Active Ingredient – Sodium Hypochlorite (Environmental)
This ingredient is used as an antimicrobial or disinfectant agent for surface cleaning, water
purification, odour removal and is commonly known as bleach. A research on the adverse
effects on the environment for sodium hypochlorite was done by (Emmanuel et al, 2004). To
prevent the spread of pathogenic microorganisms at the hospital, the waste water was
frequently disinfected using sodium hypochlorite. A toxic environment arises after the
organic matter from the waste water would react readily with the sodium hypochlorite,
forming halogenated organic compounds that affects aquatic organisms.
Active Ingredient- Ethylene glycol (Environmental)
This agent is commonly used in various organic chemicals for cleaning products. It is known
to react with photo-chemical hydroxyl radicals which remains in the atmosphere for a
maximum of two days. It is however non-toxic in the environment as it is readily
biodegradable and does not bioaccumulate in aquatic organisms (Staples et al. 2001).
Active Ingredient- Benzalkonium Chloride (Environmentl)
On two organisms (nematode and zebrafish), the antimicrobials Benzalkonium Chloride
(BAC), Benzalthonium Chloride and chloroxyenol were used to test. On the nematode, BAC
showed comparable toxicity to that of a previously banned antimicrobial TCS on both the
organism and molecular levels. The fish showed a delayed hatching of the egg,
morphological malformation, embryonic toxicity and neurotoxicity of the larvae. The BAC
agent showed acute lethal toxicity in the environment and should therefore be further
examined (Sreevidya et al. 2018).
Active Ingredient- Triclosan (TCS) (Health)
This is agent is commonly used in soaps for both personal care and industrial and is
antibacterial. It has shown evidence of interrupting the endocrine system, affecting the release
of hormones and the various functions such as hormone metabolism from hormone acceptors,
and steroid genic enzyme activity. It is hydrophobic and is has an accumulation potential. It is
suspected to be edc, and have deleterious effects which makes it harmful to humans. The
study is inconclusive and conflicting though it shows some potential that triclosan has
estrogenic effects (Wang, Tian. 2015).
Active Ingredient- Sodium bicarbonate (Health)
A study done by (Kahle et al, 2014) showed that sodium bicarbonate, commonly known as
baking soda, can cause substantial gastrointestinal issues after ingestion. The study’s main
objective was to test the ergogenic effect of sodium bicarbonate after an intense exercise
session Sodium bicarbonate has a large amount of sodium in its composition which can
increase the recommended sodium daily intake past its limits. However, it showed to affect
thirst, bloating, nausea and vomiting in most of the test subjects. This can be especially
severe for individuals with irritable bowel syndrome (IBS).
Active Ingredient- Alkylbenzene sulfonates (Health)
This agent is found in detergents and is an anionic surfactant that is commonly found within
the environment. The human intestinal cell known as Caco-2, showed an increase in cell
proliferation at non cytotoxic concentrations. The elongation factor 2 and dipeptidyl
peptidase 3 were overexpressed and the 14-3-3 protein theta showed a decrease. It was then
deduced that at non cytotoxic concentrations, Alkylbenzene sulfonates can increase growth
rate of the colon cells which can lead to colon cancer as it increases the tumour promotion
effect potential (carcinogenic) (Bradai et al. 2015).
Active Ingredient- Glycerin (health)
This agent is relatively safe agent, as it is naturally occurring in humans, animals and plants
in different forms. It is formed as a by-product from the process of hydrolysis of oils and fats.
Commonly used for cosmetic purposes, Glycerin can be used for hair, oral care and as a
denaturant. It can also be used non cosmetic purposes and can be absorbed rapidly into the
stomach and intestines. When tested on both humans and some animals, it rarely showed
adverse effects except the suppression of spermatogenesis in rats when injected into the testes
(Becker et al. 2019).
