provides entry into predicting the penetration of cosmetic ingredients.
