washes. Notably, body wash formulations with Pentavitin have been shown to deliver optimum skin hydration for seven days, while shower gel formulations with Pentavitin have been shown to prevent skin cleansing associated dryness and significantly boost hydration for 24 hours and longer, and to strengthen the skin barrier. Personal Care will publish these findings in an upcoming issue. Pentavitin can be used in multiple


applications and is an ideal candidate for rinse- off formulations that both cleanse and hydrate the skin – a still unmet consumer need. DSM’s own line-up of ready-to-use formulations includes shampoos, shower gels and washes, and also newer products that are growing in popularity such as micellar water and mousse cleansers. Evonik has introduced Antil 500 Pellets, a


novel and versatile rheology modifier for various cleansing formulations. As an innovative hydrophilic polymer, Antil


500 Pellets enables a significant reduction of the active surfactant level in standard cleansing formulations. In addition, the efficiency and high flexibility of Antil 500 Pellets facilitate the thickening of challenging surfactant systems, such as sulfate-free formulas, effectively supporting the trend for milder cleansing in personal care. The 100% active, preservative-free solid


is clearly soluble in water and processable at room temperature. Furthermore, they are stable against hydrolysis and effective over a wide pH range. The thickening agent provides a rich formulation texture with Newtonian flow behaviour but without changing the foaming characteristics, which is essential for fulfilling the consumers’ sensorial expectations of personal cleansing products. The coronavirus pandemic has brought


attention to hygiene and disinfection. The virucidal activity of L(+)-lactic acid against enveloped viruses, including coronavirus was investigated with the European standard test method EN 14476. The modified vaccinia virus Ankara (MVA) acts as representative virus for all enveloped viruses including coronavirus. The test was conducted at 20°C under


dirty conditions. The test criterion, a ≥ 4 log10 www.personalcaremagazine.com


reduction (≥ 99.99 % inactivation) of the MVA titre within the recommended exposure period, is passed for the following L(+)-lactic acid concentrations in water: 0.90 % L(+)-lactic acid at a exposure time of 1 min. 0.45 % L(+)-lactic acid at a exposure time of 5 min. These results show Jungbunzlauer L(+)-lactic acid has “virucidal activity against all enveloped viruses- incl. corona virus”. Further tests are being conducted. Jungbunzlauer L(+)-lactic acid is a natural,


sustainable and less hazardous ingredient in the formulation of surface disinfectants and antimicrobial hand soaps. It is derived from renewable raw materials via fermentation and is readily biodegradable. Jungbunzlauer L(+)-lactic acid conforms to


Regulation (EU) 528/2012 (biocidal products regulation) and can be used as a biocidal active substance for product types (PT) 1, 2, 3 and 4. Test results obtained for antiviral (EN14476) and antibacterial (EN1040, EN1276 and EN13697) disinfection applications are available. Today, with the situation caused by the spread


of COVID-19, this advice is more evident than ever: the washing of hands can make a real difference when stopping a possible contagion. This makes hand washing and the use of pathogen stopping disinfectant solutions a key action when dealing with the novel COVID-19 virus. Kao offers sanitisng formulations that do not


require rinsing. These formulations include spray- applied hydroalcoholic hand sanitiser, alcohol- free hydroalcoholic hand sanitising gel and foam hand sanitiser, all of which are made with the total absence of aggressive agents on the skin. All these solutions have the moisturising


effect of Levenol H&B to leave hands fresh and soft after application, a necessary property when hand washing is more frequent than usual. It is for this reason, that Kao’s formulas include this surfactant, which is an 100% active liquid specially developed for hair and body formulas with emollient and foaming properties. Kao solutions also offer options for hand


washing with subsequent rinsing. Akypo Foam LM 25 is a mild foaming agent for cleaning products. It is designed to offer an exceptional foam texture during application, ensuring a smooth feel during use.
