“…The avoidance of organic solvents, the homogeneous distribution of an active component throughout the whole polymer volume, the absence of an effluent generation and lower energy demands comparing to conventional impregnation processes are the main features of this technique [35,36]. In our previous report [37], large potential of the SSI technology in the domain of repellent materials fabrication was disclosed. SSI was found to be a feasible technique for manufacturing of cotton fabrics functionalized with pyrethrum extract aimed for clothing.…”

“…Considering the growing consumer ecological awareness and the today’s concern about palm oil’s environmental profile [ 19 , 20 ], there is ongoing research for additives with less environmental impact. In this context, apart from natural components [ 21 , 22 ], the use of hydrophilic polymers can play a crucial role. Hydrophilic polymers and copolymers exist in fabric softeners.…”

Fabric conditioners are household products used to impart softness and fragrance to textiles. They are colloidal dispersions of cationic double chain surfactants that self-assemble in vesicles. These surfactants are primarily derived from palm oil chemical modification. Reducing the content of these surfactants allows to obtain products with lower environmental impact. Such a reduction, without adverse effects on the characteristics of the softener and its performance, can be achieved by adding hydrophilic biopolymers. Here, we review the role of guar biopolymers modified with cationic or hydroxyl-propyl groups, on the physicochemical properties of the formulation. Electronic and optical microscopy, dynamic light scattering, X-ray scattering and rheology of vesicles dispersion in the absence and presence of guar biopolymers are analyzed. Finally, the deposition of the new formulation on cotton fabrics is examined through scanning electron microscopy and a new protocol based on fluorescent microscopy. With this methodology, it is possible to quantify the deposition of surfactants on cotton fibers. The results show that the approach followed here can facilitate the design of sustainable home-care products.

“…Consequently, they retain the majority of active substances in a practically unchanged form. There are literature reports evaluating the effect of plant extracts produced under supercritical CO 2 conditions on the properties of various household chemical products (Jang and Lee, ; Pajnik et al, ; Seweryn et al, ; Wasilewski et al, , b, c, d). In their studies, Wasilewski et al (Seweryn et al, , Wasilewski et al, , b, c, d) used hydrophobic supercritical CO 2 plant extracts in hand dishwashing liquids.…”

“…In addition, in line with current trends, fabric softeners that are widely available on the market contain additional, naturally sourced ingredients such as plant extracts or oils or fats of animal origin (lanolin). These raw materials are intended primarily to enhance the fabric softening effect (Jang and Lee, 2010;Lai, 2006;Murphy, 2015;Pajnik et al, 2017;Smulders, 2002;Wasilewski et al, 2016a;Zoller, 2008), but they may also have a positive impact on the condition of the skin during the use of fabrics after the rinsing process (Hermanns et al, 2001;Isoda et al, 2011).…”

“…There are few publications suggesting the possibility of formulating fabric softeners with the addition of plant extracts obtained by supercritical carbon dioxide extraction (Pajnik et al, ; Wasilewski et al, ). Importantly, however, there are no literature reports on the application of supercritical CO 2 plant extracts in transparent fabric softeners.…”

This article investigates the effect of hydrophobic supercritical CO2 raspberry seed extracts on the physicochemical and functional properties of a modern, transparent fabric softener. The addition of a hydrophobic extract to a transparent softener formulation increased the turbidity and dynamic viscosity of the product compared to the reference formulation (with no added extract). In addition, fabric rinsed in a bath containing the transparent fabric softener enriched with the hydrophobic extract was characterized by a higher degree of softness and slightly lower values of fabric rewettability (two parameters determining the usable properties of this type products) in relation to the values determined for a fabric exposed to the rinsing process in an aqueous solution of the transparent fabric softener without added extract. The results obtained in the assessment of physicochemical properties point to the modification of the structure of fabric softener resulting from the growth of surfactant aggregates due to solubilization of the hydrophobic extract. As a consequence, the deposit—an adsorption layer of surfactants (responsible for key characteristics relevant to the performance of this type of products) remaining on the fabric after the rinsing process—is modified.
