Renewable, natural, traditional dish wash cleaning materials used in India: an overview

Background India has been using natural, renewable resources for dishwashing and cleaning since pre-Harappan times, which speak to the country’s rich biodiversity and long standing traditions of health and hygiene. The current review focuses on several Indian traditional dish wash materials that are categorized according to their mechanism of action as scrubbers and scrappers, abrasives, degreasers, deodorizers and saponin biosurfactant dish wash cleaning materials. Main body of the abstract Scrubbers and scrappers include rice straw, bagasse, coconut coir, coconut brooms, jute and agave fibers, luffa, etc. Soil, clay, sand, crystal salt, lime, rice husk, bran, starch, ash (wood, dung, husk), charcoal, biochar, and other materials are examples of abrasives. Materials that contain organic acids, such as citrus, mango, gooseberry, tamarind, tomato fruits, are used as degreasers. On the other hand, Citrus peels, drumstick seeds, sour butter milk, etc., come under deodorizers. The saponin biosurfactant rich fruits and seeds of soapnuts, soap pod, green gram, Bengal gram, bitter Albizia , etc., function as surface active agents. A few of them use multiple mechanisms to clean the vessels. They are used in many forms (solid, powder, liquid, paste, sponge, fiber, scrub, broom) and obtained from a variety of plant plants (leaf, bark, stem, fruit, seed) as well as the earth’s crust. Short conclusion Compared to commercial, manmade surfactants, natural organic and biosurfactant cleaners have several major advantages over synthetic ones, such as their natural availability, affordability, renewability, biocompatibility, biodegradability, minimal environmental and human toxicity, hypo-human allergenicity and multifaceted biological activities. They are free from preservatives and carcinogenic byproducts, free from phosphate-induced eutrophication and sustainable in terms of local resource use, fossil fuel independence and low carbon footprint production. In addition to kitchen utensil cleaning, few of them are utilized for their myriad of functionalities such as jewelry polisher, face mask, bathing soap, hair cleanser, hair conditioner and washing detergent. The use of renewable and natural cleaning materials aligns with several United Nations Sustainable Development Goals, including Goal 6, Goal 9, Goal 12, Goal 13, Goal 14 and Goal 15.


Background
India is well known for its gastronomy, traditional cookware, culinary techniques and skills; customs, traditions and rich cultural heritage.Exploitation of a variety of locally sourced, renewable materials is linked to economical, medical, culinary, cultural, environmental and religious benefits (Kora 2019a(Kora , b, 2020b)).The current review briefs about the several natural, traditional dish wash cleaning materials that are available and used in India, *Correspondence: Aruna Jyothi Kora koramaganti@gmail.com;koraaj@barc.gov.in;ajkora@hbni.ac.in 1 National Centre for Compositional Characterisation of Materials (NCCCM), Bhabha Atomic Research Centre (BARC), ECIL PO, Hyderabad 500 062, India 2 Homi Bhabha National Institute (HBNI), Anushakti Nagar, Mumbai 400 094, India in terms of their classification, properties, importance and applications.Since pre-Harappan civilization, India has used renewable, natural materials, such as saponiferous fruits (Sapindus sp., Acacia concinna, Phyllanthus emblica) as hair cleanser, detergent and dish wash cleaner.This shows the country's rich biodiversity and the long standing, hygienic customs that are ingrained in Indian culture (Kora 2022).
Due to their inherent antibacterial properties, copper and brass utensils are frequently used in traditional Indian homes, helping to maintain clean and hygienic dishes (Singh and Goel 2021).Because natural cleaning products and agricultural residues are readily available, affordable and environmentally friendly, the habit of using them for dishware cleaning has been passed down through the generations in many Indian communities, particularly in rural regions (Lawagon and Amon 2019).The community knowledge and expertise contribute to the preservation of these ecofriendly cleaning practices (Wisetkomolmat et al. 2021).With a growing focus on sustainable living and environmental consciousness, there is a renewed interest in using natural dish wash cleaning materials in contemporary Indian homes as well.Nowadays, a lot of people are looking for environmentally responsible alternatives to commercial, store bought detergents and traditional Indian cleaning techniques serve as an inspiration for adopting natural and sustainable methods for dishwashing and household cleaning.
Concerns have been raised regarding the antimicrobial preservative triclosan, which is a common ingredient in commercial dish washing solutions.These concerns stem from the preservative's residual concentration on dishware, its interaction with chlorinated water, which can lead to the formation of trihalomethane, sunlight-induced chlorinated dioxin formation and the development of triclosan resistance in microbes (Tsai et al. 2008).Furthermore, phosphate-induced eutrophication of aquatic bodies such as lakes, ponds, rivers and estuaries is not caused by natural dish wash cleaners (Kora et al. 2019;Van Hoof et al. 2017;Tusseau-Vuillemin 2001).Another antimicrobial preservative, paraben (methyl, ethyl, propyl, butyl, benzyl) and alkanolamines and ethanolamine (mono, di, tri) found in household cleaners function as endocrine-disrupting compounds (EDC) (Eriksson et al. 2008;Gluberman et al. 2016).The commercial dish wash cleaners are known to contain potential human carcinogenic byproducts, contaminants and solvents such as 1,4-dioxane.It is formed during the synthesis of ethoxylated surfactants and has limited biodegradability (Hayes Table 1 The list of different plants, in terms of their common name, scientific name, taxonomic family, used parts and used forms as scrubbers and scrappers In both developed and developing nations, regular use of household dish wash detergents and cleaners has been attributed to localized eczema/atopic contact dermatitis/ allergic contact dermatitis and irritation on hands and skin in home makers, domestic workers, kitchen workers, nursing staff, children, etc. (Austoria et al. 2010;Grammer-West et al. 1996;Rungta 2015;Eriksson et al. 2008).The detergent-induced skin irritation potential of different Indian laundry and dish wash household detergents was investigated using 24 h screening patch test.The study revealed varying levels of erythema, scaling and edema in terms of total irritancy score (Austoria et al. 2010).Some of the ingredients found in household dish wash cleaners are known to exhibit toxicity toward marine bioluminescent symbiotic bacteria (Aliivibrio fischeri), crustaceans (Daphnia magna, Artemia), freshwater zebra fish (Danio rerio).They are used as model test organisms for various toxicological assays and suspected carcinogens (Nhat Do et al. 2019).

