“…A 200‐μL aliquot of the solution was applied on a filter paper disc and fitted into an extra‐large (18 mm Ø) Finn Chamber on Scanpor Tape (SmartPractice, Phoenix, AZ, U.S.A.), as recommended . Four chambers were applied to one randomized forearm within 1 min after preparation, and occlusive pretreatment was performed during 24 h. The SLS solution was stored in a refrigerator at 4 °C between use …”

“…A range of studies show that the skin irritation effect is largely attributable to the presence of surfactant monomers in the washing bath [8][9][10][11][12][13][14][15][16][17]. The severity of irritations depends for the most part on the structure of the surfactant molecule and its concentration in the washing bath.…”

“…Studies on the safety of product use published up to the present place a special emphasis on the assessment of negative effects on the skin of the hands induced by model surfactants, particularly sodium lauryl sulfate (SLS) [7][8][9][10][11][12][13][14][15][16][17]. It has been determined that surfactants interacting with the stratum corneum can cause tissue swelling, wash away water-soluble small molecular components of the stratum corneum, and inactivate enzymes [7][8][9][12][13][14][15][16][17]. Based on scientific studies in the area, it has been suggested that the main factor contributing to the negative effect of surfactants on the skin of the hands is the presence of free surfactant monomers in the washing bath [9,10,[12][13][14][15][16][17].…”

Such molecules are able to interact relatively easily with proteins found in the skin, causing undesirable skin irritations.…”

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.

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.
