“…The results demonstrate that addition of a hydrophobic extract of blackcurrant seeds to HDLs contributes to a reduction of their potential for irritation of the skin of the hands. The literature data (14,(28)(29)(30)(31)(32)(33) show that the skin-irritating activity is mainly attributable to surfactant monomers. Above the CMC, micelles start forming in the solution, and the number of 'free' monomers is markedly reduced.…”

“…Additives used for that purpose comprise protein hydrolysates, polymers and special types of anionic (14), amphoteric or nonionic surface active agents (1)(2)(3)(4). 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 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.

The effect of a sulfonic acid derivative of alkyl polyglucosides on the safety of hand dishwashing liquids was assessed. In this study, it was found that an increase in the concentration of the natural origin raw material in samples led to a decrease in the zein number, and reduced changes in the pH level of bovine serum albumin solution, compared to a reference sample formulated without these compounds. These findings suggest a high level of reduction in the skin‐irritation effect after applying hand dishwashing liquids. In addition, the application of this type of anionic surfactants in products decreases their ability to emulsify fats. Consequently, the skin‐drying effect produced by the washing process and removal of protective epidermal lipids may be significantly reduced.

Gemini salts of linear alkylbenzene sulfonate (LABS) were prepared by neutralization of sulfonic acid with a series of low-molecular-weight diamines in aqueous solution. The equilibrium surface activity of Gemini salts of LABS was determined by measuring the surface tension as a function of surfactant concentration to determine the critical micelle concentration (CMC), surface tension at the CMC (γ CMC ), and the area per molecule at the air-water interface (Å 2 ). Electrical conductivity was measured as a function of surfactant concentration to determine the CMC and counterion binding. Dynamic surface tension was measured using a bubble pressure tensiometer to infer the rate at which the surfactant migrates to the air-water interface. Equilibrium interfacial tension against mineral oil was measured using a spinning drop tensiometer. Dynamic interfacial tension was measured using a drop volume tensiometer. The surface tension, CMC, and interfacial tension of Gemini salts of LABS decreased compared to monovalent organic and inorganic salts. The CMC decreases with increasing molecular weight of the diamine spacer group. Dynamic surface and interfacial tension of Gemini salts of LABS are lower than monovalent salts. The foam volume of Gemini salts of LABS was determined using a high shear blender test. The foam volume of Gemini salts of LABS is lower than monovalent salts and depends on the size of the spacer group. Hard-surface cleaning was measured using artificial soil applied to white Formica tiles. Soil removal was determined by optical reflectance as a function of abrasion cycles. Gemini salts of LABS show reduced hard-surface cleaning performance compared to monovalent salts. Detergency of different types of soils on cotton and polyester/cotton fabric was determined by optical reflectance measurements. Gemini salts of LABS show improved cleaning performance compared to monovalent salts. Cleaning performance increases with increasing molecular weight of the diamine spacer group. In situ neutralization of LABS with organic diamines is a simple and efficient way to prepare anionic Gemini surfactants for industrial scale applications.
