Mrs. Meyer’s Basil Dish Soap

This plant-derived, grease-cutting dish soap blends potent foaming surfactants with botanical essential oils and skin-soothing glycerin for an aromatic and thorough clean.

Performance Rating: 8.0

The formula demonstrates strong grease-cutting capabilities driven primarily by Sodium Lauryl Sulfate, a potent anionic surfactant known for rapid soil removal and abundant lathering. This primary cleaner is effectively supported by a secondary surfactant blend of Lauramine Oxide, Lauryl Glucoside, and Caprylyl/Capryl Glucoside, which significantly boosts foam stability and helps emulsify stubborn oils and food residues. Additionally, Sodium Chloride works as a viscosity builder to provide an optimal texture, while Citric Acid stabilizes the pH balance to ensure consistent cleaning action, yielding a thoroughly reliable and high-performing dishwashing detergent.

Safety Rating: 5.4

The moderate safety assessment reflects a trade-off between skin-conditioning additives and potential irritants. While soothing agents like Aloe Barbadensis Leaf Juice and Glycerin help mitigate dryness, Sodium Lauryl Sulfate is a known skin irritant that can strip natural skin lipids. Furthermore, the presence of added fragrance, along with specific allergens like Geraniol and Linalool, presents risks of contact dermatitis. Most notably, the inclusion of the synthetic preservatives Methylisothiazolinone and Benzisothiazolinone introduces recognized skin sensitizers, which notably impacts the formulation’s safety and mildness for individuals with reactive or sensitive skin.

Final Rating: 6.8

The overall assessment reflects a functional dish soap that balances robust cleaning efficacy with a moderate ingredient hazard profile. On one hand, the synergy between anionic and non-ionic surfactants delivers exceptional grease-cutting power, reliable sudsing, and smooth product dispensation. On the other hand, the formulation’s mildness is noticeably compromised by the inclusion of isothiazolinone preservatives, strong degreasers, and fragrance allergens. Ultimately, the product serves as a capable, conventional household cleaner that excels in everyday dishwashing tasks while posing potential irritation risks for users with sensitive or allergy-prone hands.

Verdict

The cleaning foundation of this formula relies on an effective blend of Sodium Lauryl Sulfate (SLS) and milder co-surfactants such as Caprylyl/Capryl Glucoside, Lauryl Glucoside, and Lauramine Oxide. This combination delivers exceptional grease-cutting power and generates rich, persistent suds capable of lifting baked-on food residues and heavy cooking oils effortlessly. While SLS is known to be an intensive cleanser, balancing it with non-ionic glucosides helps moderate potential harshness on the skin without sacrificing cleansing efficacy, making it well-suited for daily pots, pans, and tableware.

To support hand comfort during repeated washing, the formula incorporates glycerin and Aloe Barbadensis Leaf Juice, which act as soothing humectants to attract and retain moisture. These additions help mitigate the moisture-stripping effects of high-foaming surfactants on the skin barrier. The addition of citric acid ensures an optimal pH balance, while sodium chloride serves as a natural thickening agent for smooth dispensing. As a result, the dish soap rinses away cleanly without leaving persistent filmy residues on glassware, ceramic, or stainless steel cookware.

A distinct highlight is the inclusion of botanical essential oils, specifically Basil Oil, Parsley Seed Oil, and Black Pepper Seed Oil, paired with fragrance compounds like Geraniol and Linalool. These ingredients provide an invigorating herbal scent profile that transforms routine dishwashing into a pleasant sensory experience. However, natural and synthetic fragrance components can sometimes present a challenge for individuals prone to contact allergies, as botanical oils naturally contain aromatic compounds that may trigger sensitivities in reactive individuals.

From a stability standpoint, preservation is handled by Benzisothiazolinone and Methylisothiazolinone (MIT), which provide robust antimicrobial protection against bacteria, yeast, and mold contamination over time. While isothiazolinones are recognized skin sensitizers for a subset of the population, their presence in rinse-off household detergents remains within standard regulatory safety thresholds. Overall, this dish soap represents a well-balanced, high-performance cleanser that excels at cutting through stubborn kitchen grease while offering a refreshing garden-fresh aroma.
