“…The presence of such additives typically lowers the critical micellization concentration, increases the size of micelles (hindering their penetration into the skin) and stabilizes them thermodynamically (reducing the number of micellar aggregate decompositions). The above processes entail a decrease in monomer concentration in the solution, which reduces the potential for skin irritation (6)(7)(8)(9)(10)(11)(12)(13).…”

“…They are used due to their beneficial foaming properties, high washing power and easy modification of the viscosity of the product in which they are used (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13). Auxiliary surfactants used in HDLs include mainly nonionic compounds (fatty alcohol ethoxylates, alkanolamides, alkyl polyglucosides) and amphoteric compounds (alkylamidopropyl betaines) (7)(8)(9)(10)(11)(12)(13). The primary role of auxiliary surfactants is usually to selectively improve specific product attributes related to both product functionality and safety of use (7,11).…”

The study investigated the effect of hydrophobic, blackcurrant seed extract (Ribes nigrum L.) obtained under supercritical CO 2 conditions on the anti-irritant properties of hand dishwashing liquids. A range of liquids differing in extract concentration (0-0.5 wt%) were prepared. The product prototypes were subjected to tests focusing on their anti-irritating property and functionality. Based on the zein values and measurements of changes in the pH level of the bovine albumin solution, the liquids were shown to be markedly safer to use. It was noted that an increase in extract concentration in a product leads to a deterioration of detergent and foaming properties. The highest concentration of the extract allowing the achievement of acceptable results was 0.3 wt%. The results suggest that hydrophobic plant extract, for example, from blackcurrant seed can be an interesting raw material for reducing the irritating potential of liquid agents designed for hand dishwashing.

“…They found that both the monomers and micelles were able to penetrate into the epidermis [7]. One of the potential means of preventing these adverse effects is the addition of co-surfactants [18][19][20][21][22][23][24][25][26][27], hydrolyzed proteins [28][29][30] or polymers [30][31][32]. The action mechanisms of the additives involve an increase in micelle size or formation of appropriate complexes leading to a decreased concentration of free surfactant molecules in the solution [15,33].…”

We investigated the effect of hydrophobic extract concentration on the safety of using hand dishwashing liquids (HDL). A series of formulations was prepared, differing in the concentration of the hydrophobic chamomile extract obtained in supercritical CO2 conditions (from 0 to 0.7 %). We found that an increase in the concentration of the extract led to a decrease in the zein number, and reduced changes in the pH level of bovine serum albumin solution (i.e., two parameters determining the irritant activity of the formulations). It was also found that the additives reduced transepidermal water loss and improved the skin hydration level. Based on the findings of the study, a mechanism has been proposed, according to which hydrophobic plant extracts form aggregates in the volume phase of the washing bath. The surface of the aggregates is the adsorption area for surfactant monomers responsible for the irritant effect. Increasing the addition of the extract was shown to reduce the negative impact of the formulations on the skin of the hands, thus contributing to a greater safety of use of HDL.

“…2b), except that the plots tended to have an optimal value in the range of n = 16-18. These convex dependences, which have been observed for many ionic surfactants [22][23][24], are complicated and depend on many factors such as surfactant type and experimental conditions, but may be related closely to their hydrophobic and hydrophilic balances [25].

Surface-active properties of cleavable surfactants with a betaine ester group-(n-alkyloxycarbonylmethyl)trimethylammonium chlorides, used as separation reagents-were investigated. Critical micelle concentrations, dispersing powers, and foaming powers were comparable to those of alkyltrimethylammonium chlorides with the same total number of carbon atoms. On the other hand, the solubilities of the four hydrophobic dyes N,N-dimethyl-3-nitroaniline, naphthalene, pyrene, and oil orange SS in the former surfactant solutions were equal to or slightly smaller than those in the solutions of the latter surfactants with the same alkyl chain length. The alkali hydrolysis yields of the formers approached 100% in aqueous buffer solution at pH 10 and 25°C within 10 min, and the yield at pH 9 was dependent on the alkyl chain length. This type of surfactant was also found to be as an efficient separation reagent which disperses carbon black and solubilizes the above dyes into aqueous neutral solution and then separates them instantaneously and almost perfectly as precipitates when a small excess of NaOH is added.
