How Much Tuna is Safe to Eat?

Just came across a cool tool over at the Environmental Working Group’s site. You enter in your weight (in pounds) and it tells you how much tuna — albacore, light — it’s safe for you to eat each week.

Very useful.

Product Review: Avalon Organics “Vitamin C Vitality Facial Serum”

After yesterday’s eye-opening expedition down facial moisturizing product lane, I thought it was long past time for me to review some of my other daily-use applications.

Today’s product review is for Avalon Organics “Vitamin C Vitality Facial Serum” from their “Vitamin C” product line.  It’s a serum I use fresh out of the shower and under my other face moisturizer on a daily basis.

Avalon Organics Vitamin C Vitality Serum

Feels great going on, and I find it’s good for making those dark circles under my eyes less prominent – especially in combination with one of Avalon Organics’ other face creams in the Vitamin C line.  Plus, unlike products in the lavender line, it doesn’t tend to make me break out – a definite plus.

So here is the catch: the Skin Deep Cosmetic Safety database gives it a 6/10, or “moderate hazard” rating.

What I’m trying to figure out is why, given that the highest warning number for any of the ingredients listed on their site is a “4″.

Curious to find out more?  You can go here to see the rating on the site.  See if you can figure out why they’re slamming this product, because I’m stumped.

so … do vitamins help or not? studies show …

An old friend, who also happens to be a doctor down in the States, sent me a really interesting article from the New York Times yesterday on the results of studies done on vitamin consumption and their impact on health (News Keeps Getting Worse for Vitamins by Tara Parker-Pope, November 20, 2008).

Factoid #1: Long-term ingestion of vitamins C and/or E don’t seem to help prevent cancer.

Factoid #2: Vitamins C and E do not seem to prevent heart disease.

Factoid #3: Vitamin C seems to not only protect healthy cells but cancerous cells as well.

Factoid #4: Vitamin E, especially when taken in combination with other vitamins and/or minerals, seems to actually account for a HIGHER mortality rate (4% if only taking vitamin E — 6% if taking vitamin E in combination with other vitamins/minerals — according to one study) than taking nothing at all.

Factoid #5: In one study, people being treated with radiation for neck and head cancer were given doses of vitamin E.  It seemed to reduce the side-effects of the radiation, but the cancer recurrence rates seemed to be higher in the group taking vitamin E.

On a positive note … well, it’s not all bad.  B12/folic acid is still a good thing if you’re a woman of child-bearing age.  And taking calcium does seem to help with osteoperosis if you’re a woman over the age of 65.

It’s a fascinating article – suggest you check it out.

Product Review: Germ-Force by Prairie Naturals

Today’s product review (after a relatively lengthy hiatus, natch) is for something I picked up over the weekend to replace the Purell bottle on my desk prior to the start of the hard-core flu season.

Product: Germ-Force, produced by Prairie Naturals.

Sub-Heading: “moisturizing hand sanitizer | antibacterial | paraben free

Ingredient List:

1.  denatured grain alcohol

This ingredient is not specifically tagged in the Skin Deep database.  The closest matches I could find were for either “alcohol denatured” (weighing in at a hefty 4/10) or “alcohol, denatured 38F” (weighing in at a much more comfortable 0/10) or “alcohol, denatured 3A” (also at a nice 0/10 on the hazard scale).  

If we’re talking about the 4/10 rating, the specific risks were:

• Cancer
• Developmental/Reproductive Toxicity
• Strong Concern:Multiple, Additive Exposure Sources
• Strong Concern:Enhanced Skin Absorption
• Moderate Concern:Organ System Toxicity (non-reproductive)
• Moderate Concern: Irritation (skin, eyes or lungs)

2. aloe vera gel

This ingredient was ranked at 1/10 on the hazard risk scale, which classifies as a “low hazard” risk.   Specific risks based on the SkinDeep ranking system include:

• Developmental/Reproductive Toxicity
• Violations, Restrictions & Warnings
• Lesser or Emerging Concerns:  Organ System Toxicity (non-reproductive)
• Lesser or Emerging Concerns:  Data Gaps

3. vegetable glycerin

This ingredient was ranked at 1/10 on the hazard risk scale, which classifies as a “low hazard” risk.  The specific risks are listed as follows:

• Moderate Concern: Organ System Toxicity (non-reproductive)
• Lesser or Emerging Concern: Data Gaps

4. natural fragrance of green apple

No match was found for this ingredient.

For more information on Prairie Naturals in the Skin Deep Database, here is where to go.

Summary: 

Out of four ingredients, two rated a 1/10, one rated either a 0/10 or a 4/10 (so I’m going to split the difference at 2/10), and one contained no information for the substance so I’m not going to include it in the ranking.

