EVALUATING ANTIMICROBIAL ACTION OF MACADAMIA, FLAXSEED GENTLE AND HERBAL PROTEX SOAPS.
ABSTRACT:
This experiment investigated the antibacterial efficacy of three Protex soap variants—Macadamia, Gentle with Flaxseed Oil, and Herbal—against Staphylococcus aureus and Escherichia coli using the Kirby-Bauer disk diffusion method. Zones of inhibition were measured to assess antibacterial effectiveness. Protex Herbal exhibited the greatest antibacterial activity against both bacterial strains, followed by Macadamia and Gentle with Flaxseed Oil. Results suggest formulation differences significantly impact antibacterial potential.
INTRODUCTION:
Plant-derived products have long been utilized in skincare and pharmaceutical applications for their antimicrobial properties. Among these, honey, flaxseed oil, and herbal extracts are widely known for their ability to inhibit microbial growth due to bioactive compounds like flavonoids, phenolics, and essential oils (Mandal & Mandal, 2011; Cui et al., 2018). The increasing interest in natural antimicrobial agents is driven by concerns over antibiotic resistance and a demand for safer, eco-friendly alternatives. Antibacterial soaps are formulated to reduce or eliminate bacteria on the skin, playing a crucial role in infection control. Protex, a widely available brand, claims to provide antibacterial protection through various natural ingredients. This study evaluates the antibacterial activity of three Protex variants—Macadamia, Gentle with Flaxseed Oil, and Herbal—against Gram-positive Staphylococcus aureus and Gram-negative Escherichia coli.
The Kirby-Bauer disk diffusion method is a standardized technique used to assess the susceptibility of bacteria to antimicrobial substances. This method enables researchers to evaluate the antibacterial potential of natural products by measuring the zones of inhibition around impregnated disks (Bauer et al., 1966).This study aims to evaluate and compare the antibacterial efficacy of three Protex soap products—Macadamia, Gentle (with Flaxseed Oil), and Herbal (with mixed extracts)—against selected bacterial strains using the Kirby-Bauer method. The Kirby-Bauer disk diffusion method is a standard antimicrobial susceptibility test that allows visual assessment of bacterial growth inhibition by an agent (Bauer et al., 1966). Differences in bacterial cell wall structures between Gram-positive and Gram-negative species influence susceptibility to antimicrobial agents (Prescott et al., 2002).
Protex is a globally marketed soap brand that offers several variants with different natural additives claimed to have antibacterial effects. The Herbal variant often includes ingredients like thyme or tea tree oil; the Macadamia variant is promoted for its content of methylglyoxal, a compound with known antibacterial action; and the Gentle variant, containing flaxseed oil, is marketed for sensitive skin but not primarily for its antibacterial properties. By comparing the antibacterial effectiveness of these variants, this study seeks to validate or challenge these commercial claims using microbiological methods.

LITERATURE REVIEW:
Plant-derived products have gained significant attention in recent years due to increasing concerns over antimicrobial resistance and consumer preference for natural alternatives in personal care products. Soaps infused with botanical ingredients such as honey, flaxseed oil, and various herbal extracts have been extensively researched for their potential to combat microbial infections (Al-Waili et al., 2011; Mandal & Mandal, 2011).
Manuka honey, a monofloral honey derived from the Leptospermum scoparium plant in New Zealand, is well known for its powerful antibacterial properties. The primary compound responsible for this effect is methylglyoxal (MGO), which is present in high concentrations in Manuka honey. MGO, along with hydrogen peroxide and low pH, contributes to its effectiveness against both gram-positive and gram-negative bacteria (Mandal & Mandal, 2011). In vitro studies have demonstrated its inhibitory action on Staphylococcus aureus and Pseudomonas aeruginosa, among others.
