Episode 23 — Dirty Thirty Chemicals: The Hair Dye Chemical With an Asthma Bonus

Welcome to KeysPure.com's Dirty Thirty. I'm Bob Root. Today's chemical is P-Phenylenediamine — thankfully shortened to PPD — a hair colorant found in hair dye, shampoo, and hairspray. It's one of the most common ingredients in permanent hair color.

The health profile is extensive. PPD is an immune system and respiratory toxicant. It's a probable neurotoxin. It causes eczema. It's a possible nervous system, skin, kidney, and liver toxicant. It's an irritant. It may trigger asthma and gastritis. And animal studies have shown it to cause cancer.

PPD is also one of the leading causes of severe allergic contact dermatitis from cosmetics. The patch test instructions on box hair dyes exist precisely because of PPD's sensitization potential. Canada has restricted it. And yet it remains the dominant pigment in most hair color products on the market.

At Keys, we think healthy hair shouldn't come with a respiratory warning or an allergy risk. Clean hair care innovation has come a long way, and there are alternatives worth exploring. Visit KeysPure.com for more on our approach.

Dirty Thirty Episode Twenty-Three — PPD, the hair dye ingredient with a long list of side effects.

Episode 22 — Dirty Thirty Chemicals: The Plasticizer Hiding in Your Perfume

Hey, welcome back to KeysPure.com's Dirty Thirty. I'm Bob Root. Today's chemical is Phthalates — specifically Dibutyl Phthalates. 

These are plasticizers and solvents also used as fragrance ingredients. They show up in a massive range of cosmetics and personal care products — often hidden inside that one word we talked about in Episode Fourteen: "fragrance."

The European Union has banned them. And for good reason.

Phthalates are immune system toxicants. They're developmental and reproductive toxins — meaning they can affect fertility and fetal development. They're respiratory toxicants. They're probable neurotoxins. They're possible carcinogens and endocrine disruptors. And they are bio-accumulative in wildlife — meaning they build up in ecosystems and in animal tissue over time.

Studies have linked phthalate exposure to hormonal disruption in both males and females. They are particularly concerning during pregnancy and for young children. And because they hide inside "fragrance," consumers often have no idea they're being exposed.

At Keys, we use no synthetic fragrance and no phthalates — ever. Your sense of smell shouldn't come at the cost of your endocrine system. Visit KeysPure.com to learn more.

Episode Twenty-Two of the Dirty Thirty — Phthalates, the fragrance ingredient nobody told you about.

Episode 21 — Dirty Thirty Chemicals: The Petroleum Byproduct Pretending to Be Skincare

Welcome to KeysPure.com's Dirty Thirty. I'm Bob Root. Today it's Petrolatum — also known as petroleum jelly — and it is in more skincare products than most people realize.

Petrolatum forms a barrier on your skin. It makes lipsticks shiny and creams smoother. It's an inexpensive skin softener. And it comes from the same source as the stuff that goes into your gas tank.

The European Union has banned it. Why? Because Petrolatum may be contaminated with polycyclic aromatic hydrocarbons — PAHs — which are linked to cancer. The purity of petrolatum in cosmetics varies widely depending on the refining process, and not all manufacturers use the same standards.

Here's the layered irony — Petrolatum doesn't actually moisturize. It creates a seal on top of your skin that locks in existing moisture but adds none. So it's a cosmetic illusion of skincare that may carry contamination risks and does nothing to nourish your skin at a cellular level.

At Keys, we use botanical oils and plant-derived butters that nourish, not just seal. Visit KeysPure.com for the difference.

Dirty Thirty Episode Twenty-One — Petrolatum. Gasoline's cousin in your lip balm.

Episode 20 — Dirty Thirty Chemicals: The Preservatives Found in Breast Tumors

Hey, welcome back to KeysPure.com's Dirty Thirty. I'm Bob Root. Episode Twenty is about Parabens — Methyl, Ethyl, Propyl, and Butyl — the most widely used preservatives in the cosmetics industry.

