Skin penetration of caffeine from commercial eye creams and eye creams designed and optimized based on Hansen solubility parameters.

Computer-aided formulation design can streamline and speed up product development. In this study, ingredient screening and optimizing software, Formulating for Efficacy® (FFE), was used to design and optimize creams for the topical delivery of caffeine. FFE was set up to optimize lipophilic active ingredients, therefore, this study challenged the program's capabilities.

Microwave-Assisted Functionalization of Multi-Walled Carbon Nanotubes for Biosensor and Drug Delivery Applications.

Microwave-assisted synthetic methods have emerged as a popular technique for surface modification and the functionalization of multi-walled carbon nanotubes (MWCNTs) for diverse drug delivery applications. Microwave-induced functionalization of MWCNTs provides a high functionalization and requires less time than conventional techniques. Microwave methods are simple, fast, and effective for the covalent and noncovalent conjugation of MWCNTs with various biomolecules and polymers.

Antiproliferative Efficacy of -(3-chloro-4-fluorophenyl)-6,7-dimethoxyquinazolin-4-amine, DW-8, in Colon Cancer Cells Is Mediated by Intrinsic Apoptosis.

A novel series of 4-anilinoquinazoline analogues, , were evaluated for anticancer efficacy in human breast cancer (BT-20) and human colorectal cancer (CRC) cell lines (HCT116, HT29, and SW620). The compound, , had the highest anticancer efficacy and selectivity in the colorectal cancer cell lines, HCT116, HT29, and SW620, with IC values of 8.50 ± 2.

Transdermal Delivery of Chemotherapeutics: Strategies, Requirements, and Opportunities.

Chemotherapeutic drugs are primarily administered to cancer patients via oral or parenteral routes. The use of transdermal drug delivery could potentially be a better alternative to decrease the dose frequency and severity of adverse or toxic effects associated with oral or parenteral administration of chemotherapeutic drugs. The transdermal delivery of drugs has shown to be advantageous for the treatment of highly localized tumors in certain types of breast and skin cancers.

Blue light protection, part II-Ingredients and performance testing methods.

Background: There are numerous cosmetic ingredients that have been identified to have blue light protection benefits. The urge to learn more about blue light protection claims has led to several substantiation test methods that can be utilized by companies to prove product efficacy.

Aims: Part II of this article provides up-to-date information on cosmetic ingredients that can provide protection from blue light, and methods companies can use to substantiate blue light protection claims.

Blue Light Protection, Part I-Effects of blue light on the skin.

Background: Blue light is emitted visible light between the wavelengths of 400 to 500 nm. The main source of blue light is sunlight, but digital screens, light-emitting diodes (LEDs), and fluorescent lighting serve as additional sources. Concerns about the negative effects of blue light on the skin have rapidly increased over the past 15 years, and consequently, the urge to learn more about this topic is increasing as well.