Active Ingredient- Aluminium zirconium (Health)
Antiperspirants which is an essential agent for the underarm personal care product to reduce
sweating, consists of aluminium zirconium that serves as its active ingredient. However it is
theorized that this agent is a carcinogen and the source of breast cancer since the breast is
located within close proximity of the underarm. The antiperspirant is frequently applied and
absorbed in the underarm with high concentrations of aluminium zirconium. The element
aluminium is known to alter the DNA and has epigenetic effects therefore can interfere the
oestrogen responsible for breast growth. In the study, MCF cells of the breast are shown to be
disrupted by aluminium for ligand binding and gene expression permitting aluminium to be
an important factor of metals capable of altering oestrogen. An appeal for extensive research
is requested to prove the molecular mechanisms. (Darbre 2005).
Active Ingredient- Hydrogen Peroxide (Health)
Patients that experience tooth sensitivity or cervical root resorption can derive that from that
properties of hydrogen peroxide. This active ingredient is used to clean and disinfect tools,
surfaces as well as bleach the enamel. Hydrogen peroxide has tumour promoting and
genotoxic effects of epithelial and bacterial cells which can affect persons with exposed,
diseased or damaged soft tissues. Blistering and loosening of the skin can occur as a side
effect. It is advised that hydrogen peroxide should be used in moderation and in low doses to
prevent this (Tredwin et al. 2006).
Active Ingredient- Salicylic Acid (Environmental)
This ingredient is commonly used for skin care products, cardiovascular drugs and industrial
dyes. The algal Spirogyra was used to test whether salicylic acid can affect the growth of
algae as it is known that the acid can affect the growth of plants. The cross section of the
algae and its chlorophyll content were analysed, demonstrating growth occurring. Therefore
it can be used to stimulate growth of algae in harsh environments and improve it treatment
probability but can only be accomplished with caution as salicylic acid can cause further
issues such as eutrophication. This is when there is an influx of growth in the algae
population which can block sunlight from reaching below the surface of the water where
aquatic organisms are unable to receive any. This proves that without moderation, salicylic
acid can create environmental pollution (Xu et al. 2020).
Active Ingredient- Sodium lauryl sulphate (Environmental)
The ingredient, Sodium lauryl sulphate, is an anionic surfactant that is used to emulsify in
cleaning products and cosmetics. Amongst the Mytilus galloprovincialis species of mussels,
there has been a decrease in metabolic capacity and respiration rate after it was exposed to
various concentrations of sodium lauryl sulphate. It has also shown decreased limited
antioxidant defence in lower concentrations and cell damage at higher concentrations. This
shows that Sodium lauryl sulphate poses a threat to marine organisms and their physiological
development (Freitas et al. 2020).
Active Ingredient- Sodium Fluoride (environmental)
Sodium fluoride is a common ingredient in toothpastes which aids in the prevention of
cavities in the enamel. There has been little results shown of sodium fluoride causing any
adverse effects in human health but some may have allergic reactions which consists of rash,
swelling of the tongue (“Fluoride (Sodium) Oral: Uses, Side Effects, Interactions, Pictures,
Warnings & Dosing - WebMD” 2021). Though it is unethical to test on animals, mice were
used to test on with small dosages of sodium fluoride and its possible effects on its
reproductive system and fertility. Pregnancy of the mic were significantly reduced after
twelve weeks of the agent was continuously administered to them. It was suggested that the
cause for the reduction stemmed decreased progesterone which lessen the amount of
implantations. Other animals such as owl and foxes also demonstrated a reduction in fertility
rates. This further proves that the high sodium fluoride concentration in drinkable wat can be
linked to a decreased rate of human births (Darmani et al, 2001).
The list of adverse effects obtained for the various active ingredients illustrated that simple
domestic items from every day life can have vast effects on our surroundings and ourselves.
Individuals may use products and be unaware of what exactly they are ingesting or using on
the skin which can lead to complications in their health such as reproductive issues or
gastrointestinal issues. The products that accumulate in soil or water sources can also impact
other living organisms, creating a shift in the ecosystem and further pollution.