The flaxseed oil, extracted from the seeds of Linum usitatissimum, is another plant-derived substance with antimicrobial potential. It contains alpha-linolenic acid, a type of omega-3 fatty acid, and lignans, which exhibit antioxidant and antibacterial properties (Cui et al., 2018). Cui and colleagues reported the bacteriostatic effects of flaxseed oil against foodborne pathogens such as Escherichia coli and Listeria monocytogenes. The mechanism of action is thought to involve disruption of bacterial cell membranes and oxidative stress induction.
Herbal extracts, including essential oils from thyme, rosemary, chamomile, and eucalyptus, are also widely studied for their antibacterial activity. These plants contain various bioactive compounds such as thymol, eugenol, and carvacrol, which can permeate bacterial membranes, leading to leakage of cellular contents and eventual cell death (Burt, 2004). For instance, thyme and chamomile extracts have been proven to inhibit a broad spectrum of bacteria and fungi, supporting their inclusion in antimicrobial formulations (Saeed et al., 2019).
Several studies have compared the efficacy of plant-based soaps to conventional antibacterial agents. Al-Waili et al. (2011) showed that honey-based soap formulations exhibited comparable, if not superior, antibacterial effects to commercially available triclosan-based soaps. Moreover, plant-derived soaps are often associated with fewer side effects and reduced risk of developing resistant bacterial strains.
In conclusion, the existing literature strongly supports the antimicrobial potential of Manuka honey, flaxseed oil, and herbal extracts. These natural ingredients act through a variety of mechanisms, including oxidative damage, enzyme inhibition, and membrane disruption. Their inclusion in Protex soap variants suggests a promising alternative to synthetic antimicrobial agents in personal hygiene products.
AIM:
The aim of this experiment was conducted to determine and compare the antibacterial efficacy of three Protex soap variants (Macadamia, Gentle with Flaxseed Oil, and Herbal) against S. aureus and E. coli by using the Kirby-Bauer disk diffusion method.
OBJECTIVES:
To evaluate the antibacterial effectiveness of three Protex soap variants (Herbal, Macadamia, and Gentle with Flaxseed Oil) using the Kirby-Bauer disk diffusion method.
To compare the zone of inhibition produced by each soap variant against Staphylococcus aureus and Escherichia coli.
To determine which Protex soap variant demonstrates the highest antibacterial activity.
RESEARCH QUESTIONS:
Which Protex soap variant exhibits the highest antibacterial activity against Staphylococcus aureus and Escherichia coli?
How do the antibacterial effects of the Protex soap variants differ between Gram-positive and Gram-negative bacteria?
Does the presence of specific natural ingredients (e.g., Manuka honey, herbal extracts, and flaxseed oil) correlate with higher antibacterial efficacy in Protex soaps?
HYPOTHESES:
Null Hypothesis (H₀): There is no significant difference in antibacterial activity among the three Protex soap variants.
Alternative Hypothesis (H₁): At least one Protex soap variant shows significantly higher antibacterial activity than the others.
MATERIALS USED:
The materials used in this experiment included three types of Protex soaps: Protex Macadamia, Protex Gentle, and Protex Herbal. Mueller-Hinton agar plates were prepared as the culture medium. Sterile cotton swabs were used to inoculate the plates with bacterial cultures. The bacterial strains used were Staphylococcus aureus and Escherichia coli. Sterile forceps were utilized to handle the filter paper disks, which had been soaked with the soap solutions. Distilled water and chloropenol were used for control. An incubator set at 37°C was used to incubate the plates. A ruler or caliper was employed to measure the zones of inhibition around the disks. Additionally, sterile water and soap solutions prepared from the three soaps were used in the experimental procedure.
METHODOLOGY USED:
The experiment was begun with the preparation of nutrient agar plates. Each plate was divided into five equal sections using a marker on the bottom, and labeled with the initials of the soap types including two controls: P1 for Herbal, P2 for Gentle, P3, and + (ve) for Chloropenol and – (ve) for distilled water (controls).The bacterial cultures were obtained from the test tubes, and sterile cotton swabs were used to inoculate the surface of the agar evenly, ensuring a uniform bacterial lawn. Soap solutions were prepared by dissolving each type of soap in sterile water. Sterile paper disks were then soaked in the soap solutions. Using sterile forceps, one soaked disk of each soap was placed into its respective section on the agar plate. The plates were incubated at 37°C for first 24 hours, 48 hours and 72 hours (3 days observation being done). After incubation, zones of inhibition were observed around each disk, measured with a ruler, and recorded to compare the antibacterial efficacy of the three Protex soaps.

