The effect of selected supercritical CO₂ plant extract addition on user properties of shower gels

Abstract

The formulations of washing cosmetics i.e. shower gels, containing extracts obtained during supercritical CO 2 extraction process as active ingredient, were developed. The subject of the study was the analysis of the physicochemical and user properties of the obtained products. In the work supercritical CO 2 extracts of black currant seeds, strawberry seeds, hop cones and mint leafs were used. The formulation contains a mixture of surfactants (disodium cocoamphodiacetate, disodium laureth sulfosuccinate, cocoamide DEA, cocoamidepropyl betaine, Sodium Laureth Sulfate). Various thickener agents were applied to the obtained desired rheological properties of the cosmetics. Among others, sorbitol acetal derivatives, methylhydroxypropylcellulose and C10-30 alkyl acrylate crosspolymer were used. For stable products, the effect of extracts addition (black currants seeds, strawberries seeds, mint and hops, obtained from supercritical CO 2 extraction process) on the cosmetics properties, such as pH, viscosity, detergency and foam ability, were determined. The obtained results showed that the extracts could be used as components of shower gels.

Humulus lupulus L. as a Natural Source of Functional Biomolecules

“…In cosmetics, hops are used in bath lotions, among others [80]. Vogt et al [17] used supercritical CO 2 extracts of hop cones to formulate shower gels, and the results obtained showed that their addition enhanced their skin-conditioning properties due to their content in bioactive ingredients. Moreover, the formulations containing the extract of hop cones present compounds to treat oil and dandruff in hair.…”

“…Moreover, the formulations containing the extract of hop cones present compounds to treat oil and dandruff in hair. The use of hop extract in hair cosmetics is supported by its antifungal and antiseborrheic properties that decrease its brittleness, nourish it, give it shine, increase its strength, and prevent its loss [17].…”

“…Taking the above into account, and the current trend of searching natural compounds with novel biological properties, the wealth of the hop in bioactive compounds makes it an excellent source to extract biologically active molecules with multiple applications in the alimentary, pharmaceutical, and nutraceutical industries [12,15,[17][18][19][20]. This has promoted intense research in the field of bioactive compounds from hops that allows on the one hand achieving high yields and on the other hand keeping the bioactivities of the extracted compounds.…”

Recent Advances in Supercritical Fluid Extraction of Natural Bioactive Compounds from Natural Plant Materials

“…SC-CO 2 has been used for the isolation of antioxidants and parabens from cosmetic products [ 130 ]. Vogt et al [ 131 ] investigated the extract of blackcurrant seeds, strawberry seeds, hop cones, and mint leaves obtained by SC-CO 2 for the production of shower gels and shampoo, and the result showed that those natural extracts could be used as ingredients in shower gels.…”

Caracterización del ecotipo de lúpulo (Humulus lupulus L.) chileno Ranco en la Región de Los Ríos

“…In cosmetics, hops are used in bath lotions, among others (Cieśliński and Idowski, 2003;Astray et al, 2020). Supercritical CO 2 extracts of hop cones were used to formulate shower gels resulting in enhanced skin-conditioning properties due to their content in bioactive ingredients (Vogt et al, 2014). Moreover, the formulations containing hop cone extract have compounds that treat oil and dandruff in hair.…”
