Do Certain Detergents/Additives Cause More Diaper Damage?

Earlier this week I posted a guide to making your own homemade detergent, with many cautions about the fact that you could risk diaper damage. In fact, Thirsties wrote an interesting post this week cautioning people against making their own detergents due to diaper damage from harsh ingredients that may be present in the detergent. So this is definitely a topic I want to look into.

I was interested in seeing what our numbers here had to say about it. I have found that sometimes the survey responses conflict with the advice given by many companies.  I don’t think any of these companies have some evil scheme behind them, they are caring people who want to be very sure that your diapers get the longest use out of them. But I do worry that there is not enough research behind many of the frowned-upon products. I don’t consider my survey legitimate research, but I do think that survey responses certainly give us a good picture of how different detergents are doing.

Previous Surveys: Maria at Change-Diapers surveyed over 500 cloth diapering individuals and “94% of respondents report no damage to their diapers. Those who selected ‘yes’ for damage to their diapers were unsure as to whether the leaking, repelling, fraying, delamination etc. was due to detergent. Less than 1/4 of those people were using a ‘no-no’ mainstream detergent. The remainder were using detergents that are recommended on ‘the lists’ etc.” This information is startling, and I wondered if the numbers would change if we only considered those who had used the detergents/additives for a long time.

Methods: To help answer this question, I used the over 2,200 responses to the Washing Diapers Survey to compare the diaper damage present*** in Cloth Diaper Safe detergents, Homemade Detergents, Tide, All Detergents (not the brand, but literally All detergents that were listed in the survey), and various additives*. I determined what detergents were deemed “Cloth Diaper Safe” by selecting those which received five stars in this handy table that Pin Stripes and Polka Dots made regarding cloth diaper safe detergents. I only looked at those who had used the detergent/additive for 9 months or more. I initially looked at how different the numbers were with different water types and found that there wasn’t a significant difference among the different detergents**.

 

What does this suggest?

Of those who used a detergent or additive for over 9 months, only 11% reported damage visible in their diapers.

There may not be as much correlation between detergents/additives and diaper damage as we think. Or at least not enough to worry about. We do see that Homemade detergent may be associated with higher damage, but again, the difference is small.

In other words, I do think many of us are a little too concerned about damaging our diapers.

Limitations: I want to make clear that each individual case may vary–these are estimates.There are also several additional variables that should be considered such as drying method, water type, machine type, diaper type, whether or not the diaper was purchased used, and the age of the diaper. It would also be interesting to clarify damage type. Respondents from both my survey and Maria’s noted things such as worn velcro as damage and that may classify more as diaper wear.

Conclusion: It is my hope that we explore this area of the cloth diapering community a little more closely. As you know, I feel like we are making cloth diapering a little more difficult than it need to be. And I know you will probably look at this chart and scream “HYPOCRITE!” I do wish there was stronger evidence that specifically looked at how different detergents worked on cloth diapers specifically and on different machine types, diaper types, water types, etc. Our survey responses certainly give us a great glimpse at that, but I would love if a more controlled experiment existed out there specifically geared towards cloth diapers. I felt that this was a great suggestion that Maria from Change-Diapers put on my Facebook Page regarding what companies can do to feel confident in their washing/warranty regulations. She suggest that companies have diapers “washed 18  at a time, every 3 days for whatever the typical life expectancy on their diaper is, checked after every 10 or so washes… do this in soft water, hard water, top load HE, front load HE and standard top loading machines. Chlorinated city water & well water, with and without a water softener, and in different brand machines.” I agree with that completely, but I also understand that a company may not have the funds to do that. It is my hope that a company can invest the money to create a controlled experiment to cover this topic and that if companies caution against certain detergents/additives, they would be able to cite that experiment (or one like it) as their source.

What are your thoughts? Have you experienced diaper damage? Do you think your detergent is to blame?

* Additives were based on those who used them 90% of the time

** I did find that those with hard water experienced more damage with using homemade detergent than those with normal water. Those with normal water experienced more damage with cloth diaper safe detergent than those with hard water. But I do not feel as though these differences were statistically significant.

*** Respondents rated presence of diaper damage on a 5 point scale, with 1 being “no damage” and 5 being “severe damage.” I considered responses in the 3-5 range as those indicating damage, since many who indicated a level of “2” also noted that it was in diapers that they either purchased used or had for a long time.
 
I want to re-iterate my belief that I don’t think cloth diaper companies are bad and this article is in no way intended to attack them. I know many of these company owners and they are wonderful, caring people who are just trying to get the diaper to last a long time and I would likely be just as cautious as them if I were in their shoes. However, I hope this article can be read in such a way that perhaps we re-consider our current cloth diaper laundering “No-no” list.

Tara Porter began using cloth diapers in 2011 when she felt that using disposable diapers was costing too much money. The problem was, a lot of the highly recommended diapers weren’t working for her baby. What she finally discovered was that her baby was skinny and a heavy wetter, and that diapers worked differently for those baby types. Because of her professional work with survey design and statistics, she designed Padded Tush Stats as a way to determine how different cloth diapers worked on different babies.

Tara moved on to other career endeavors in 2014 but can still be found online blogging about health and fitness at Fit Baby Steps.

    When you do a proper research could you please include soap nuts or soap berries in the categories of detergents for us super organic mommies? I have been wondering if my delamination is due to buying cheaper diapers, possible dryer time, or bleach accidentally added. There really are so many factors!

    • Tara

      Well I don’t think I will be doing a formal research study that has more controls like I suggest in this article, simply because I don’t have the funds, but hopefully if someone does take on this project, they consider soap nuts. Just a note, the damage for soap nuts is 7%, but I didn’t have enough responses for me to feel like that is a statistically reliable term (15 just isn’t enough responses).

      There definitely are TONS of factors involved.

    The inside of my friend’s BG 3.0’s repel liquid – the suedecloth is almost as waterproof as the PUL!! She has hard water and uses homemade detergent (washing soda, baking soda and grated Ivory). Do you suppose this damage is caused by the water type or the detergent? Is there a way to reverse it?
    Thanks!

    • Tara

      Has she stripped them? Repelling isn’t damage, it is generally buildup.

    • Lily Ivey

      Ivory soap is soap not detergent. It will build up and cause repelling. I second the need for stripping.

      • Tara

        That would be a Sustainablebabyish Magic Fitted. Well loved :)

    Hi Tara,
    I am a little off topic but wondering what brand of diaper is in this photo. Other than it was used/washed VERY well it looks super soft and comfy. Could you tell me where to find them.
    Thanks!

    Help! I’ve used cloth diapers for the last 15 months. The last month however my cloth diapers started repelling water. They don’t stink they just don’t absorb water anymore. I’ve tried everything I could think of – then decided maybe they were just worn out? So I ordered 12 new diapers from Thirsties. All of my previous diapers were bought used so I ran these through a wash like I do all new clothes and now they repell as well. Any suggestions on what to do now?

    • Tara

      I am so sorry to hear about this. A few questions for you…have you used any diaper creams lately? What is your detergent and washing routine? Do you know if you have soft water?

    Purely cosmetic, I know, but can anyone say how Tide affects colors over time? (I’m a sucker for brights.)

    • http://www.makingitworkblog.com/ Carolyn Russell

      I’ve been using Tide on my clothes for years and never noticed anything about the colors fading (well, other than clothes just wearing out over time!) My diapers seem fine, as well :)

  • Ashley L

    I feel much better now that I know there really isn’t much difference of diaper damage with detergent used (all variables considered of course). I use Tide because none of the detergents for cloth diapers I’ve tried seem to get them completely clean. I love tide!
