ABSTRACT: The majority of natural colourants are of vegetable origin from plant sources –roots, berries, barks, leaves, wood and other organic sources such as fungi and lichens. In the medicinal and food products apart from active constituents there are several other ingredients present which are used for either ethical or technical reasons. Colouring agent is one of them, known as excipients. The discovery of man-made synthetic dye in the mid-19th century triggered a long decline in the large-scale market for natural dyes as practiced by the villagers and tribes. The continuous use of synthetic colours in textile and food industry has been found to be detrimental to human health, also leading to environmental degradation. Biocolours are extracted by the villagers and certain tribes from natural herbs, plants as leaves, fruits (rind or seeds), flowers (petals, stamens), bark or roots, minerals such as prussian blue, red ochre & ultramarine blue and are also of insect origin such as lac, cochineal and kermes. -

It is only recently (the first artificial dye was invented in 1857) that the textile industry has turned to synthetic dyes. Today, many craftspeople are rediscovering the joy of achieving colour through the use of renewable, non-toxic, natural sources. Natural dyes are inviting and satisfying to use. Most are familiar substances that will spark creative ideas and widen your view of the world. Try experimenting. Colour can be coaxed from many different sources. Once the cloth or fibre is prepared for dyeing it will soak up the colour, yielding a range of results from deep jew- el-like tones to dusky heathers and pastels. -

International Journal of Pharmacy and Pharmaceutical Sciences ISSN- 0975-1491 Vol 8, Issue 10, 2016 Review Article REVIEW: FROM SCREENING TO APPLICATION OF MOROCCAN DYEING PLANTS: CHEMICAL GROUPS AND BOTANICAL DISTRIBUTION IMANE ALOUANI, MOHAMMED OULAD BOUYAHYA IDRISSI, MUSTAPHA DRAOUI, MUSTAPHA BOUATIA Laboratory of Analytical Chemestry, Faculty of Medicine and Pharmacy, Mohammed V University in Rabat Email: [email protected] Received: 19 May 2016 Revised and Accepted: 12 Aug 2016 ABSTRACT Many dyes are contained in plants and are used for coloring a medium. They are characterized by their content of dyes molecules. They stimulate interest because they are part of a sustainable development approach. There are several chemicals families of plant dye which are contained in more than 450 plants known around the world. In this article, a study based on literature allowed us to realize an inventory of the main dyes plants potentially present in Morocco. A list of 117 plants was established specifying their botanical families, chemical Composition, Colors and parts of the plant used.

ABSTRACT WANG, GUAN. Synthesis and Application of Bleach Activators
ABSTRACT WANG, GUAN. Synthesis and Application of Bleach Activators Containing Various Cationic Groups and PET Fabric Decolorization using Fenton’s Reagent. (Under the direction of Dr. David Hinks.) CBAs are quaternary ammonium salts (QAS) that are extensively used in various applications. Although most of the QAS are generally believed to be nontoxic to humans, they will harm aquatic life both animals and plants. CBAs are applied in textile bleaching process and the wastewater after bleaching contains chemicals including bleach activators. Even though wastewater contains CBAs will be treated in a wastewater treatment plant, the treated water still contain these chemicals. The study of acute toxicity and genotoxicity of CBAs to aquatic organisms was conducted in this study. Eight new bleach activators and two bench mark cationic bleach activators were investigated. New invented cationic bleach activator 3- PBBC is 86 times less toxic in the Daphnia sp. Immobilization Test, 18 times less toxic in Algae Toxicity assay and 10 times less mutagenic in the Salmonella/microsome microsuspension assay in comparison with the benchmark product (TBBC). This confirmed that replacing the cationic group in CBAs using low toxicity ammines can reduce the toxicity of CBAs to aquatic organisms. An effective low temperature and neutral pH bleaching system was developed using CBAs. A comparison life-cycle assessment for conventional and innovational bleaching system was conducted in this study. Their relative environmental performance was analyzed and compared. Based on data from industry, pre-published research, lab-scale experiments and the Ecoinvent database, the life-cycle-inventory (LCI) for both innovative and conventional bleaching process was developed. -

Writes of Spring
On 20 March 2019 we asked people across the UK to capture the arrival of the first official day of spring and help create a crowd-sourced nature diary. More than 400 people did just that from across the four corners of the UK – celebrating this season of colour and the natural world coming to life. The following pages are a selection of the entries curated by the writer Abi Andrews. Introduction n 2018, my spring was spent in a caravan, in a glade in view of Carningli mountain, Itopped by a rocky grey outcrop with purple heathers, confettied below with vivid yellow gorse. The caravan sat within the Pembrokeshire Coast National Park, in an area that saw an influx of ‘back-to-the-landers’ during the seventies. In it you will find covert, sympathetically built dwellings and cooperative human communities in repurposed farmhouses, lying between woods of bent, blackened oaks, their flamboyant colonies of lichens, and boulders covered with soft and ecstatic mosses. On the moors are strange, stunted Welsh horses, their silhouettes hunched like the simplified animals of Neolithic rock art. Clear spring water gurgles up and silvers everything, running brown through the taps after a heavy rain. At night, owls call to each other. In spring 2019, I was the most attentive to the living world that I have ever been, for the transition of a season. I grew up in suburbia, and moved soon after to a city. Living closer to the land has offered me an anchoring, in noticing the seasons more: the fatigue that comes with winter darkness, the processing of firewood for next year, the harvesting of food — being reminded all the time of the future by preparing for it. -
