Member’s Mark Triple Butter Body Wash

A deeply moisturizing body wash rich in Soybean Oil and Shea Butter that offers a creamy lather, though it relies on Sulfates and strong preservatives.

Performance Rating: 4.3

This body wash offers excellent moisturizing capabilities combined with effective cleansing. The inclusion of Sodium Laureth Sulfate ensures a rich lather, while the high ranking of Glycine Soja (Soybean) Oil indicates a significant lipid deposit to combat dryness. The formula is enriched with luxury emollients like Shea Butter, Cocoa Butter, and Sweet Almond Oil, alongside mild amino-acid based surfactants like Sodium Cocoyl Glycinate and Sodium Lauroyl Isethionate. This combination results in a creamy texture that leaves skin feeling soft and conditioned rather than stripped.

Safety Rating: 3.1

While effective, the safety profile is lowered by the presence of Methylchloroisothiazolinone and Methylisothiazolinone. These preservatives, often called the ‘Itchy Ms’, are known contact allergens and can cause dermatitis in sensitive individuals. Additionally, Sodium Laureth Sulfate can be drying for some, although it is well-buffered here by oils. The inclusion of unspecified Fragrance is also a potential trigger for those with sensitivities.

Final Rating: 3.7

Overall, this is a high-performing mass-market body wash designed for dry skin. It excels at balancing deep cleansing with skin nourishment thanks to its rich blend of fatty acids and botanical oils. However, the use of sensitizing preservatives prevents it from achieving a top-tier rating, as better, gentler alternatives are available in modern formulations. It is an excellent choice for normal to dry skin types that are not allergic to isothiazolinones.

Verdict

This body wash presents a complex formulation that balances highly nourishing ingredients with strong industrial cleansers and preservatives. At its core, the product is designed to combat dryness. The inclusion of Glycine Soja (Soybean) Oil as the third ingredient is a standout feature. Unlike many standard washes that rely solely on water and detergents, this high oil content suggests a formula that feels rich, velvety, and replenishing on the skin. This lipid-rich base is further enhanced by a robust blend of premium butters, including Theobroma Cacao (Cocoa) Seed Butter, Butyrospermum Parkii (Shea) Butter, and Simmondsia Chinensis (Jojoba) Butter. These emollients are excellent for repairing the skin barrier and smoothing out rough patches.

To balance these heavy oils, the product uses Sodium Laureth Sulfate (SLES) as the primary surfactant. While sulfates are often criticized for stripping natural oils, their presence here is functional; they provide the necessary lifting power to wash away the heavy vegetable oils in the formula so you are not left feeling greasy. The combination of SLES with Sodium Lauroamphoacetate and Sodium Cocoyl Glycinate likely results in a very dense, luxurious foam that feels substantial rather than airy. The addition of Glycerin and Beta-Glucan adds a humectant layer, drawing water into the skin to complement the occlusive nature of the oils.

However, the product’s preservation system prevents it from being a universal recommendation. The formula utilizes Methylchloroisothiazolinone and Methylisothiazolinone. Often colloquially known as the “Itchy Ms,” these are potent biocides that have high rates of contact allergy. For the average user with resilient skin, they are effective preservatives, but for anyone with a history of dermatitis, they are best avoided. Additionally, the presence of Fragrance without specific component listing implies a synthetic blend that could further irritate sensitive noses or skin types.

In conclusion, this product acts as a heavy-duty moisturizer disguised as a daily cleanser. It is an excellent choice for individuals with dry, winter-parched skin who do not have specific chemical sensitivities. The moisture-deposit effect implied by the oils will leave skin feeling soft and conditioned. However, if you are prone to eczema, allergic reactions, or prefer clean beauty standards that exclude sulfates and strong sensitizers, this formulation is likely too harsh despite its botanical claims.
