Chemical Sensitivity List

This is the list, to the best of my knowledge, of what chemicals I have significant sensitivities to. There are certain to be things out there I don't know about yet, and compiling a full "safe" list of stuff that's okay to use would probably take years. The best I can offer is a set of what I know is not okay, some synonyms for the chemicals in question so that they can be looked up (by googling the MSDS for the product, usually), and general guides for what kind of stuff is unlikely to set me off. If you have a specific question, ask me.

I do own a respirator, which is proof against everything on this list -- so long as I know to wear it. If you have a concrete reason to suspect a place may not be safe, let me know and I'll carry the mask with me. I've had a great deal of experience with most of these, and if I can think straight, I know what to do.

The list of foods I can't eat is here.


No tolerance

Ethylene glycol monobutyl ether (EGBE)

Found in: Formula 409, Clorox Clean-Up, Expo (and other) whiteboard cleaner; a more comprehensive list can be found here.

AKA: Ethylene glycol butyl ether; 2-butoxy-1-ethanol; 2-Butoxy ethanol; monobutyl glycol ether; n-butoxyethanol; Butyl Cellosolve or n-Butyl Cellosolve; poly-solv eb; o-butyl ethylene glycol; 3-oxa-1-heptanol; Beta-butoxyethanol; BUCS; butoxyethanol; butyl glycol; Butyl oxitol; 2-Butoxyet; glycol butyl ether

Immediacy/severity: I can tell almost right away, but not before damage has been done. More mild exposures may not trigger any flags until I've been exposed to a great deal.

Interval after use: One week (indoors); one day (outdoors).

Symptoms: When particularly fresh: unthinking panic. At all times: severe brainfog, exhaustion, muscle weakness, anxiety attacks, Parkinson-type tremors, twitching, difficulty speaking, digestive disorders. Severe symptoms stick around for at least a week, muscle weakness and fatigue persist for three weeks or more.

Rescue: Get me out of there if I seem to be getting vague or panicky. 3g vitamin C, a B-50 tab, and some charcoal caps ASAP to combat immediate effects; for ongoing reactions, more C (for exhaustion and muscle weakness) and B vitamins (for nervous system effects) can help. Rubbing alcohol or vodka for wiping down my skin during detox can be useful.

Alternatives: 50-50 rubbing alcohol in water is a very effective whiteboard cleaner. For windows and counters, I recommend Bio-Kleen (Whole Foods and some other places carry it), but any of the more "natural" spray cleaners tend to be all right. Windex is questionable (see next entry).

Propylene glycol monobutyl ether, Ethylene glycol hexyl ether, other variants

Found in: almost all Windex, Swiffer WetJet; more products are getting it all the time, mostly surface cleaners.

AKA: Butoxy propanol

Immediacy/severity: Much like for EGBE.

Interval after use: Approximately 3 days (indoors); outdoors unknown.

Symptoms:This is the larger, milder cousin of EGBE. All the same symptoms but to a lesser degree, and they pass more quickly (about 3-4 days rather than a full week). Lingering effects are gone in about 10 days.

Rescue: As for EGBE.

Alternatives: As for EGBE. One type of Windex ("Mountain Berry", the reddish-purple one) does not contain any ethers and is safe, as are the Windex wipes. I have no idea whether the generic blue window cleaners have ethers in them, and I suspect it varies by store brand. A rule of thumb: if it mentions ammonia (e.g. "Glass Cleaner with Ammonia") it's more likely to be safe. Windex traded ammonia for ether as its grease-cutting agent, and I suspect no one uses both.

Glyphosate

Found in: RoundUp

AKA: I'm not sure whether it's glyphosate itself, or the other junk Monsanto adds to RoundUp that they aren't required to list on the label; as a result, I can't offer any other search terms.

Immediacy/severity: I know within about 10 minutes. Since I don't usually hang around where spraying is being done, exposure tends to be brief, but so long as the stuff is still wet I can get blindsided without knowing. My first hint is brainfog, which is notoriously difficult to notice right away.

Interval after use: Several hours, preferably a day. I can handle very brief exposures after the spray has dried, but I don't want to linger, and I shouldn't come in contact with sprayed items (including stuff in any drift radius) for a couple of days.

Symptoms: Brainfog, Parkinson-type tremors, twitches, muscle weakness, exhaustion. It lasts for a couple of days, depending on how severe the exposure was; when I walked into some spray in 2005, I was weak for about five days.

