Physico-chemical challenges on the self-assembly of natural and bio-based ingredients on hair surfaces: towards sustainable haircare formulations

Abstract

Polymers and surfactants are used in many technological and industrial applications such as the manufacture of functional materials and coatings, personal care and pharmaceutical products, food science, paints, anti-icing fluids,...

Stability and Cleansing Function Enhancement of Organic Shampoo by a Vortex Fluidic Device

“…While all samples were homogeneous at the beginning, the original sample was not only fully separated into 2 layers but also with a color change from white to yellow. This shows the poor stability of the original sample, characterized by oil oxidation occurring over the storage period. , The shelf life of conventional shampoo range from 2 to 4 years. , In contrast, organic shampoos exhibit a lower stability compared to conventional shampoos due to their natural ingredients and absence of preservatives. , Organic shampoo contains a higher proportion of natural or plant-based ingredients compared to synthetic or chemical-based ingredients found in conventional shampoos. Natural ingredients can be more prone to degradation, spoilage, or changes in texture and appearance over time, leading to reduced stability. , …”

“…Natural ingredients can be more prone to degradation, spoilage, or changes in texture and appearance over time, leading to reduced stability. 27,28 However, samples subjected to VFD treatment demonstrated improved qualities after 30 days of storage. Although the sample with VFD treatment at 7750 rpm was still separated into two layers of composition with different density, its white color was unchanged after 30 days of storage time, which shows that its oil is well-preserved without oxidation.…”

Boundary Lubrication Performance of Polyelectrolyte–Surfactant Complexes on Biomimetic Surfaces

“…More environmentally friendly alternatives to petroleum-based feedstocks are urgently being sought by hair care formulators. These alternatives can be derived from natural sources, but should provide an equal or superior performance . One promising class of sustainable polymers are polysaccharides, such as guar gum, which can be extracted from the seeds of the guar plant .…”

“…These alternatives can be derived from natural sources, but should provide an equal or superior performance. 32 One promising class of sustainable polymers are polysaccharides, 1 such as guar gum, which can be extracted from the seeds of the guar plant. 33 Guar gum is used extensively in food products as a texture and rheology modifier and its derivatives, such as cationic guar gum (CGG), have become increasingly important in several industries, such as oil and gas extraction as well as textile and paper processing.…”