Based on the above, it looks like this product nets out at approximately 1.333 on the hazard rankings on a scale from 0-10.  Low hazard.

What do you think?  Are you comfortable with this?

Safety Check: Avalon Organics CoQ10 Facial Cleansing Milk

Switched to a new face wash a couple of days ago with my fingers crossed. Avalon Organics — usually a good company. Right?

I happen to like this product. My previous facial cleansing gel (also an Avalon product) was making my face red if I left it on for more than a couple of minutes in the shower. Not this one. Either it’s the creamy nature of the cleanser, or maybe it’s because the weather is starting to get cooler out again so my face isn’t as oily. After all, the CoQ10 product is billed as being for normal-to-dry skin … which mine tends to be only when the weather cools and the humidity level drops. It also smells reasonably nice if you like lavender and it doesn’t leave that greasy layer of yuck that many creamy cleansers do.

The SkinDeep Cosmetics Database rates it at 4/10 or moderate risk.

Whew.

For the full product report, you can take a look here.

Except that … well, the list of ingredients detailed at the Avalon site doesn’t match the list found on the SkinDeep site. Starting to wonder about the accuracy of the database when it comes to having the most current formulations now, so I’m going to go with the list of ingredients on the Avalon site. Then compare them against the ratings for the individual substances myself in the database and see where things net out.

Here is what you’re getting into if you choose to use this product:

INGREDIENT LIST:
1. angustifolia (lavender) flower
0/10 (low risk)

2/10 (low hazard risk) NOTE: Risks include violations, restrictions & warnings, organ system toxicity (non-reproductive), irritation (skin, eyes or lungs) and data gaps.

29. other essential oils
4/10 (moderate risk)

Looks to me as though Avalon has changed its formulation to decrease its risky ingredients. My average risk rating, based on the total of all rankings out of ten then divided by the total number of ingredients, has this product with a final risk rating of 1.31/10.

What do you think? Is this product safe enough for you to use?

Safety Check: Purell Hand Sanitizer (Original) with Moisturizers and Vitamin E

I hate getting sick.

In fact, after two winters of various cyclical maladies, I’ve gotten to be a bit of a germaphobe.

Enter the classic germ prevention method: Purell Hand Sanitizer. It’s everywhere in Toronto hospitals and medical centres these days; I also have one on my desk at work.

But how safe is it — really?

The Skin Deep site is not too clear on that. It has several Purell products listed, with safety ratings ranging from 5/10 to 7/10, but not the specific one sitting on my desk. So let’s take a look at the ingredient list and see where we’re at here.

MEDICINAL INGREDIENT:

1. Ethyl Alcohol 62% (a.k.a. “ethanol”)
Skin Deep Rating: 4-5/10 depending on useage

NON-MEDICINAL INGREDIENTS:

2. aminomethyl propanol
Skin Deep Rating: 3/10 (moderate hazard)

3. carbomer
Skin Deep Rating: 0/10 (low risk)

4. fragrance
Skin Deep Rating: 7/10
That’s not good at all!

5. glycerin
Skin Deep Rating: 2/10
NOTE: Includes cancer and developmental/reproductive toxicity

6. isopropyl myristate
Skin Deep Rating: 1/10 (low risk)

7. propylene glycol
Skin Deep Rating: 4/10 (moderate hazard)

8. tocopheryl acetate (Vitamin E acetate)
Skin Deep Rating: 4/10
NOTE: Includes risks for allergies/immunotoxicity as well as contamination concerns for hydroquinone (This is bad – hydroquinone, according to Skin Deep, runs the gamut of bad things from cancer to developmental/reproductive toxicity and beyond)

9. water
Skin Deep Rating: 0/10 (“innocuous”)

Ouch. So I’m feeling a little more nervous about this bottle of liquified gunk sitting on my desk now. Maybe I should just make a point of washing my hands more often instead …

Safety Check: Avalon Organic Botanicals Lemon Clarifying Shampoo

Product: Avalon Organic Botanicals Lemon Clarifying Shampoo
Skin Deep Rating: N/A (not listed in the database)

This is a product used by two out of the three members of my household on a regular basis, as well as by at least two other extended family members. We’ve had it in the bathroom for at least two years now … thought it was time to check out the ingredients and do a bit of a reality check here.

NOTE: The main hazard rating for this one is a link to Cancer. Damn!

9. chamomilla recutita (chamomile) flower extract
Skin Deep Rating: 1/10 (low hazard)*

Skin Deep Rating: 0/10 (low hazard)

11. vegetable glycerin

Average rating of all listed ingredients (with “N/A” products counting as “0″): 1.17/10

Safety Check: Avalon Organic Botanicals Therapeutic Facial Cleansing Gel Lavender

Well this is disturbing.