Natural dish wash cleaning materials used in India
Although convenience and marketing have made modern dish washing soaps and detergents more widely available in cities, the paradigm has shifted in favor of natural dish wash cleaning materials that are free of synthetic chemicals, compostable, biodegradable, plastic free, handmade, locally sourced and packaged with no waste.In the fight against pollution and climate change, this might result in the resurgence of conventional alternative cleaning materials in the future.Both commercial and traditional dish wash cleaners are available and also made in a variety of forms, such as fibrous (coir), sponge (luffa), bunch, thread, brooms, pads, scrub, brush, bar, powder (ash), paste and liquid (Earthbits.com 2023).Based on surface, texture, chemical composition and applicability, the natural dish wash cleaning materials can be classified under

Scrubbers and scrappers
Natural plant cleaning materials with large, coarse surfaces and abundant in cellulose such as paddy straw, sugarcane bagasse, corn cob, bamboo stem sticks, stem and panicle inflorescence brooms of thorn grass (Aristida setacea) and tiger grass (Thysanolaena latifolia), leaf and leaf midvein brooms (toddy, coconut), plant fibers (coconut, jute, roselle, agave, banana), luffa, coconut shells, groundnut shells (Kora 2019b(Kora , 2022;;Niveditha and Yadav 2016;Da-Costa-Rocha et al. 2014) are used as scrubbers for kitchen utensils, countertops and walls (Fig. 1).Additionally, animal materials especially calcareous shells of bivalve mollusks (mussel, oyster, clam) and chitinous exoskeletons of crustaceans (crab) are used for scrapping the milk residues and soiled utensil surfaces (Fig. 2).For instance, natural luffa sponge also known as cleaning sponge obtained from the dried fibrous fruit mesocarp of sponge gourd species (Luffa aegyptiaca, L. acutangula) is widely used as kitchen sponges for cleaning utensils, counter tops, tables, etc., and as bath sponge and scrub (Wisetkomolmat et al. 2021;Eenadu 2023a).Certain materials are occasionally preferred for use in particular cleaning applications.For example, rice straw is used for scrubbing rice cooked clay pots, while coconut and thorn grass brooms for scrubbing cast ion and clay pots.The scrubbers can be used either directly or made into various forms such as pads, brushes, scrubs, bunches, cords, ropes and brooms (coconut, toddy, thorn grass, Tiger grass) (Earthbits.com 2023).
The list of various plants along with their common name, scientific name, taxonomic family, usable parts and used forms as scrubbers and scrappers are given in Table 1.Scrubbing involves physical mechanical action requiring force to remove dirt, grime and food residues from the kitchen utensil and countertop surfaces.The friction created by the scrubs in the form of pad, brush, sponge and broom against the surface being cleaned is helpful in dislodging and lifting the food particles and stains.
Certain abrasives are specifically used for thorough cleaning; for example, Multani mitti (Fullers' earth) is used as a natural skin and hair cleanser and as a cleaner for greasy kitchenware cleaner due to its abrasive and high oil and grease absorption qualities; lime (calcium oxide) is used for soot, tar, grease and stain removal from glass, glass chimney and silverware due to its alkaline and abrasive nature (Yenugu 2014); rice bran is employed for aluminum vessel cleaning because of its abrasion, oil and grease absorption and polishing properties; salt is employed for polishing copper, silverware (Aguirre 2022), starch is utilized for greasy dishware washing due to oil absorptive character (Aguirre 2022) and ash is used for silverware polishing due to its abrasion, absorption and detergent action attributed to potassium carbonate and potassium hydroxide presence (Balasubramanyan 2021; Lawagon and Amon 2019), etc.In India, ash obtained from wood, dung and rice husk, and charcoal are also utilized as dentifrice (Sekhar 1961).Moreover, the red ochre known as gairika is used as a dentifrice in a number of Indian Ayurvedic toothpaste and tooth powders.The list of many traditional cleaning abrasives, in terms of their common name, Indian names, chemical constituents and cleaning applicability are given in Table 2.

