Why I Left Medicine to Build a Clean Home Products Brand (and What My Training Taught Me About Ingredients)

By Kristina Braly, MD — Founder, AEMBR

People ask me all the time: why would a physician leave medicine to make candles and laundry detergent? The short answer is that I couldn't unknow what I'd learned. The longer answer is this post.

I am a physician-founder. I built AEMBR in Houston, Texas, starting in October 2022 — not despite my medical training, but because of it. Fifteen years of studying biochemistry, toxicology, and pharmacology gave me a particular way of reading an ingredient label. And once I started reading the labels on the products filling my home — the laundry detergent, the candles, the room sprays — I couldn't stop noticing what wasn't being disclosed.

This is the story of that realization, what I did about it, and why ingredient transparency is the single non-negotiable principle behind everything AEMBR makes.

The Moment I Started Reading Labels Differently

It didn't happen all at once. It happened the way most important realizations do — gradually, then suddenly.

The gradual part: I'd been trained to read the literature carefully. In medicine, you learn to look past the headline and read the methods, the sample size, the funding source. You develop a healthy skepticism for marketing claims and a deep respect for mechanism. When I started applying that same framework to consumer product labels, the experience was — unsettling.

The sudden part: I was pregnant with my second child. I was washing infant onesies in a detergent I'd used for years. I looked at the label and realized I could not identify what most of the ingredients were, could not find full disclosure of what "fragrance" contained, and could not find a single third-party certification I recognized. I was a physician. If I couldn't interpret that label, what were parents without a toxicology background supposed to do?

That was the moment. Not a dramatic exit from a hospital corridor. Just a bottle of laundry detergent in my laundry room.

What Medical Training Actually Teaches You About Chemicals

Let me be specific, because "physician-founded" is a phrase that gets used a lot in the wellness space without much substance behind it.

Medical training teaches you that the dose makes the poison — but also that chronic low-level exposure is a real category of risk, distinct from acute toxicity. It teaches you to distinguish between "no evidence of harm" and "evidence of no harm." These are not the same thing, and the consumer products industry leans heavily on the former to imply the latter.

Specifically, I learned to pay attention to:

Endocrine-disrupting chemicals (EDCs): Compounds that interfere with hormone signaling at extremely low doses. The classic example in cleaning and fragrance products is phthalates — plasticizers used to stabilize synthetic fragrance that have documented associations with reproductive toxicity, developmental effects, and endocrine disruption in both human and animal studies.
Skin absorption vs. ingestion routes: We tend to assume "it's external, so it's fine." But the skin is a permeable membrane. Compounds applied to skin, especially repeatedly and in quantity (think: laundry residue left on fabric you wear all day), can achieve systemic exposure. Babies, whose skin barrier is still developing, are particularly vulnerable.
Cumulative body burden: No single product exposure is the whole story. We are simultaneously exposed to hundreds of synthetic chemicals through food, water, air, and personal care products. The regulatory frameworks governing most consumer products do not account for additive or synergistic effects. My training gave me the vocabulary to understand this — and to care about it.
The "fragrance" loophole: Under current FDA and IFRA rules, manufacturers can disclose fragrance as a single ingredient — even if that fragrance blend contains dozens of distinct chemical compounds, including phthalates, synthetic musks, and known sensitizers. This is not a conspiracy theory. It is a documented regulatory gap that I found unacceptable when I was buying products for my family.

Why I Chose Home Products — Not Supplements, Not Skincare

The clean beauty space has been growing for over a decade. Skincare and cosmetics reformulation is well underway. But the home products category — laundry detergent, room sprays, candles, cleaning solutions — has moved far more slowly.

There are a few reasons for this. Home products are purchased on price more often than personal care products. The category is dominated by legacy CPG giants with massive distribution. And consumers have been slower to apply the same scrutiny to what they clean their homes with as to what they put on their faces.

But consider the exposure math. A candle burning in your home is releasing compounds into the air you breathe for hours. Laundry detergent residue stays on every piece of clothing, every sheet, every towel you own. A room spray is an aerosol you're directly inhaling. The exposure frequency and duration for home products can easily exceed that of most skincare routines — and yet the ingredient scrutiny applied to them is dramatically lower.

That gap felt like both a problem and an opportunity.

The Ingredient Standards I Set Before I Made a Single Product

Before I formulated anything, I built a banned-ingredients list. Not based on what was currently fashionable in the wellness space. Based on the toxicological literature.

Every ingredient that went into an AEMBR product had to pass a three-part test:

Full disclosure: I could name it, publish it, and explain what it does. No proprietary blends, no "fragrance" catch-alls hiding undisclosed compounds.
Endocrine safety: No phthalates. No compounds with documented EDC activity at levels plausibly achievable through normal consumer use. This disqualified a significant portion of conventional fragrance formulations.
Carcinogen exclusion: No compounds on IARC Group 1 or Group 2A lists. No 1,4-dioxane (a contaminant found in some ethoxylated surfactants that is a probable human carcinogen). No benzene-releasing paraffin combustion if avoidable through wax selection.

