Comparatively Speaking: Dye vs. Pigment

Industry expert Tony O'Lenick explains the difference between a dye and a pigment, touching upon solubility and affinity for a substrate.

Three-free: New Generation Nail Polish

It seems the bad press storm surrounding the safety of nail ingredients has passed since most nail polish manufacturers have reformulated to omit these materials. Now, formulators can focus on the horizon for new innovations in nail polish.

Surface Treatment of Cosmetic Pigments

This article describes the chemistry, properties and applications of selected techniques for treating the surfaces of cosmetic pigments and fillers. High-intensity agitation, precipitation, chemical reaction and hydrophilic coatings are discussed.

Oxidative Stability of Botanical Oils in Color Cosmetics

Some cosmetic emollients are particularly susceptible to oxidative degradation when used in the presence of metal oxides. This study examines the results of studies to identify emollients that are less susceptible.

A Light-Diffusing Concept for Antiaging Effects in Makeup Formulations

An innovative light diffusing concept for special optical effect (nylon fibers) makes possible the immediate visualization of the reduction of signs of skin aging while maintaining a natural makeup and youthful appearance.

Pisum Sativum Extract for Safe- and Self-Tanning

The cosmetic industry is challenged to develop active ingredients to provide the skin with a natural, healthy glow without sunlight exposure. Here, the author examines the effects of Pisum sativum extract on melanocytes and shows a time- and dose-dependent increase in skin tone, also suggesting the material could protect skin from UV damage.

Cooking Chemistry and the Formulator: Sugar and Grains

This article is the third in a four-part series that highlights connections between cooking chemistry and personal care product development, including reactions that occur and why, and how to best utilize these reactions, for the benefit of formulators.

Video Imaging in the Measurement of Makeup Efficacy and Performance

Video imaging techniques add quantitative data about the visual effects of makeup when evaluating efficacy and performance of products such as mascaras, lip colorants, facial foundations and nail enamels.

Modified Mica as a Vehicle for Unstable of Irritating Ingredients

A magnesium sodium fluorosilicate mineral matrix is used as a new encapsulating material for protecting ingredients. Examples include uses in moisturizing compact powders, hair coloring powders and mineral sunscreens.

Resins: The Other Kind Of Silicones

Silicone resins trimethylsiloxysilicate and Polymethylsilsesquioxane provide transfer resistance to cosmetic formulations. Phenylcontaining silicone resins additionally provide a high refractive index and gloss. A gelbased silicone resincontaining powder adds improved skin feel and oil absorption.

Color Development Using Silicone Emulsifiers and Dispersants

Several types of PEG/PPG dimethicones and acrylate silicone copolymers were selected, and significant differences in their ability to disperse and stabilize pigments were studied. As the particle size got smaller, the color became deeper and stronger.

Color-Travel Cosmetic Pigments: Interference To The Max

Interference pigments have been used since the early 1970’s to provide iridescent, pearl-like and other effects to color cosmetics. Recent developments have pioneered a new generation of specialeffect pigments for cosmetics.

Makeup Powders Preservation and Water Activity

Spores of Bacillus subtilis and selected molds were used to demonstrate the impact of different thermodynamic water activities on the behavior of microorganisms inoculated in makeup powders with or without preservatives.

Substantiating Claims for a Tanning Magnifier

Tanning magnifiers, known in the United States as tanning accelerators, enhance the substrate or the production of melanin. One example is an innovative N-acyl derivative from L-tyrosine. This article describes a way to evaluate its pigmentation efficacy after UV irradiation. Also discussed is the regulatory status of tanning magnifiers.

In Vivo Quantitative Evaluation of Gloss

A real time polarization analysis technique is described that differentiates components of scattered light in video images and enables in vivo quantitative evaluation of gloss from hair and skin during quality control and claims substantiation.

Meet D&C Black #2: A New, Old Cosmetic Color Additive

The specifications, advantages, disadvantages and handling considerations of carbon black are described, as this old cosmetic color additive – de-listed for 29 years – returns to use with a new name: D&C Black #2

Bright Pearl Complex and Long Radiance Pigment for Enhancing Skin Luminosity

Color fading and dulling of foundation pigments can be avoided by new coating materials and application techniques, as this article demonstrates in the case of a pearl protein extract applied by a fluid air bed coating technology. This technology also treats pigments and fillers to give them optical properties to improve skin radiance.

Thermoplastic Silicone Elastomers Improve Nail Polish Performance

A new thermoplastic silicone elastomer (TPSE) is shown here to improve scratch resistance, chip-off, feel, smoothness, gloss, and color in a nail polish formulation when compared with a formulation without TPSE. The new ingredient proves to be an interesting technology for optimizing nail polishes.