Degreasers
Organic acid rich, sour tasting materials, such as tamarind fruit mesocarp/pulp (fresh, dried), Citrus fruit mesocarp and juice; fruit pulp and juice of mango, Indian gooseberry (amla), star gooseberry, tomato, Carandas plum (vakkaya), leafy greens of tamarind (chinta chiguru), roselle (gongura), garden sorrel (chukka kura), creeping wood sorrel (pulichinta); curd, sour butter milk are the frequently used traditional, natural degreasers (Figs.   C. reticulata (sweet orange) are the three Citrus fruits of the Rutaceae family that are most frequently used for degreasing (Kora 2022;Aguirre 2022).The natural acidic materials that are abundant in organic acids, including citric acid, acetic acid, tartaric acid, oxalic acid, malic acid, ascorbic acid, fumaric acid, lactic acid, etc., serve as effective degreasers.The organic acids are used to remove and dissolve grease, tough stains, mineral deposits and odors from clay, aluminum, stainless steel (SS), copper, brass and silver kitchenware and are inhibitory to microbial growth (Aguirre 2022).Through physical and chemical processes known as dissolution and emulsification, the degreasers break down the molecules of grease, fat, oil and mineral deposits and stains.This makes it simpler to remove the residues from kitchen utensil surfaces by rinsing them with water (Georgiana Ileana and Gabriel Lucian 2018; Stratford and Eklund 2003).Also, starchy rice water known as ganji functions as a degreaser (Kora 2020b).The list of various degreasers,  3.

Deodorizers
Peels from a variety of Citrus fruits and seeds of drumstick (Moringa oleifera) are commonly used to clean  and remove odors from kitchen vessels which are used for rinsing, cooking and storing fish, meat and fish-and meat-based curries, respectively (Srinivasan 2019).As the Citrus peels are enriched with flavonoids, saponins, organic acids, antimicrobial essential oils (d-limonene), etc., they aid in degreasing, disinfection of cookware in addition to deodorization and imparting pleasant smell (Kora 2022).Furthermore, a range of materials are utilized to eliminate odors from glass, clay, aluminum, brass, copper and SS kitchen vessels.These materials include crystal salt, wood ash (karra budida), dung ash (kachika), rice bran, sour butter milk, starchy rice water (ganji), fermented idli and dosa batter, etc. (Fig. 7) (Srinivasan 2019).
The soiled and smelly cookware is deodorized using a combination of degreasers (Citrus fruits), plant saponin biosurfactants (Bengal gram), scrubs (coconut coir) and abrasives (ash).For instance, odor from clay cooking pots can be eliminated by combining Citrus peels with Bengal gram seed powder (Eenadu 2023b).

Biosurfactants
For centuries, Indian people utilized plant saponin biosurfactants, which are derived from various parts (leaves, flowers, fruits, fruit pericarp, seeds) of plants that belong to the Sapindaceae (Sapindus sp.) and  saponins and are widely exploited as hair cleanser and dish wash cleaner in rural India (Fig. 10) (Tamilselvi et al. 2018).The peels/pericarps of Citrus sp.fruits and fruits of Indian gooseberry (Phyllanthus emblica) also contain saponins which are also exploited as dish wash cleaners (Fig. 7a-c) (Kora 2022).Plant saponins have many noteworthy properties that make them suitable for use as sustainable dish wash cleaners.These include their natural availability, renewability, low cost, simple extraction, mass production amenability, superior stability at changeable conditions, low critical micellar concentration (CMC) value, biodegradability under aerobic and anaerobic conditions, non-/hypo-human allergenicity, hand biocompatibility, low human and animal toxicity, multifaceted biological activities (antibacterial, antifungal, antioxidant), etc. (Kora 2022;Wisetkomolmat et al. 2021).The saponins show characteristic features of surfactants, including surface tension reduction, foaming, emulsifying and detergent activities.These features enable water to spread and penetrate grease and grime, wet the surfaces, help lift and dissolve dirt and ultimately make rinsing easier (Rungta 2015;Wisetkomolmat et al. 2021;Kora 2022).The list of different traditional saponin biosurfactant cleaners, in terms of their common name, Indian names, scientific name, taxonomic family and source, are given in Table 4.