### DISCUSSION OF THE RESULTS:
The results of the antibacterial tests conducted using the Kirby-Bauer disk diffusion method indicated clear differences in antibacterial efficacy among the three variants of Protex soap against both **Staphylococcus aureus** and **Escherichia coli**. On day 1 of observation, the largest zones of inhibition were measured for Protex Herbal (P1) and Protex Macadamia (P2) with values of 1.2 cm and 1.5 cm, respectively, while Protex Gentle with Flaxseed Oil (P3) had the smallest zone of inhibition at 1.2 cm (Table of Results). Interestingly, while the zone of inhibition for the herbal variant diminished over the subsequent days, the Gentle variant’s effectiveness increased slightly by the third day, suggesting a delayed or reduced action of the gentler formulation (See Table of Results).
The finding that Protex Herbal exhibited the highest antibacterial activity aligns with previous studies that highlighted the antimicrobial properties of herbal components, such as essential oils (Burt, 2004; Saeed et al., 2019). Flavonoids, phenolics, and other bioactive compounds present in herbal extracts can permeate bacterial membranes, leading to cell lysis and death (Burt, 2004).
Conversely, the second variant, Protex Macadamia (which may provide some antibacterial effects because of the presence of methylglyoxal, a known antibacterial agent found in Manuka honey), while effective, did not outperform the herbal variant (Mandal & Mandal, 2011). This suggests that the blend of herbal ingredients in Protex Herbal synergistically enhances antibacterial potency more effectively than the constituents in the Macadamia variant.
Protex Gentle with Flaxseed Oil exhibited the lowest overall antibacterial efficacy throughout the tested periods. This may be attributable to its formulation focusing more on being sensitive to skin rather than maximizing antibacterial effects. Though flaxseed oil is known for its anti-inflammatory and moisturizing properties (Cui et al., 2018), its effectiveness against bacterial agents appears limited when compared to other more concentrated natural antimicrobial agents.
In terms of Gram-positive versus Gram-negative effectiveness, it is notable that all soap variants showed generally greater efficacy against **Staphylococcus aureus** (Gram-positive) compared to **Escherichia coli** (Gram-negative). The structural differences in bacterial cell walls contribute to this phenomenon; the thicker peptidoglycan layer in Gram-positive bacteria can make them more susceptible to certain antimicrobial agents than Gram-negative bacteria, which possess an outer membrane that can limit penetration of such agents (Prescott et al., 2002).
### CONCLUSION:
This study successfully demonstrated that the antibacterial efficacy of Protex soaps varies significantly based on their formulations. Protex Herbal exhibited the highest activity against both tested bacterial strains, followed by Protex Macadamia, while Protex Gentle with Flaxseed Oil showed the least effectiveness. As the demand for natural products increases, these findings support the development and use of more herbal-infused antibacterial formulations as a safer alternative to synthetic agents.
### RECOMMENDATIONS:
1. **Further Research**: Conduct additional studies comparing a wider range of natural antibacterial soaps, including those with varying concentrations of active ingredients to better understand the relationship between formulation and antibacterial efficacy.
2. **Long-term Retail Evaluation**: Investigate whether the antibacterial effectiveness persists when exposed to environmental conditions, such as varying temperatures or humidity levels, commonly encountered in homes.
3. **Consumer Awareness**: Educate consumers about the efficacy differences between various soaps and highlight the potential benefits of herbal ingredients in personal hygiene products.
4. **Quality Control**: Manufacturers should ensure consistent formulation standards to maintain expected antibacterial properties across different batches of soap.
