Quick Summary

Melaleuca's Ingredient Philosophy: A Balanced Approach

Melaleuca, often known as 'The Wellness Company,' builds its product lines on a philosophy that prioritizes a balance of natural ingredients with proven scientific formulations. The company's in-house team of scientists develops and tests these formulas to ensure efficacy and safety. While the core mission emphasizes naturally-based components, Melaleuca acknowledges that some man-made organic compounds are occasionally more effective or safer than volatile natural alternatives, and are used when deemed necessary.

Core Ingredients Across Product Categories

Across its diverse range of products, Melaleuca frequently relies on several key ingredients, highlighting their natural origins and functions:

Melaleuca Oil: Sourced from the Melaleuca alternifolia plant in Australia, this namesake ingredient is used in many cleaning and personal care products for its antimicrobial and stain-fighting properties.
Citric Acid: A natural acid derived from citrus fruits, citric acid is a central component in many of Melaleuca’s cleaners. It effectively dissolves mineral deposits and soap scum and serves as a biodegradable alternative to harsh chemicals like chlorine bleach.
Thyme Oil: This natural essential oil is included in botanical disinfectants, where it is leveraged for its ability to kill bacteria and viruses.
Glycolic Acid: Found naturally in sugar beets, glycolic acid is another safe and effective cleaning agent used to combat hard water and soap scum.
Glycerin: A common moisturizing ingredient, glycerin is used extensively in personal care products and is a skin-identical humectant.
Essential Oils: Beyond Melaleuca and thyme oils, a variety of other naturally sourced essential oils are blended into products for fragrance and additional benefits.

Melaleuca's 'No' List and Safety Standards

In addition to promoting its 'ingredients you can love,' Melaleuca maintains a stringent 'ingredients we don't use' list, avoiding a host of common, potentially harmful chemicals found in mainstream products. This list includes:

Chlorine Bleach: Avoided due to its corrosive and potentially dangerous nature.
Ammonia: Excluded for its irritating and corrosive properties.
Formaldehyde: A known allergen and carcinogen that Melaleuca pledges to never use.
Parabens: Chemical preservatives known to disrupt hormone function, which are not used in Melaleuca's formulations.
Phthalates: Links to health concerns such as asthma and hormone disruption lead to their exclusion.
Triclosan: Avoided due to its connection with antibiotic resistance.
Phosphates: Not used in cleaning products to prevent harm to aquatic ecosystems.
