However, the only challenge in developing countries is the availability of cosmetics that do not meet quality standards, which can pose health risks to users. Upon this study, lipstick samples were found to have high concentration of heavy metals, which are copper (Cu), Arsenic (As), Tellurium (Te), Niobium (Nb), Antimony (Sb), and Lead (Pb) at 50.0 ppm, 2.0 ppm, 48.0 ppm, 30.0 ppm, 25.0 ppm, and 7.0 ppm respectively. With respect to toothpastes, three metals that were found in significant amounts are Cu at 10.0 ppm, Te at 31.0 ppm and Ta at 12.0 ppm. The level of Antimony (Sb) in lipsticks was found to be higher than the limit set by World Health Organization (WHO). This can lead to problems such as skin disease, hormonal disorders, and even cancer. Due to this situation, there is a need to strengthen regulation and monitoring of cosmetic quality in the market, as well as to educate consumers on the importance of choosing safe products for their health. Additionally, cosmetic manufactures should adhere to international standards to protect the health of consumers.

Typical waxes, such as beeswax, carnauba wax, and candelilla wax, give the lipstick its structure and firmness [38]. Oils like castor oil, lanolin, and mineral oil ensure smoothness and even application [14]. Emollients such as shea butter and vitamin E are included to moisturize and protect the lips [40]. Other pigments, which include a range of natural and synthetic dyes, give lipstick its color. Furthermore, lipsticks and toothpaste are cosmetics intended for application in the oral area, including on the mouth parts, specifically on lips and teeth [15]. Toothpaste typically contains a combination of abrasives, fluoride, flavoring agents, and other ingredients that aid in cleaning, polishing, and freshening breath [34]. Although toothpaste is mainly used for oral hygiene, it also improves the appearance of teeth and contributes to a bright, healthy smile. Lipstick is a popular cosmetic product used to improve the color, texture, and overall look of the lips [17]. It plays a key role in facial aesthetics and carries cultural, psychological, and economic importance. Examples of lipsticks are Matte Lipsticks, Satin and Cream Lipsticks, Gloss Lipsticks, and Liquid Lipsticks [33]. Toothpaste is a gel or paste used in combination with a toothbrush to clean and maintain the health of teeth [26]. Its primary functions are to remove plaque, prevent tooth decay, and reduce gum disease [20]. As toothpaste is used by both adults and children. Reports show that children and some adults (pregnant women especially), swallow a substantial amount of 5 toothpaste in the process of brushing, which could lead to any of the effects associated to the ingestion of these substances [16]. Heavy metals are metallic elements with high atomic weights and densities that are oſten toxic at relatively low concentrations [2]. ey occur naturally in the environment and can also be introduced through industrial processes, agriculture, and pollution [1]. Some heavy metals are essential for biological functions in trace amounts, but excess exposure can lead to serious health problems [21]. e presence of heavy metals in lipsticks and toothpastes is a significant concern due to their potential health risks [9]. Heavy metals found in lipsticks and toothpastes may include lead, cadmium, mercury, and chromium. ese metals can be present as contaminants in pigments used for coloring or as impurities in raw materials [23]. Even small amounts of lead can accumulate in the body over time and potentially result in neurological and developmental issues, particularly in children and pregnant women [35]. Exposure to cadmium is associated with kidney damage, bone loss, and cancer [8]. Mercury also can affect the kidneys, nervous system, and immune system, and is particularly harmful when absorbed through the skin or ingested [41]. Zanzibar has emerged as a significant market for cosmetics, with numerous products imported from various countries. e
