As far as the public is concerned, hypothetical risks are real. And if anyone studies a chemical in depth, they can find some effect but whether it should be removed from the market comes down to a risk-benefit analysis. Cosmetic formulation is a continuous process of keeping in step with research, and when a true risk emerges, addressing it.
In humans, the ZAG protein is a modulator of fat mobilization. The present paper identifies an unroasted shea butter extract, enriched in viminalol esters, as a stimulator of ZAG expression and secretion by keratinocytes in vitro. Further, a complex containing the extract is shown to significantly improve the appearance of cellulite within 28 days of application in a clinical setting.
A novel safe hydrotrope and wetting agent with exceptional skin feel is evaluated here for its solvent power and versatility in cosmetic formulas. Key features examined are sensory properties, hair feel modification and improvement of foam performance in skin cleansers.
The present article discusses facial powder containing specific layered color-travel pigments that give a color-flop effect due to light reflectance at different angles. In particular, layering a bluish silver pigment with a sienna pigment is shown to highlight the forehead, cheek and nasal bridge while shading the jaw, chin and alar base of the nose, consequently imparting a slim-looking appearance.
In the mechanical testing world, the tendency for materials to fail under a repeated stimulus is termed fatigue testing, and this article discusses this topic in relation to hair breakage. It will be shown that this alternative testing approach provides considerable insight into the cause of hair breakage, and subsequently allows for the identification of strategies for its minimization; it will also be demonstrated how learning this provides the underlying theory by which anti-breakage and even “strengthening” claims are crafted.
This paper describes an approach to systematically investigate the intrinsic effects of emulsifiers, quantify them and translate them into consumer preferences. These are processed mathematically and displayed in a simplified, two-dimensional map to assist formulation work.
To optimally treat acne, an accurate severity assessment is required1 and while visual assessments have relied on text descriptions, lesion counting and photographic methods, an ideal grading system would be more accurate and reproducible. Further, its ease of use, and time and monetary costs are also important. Here, the authors consider different approaches for improved acne assessments using photography.
Cosmetics in Brunei are regulated by the country’s “Medicines (Cosmetic Products) Regulations 2007,” which are in line with the ASEAN Cosmetic Directive (ACD) and require all importers/ manufacturers to notify the Ministry of Health (MoH) before launching any cosmetic product in the local market.
As I write this, I have just made a bold appearance in Rio de Janeiro; and no, this has nothing to do with topless beaches. At the 2013 IFSCC Conference, colleagues were surprised by my feisty new auburn hair color, formerly a light blonde. In fact, some did not recognize me. My bold appearance even made its way into a media demonstration at the L’Oréal Research Center, although to show hair damage, but still. . . Cosmetics & Toiletries' latest collection of articles is also all about appearances.
