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.

Moraceae Emulsion Exhibits Stability, Antioxidant and Antibacterial Activities
A recent study describes the development of a topical emulsion containing the leaf extract of
Morus nigra L.
and tests for stability as well as antioxidant and antibacterial activities of the formulations.

Nature-derived Care for Sensitive and Difficult-to-treat Skin Types
A number of consumers can be classified as having difficult-to-treat skin types, being both dry and oily and prone to periodical inflammation in specific areas. New active ingredients derived from nature provide gentle yet efficacious solutions to address these needs. These skin types and solutions are addressed herein.

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.

Hydrophobically Modified Inulin: A Novel Polymeric Surfactant and Emulsion Stabilizer
After a short introduction illustrating the basic principles for steric stabilization by polymeric surfactants, the authors describe a novel polymeric surfactant that consists of hydrophobically modified inulin and demonstrate that it is an effective stabilizer for O/W emulsions, suspensions, nano-emulsions and multiple emulsions.

Liquid Crystals in O/W Emulsions with Urea: Development and Testing
Using a ternary phase diagram, the authors developed systems based on nonionic surfactants, light paraffin oil, water, and (optionally) urea. Systems in which lamellar liquid crystals formed and in which urea was an ingredient showed higher occlusive power and lower TEWL in in vitro tests.

Dove and P&G Experts on the Hair Bonding Buzz—Plus 3 Main Types
The hair bond builder or "multiplier" market is expected to expand at a CAGR of 7.80% from 2021 to 2028. Here, Dove and P&G experts help us explain why and explore the three main types of bonding agents.
Rheology/Thickener
Bring Food to the Soul of your O/W Emulsion with a Dual Rheology Stabilizing System
Cosmetic emulsions can be stabilized via bulk rheology and interfacial rheology by using a unique synergistic blend of two polysaccharides in a technology derived from the food industry.
Literature/Data
Study Finds Sustainable Thermoresponsive Whey Protein- and Chitosan-based O/W Emulsion Possibilities
In this study, the biopolymers whey protein and chitosan were used to create a thermoresponsive emulsion. The impact on rheological properties with chitosan and specific oils, as well as response to temperature, were investigated.

Pop the Cork:
Quercus suber
for Naturally Sourced Antioxidants and Emulsion Stability
Consumers demand better and more sustainable alternatives. Further, some bioactive ingredients register greater biocompatibility. This has driven the industry to search for plant-derived compounds with biological activity.
Quercus suber
L., or cork oak, is shown here to provide an interesting option.

A Surfactant/Biopolymer Stabilizer for Emulsions
An emulsifier/biopolymer system using a mixture of nonionic surfactants and two biopolymers was developed. The surfactants provide effective steric stabilization against coalescence, whereas the biopolymers provide a high residual viscosity and yield value, thus providing stability against creaming. The mechanism of stabilization is discussed in terms of the synergy between the two biopolymers.