These standards are not aspirational. They are the floor, not the ceiling — and they are why AEMBR products are formulated the way they are.

What I Learned About Candle Wax That Changed Everything

Paraffin is the most widely used candle wax in the world. It is a petroleum byproduct. When it burns, it releases VOCs — including low levels of benzene and toluene, both known carcinogens at sufficient exposure — along with soot that contains ultrafine particles.

The absolute risk from a single candle burned occasionally in a well-ventilated space is genuinely low. The IARC has not classified candle smoke as a human carcinogen. I want to be precise about that: the alarmist headlines about candles causing cancer are not well-supported by the current evidence base.

But "low absolute risk in a well-ventilated space with occasional use" is not the same standard I wanted to apply to a product people burn every day, in their homes, with their children, for years on end. That's the exposure profile of an AEMBR customer.

So I chose a coconut-apricot wax blend. Coconut wax burns cleanly with significantly lower soot emission than paraffin. It has excellent scent throw — meaning the fragrance diffuses effectively at lower temperatures, which means less volatile compound release. And it produces the slow, even, clean burn that lets AEMBR's candles achieve a 200-hour burn time in the full-size vessel.

Browse the AEMBR candle collection — every one is hand-poured in Houston in this coconut-apricot blend.

The Laundry Formulation Problem

Candles were the beginning. Laundry detergent was the harder problem.

Surfactants are the active cleaning agents in detergent. Not all surfactants are equal. Some of the most common — SLS (sodium lauryl sulfate) and SLES (sodium laureth sulfate) — are effective but carry well-documented skin irritation profiles, particularly for eczema-prone or sensitive skin. SLES, if not properly purified during manufacturing, can be contaminated with 1,4-dioxane.

I wanted a surfactant system that was genuinely effective at cold water washing temperatures (important for both energy efficiency and fabric preservation), free of the compounds above, and — critically — paired with a fragrance system I could fully disclose.

That last part is where most "clean" laundry detergents still fall short. They swap the obvious offenders (SLS, phosphates, optical brighteners) but keep a conventional "fragrance" ingredient that could contain anything. I wanted to close that gap completely.

AEMBR Laundry Powder uses plant-derived surfactants, no optical brighteners, no synthetic dyes, and a fully disclosed phthalate-free fragrance system. Every ingredient is named. That's the standard I set, and it's the standard we maintain.

On the Word "Non-Toxic"

I want to be honest about a term I use carefully: non-toxic.

"Non-toxic" is not a regulated term. The FDA does not define it. The FTC has guidance against unsubstantiated claims, but the bar for using "non-toxic" on a label is low and inconsistently enforced. Many products that describe themselves as non-toxic contain ingredients I would not use.

When AEMBR says "non-toxic," we mean something specific: no phthalates, no carcinogens on relevant regulatory and scientific watch lists, no compounds with documented endocrine disruption at consumer exposure levels, full ingredient disclosure, and no "fragrance" as a catch-all. That is what we mean, and we will show our work whenever asked.

What it doesn't mean: that AEMBR products are pharmacologically inert, that no one could theoretically have a sensitivity to any ingredient, or that we've run double-blind clinical trials on every formulation. I want to be clear about what the claim covers and what it doesn't.

Why Houston, and Why Now

AEMBR is made in Houston, Texas — hand-poured in small batches, by a team I know personally, in a facility I oversee. That's not a marketing story. It's a practical decision: when you care about ingredient integrity, proximity to production matters. I can verify what goes into every batch because I am physically close to where it happens.

The brand launched in October 2022. The timing was deliberate — I wanted to be part of the wave of consumer awareness around ingredient transparency, not catch up to it years later. The clean beauty shift had demonstrated that consumers with the information and the option would choose cleaner products. Home products were the next frontier.

Three years in, that thesis has held. Our customers are not primarily wellness-industry insiders or early-adopter health obsessives. They are parents, people with sensitive skin, people who have started reading labels and finding them lacking. They want what I wanted when I was standing in my laundry room, pregnant, holding a bottle I couldn't fully interpret: a product where I knew exactly what I was bringing into my home.

What My Medical Training Actually Changed — and What It Didn't

I want to close with something honest. Medical training made me a better formulator and a more rigorous ingredient evaluator. It gave me the vocabulary to engage with the toxicological literature and the scientific temperament to be skeptical of both alarmism and reassurance.

It did not make AEMBR's aesthetic. The Nordic minimalism, the scent philosophy, the obsession with the sensory experience of a clean home — that's not medical school. That's personal taste, iterative development, and years of knowing that a product can be genuinely safe and genuinely beautiful at the same time. Those two things are not in tension. The assumption that they are is exactly what I set out to disprove.

If you're new to AEMBR, the AEMBR Discovery Set is the most direct way to experience what I mean by that — a curated introduction to the scent library and the product philosophy in one place.

And if you have questions about specific ingredients or formulation decisions — ask. That's what the brand is built on: the belief that transparency and a good answer are always better than a polished non-answer.
