The aim of the research was an attempt to apply waste raw materials (oat bran and wheat bran) to cosmetic scrubs. On the basis of literature reports and our own research, original formulations were developed for cosmetics containing the additives in question as an abrasive. The developed cosmetics were in an anhydrous form and contained vegetable fats and skin-sensitive surfactants. Only upon use did they come into contact with water and form an emulsion that, after abrading the epidermis, took care the skin. The reference point in the evaluation was a high-quality commercial product. The functional properties of the obtained cosmetic prototypes were evaluated: stability, viscosity, yield point, skin moisturization, and sensory analysis of the developed formulations. Based on the study, it was found that scrubs containing the addition of oat bran had more favourable rheological and sensory properties, and showed a higher degree of skin moisturization two hours after washing the product off the skin, compared to a commercial product.

Scrub bars are an innovative alternative to traditional liquid, semi-liquid, and oily body scrubs. Through the elimination of water from their formulas, they align with the current ‘waterless’ trend in the cosmetics market. The aims of this study were to create anhydrous formulations for body scrub bars and to assess their physical, chemical, and sensory characteristics depending on the type of exfoliant added. A total of five solid body scrub formulations were developed using different natural exfoliants: sugar, microcrystalline cellulose, ground coffee beans, corn granules, and sodium chloride. The shape and dimensions of the exfoliant particles were characterized by scanning electron microscopy (SEM). The formulations were subjected to texturometric tests. The final products underwent color assessment along with a consumer evaluation of sensory appeal. The test results showed that the body scrubs exhibiting the highest hardness and adhesive force were those containing exfoliants with small particles, either angular (sodium chloride) or subrounded (Coffea arabica seed powder) in shape. Conversely, the lowest hardness was determined for the product formulated with the addition of an exfoliant with well-rounded particles (microcrystalline cellulose). Among the exfoliants tested, microcrystalline cellulose proved to be the most suitable for body scrubs, demonstrating superior texture and exfoliating effectiveness. However, cosmetics containing ground coffee received the highest esthetic ratings. Coffee gave the product a natural color and an appealing scent, as judged by the testers.

The aim of the research was an attempt to obtain cosmetic care masks containing powdered waste leaves from red and green tea. On the basis of literature reports and our own research, original cosmetic formulas containing the addition of teas and the technology for their manufacture had been developed. Before incorporating the tea raw material into the cosmetic, it was dried to an adequate level of dryness and ground to a powder. The reference point in the evaluation was the base mask (without the addition of teas). Next, the functional properties of the cosmetic prototypes were evaluated. Viscosity, yield point, and skin moisturization were evaluated, and a sensory analysis of the developed masks was carried out. Based on the study, it was found that the masks containing the addition of powdered tea leaves had more favourable rheological and sensory properties, and showed a higher degree of moisturization two hours after washing the product off the skin, relative to the base mask. Celem badań była próba uzyskania pielęgnacyjnych maseczek kosmetycznych zawierających sproszkowane odpadowe liście zielonej i czerwonej herbaty. Na podstawie doniesień literaturowych oraz badań własnych opracowano oryginalne receptury kosmetyków zawierających dodatek herbat oraz technologię ich wytwarzania. Przed włączeniem surowca herbacianego do kosmetyku był on suszony do suchej masy i zmielony w młynku na proszek. Punktem odniesienia w ocenie była maska bazowa (bez dodatku herbat). Następnie oceniono właściwości użytkowe prototypów kosmetyków. Oceniono lepkość, granicę płynięcia, nawilżenie skóry oraz przeprowadzono analizę sensoryczną opracowanych maseczek. Na podstawie badań stwierdzono, że maseczki zawierające dodatek sproszkowanych liści herbaty miały korzystniejsze właściwości reologiczne i sensoryczne oraz wykazywały wyższy stopień nawilżenia dwie godziny po zmyciu produktu ze skóry, w porównaniu do maseczki bazowej.

The study addressed the effect of the structure of silicone polyethers on selected functional properties of cotton fabric rinsed in conditioners containing the additives under study. Fabric softener formulations containing two comb-structured compounds (PEG/PPG-14/0 Dimethicone and PEG/PPG-20/20 Dimethicone) and one block-structured compound (Bis-PEG/PPG-20/20 Dimethicone) were developed. Cotton fabric rinsed in conditioners containing silicone glycols was not found to be affected by yellowing. However, differences were noted in the softening ability and re-wettability of rinsed fabrics due to diverse structures of the additives used. The most desirable soft hand effect was observed after cotton rinsing in fabric softeners containing the block-structured compound Bis-PEG/PPG-20/20 Dimethicone. In contrast, the highest fabric re-wettability was shown for the conditioner enriched with a comb-structured compound (PEG/PPG-20/20 Dimethicone). The study results demonstrate that the prototypical fabric softeners containing silicone derivatives have a potential to provide quality characteristic required by consumers of this product group.
