The Hidden Truth About "All Mineral-100% Mineral" Sunscreens - THEY ARE CHEMICALS!

100% mineral!! Chemical-free, I'm so tired of these lies.

As the Sunscreen Evangelist, I have been manufacturing, marketing, and educating people on sun safety and sun awareness for over 30 years. From day one, I have told people the truth about sunscreen. All sunscreens are chemicals, period. The worst part is that I'm so tired of all the MIS-INFORMATION and marketing BS from competitors and watchdog groups.

When you pick up a sunscreen labeled "mineral," you expect pure, natural protection from the sun. But look beyond the active ingredients and marketing, as a sneaky ingredient lurks in many of these sunscreens, blurring the lines between mineral and chemical. 

Meet Butyloctyl salicylate – the hidden player in the sunscreen game. Let's unravel the truth behind this ingredient and what it means for your skin's safety.

What is Butyloctyl Salicylate (BOS)?

Butyloctyl salicylate is a synthetic ester derived from Salicylic Acid and Butyl Octanol. It's in a lot, over 300 sunscreens, and it's a modified version of Ethylhexyl Salicylate, also known as Octisalate, a chemical sunscreen ingredient. So, why is it in your "all mineral" sunscreen, and is it safe?

WHY use Butyloctyl Salicylate in Mineral Sunscreens: A Game Changer?

1. Superior Spreadability: This ingredient is a master of disguise, ensuring your sunscreen glides smoothly and evenly. No more white streaks or patchy coverage!

2. Enhanced UV Filter Performance: Butyloctyl salicylate boosts the solubility and stability of UV filters, making your sunscreen more effective at shielding you from harmful rays. Because it's a UV filter itself?

3. Luxurious Texture: Say goodbye to greasy, heavy sunscreens. This ingredient gives mineral sunscreens a lightweight, silky feel that makes application a breeze.

4. Long-Lasting Protection: It helps your sunscreen stick to your skin, offering prolonged protection even during intense sun exposure.

Is Butyloctyl Salicylate Safe? The Controversy Unveiled!

The safety of Butyloctyl salicylate has been a hot topic. It is a "chemical" UV filter, yet for some unknown reason, Health Canada and the FDA have not regulated it. Hence, it's not listed as an active ingredient but as an inactive ingredient.

This issue is not that these ingredients are not safe, but rather that the consumer is being misled into believing they are getting a 100% Mineral sunscreen when, in reality, they are also getting chemical UV filters.

The manufacturers that market "natural brands" and the watchdog groups such as EWG, Yuka, and Think Dirty list Butyoctyl salicylate as a photostabilizer to boost the sun protection factor (SPF), and YES, it does, as it's a UV filter. All you need to do is go to one of these sites and look up the TOP choices for "100% Chemical or Mineral" sunscreens and check out the in-actives. What you will find is eye-opening! If BOS is listed in the inactive ingredients, don't believe the "chemical-free" claims, not to mention that the cosmetic form of Zinc oxide and Titanium dioxide, which are required to add them to a sunscreen product, are also chemicals. 

But don't despair; a handful of manufacturers tell the truth. One in Ontario, Canada, has done a great deal of research and found definitive proof that Butyloctyl salicylate is, in fact, Octisalate, and I commend them. See the information that they received from Sunjin, a Korean ingredient supplier.

Are "All Mineral" Claims Misleading?

Yes, you heard that right! ZnO and Ti02 are chemicals, and the inclusion of Butyloctyl salicylate in mineral sunscreens makes "all mineral" claims 100% misleading, not true, and a lie! These sunscreens have so-called minerals like zinc oxide and titanium dioxide as their active ingredients. The issue is the presence of chemical sunscreens in their inactive ingredients list, which means they aren't purely mineral-based. The worst part is how so many of them "BASH" chemicals, when they are hiding them in the actives, and they'll stick by: "Oh, it's 100% Mineral or Chemical Free - in the Active Ingredients", wow, stop poo poo-ing chemicals, you use them too.

There are some companies that make mineral sunscreens without using Butyloctyl salicylate, including one from Canada (Ava Isa) that I mentioned above and some others that are thick Zinc oxide creams.

Here's what you need to know:

• As a UV filter, it helps absorption like its twin, Octisalate, approved to a maximum of 5%. It helps to increase the SPF of mineral-based ingredients and helps to decrease the white cast.

The Final Verdict: Should You Be Concerned?

Incorporating Butyloctyl Salicylate in mineral sunscreens offers benefits – from better application to enhanced UV protection. But if you're committed to an all-natural, all-mineral sunscreen, this ingredient is a deal-breaker.

The other issue is that manufacturers reduce the quantity of "inorganic" UV filters, Zinc oxide, and Titanium dioxide so that you don't have the white cast/film on your skin. Still, it can lower the UVA protection that Zinc oxide provides.

The biggest red flag is that since it's unregulated, what is the percentage they are using in the in-actives? Is it the same as its twin, Octisalate, at 5%, or is it more, since it's in the in-actives and the percentages don't have to be listed?

So, why choose BU sunscreen sprays?

The debate is over: Butyloctyl salicylate is octisalate and cannot be used in an 'all-mineral' sunscreen.