Parabens are in an enormous number of personal care products. They're cheap, they work, and they've been used for decades. They're also a significant concern.

Parabens may alter hormone levels, possibly increasing the risk for certain types of cancer, impairing fertility, or altering fetal and child development. Here is the detail that should give everyone pause: studies have found parabens present in breast tumor tissue. Not in products. In tumors. They are a probable skin toxicant, and animal studies show brain and nervous system effects.

Now, the cosmetics industry will tell you the levels are too low to matter. But parabens are in shampoo, conditioner, body lotion, moisturizer, makeup — sometimes all used in the same morning routine. 

Cumulative daily exposure adds up in ways that single-product safety assessments don't capture.
At Keys, we've been paraben-free since the beginning. Visit KeysPure.com to see what that commitment looks like in a real product line.

Episode Twenty of the Dirty Thirty — Parabens. The most common preservative with the most uncomfortable research.

Episode 19 — Dirty Thirty Chemicals: The Sunscreen That Soaks Into Everything

Welcome to KeysPure.com's Dirty Thirty. I'm Bob Root. Today we're talking about Oxybenzone — also known as Benzophenone-3 — one of the most widely used chemical UV filters in conventional sunscreens and makeup.

Here's the cruel irony: it's in your sunscreen to protect you from damage, and it may be causing damage of its own.

Oxybenzone is associated with photoallergic reactions and immunotoxicity. It's a probable carcinogen and endocrine disruptor. It enhances skin absorption — meaning it doesn't just sit on top of your skin, it actually gets in and bioaccumulates to dangerous levels. Studies have found it in blood, urine, and breast milk. 

There's also evidence of biochemical cellular changes, developmental toxicity, and reproductive toxicity.
It's also worth noting that Oxybenzone is devastating to coral reefs, which is why Hawaii has banned it in sunscreens for environmental reasons. So it's harmful to you and harmful to the ocean. Quite an achievement.

At Keys, we use mineral-based sun protection — ingredients that sit on the skin rather than absorbing into it. Visit KeysPure.com to learn more.

Dirty Thirty Episode Nineteen — the sunscreen that needs sunscreen from itself.

Episode 18 — Dirty Thirty Chemicals: The Preservative That Attacks Your Nerves

Hey, you're listening to KeysPure.com's Dirty Thirty. I'm Bob Root. Today it's Methylisothiazolinone — also known as MI or MCI — and its partner, Methylchloroisothiazolinone. They're preservatives. They're in a lot of products. And they have a particularly concerning effect on the nervous system.

Both Canada and Japan have restricted these chemicals, and for good reason. Animal studies have shown that they restrict the growth of axons and dendrites — the critical extensions of nerve cells that allow neurons to communicate. They've also shown neurotoxicity and positive mutation results. 

Methylisothiazolinone can lead to a malfunction in the way neurons communicate with each other. And it is especially detrimental to a developing nervous system — making it particularly worrying in products used by children or pregnant women.

These are immune system toxicants. They show up in a wide range of cosmetics and personal care products. And because they're effective preservatives, manufacturers use them broadly without always fully considering the biological cost.

At Keys, we think protecting your nervous system is more important than extending a product's shelf life. Visit KeysPure.com to learn about our clean preservation approach.

Episode 17 — Dirty Thirty Chemicals- The Lipstick Ingredient From the Lead Age

Welcome to KeysPure.com's Dirty Thirty. I'm Bob Root. Episode Seventeen is about Lead and Lead Compounds — used as a colorant in hair dyes, hair products, and — brace yourself — traces have been found in some red lipsticks.

Lead. In lipstick. The stuff that you apply to your lips and reapply throughout the day, often before eating. That lead.