A couple of years ago I made the switch from the more conventional facial products from the drug store to using something I *thought* would be safer. It said “organics”. It’s sold at the health food store. Should make it safe. Right?

Here is the product in question:

Avalon Organic Botanicals Therapeutic Facial Cleansing Gel Lavender.
Frequency of use: daily with my morning shower.
Skin Deep Rating: 5/10 (“moderate” risk)

So, according to the Skin Deep database, this product contains ingredients which rank as high as 5/10 on the toxicity scale. However, I went and looked at the ingredient list that Avalon has listed on the site for this product. It doesn’t match the one in the Skin Deep database.

Here is what is on the site label:

Organic lavandula angustifolia (lavender), chamomilla recutita (chamomile) and camellia sinensis (white tea) extracts (aqueous)(1), organic arnica montana extract(2), cocamidopropyl betaine, disodium oleamido succinate, sodium cocoyl glutamate, sodium cocoyl isethionate, vegetable glycerin, organic aloe barbadensis(1), glycereth-7 cocoate, citric acid, phospholipids, panthenol (pro-vitamin B5), sodium PCA, allantoin, dipotassium glycyrrhizinate (licorice root), organic borago officinalis (borage) and linum usitatissimum (flax) oils(1), phenoxyethanol, rosa canina (rose hip) oil, benzyl alcohol, organic lavandula angustifolia (lavender) oil(3) and other essential oils.

So … since it doesn’t actually match what’s in the Skin Deep site … I’ve decided to break it down ingredient by ingredient.

1. Organic lavandula angustifolia (lavender)
Skin Deep Ingredient Rating: 1/10 (low risk)

2. chamomilla recutita (chamomile) extract
Skin Deep Rating: 0/10 (no risk)

3. camellia sinensis (white tea) extract (aqueous)
Skin Deep Rating: 2/10 (low risk)

4. organic arnica montana extract
Skin Deep Rating (based on “flower” extract): 2/10 (low risk)

5. cocamidopropyl betaine
Skin Deep Rating: 5/10 (moderate hazard)
Well, that’s not good …

6. disodium oleamido succinate
Skin Deep Rating: 0/10 (no hazard)

7. sodium cocoyl glutamate
Skin Deep Rating: 0/10

8. sodium cocoyl isethionate
Skin Deep Rating: 1/10 (low risk)

9. vegetable glycerin
Skin Deep Rating: 1/10

10. aloe barbadensis
Skin Deep Rating (aloe barbadensis – general): 2/10
Skin Deep Rating (leaf extract): 1/10
Skin Deep Rating (gel): 1/10

11. glycereth-7 cocoate
Skin Deep Risk: 0/10

12. citric acid
Skin Deep Rating: 4/10 (moderate risk)

13. phospholipids
Skin Deep Rating: 0/10

14. panthenol (pro-vitamin B5)
Skin Deep Rating: 2/10 (low hazard risk)

15. sodium PCA
Skin Deep Rating: 2/10 (low hazard risk)

16. allantoin
Skin Deep Rating: 0/10 (low hazard risk)

17. dipotassium glycyrrhizinate (licorice root)
Skin Deep Rating: 1/10 (low hazard risk)

18. organic borago officinalis (borage) oil
Skin Deep Rating: 0/10

19. organic linum usitatissimum (flax) oil
Skin Deep Rating: 0/10

20. phenoxyethanol
Skin Deep Rating: 4/10 (moderate hazard risk)

21. rosa canina (rose hip) oil
Skin Deep Rating: 0/10

22. benzyl alcohol
Skin Deep Rating: 6/10 (moderate hazard risk) –> yikes!

23. organic lavandula angustifolia (lavender) oil(3) and other essential oils.
Skin Deep Rating: 2/10

So … based on an ingredient by ingredient rating breakdown, taking the highest of all possible options (if there is more than one score on a particular item), then averaging them all out … I get 1.52/10 as an overall score for this product. Which leads me to wonder about the Skin Deep rating system and/or whether or not Avalon improved its ingredient list between the original examination done by Skin Deep and now.

For what it’s worth, there are clearly a few ingredients here to be concerned about. But I’m feeling a bit better now than I was when I first checked the rating for this product.

What I’ve learned from this exercise is that the following ingredients are ones to watch for in “natural” products:

1. benzyl alcohol (6/10)
2. cocamidopropyl betaine (5/10)
3. phenoxyethanol (4/10)
4. citric acid (4/10)

What do you think?
