The search for suitable packaging for cosmetics is an important topic. Lengthy stability tests have been conducted to verify the protective function of recyclable and more sustainable packaging materials. An innovative shelf-life modelling tool enables manufacturers to predict the durability of their products in the future. The choice of packaging materials depends on the product's requirements, particularly in terms of light protection, oxygen, and water vapor barrier. Recyclable and sustainable packaging is demanded, but it may have different barrier properties than conventional multilayer packaging. The text describes how a cream was produced using sunflower oil as the fat phase. The cream was enriched with various extracts such as citrus, hemp, hops, and Riesling. It was found that the cream with Riesling extract had low oxidation and was sensorially indistinguishable from the reference cream. However, the cream with hops extract showed a higher oxidation rate than the other extracts. The influence of different packaging materials on oxidation was also examined. PET and PBS had slower oxidation, while PP had faster oxidation. This study investigates the oxidation of creams with hops extract and their durability in various packaging materials. It is noted that the sensory acceptance limit of the cream in recycled PP tubes is reached after 100-150 days, while this is the case for sustainable PBS only after 450-500 days. For bottles, the limit for recycled PP is reached after 150-200 days, while PBS ensures good quality even after 600 days. The results show that for the oxidatively sensitive formulation with hops extract, a short shelf life with recycled PP tubes and a declared shelf life of 30 months with sustainable PBS bottles is recommended.

This longitudinal study investigates the effects of three transfer concepts on the use of formative assessment in primary school reading lessons. Here, the mediating role of acceptability and perceived feasibility (of the feedback and diagnostic materials) as well as cooperation between teachers is analyzed. In the control group (CG, n = 14) teachers were provided with a comprehensive package of worked-out materials. In the first experimental group (EG I, n = 29) three supplementary training courses were conducted. In the second experimental group (EG II, n = 30), in addition, school-internal measures were implemented via a multiplier approach. Results of path analyses of survey data show that, in comparison to the CG, the additional participation in the training courses (EG I) can foster the use of materials (β =.75, p <.05; f ² =.059), while there is no positive effect of the supplementary implementation of school-internal measures (EG II). Perceived feasibility (β =.30, p <.05, =.019) and especially cooperation (β =.31 –.37, p <.05, Ũ =.020 –.028) have a central mediating role for the success of transfer. [ABSTRACT FROM AUTHOR]

The article "Sustainable Packaging for Cosmetics and Cleaning Products: Group Interview with rezemo, cosnova, and Eurofins" features an interview with various companies about their packaging materials and sustainability measures. Stefan Zender from rezemo explains that they only use fully plant-based materials, mainly wood fibers from sustainable forestry. Daniela Soukup from cosnova states that they primarily use plastics and glass, depending on the product group and packaging type. Both companies are working on making their packaging more sustainable by reducing materials and seeking recyclable options. However, there are technical challenges, especially when it comes to the use of applicators, which make complete recyclability difficult. The use of recycled packaging poses safety risks, particularly regarding substance migration. The companies emphasize the importance of fully plant-based materials and the establishment of recycling infrastructures. Natural materials such as paper, grass, cork, and wood are considered potential solutions, but there are also challenges in controlling ingredients. [Extracted from the article]

The Forest quarantine laboratory at Julius Kühn-Institut in Braunschweig (Germany) curates a unique collection of living Bursaphelenchus species, permanent slides and ITS-RFLP profiles. The collection was initiated by Dr. Helen Braasch and currently comprises 48 species in 308 different isolates. These isolates were collected over 30 years across the globe from various habitats and sources, like forest trees and wood imports including wooden packaging material. Cultivation of the nematodes on sporulating and non-sporulating Botrytis cinerea is sophisticated, labor-intensive and requires both, experience and patience. [ABSTRACT FROM AUTHOR]