Rescue: Get me out of there if I'm getting vague. 3g of vitamin C to start with, and I may take more than that if necessary. B vitamins are worth a try if the tremors get annoying.

Alternatives: There are lots of other weed-killing methods out there for common weeds... but for some things (*cough*Bermudagrass*cough*) RoundUp is the only one that even comes close. If you must, use it, but consider using a paintbrush instead of a sprayer, and warn me if I'm likely to come into contact with it.

"Crazymaker"

Found in: I have no idea what this stuff is. The main place I run across it is newly-remodeled retail stores, such as Safeway and Longs; it isn't a common substance, I think, as I haven't had as much trouble with other newly-renovated buildings. The best guess I have is that it's either a new type of pressboard they're using for endcaps and shelving, or whatever glue is associated with it. I used to think it was some sort of flooring adhesive, but the Longs stores that got me haven't redone their floors recently.

AKA: No clue.

Immediacy/severity: No immediate reaction, which is very rare. I truly don't know I've been exposed until much later, usually 8-12 hours. It's what causes this one to make the list, as I can get very severe exposures without even knowing it.

Interval after use: Approximately two years. My local Safeway remodeled at least that long ago, and it's safe for me now.

Symptoms: None for 8-12 hours. After that: brainfog, severe anxiety attacks, depression, self-injurious impulses (I can handle them), flashes of anger, Parkinson-type tremors, muscle weakness. Thankfully, the whole cycle is usually done within 18 hours, but it's ruined a few weekends.

Rescue: B vitamins sometimes help a little. Mostly I just retreat to solitude and ride it out.

Alternatives: None.

Some tolerance

Lysol

Found in: Lysol and similar disinfectants (not to be confused with Pine-sol).

AKA: I haven't tracked down the specific ingredient.

Immediacy/severity: If it's fresh, I know within seconds. Residue a few hours old may trigger the feeling that something's up, but accumulated exposure doesn't seem to add to the reaction.

Interval after use: Ten to fifteen minutes in a well-ventilated room, more like an hour otherwise. Mostly I tell people not to use it in my presence unless I have a mask.

Symptoms: Brainfog and a touch of anxiety. (The latter may just be due to the nightmares I've had from time to time.) Tremors may show up with a particularly severe exposure.

Rescue: Fresh air, 3g of vitamin C, and some B vitamins if the tremors show up. I'll recover fairly quickly once I'm out of there.

Alternatives: The usual pack of disinfectants: bleach, ammonia, alcohol, soap and water; if you need an anti-microbial that isn't harsh, look into grapefruit-seed extract, which is what Bio-Kleen uses. Tea tree oil is effective, but it's a sensitizer (as is pine oil), so it may exacerbate any sensitivities the user already has.

Pyrethrins/synthetic pyrethroids

Found in: Raid and other standard insect sprays, bug bombs

AKA: cyclopropanecarboxylic acid. I suspect labeling laws require that they specifically refer to these as pyrethrin or pyrethroids.

Immediacy/severity: If it's fresh, I can taste it. Generally, if it isn't used right under my nose, I don't notice it; the worst reaction I had in recent memory was when I ate some food that hadn't been removed from the cupboard when someone sprayed for ants. (Don't do that!)

Interval after use: Long enough for the smell to go away; about 30 minutes or so for sprays, a couple of days for bug bombs. Don't bomb a house I'm spending a lot of time in.

Symptoms: Typical pesticide exposure: muscle weakness, exhaustion, brainfog. I know this one by the bitter taste in my mouth and excess salivation, which are trademarks for insecticide exposure. Basically, I have typical symptoms with a really low threshold.

Rescue: Fresh air and 3g of vitamin C. After that I get to wait it out.

Alternatives: There are a few "natural" bug sprays out there; my friend Jack found one he's especially fond of and refers to as "minty death" (active ingredient is mint oil): Victor Poison-Free Ant & Roach Killer. Gel and solid ant/roach baits are no problem. There's a host of nontoxic flea control methods out there, if you do a little searching.

Minor problems

These are the ones where symptoms last only as long as exposure, or no more than 20 minutes or so after I get to fresh air. I've noted how long it generally takes for the item to age before it's not an issue.

All of these are things where I will know within a minute or two whether the levels are too high, so I'll do a sniff test and let you know. Symptoms are simply brainfog, unless otherwise noted.

The safe list

These are the things I can list off the top of my head.


I really want to thank everyone who has worked and worried over making their houses safe for me, even in cases that I almost never show up. The support I've gotten has been far beyond what I would have expected, especially given the hassle. I'm touched.
