Assessing the Impact of Hair Damage Types on Color Retention
This article reviews and assesses damage types caused to hair before and after artificial coloration, i.e., by bleaching, perming, heat treatment, UV exposure and shampooing, to compare how they impact color durability individually and combined. Formulation emerges as the key to designing shampoos that efficiently deliver actives to improve color protection against these and other damage types.

The Perplexing Topic of Hair 'Type': How Do We Classify Hair?
Most hair-related properties and issues can be rationalized by fiber size and shape, and/or the consequences of extreme conditions. However, the varying reactivity of different hair types with chemical treatments suggests potential differences in structure.

Comparatively Speaking: O/W, W/O, Micro, Pickering and Suspo Emulsions
In this installment of his "Comparatively Speaking" series, industry expert Tony O'Lenick compares emulsion types for the benefit of novice formulators.

PIT Versus PIF for the Rational Formulation of Emulsions
This article deliberately pushes the boundaries for cosmetics scientists, showing how the much-used phase inversion temperature (PIT) technique is a limiting special case of a more versatile, rational approach to surfactant optimization: HLD-NAC. This simple way of understanding the basic interactions within emulsion formulations can be generalized to create totally new ways of formulating stable emulsions.

Silicone Amino Elastomer Emulsion for Conditioning and Styling Performance
A nonionic emulsion based on silicone amino elastomer technology enhances hair conditioning and styling, as demonstrated in tests of combing force, curl retention, sensory characteristics, thermal protection and frizz control.
Method/Process
Zeta Potential and Particle Size to Predict Emulsion Stability
Emulsions are popular vehicles in skin care due to their affinity for the skin; however, they are thermodynamically unstable systems. This study investigates zeta potential and particle size distribution as potential screening tools to predict instabilities in emulsion-based cosmetic products, to supplement regular accelerated stability testing.

Comparatively Speaking: Emulsion vs. Colloid
Industry expert Anthony O'Lenick, Jr., explains the different between an emulsion and a colloid.
Actives
Designing Emulsions for Relaxer Actives
Relaxer emulsions have unique requirements regarding pH, hydrophilic-lipophilic balance and minimizing irritation potential. This article suggests ways to meet these requirements and provide an ideal emulsion base for relaxer actives.

O/W Emulsions for Ethnic Hair Care
In the past, many ethnic hair care formulations relied heavily on the use of invert emulsions. These products utilized oils as the primary conditioning agent and were lacking in many respects; they did not provide substantial styling benefits, they tended to weigh hair down, and the aesthetic properties were often greasy and unappealing.

Naturally Inhibit Fragrance Degradation: Rice Bran Sterols in Emulsions
The use of phytosterols is proposed here to retard the deterioration of cosmetic emulsions caused by perfume degradation. For the described tests, phytosterols from crude rice bran oil, a natural and economic choice, were used. A simple and easily controlled technique is described through which the phytosterols provided the desired results.

Clean and Green: A Review of Modern Day Surfactants and Emulsifiers
Many certified organic shampoos and body washes use soaps such as potassium cocoate as their primary cleansing agent, partially due to a lack of suitable, organically approved foaming alternatives. This article reviews the use of modern surfactants and emulsifiers developed based on a green and eco-conscious philosophy.
