role in maintaining healthy skin. A balanced microbiome acts as a protective barrier, regulates inflammation, and contributes to overall skin wellbeing. As the demand for natural and sustainable
beauty solutions grows, the mānuka leaf extract emerges as a safe, versatile ingredient, combining tradition and modern science to support the health and harmony of the skin, hair and scalp microbiome. Derived from the leaves of the New Zealand endemic mānuka tree, this multitasking extract boasts a unique composition of polyphenols, flavonoids, and essential oils, exhibiting potent antimicrobial and anti-inflammatory activity. By selectively targeting harmful bacteria while preserving beneficial microorganisms, mānuka leaf extract promotes a balanced and resilient skin microbiome. Its applications extend beyond skin care to hair care, contributing to scalp balance and health.
Traditional roots - Māori harvesting practices Māori harvesting practices, deeply rooted in respect for the environment, embrace a holistic approach that goes beyond resource extraction. Guided by principles of traditional harvesting practices - Tikanga, Māori communities prioritize the vitality and longevity of the plant. This is to preserve their natural resources
such a s food and Rongoa – the medicine of the forest for future generations. This unique and sustainable approach is called regenerative harvesting. It includes repurposing of every part of the plant, minimizing waste, and fostering environmental stewardship. By integrating traditional knowledge with modern sustainability principles, the Māori people exemplify a harmonious relationship with the land.
Mānuka leaves - TPT Xtraction® To validate the traditional claims of antimicrobial properties, Organic Bioactives conducted in-depth research using proprietary Tripartite (TPT) Xtraction - green, chemical-free, whole plant extraction technology. Patent pending TPT Xtraction® is a result of
12 years of comprehensive research in highly efficient, chemical free extraction of the whole plant. It implements an innovative three- layered, cold processed, chemical-free bio- liquefication and proprietary filtration system. The main focus is to obtain high yields of
extremely officious cosmetic bioactives with low biomass input, derived from fresh, raw and biodiverse New Zealand land and marine botanicals. This low-speed, cold crushing, and pressing system maximizes the retention of plant vitality, ensuring the release of key bioactives, essential vitamins, antioxidants, enzymes, and minerals. In vitro testing of mānuka leaf extract
demonstrated remarkable antimicrobial activity at varying concentrations (1.5% and 1%). Strains including C. acnes, S. aureus, and C. xerosis, were tested to mimic the sebaceous environment. The results, as depicted in Figure 2, showcase the extract’s ability to combat skin infections, purify acne-prone skin, and protect the skin and hair microbiome.

Mānuka leaf extract and antioxidant properties Expanding on our exploration of mānuka leaf extract’s versatile benefits, we conducted further studies to emphasize its rich antioxidant properties, validating the efficacy of Organic Bioactives’ TPT Xtraction technology in personal care applications. In a comprehensive evaluation, we
subjected the mānuka leaf extract to various antioxidant assays, highlighting its potential as a natural alternative for cosmetic formulations. Our first examination involved assessing the
antioxidant activity of the mānuka leaf extract against vitamin C (ascorbic acid) through the Trolox equivalent antioxidant capacity (TEAC) assay. Utilizing a spectrometer, we compared the sample to known concentrations of Trolox standards. Remarkably, at a concentration of only 2%,
the mānuka leaf extract exhibited more than double the total antioxidant capacity compared to conventional vitamin C at a significantly higher concentration (15% w/v). In our second analysis, we employed the
CUPRAC (cupric reducing antioxidant capacity) assay to determine the total polyphenol concentration equivalent to gallic acid. By mixing the mānuka extract with the CUPRAC reagent and measuring absorbance at 450nm after 30 minutes, we established a total polyphenol concentration equivalent to 67.2ug/ ml gallic acid.
The findings underscore the mānuka leaf
extract’s promise as a potent antioxidant in cosmetic formulations, emphasizing its superiority even at lower concentrations compared to traditional alternatives. Beyond antioxidant capabilities, our
investigation extended to measuring the mānuka leaf extract’s relative chelating properties against the industry-standard EDTA at equivalent concentrations. Impressively, the mānuka leaf extract exhibited a relative metal chelating property of 76.8%, suggesting its potential as a natural booster for existing formulations requiring chelating agents. In conclusion, our research showcases
the mānuka leaf extract as a multifaceted ingredient, not only promoting skin, scalp, and hair health but also offering a sustainable and effective alternative in the realm of antioxidants, anti-microbial, and chelating agents for cosmetic formulations. Organic Bioactives invites the beauty industry to explore the vast potential of the mānuka leaf extract in creating innovative, nature-inspired skin care, scalp care and hair care products.
Mānuka leaves - unveiling nature’s power for hair and scalp wellness The field of scalp health and hair care has been evolving, with ongoing research and advancements. Increased awareness of hair and scalp health
has led to a growing demand for effective and accessible cosmetic ingredients that do not disturb sensitive scalp biome and negatively affect hair follicles. Since Covid, several trends are shaping
the hair and scalp product market. Consumer preferences in this industry tend to evolve based on factors such as lifestyle changes, technological advancements, and a growing emphasis on natural and sustainable ingredients. Consumers are increasingly seeking products
with clean and minimal ingredient lists, avoiding harsh chemicals such as sulphates, parabens, and silicones. Sustainable packaging and environmentally friendly practices are also gaining importance. There is a growing demand for hair and
scalp products containing natural and organic ingredients. Botanical extracts, essential oils, and plant-based formulations are popular choices as consumers prioritize clean and green beauty. Hair and scalp products are incorporating
wellness-oriented ingredients such as adaptogens, vitamins, potent antioxidants, and minerals to promote overall hair and scalp health. Products that align with broader wellness trends, supporting stress and ROS reduction and relaxation, are also gaining traction.
