Copolymer to Improve Pigment Dispersion in Lipsticks

Lipstick is formulated with pigments for the obvious reason of color, but formulators always face the same technical difficulties of pigment dispersion and final shade matching. The present article explores solving these two lipstick dilemmas with an amphiphilic copolymer to improve pigment dispersion and texture of lipsticks.

The Best Sunscreen? The One People Will Use.

This guest advisor commentary comes from regular Cosmetics & Toiletries contributor and photochemistry expert Craig Bonda, president of Inception Partners, LLC, and technical consultant to the sunscreen industry.

The Effect of Skin Metabolism on the Absorption of Chemicals

Skin expresses enzymes that can metabolize endogenous molecules but little is known regarding how they impact the delivery of xenobiotics. This review of recent works shows that skin metabolism alters the dermal absorption of lipophilic compounds, which opens new areas of investigation regarding the safety and efficacy of topically applied cosmetics.

Patent Picks—Lipstick Gloss, Probiotics, Anti-acne, Cosmetic Films, Heat Shock Proteins and More for Skin

Patent Picks are compiled by the editors from publicly available sources. This edition features inventions related to cosmetics and skin care, including heat to improve lipstick gloss and probiotics for oily skin, as well as heat shock proteins, FABACs, improved vitamin C derivatives, an anti-acne blend, a skin-smoothing cosmetic film and a photo-initiated filler from the medical field.

Part II: The Clinical Effects of a Natural Dipeptide on the Biological Cascade

The peptide N-Acetyl-Tyr-Arg-Hexadecylester (NATAH), found in Part I to stimulate the production of elastic fibers in vitro, was next tested in vivo for its capacity to improve skin elasticity parameters, using various biophysical and imaging techniques. Significant differences in facial ptosis and extensibility were observed in the 56-day, vehicle-controlled clinical study described here.

The Effect of Glycerol on the Water-holding Capacity of Chemically Irritated Skin*

Glycerol is one humectant commonly employed due to its high hygroscopic and hyperosmotic properties. It is used in cosmetics as a moisturizer and in pharmaceutical formulations as an active compound.2 Being naturally present in the skin, glycerol was quickly identified for its role in skin hydration, similar to natural moisturizing factors (NMF).

Meeting the UVA Challenge: Inorganic-only Sun Protection

The production of a range of titanium dioxide-based dispersions is explored to provide enhanced UVA protection, in comparison with ultrafine titanium dioxide. Formulations containing these dispersions as the only active are shown to achieve a UVA protection factor that is 1/3 of the labeled SPF value, thus meeting European Commission recommendations.

Visualizing the Impact of Emulsifiers on Emulsion Perception

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.

Part I: The In vitro Effects of a Natural Dipeptide on the Biological Cascade

The peptide N-Acetyl-Tyr-Arg-Hexadecylester (NATAH) was found to stimulate the synthesis of tropoelastin in cultured human dermal fibroblasts as well as augment the activity of all important actors in the assembly of elastic fibers, including Fibrillin 1, Fibulin 5, Decorin, LOX and Transglutaminase, among others. This is shown here both in monolayer cell cultures and in a 3D skin model.
