Nonwoven Nanofiber to Incorporate Additives

Using proprietary technology, various types of particles or additives can be either entrapped in the nanofiber matrix or encapsulated within the nanofibers.

Nanotechnology and Skin Delivery: Infinitely Small or Infinite Possibilities?

Nanoparticles have been defined as single particles with a diameter less than 100 nm,4 which includes titanium dioxide in transparent, inorganic sun care products, and is usually extended to 200 nm to include the zinc oxide in those products. But nanoparticles are only a subset of nanomaterials, which can also include cyclodextrins and liposomes.

The Four Rs of Skin Delivery

This review aims to explain the implications of nanotechnology in cosmetic science and products, to eliminate the "unknown" aspect.

Skin Penetration of Liposomes

There is a second category of nanoparticles that is specifically designed to penetrate skin: liposomes.

Skin Penetration by Quantum Dots

Quantum dots are nanocrystals that are used for imaging purposes in medical diagnostics (and not in cosmetics). They have a metallic core surrounded by an inorganic shell coating.

Researchers Nano-size Calcium Phosphate for Drug Delivery

Researchers at Pennsylvania State University have proven that nano-sized calcium phosphate delivers drugs safely and effectively to skin.

Characterization of Multilamellar Vesicles for Cleansing Applications

In the present article, the authors characterize a multilamellar vesicle (MLV) system used in personal care and verify its structure via X-ray scattering, rheology and fluorescence microscopy. This enabled the study of MLV formation to investigate bulk rheology characteristics. The results are presented here as application-relevant properties.

Microneedles: Just Deep Enough

Microneedle technology could, with supporting research, serve as a novel delivery system for personal care applications. Additionally, ingredients previously labeled as ineffective may find new life via this method, increasing the opportunity for skin care R&D.

A Delivery System for Treatment Bar Soaps

Many desired additives are not compatible with soap due to either the chemistry or the manufacturing process. Here, the authors describe an encapsulated delivery system incorporating polymers that survives the extrusion process and adheres to skin.

Customizable Spheres for Cosmetic Application

Umang Pharmatech Pvt., Ltd has launched small beads for cosmetic applications.

Delivering On Time, In Full and On Target: Part II

This second installment continues a discussion from Cosmetics & Toiletries magazine’s May 2008 issue and is also based on a chapter written for the book Skin Barrier: Chemistry of Skin Delivery Systems. Practical information for the cosmetic formulator regarding optimization of skin delivery has been added.

Encapsulation Technology for Skin and Hair

Salvona Technologies has launched a technology platform that can be used to encapsulate a wide range of functional ingredients.
