Why we’re proud of the Petrichor formula
Ingredients that work
Ingredient fear is real. Questioning what’s actually in the products that go onto your skin is important. After all, it is your biggest organ and the one that’s most exposed to the outside world. But the great product paradox is that ‘clean’ doesn’t always mean credible, and safe ingredients that truly work are often unjustly left out. It’s why we believe in transparency – about our products, their clinical backing and why we’re proud to include them. Knowing what to look out for on the back of a bottle is powerful – you know what you're choosing and why you’re choosing it. Fear free.
The science-backed standouts
Aluminum ZIrconium Tetrachlorohydrex Gly
The ingredient that dominates the Sweat Care conversation. It works by forming a temporary gel plug in the eccrine sweat ducts, reducing sweat output at the source. It dissolves and clears naturally. An effect currently unmatched by any plant-based alternative.
It's well understood, tightly regulated and has been used for decades with a strong safety record. So for us, it’s a deliberate choice for people who want real sweat control, not just odour cover-up.
Fear around aluminium has been largely fuelled by marketing, not science. We’re guided by research from Cancer Council and PubMed that show no conclusive link between the use of aluminium-containing products and an increased risk of negative health outcomes.
In fact, more aluminium is consumed daily from food than deodorants. Not a scary statistic, but one that shows how little aluminium exposure anti-sweat products actually give.
Salicylic acid
Sounds clinical. But it’s actually one of the most-well understood, skin-friendly ingredients. Derived from willow bark, salicylic acid is known in skincare as an exfoliant. And in Sweat Care, it’s a strategic player that gently encourages the turnover of skin cells – keeping pores clear and reducing buildup that would otherwise allow odour-causing bacteria to thrive.
Effective without being harsh, this widely studied ingredient is especially powerful when it comes to areas like underarms – where it’s able to penetrate pores rather than sitting on the surface. In our products, it’s an intentional choice to support active lifestyles.
Triethyl citrate
Lesser known, but no less important. This smart addition to our formulas targets the chemistry of odour itself, by preventing the bacterial enzymes that turn apocrine sweat into odour. No aggressive antimicrobials (sterile is never the goal) – a scientific interruption of the sweat-to-smell process.
The sweat support system.
These star players don’t work alone. The inclusion of stabilisers, emollients, and skin-conditioning agents is the difference between an ingredients list and an effective Sweat Care formula. Adding in ethylhexylglycerin, niacinamide + panthenol and urea means the actives can do their work without irritating or overwhelming the skin. So you can use them to your advantage, without worry of side effects.
The influence of ‘clean beauty’.
With a strong movement towards clean skin and Sweat Care, there has been great change in how we as consumers consider what’s in the products we use. A positive and necessary shift in awareness.
But this shift has also led to broad, generalised ingredient fear that doesn’t take concentration and context into consideration. We believe that not everything needs to be excluded, but everything does need to be justified. It’s why we’re transparent about what we use, why we’ve chosen it and how it will help active people manage sweat. That way – you get to decide.
Anti-sweat meets pro-skin.
Among the active ingredients, we include extras that support your skin microbiome. Rhamnose, glucose and glucuronic acid are present across the entire Petrichor range, supporting hydration and a healthy skin barrier.
This trio does things selectively and prebiotically. It supports beneficial bacteria while disrupting the metabolic pathways of the odour-causing ones – a fundamentally smarter approach compared to many products that wipe out the entire ecosystem with overly harsh formulas.
Our goal is to create a balanced skin environment, not a sterile one, where Sweat Care can be most effective. You don’t have to choose between handling sweat and supporting skin – with the right ingredients and a smart formula, you can have both.
