Specialized surfactant systems that form multilamellar vesicles can be used to design high performance shampoos that outperform micellar formulas. These materials combine with and stabilize actives ranging from molecular to particulate, liquid to solid, and hydrophobic or cationic, to deliver them equally to damaged and virgin regions of hair to act where they are needed most.

The distribution of a conditioning shampoo’s cationic polymers and silicone oils along the hair fiber defines its performance. Therefore in the present paper, researchers conduct spectroscopy and microscopy measurements to assess the polymer and silicone deposition of various conditioning systems on hair fibers, the results of which are used to compare efficacy.

Claims for hair products generally are not associated with clear cut outcomes. Therefore, consumers have no standard by which to compare product efficacy. In relation, the North American Hair Research Society (NAHRS) has proposed standards for hair product claims, outlined here, which relate to characteristics including frizz, color fastness and curl retention, among others.

The authors describe how the use of amphiphilic silicones or surfactant silicones has allowed formulators to efficiently incorporate silicone polymers into personal care products. These materials act by lowering the surface tension in the oil phase of a formulation, allowing for easier spreading on skin and hair.

Vegetable oil-based esters are shown by the authors to improve the tactile attributes of vegetable oil by lowering its viscosity and improving its spreadability, in addition to providing environmentally friendly options for cosmetic chemists.

Here, a micro-wax dispersion is shown to provide conditioning and anti-hair breakage properties. The authors incorporated the material into test shampoos, compared them with two silicone-based benchmarks, and found the micro-wax shampoos provided comparable conditioning and improved hair breakage prevention performance. Results were confirmed in a hair washing test.

A new broad-spectrum UV filter to protect hair from color fading and integrity damage, quaternium-95 (and) propanediol, has been developed for rinse-off formulations. Shampoos and conditioners containing this material protected dyed hair against surface tryptophan degradation and tensile strength reduction.

In the present article, a renewable ingredient microemulsion is formulated that is free from ethoxylates and sulfate groups. Used as an additive, the material boosts the conditioning performance of shampoos and improves wet-combing performance by affecting phase separation. In addition, base formulas for standard and “green” shampoos are discussed.

Complexity theory is used here to explain the formation and properties of polyelectrolyte complexes, whereby organized structures built through self-association exhibit synergistic properties. These materials can create new compounds and offer new benefits, as shown by the present work in which a complex based on PVM/MA copolymer and polyquaternium-28 is used to treat damaged hair.

Formulations containing quaternary-modified olefin-graft polymers are shown here to improve the permanency of artificial hair colorant in human hair exposed to repeated washing. In addition, when these polymers were applied to hair by a sulfate-based shampoo, the foam height and viscosity of the shampoo remained unaffected.
