Nanoemulsions vs. Emulsions in the Delivery of Coenzyme Q10 and Tocopheryl Acetate

This article compares the ability of mixed emulsifier nanoemulsions and polysorbate 60 emulsions to deliver coenzyme Q10 and tocopheryl acetate into the skin. In vitro skin penetration data shows that in newborn pig skin, nanoemulsions can deliver higher amounts of both actives than emulsions.

Correlating the Structure and Rheology of Lamellar Liquid Crystalline Phases in Emulsions

This paper describes the correlation between the structure of liquid crystalline phases in emulsions and their rheological characteristics. An oleosome/lipophilic liquid crystalline-forming system and hydrosome/hydrophilic liquid crystalline-forming system were investigated. At the same high shear rate viscosity, the oleosome-system showed less thixotropy and rapid recovery when compared with the hydrosome-system.

Properties of a Pseudoceramide Multi-Lamellar Emulsion In Vitro and In Vivo

Tests of a pseudoceramide multi-lamellar emulsion formulation for its stability and its assistance to barrier recovery in vivo on damaged skin suggest dermatologic and cosmetic possibilities.

Cold Processing of Emulsions

The use and application of emulsions and emulsion science are widespread through the personal care industry. Conventional methods for processing emulsions require significant quantities of energy and time, thus cold process emulsion technologies have gained popularity. These provide the means to reduce both the energy demand and timescale of manufacturing processes, as will be described here.

Properties of Surfactants: Emulsions

The metastable nature of two insoluble materials is critical to understanding the nature and performance of emulsions. This metastability and the requirement that the emulsion be cosmetically appealing offer unique challenges to the formulator.

Consumer Perspective—Skin Types and Sensory Experience

Sophisticated texture and fragrance as part of a formulation’s aesthetics are important to the discerning consumer, and skin type is the primary influence behind how the consumer perceives a skin care product. For example, consumers with dry skin require a richer moisturizer, even though the product should absorb quickly for a smooth finish.

Nonaqueous Emulsions: History and Current Specialized Applications

Since the early 1980s, nonaqueous emulsions have attracted technical interest as potential vehicles and delivery systems for personal care products. This is due to the development of a broad range of silicone-based emulsifiers, silicone polymers and other polymeric emulsifiers that have enabled their use. This article will briefly review their history and evolution into current-day specialized applications.

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.

In reality, fragrance often is the most chemically complicated component of the formulation, and understanding its technical aspects is essential for the creation of an acceptable product.

Fragrance in Emulsion Systems and Surfactant Systems

Fragrance is a complex system of aroma chemicals whose potential to interact with the base in formulated products is reviewed in this article, with a focus on fragrance in emulsion systems and surfactant systems.

By adding water to the concentrate and stirring at room temperature, the emulsion builds up to a final form based on the amount of water added.
