Silicone Safety and the Cosmetic Industry

The use of silicones in personal care products continues to expand because of the unique performance attributes they provide and their well-established record of safety. As a result, progressively larger volumes of silicones are being released to the environment, and interest in their life cycle has increased. The present article summarizes relevant fundamental chemical and physical properties of silicones and how these relate to material performance, safety and environmental fate.

Untouched, 'Primitive' Microbiome Sets the Skin Health Benchmark

As it turns out, on skin, the more "bugs," the better; and cosmetics could be negatively affecting their diversity. New research from the UK compared microbiomes to set a "healthy skin standard," against which the effects of products can be measured, in the future.

Kao Takes the Heat Off Infrared-exposed Skin

By focusing on principle factors related to light wave interference, Kao researchers have identified a means to selectively block the NIR wavelength.

Improving the Sensory Properties of Lye Hair Relaxers

Previous work found soluble silicates in lye relaxers to impart positive effects. Therefore, a compound based on potassium silicate, alkyl polyglycoside and glycerin was developed to improve the effects of lye relaxers on the mechanical and sensorial properties of hair. This article explores various benefits of this compound using variations of two lye relaxer test formulations.

Pigmentation, Swelling and Wrinkling in the Eye Area

How the Skin Microbiome Softens UV Assault

New evidence suggests the skin microbiome may reduce the immuno-suppressive blow of UV on skin.

IFSCC Probes into the Biology of Cosmetics

Parrot feathers, stem cells, melanin, cellulite and epidermal tight junctions were among the many biology-themed papers presented during the 25th IFSCC Congress, held Oct. 6–9, 2008, in Barcelona. This heavy focus on biology is indicative of the evolving actives arena and likely a direct response to the antiaging consumer trend.
