Ingredients to Avoid in your Deodorant
when you're Pregnant

Congratulations. Having a baby is such an exciting time. Suddenly, you start to notice prams and buggies everywhere. And you find yourself paying attention to what you're putting in and on your body. 

With Ultrella I was determined to create a deodorant using natural ingredients that was just as effective as a synthetic one, because there are certain times in life when you really need natural products but you also need them to work.  It was important that our customers could have access to natural, effective but most importantly safe solutions for them to use during this incredible journey .

Why? Well having delivered three pretty awesome kids, I understand that when you're pregnant, you need to have the safest options possible both during and after your pregnancy. 

That's why you will never find the following ingredients in our products.... 

Aluminium or Aluminum

Aluminium Compounds and/or Aluminium Salts are a key ingredient in most antiperspirant products.When they come in contact with moisture on the skin, they dissolve to form a gel. This gel creates a temporary barrier over the sweat glands, meaning sweat doesn’t reach the skin’s surface. They stop sweating that’s for certain, but FYI they’re also responsible for the big yellow stains you get on your tops.

Also, there are a number of studies out there linking use of aluminium to breast cancer and Alzheimer's. I’m the first to put my hand up and say I don’t have a medical background, so I would encourage you to do your own research and reach your own conclusions.

The thing is, our bodies were designed to sweat and this can increase during pregnancy due to our increased blood volume and changes in metabolism.

Sweating is fine, in fact it's more than fine. It's essential. It’s how we control our temperature when we’re hot or when we’re exercising and also how our body reacts when we're stressed or nervous.

If you’re using an antiperspirant daily, then how is your body going to perform this vital task?  


Methylparaben, Ethylparaben, Butylparaben- Our advice would be to basically steer clear of any product that ends with paraben. Parabens are preservatives that are commonly used in body care products and they are known endocrine disruptors.

FYI - the endocrine system is the control centre for your body’s hormone production and no one wants to go messing with it when there's a developing baby on board.

Propylene Glycol

Propylene Glycol is the base for many deodorant products because it creates a smooth consistency. It is commonly produced from petroleum, but can also be derived from natural gas or vegetable sources. It is a key ingredient in antifreeze products for cars and airplanes. It acts as a penetration enhancer. This means that if it is paired with harmful chemicals, it can increase their absorption rates.

Also, PG is a known skin irritant, with links to allergic reactions in the skin. Examples include contact dermatitis and non-immunologic contact urticaria (commonly known as hives). Ouch! 

Propylene Glycol is also used in antifreeze for your car!!


Triclosan is an antimicrobial agent that is commonly used in antiperspirants and deodorants – even supposedly 'natural' ones. It was initially developed as a surgical scrub for medical professionals, but is used in bodycare products to kill bacteria and fungus and prevent odours. 


Phthalates are plasticising chemicals that are often used in deodorants to improve the consistency of the product. They also help to dissolve other ingredients. They are known to be endocrine disruptors that may wreak havoc with your hormonal function. They have also been linked to a range of other serious complications such as infertility and low sperm count, cancer, organ damage and endometriosis

Baking Soda 

And finally, Baking Soda. Baking Soda, or Bicarbonate of Soda, isn’t as controversial as the ingredients above, but you still won’t see it on our ingredient lists. Baking Soda is a really effective deodoriser but it’s also really harsh on the skin because it’s super alkaline. Just think back to making volcanoes at school with vinegar and baking soda. This mini reaction happens every time it’s applied to the skin. Your skin’s protective layer is called the Acid Mantle. Over time, products containing Baking soda react with the Acid Mantle and start to wear it away. Our theory is that that’s why lots of people are okay with a BS based deodorant for a week or two, but then they start to react.  

Why not save your Baking Soda for the kitchen and, when they're big enough, the kids’ smelly sports shoes?!

Save your baking soda for your kitchen

Please do your own research and reach your own conclusions, however having been pregnant three times I can speak from experience when it comes to comfort, peace of mind and being more conscious of what I was using.

If you’re keen to dig deeper and do your own research, then here's a great place to start:
