Natural acidic lipids, such as PS, PG, PI, PA phosphatidic acid and cardiolipin CLare added when anionic liposomes are desired, and cholesterol is often included to stabilize the bilayer. These molecules are derivatives of glycerol with two alkyl groups and one amphoteric group [ 34 ].

Phosphatidylcholine is the biological lipid most widely used for producing liposomes. Liposomes based on phosphatidylcholine consist of phosphatidic acid and glycerin, with two alcohol groups esterified by fatty acids and a third group esterified by phosphoric acid, to which the amino alcohol choline is added as a polar group [ 3449 ].

According to Barani, Montazernormally four different methods can be used for the preparation of liposomes: Dry lipid film; Micelle-forming detergents; Alcohol injection technology [ 34 ]. Liposomes have two distinct roles: They are promising candidates for adjuvant and carrier systems for drug delivery, are well-documented, and can be used for the same purpose in textile materials [ 33 ].

Encapsulation or liposome technology is applied in numerous fields, such as in pharmaceuticals, cosmetics, foods, detergents, textiles and other applications where it is important to liberate the encapsulated material slowly [ 3450 ].

This new clean technology has already been adopted by some textile industries [ 52 ]. In recent years, liposomes have been examined as a way of delivering dyes to textiles in a cost-effective and environmentally sensitive way [ 56 ].

Conventional dyeing processes consume a great deal of energy, a significant amount of which is wasted in controlling the process parameters in order to achieve uniform results.

With respect to the carrier role of liposomes, they can be used in several textile processes such as textile finishing and dyeing, with several types of dyes and fibers.

They are nontoxic, biodegradable, and can encapsulate a wide range of solutes [ 34 ]. Low temperature gives a more natural feel and improved quality, with lower environmental impact [ 34 ]. In recent years, liposomes have been used in the textile industry as a carrier for auxiliary materials leveling, retarding and wetting agents in dyeing, mainly for wool dyeing, and for finishing processes [ 3455 ].

One of the most common problems with textile auxiliaries is that they fail to form a complex in the solution bath. This problem can be solved by using liposomes with selected positive or negative charges. Liposomes can be prepared according to the type of process, solute material and fiber structure [ 34 ].

Liposomes from phospholipids have been widely used as a dye carrier in the dyeing process, and create eco-friendly textile processes. Due to their structural properties, liposomes can encapsulate hydrophilic dyes reactive, acid and basic dyes in the aqueous phase, and hydrophobic dyes disperse dyes in the phospholipid bilayers [ 58 ].

Liposomes containing a dye are generally large, irregular and unilamellar [ 50 ].

A wetting agent is required in the conventional bleaching bath of cotton fabrics, but this step can be eliminated by using liposomes. The presence of liposomes in the peroxide bleaching bath can improve the mechanical properties of fabrics and their brightness.Synthetic definition, of, pertaining to, proceeding by, or involving synthesis (opposed to analytic).

What is Olaplex? Olaplex is a line of hair repair, “bond building” treatments that’s getting heaps of buzz in the hair community, especially with people who have damaged hair from excessive bleach.

It’s available in a couple of forms – Olaplex can be mixed in with bleaching products to minimise damage, or it can be used as a separate treatment.

The dyes were applied to cotton fabric using pad-batch, pad-dry-cure, and exhaust dyeing methods. Bis-DCT bifunctional reactive dyes were applied to cotton by a pad-batch method, since the dichlorotriazine reactive groups are highly reactive and can be applied at room temperature. The synthesis of azo dyes in SC-CO2 was dependent on a combination of basicity, solubility and steric hindrance around the amino group to be diazotized. The second part involved optimization of the reaction yield of a vinylsulfonyl-based disperse reactive dye via a statistical design of experiment. Abstract. Indocyanine green (ICG) is a near-infrared dye that has been used in the clinic for retinal angiography, and defining cardiovascular and liver function for over 50 years.