The health concerns are severe and well-documented. Lead is a probable carcinogen. It's a developmental, respiratory, gastrointestinal, and reproductive toxicant. It reduces fertility. Animal studies show metabolic, brain, and nervous system effects. Lead is also a suspected nano-scale ingredient — meaning it can absorb directly through the skin. Canada restricts it. And yet trace amounts continue to appear in cosmetic testing.
There is no safe level of lead exposure. It is a neurotoxin that accumulates in the body over time. The idea that it appears in beauty products — especially products designed for daily use on your lips — is deeply troubling.

At Keys, lead and lead compounds are an absolute no. Visit KeysPure.com to learn what we put in our products and, more importantly, what we don't.

Dirty Thirty Episode Seventeen — Lead in lipstick. Still shocking, still real.

Episode 16 — Dirty Thirty Chemicals: The Preservative You Can't Pronounce and Shouldn't Touch

Hey, welcome back to the Dirty Thirty at KeysPure.com. I'm Bob Root. Today's chemical wins the award for most unpronounceable name on the list: Iodopropynyl Butylcarbamate. Say that five times fast. Actually, don't — just stop buying products that contain it.

This is a preservative found in a wide range of cosmetics and personal care products. Japan has already restricted it. And while it might not have the most extensive rap sheet on our list, what it does have is real cause for concern.

Iodopropynyl Butylcarbamate is classified as a human toxicant. It's a possible liver and immune system toxin. It is significantly allergenic — meaning it can cause allergic reactions that range from mild irritation to serious sensitization. Once you develop a sensitivity to an allergen, it can persist for life.

Preservatives in skincare are necessary — products need to stay stable and bacteria-free. But there is a difference between preserving your product and potentially sensitizing your immune system. At Keys, we find preservation solutions that protect the formula, not ones that put your health at risk. Visit KeysPure.com to learn more.

Episode Sixteen of the Dirty Thirty — a preservative that's harder on you than the bacteria it's fighting.

Episode 15 — Dirty Thirty Chemicals: The Skin Lightener With a Dark Side

Welcome to KeysPure.com's Dirty Thirty. I'm Bob Root. Today we're talking about Hydroquinone — a skin bleaching agent used in skin fading products, facial moisturizers, anti-aging creams, sunscreens, hair color, and facial cleansers.

It's marketed as a solution for dark spots and uneven skin tone. The marketing is better than the safety profile.
Hydroquinone is an immune system and respiratory toxicant. It's a probable neurotoxin. It's a possible carcinogen and a general irritant. Animal studies have shown endocrine disruption — meaning potential hormonal interference. Canada restricts it. And yet it remains widely available in over-the-counter skin lightening products, sometimes at concentrations high enough to cause serious concern.

Here's the real issue: Hydroquinone treats a cosmetic concern while potentially introducing genuine health risks. The tradeoff simply isn't worth it when cleaner, safer approaches to skin tone and radiance exist using botanical ingredients.

At Keys, we formulate for results that don't compromise your long-term health. Visit KeysPure.com to see our approach to clean, effective skincare.

Episode 14 — Dirty Thirty Chemicals: The Word on Labels That Hides Everything

Hey, it's Bob Root at KeysPure.com, and welcome to one of the most important episodes of the Dirty Thirty — because today we're talking about one word that can hide up to three hundred chemicals: Fragrance. Or as it's sometimes listed in Europe, Parfum.

Fragrance is used as a deodorant, masking agent, and perfuming ingredient. It appears in an enormous number of cosmetics and personal care products. And here's the thing — because fragrance formulas are considered trade secrets, manufacturers are legally allowed to list every single ingredient under that one word without disclosing what any of them actually are.

That means one word on a label can contain between ten and three hundred different chemicals — many of which have never been tested for safety. These can include phthalates, benzyl acetate, and numerous other Dirty Thirty chemicals. Fragrance as a category is an immune system toxicant and a possible neurotoxin.

At Keys, we disclose every ingredient. Every single one. Because we think you deserve to know what you're putting on your skin. If a label just says "fragrance" and that's all you get — ask more questions. Visit KeysPure.com to see what full transparency looks like.
