Preparation and evaluation of semi-permanent hair dyes liposome

Abstract

This study used phospholipids from fresh egg yolks to prepare liposome-encapsulated semi-permanent hair dyes in different pH buffer solutions and evaluated the functions and colour fastness to washing of the dyes. The extraction ratio of egg yolk phospholipids was 5%, and the purity was 91.8%. Empty liposome solutions were then prepared using high-speed homogenizer with particle size 219-848 nm. After being stored at 4 °C for 28 days, the average particle size of the liposome-encapsulated dye formulas increased from 1.36-1.92 µm to 1.99-2.38 µm. The ΔE colour difference values of the five hair extension sets dyed with the control group and hair dyes on the market were of the range 6.56-13.39 after eight times of washing, whereas the ΔE values of the four hair extension sets dyed with the liposome-encapsulated dyes were of the range 3.56-5.21 after eight times of washing. The liposome-encapsulated dye at pH 3 showed the best result.

Protection of hair color with pomegranate peel extract‐loaded liposomal formulation: Preparation, characterization, and ex‐vivo activity studies

“…This lipids are very essential for the skin and also they could bound the keratin of hair layer. 11,12 It was shown that preventing colors in liposomes, protect hair color from washing and styling because of solubility properties of lipids. Dyes in liposomes improves the hair moisture balance, softness, and strength, also.…”

Low-Salt or Salt-Free Dyeing of Cotton Fibers with Reactive Dyes using Liposomes as Dyeing/Level-Dyeing Promotors

“…Liposomes or phospholipid vesicles are amphoteric compounds containing both polar and nonpolar groups 2,3 . Liposomes are the assembling structures formed by surface-active biological lipids that are arranged with hydrophilic polar head groups exposed to the aqueous phase and hydrophobic fatty acid chains adhered together in the bilayer 4,5 .…”

<b>Assessment on the Effects of Liposome-encapsulated Thioglycolic Acid on Hair Perming</b>

“…Currently, liposomes are used in environmentally conscious fabric processing procedures in the textile industry to encapsulate dye molecules, in order to reduce environmental pollution ; the related processing techniques have already exhibited promising results [5]. Such liposome-encapsulated dye formulations have demonstrated outstanding coloring effects on coloring protein fibers, such as wool and silk, as liposomes enabled the formulations to dissolve fast, which increased the effectiveness of the coloring processes and also improved the antistatic and antishrinkage effects of the fabrics [6,7,8].…”
