• Soap Berry Liquid Detergent: Efficacy Test

NaturOli’s soap nut liquid detergent goes toe to toe with leading chemical detergents in independent laboratory testing to compare cleaning power. This is the first time in history an independent US laboratory detergent comparison included soap nuts.

Recently documented (June, 2009) via laboratory efficacy studies, soap nuts and saponin are proved equivalent in cleaning power to the some of the most popular mainstream synthetic chemical detergents on the market. The testing was for cleaning power only. There is no consideration given to the “mile long” list of additional benefits (either health or environmental) from the use of soap berries and saponin. For most, soap nuts sound to good to be true – but this is real. These are the facts. Here is the proof.

In June of this year, a diluted version of NaturOli’s Extreme 18X concentrated laundry soap was provided to Specialized Technology Resources (STR) in Canton, Massachusetts for comparative testing and analysis. The dilution of the 18X was done to approximate a one-ounce to one-ounce single load comparison. One ounce of “pure” Extreme 18X will wash approximately six to 12 loads. A full ounce of Extreme 18X would not make for a realistic comparison. It was diluted to equate to a single load dosage to compare apples to apples.

Comparisons were made against Tide 2X Ultra, Tide Free 2X Ultra, Seventh Generation Free and Clear 3X Concentrate and Method’s 3X Detergent Concentrate. Tests were conducted using a cold water (70F), normal wash cycle and used top loading vertical axis washing machines.

In the final analysis it is quoted by STR, “At approximately a 35% lower Use Level than both the Tide and Seventh Generation products and at the same Use Level as the Method product (NaturOli’s liquid soap nut detergent) demonstrated approximately 98% Tide’s, Seventh Generation’s and Method’s Overall Soil Removal Capability.”

That’s using 35% less product in the comparison with Tide and Seventh Generation. The tests were conducted using cold water with vertical agitation – one of saponin’s most difficult scenarios for maximum effectiveness. Amazing! Of the numerous tests, even with additional enzyme boosters by the competitive brands, the very lowest comparative results proved 91-93% effectiveness. There are currently no enzyme boosters whatsoever added in NaturOli’s Extreme 18X saponin laundry soap. This is a due to NaturOli maintaining the product’s purity.

Virtually across the board in every single test the results were comparable. The tests compared soiling by dust, clay, coffee, cosmetics, grape juice, grass, blue ball point pen, spaghetti sauce, motor oil and more. Test evaluated results on fabrics such as cotton, polyester and blends.

Hands down, this is a major victory for saponin over synthetic chemical detergents. Please don’t think that the supposedly “green” products that the saponin detergent was compared are actually “green”. Read the ingredients for yourself. They are far from it. SLS is still a primary ingredient.

Bottom line: The first of NaturOli’s saponin-based detergents went head to head with the leading detergents on the market and the jury called it a draw. Given that the emphasis of saponin-based products is placed on purity from all hazardous chemicals, this is a monumental achievement.

• Liquid or Powder: Better Natural Laundry Results?

Soap nut liquids and powders are growing rapidly in popularity because they are more inline with how we typically wash laundry today – primarily liquids. Statistics show liquid detergents are over 90% of the detergent market and are still growing. The traditional soap nut method (the dried fruits in a wash bag) is so radically different it warrants its own post. I will discuss the traditional method of using soap nuts or soapberries in a separate article. For now we will look at only the pro and cons of soap nuts liquids and soap nuts powder.

Use of soap nuts date back to antiquity, but modern manufacturers know little to nothing about them. Hence, don’t expect to find a machine with a soap nuts compartment for quite some time. So, where does that leave us? The answer is very simple: Use of our common sense. All that is required is a basic, understanding of how your washing machine and soap nuts work. Armed with that fundamental knowledge, you will find all your answers.

During a recent trip to look at new washers and dryers, I must admit that they appear to be quite complex, but appearances are just that. The fundamentals are still similar to that 20-year-old Maytag.

An aside: Ironically, if we would have ever been taught the real science of washing and cleaning (other than the technologically improved energy saving mechanics), we could use that 20 year old Maytag and get fabulous results without ever using a drop more water than absolutely necessary. We have been trained to wait for “somebody” to come out with a better way so we can purchase that better way. In essence we are trained to be dependent on businesses to offer “push-button” solutions. That is exactly how big business wants us to think. I believe that we finally are beginning to realize that if we use our brains and learn more, we can stop waiting for the next solution to be sold to us. Knowledge is power. There is truly a great deal to know about effective cleaning and washing that most of us simply do not know and have never been taught – or taught properly. I believe the Internet and information age are going to change many routine and everyday ways we do things in our lives. I believe the future holds many age-old fundamentals that will be rediscovered. The time is coming when less money and resources will be wasted on needless things, and those resources will be rerouted to development of products that will genuinely improve the overall quality of life. The recent economic downturn coupled with the green movement has provided very good reasons to take a second look at how we live our lives. That “second look” is very likely to evolve into an entirely new era for mankind. A very interesting thing about knowledge – when you get a little, you want more.

Getting back on track: There are more bells and whistles in the new machines. There are some extra features and cycles available. Some of them can be very useful. Just keep in mind that we must simply think a little differently and make adjustments as needed to accommodate proper use of soap nuts. Experimentation is always helpful. From household to household there are many variables. Some are environmental. Some are due to our personal habits. Regardless, we are all different and we do things a bit differently. Finding our own personal best way is a function of thought and such experimentation.

Soap nuts are available in liquid and powder forms in addition to their raw form (right off the tree and dried). The soap nuts liquids and soap nuts powders can be made at home or specific formulations can be purchased from a handful of developers. That makes usage much more similar to using standard and HE detergents, and therefore much simpler. However, note that the manufacturer of your machine has written instructions based upon typical “store-bought” detergents and additives – not soap nuts detergents. And once you are using soap nuts, it’s a whole new ballgame. For example: the fabric softener compartment. It is simply not needed at all anymore. (That is going to make some companies unhappy.) Some other compartment will prove to be useful.

Now stick with me on this for it is very important: If you have a high efficiency (HE) washer that requires HE detergents, soap nuts in any form are ideal when used properly because they are naturally low sudsing. They blow away every HE detergent on the market. If you have a standard machine, they are still ideal. Many people get confused at this juncture. What you must realize is that suds are not required to clean. Nor are they a barometer for evaluating the cleaning that is occurring in your washer. That is one of the big myths regarding detergents and soaps. Regardless of machine type only three things are required for effective washing of everyday laundry:

1 – A surfactant to lessen the water surface tension allowing it to break up and loosen dirt and grime.

2 – Adequate water flow.

3 – Agitation.

That’s it. So, for now try not to get hung up on the whole suds issue. I am going to address suds at great length in another article.

Given the above, now let us get to the nitty-gritty of using soap nuts liquids and powders. The variables here (aside from amounts to use) are primarily the concentration and potency of the liquid, and/or the fineness of the powder. If you are making your own liquid then the potency of saponin in the liquid will vary depending upon how you make it. If you are using a CleanNut, Terra, or Maggies soap nut detergent, they will be used very much like all others (a little more or a little less depending upon the machine type. Water hardness is a variable here. If you have hard water use a little more. Experiment and let the results speak for themselves. Back to the suds issue, do not use suds as a barometer to gauge results. Results are determined when your laundry has dried. Does it look and smell clean and fresh? Is it soft and absorbent? This is where you gauge results. This is where it counts. I had to laugh one day as a woman explained her first experience with soap nuts. She said, “I felt like I was just washing in water.” But stood in amazement at the dirtiness of the water coming from a “not all that dirty” load of laundry. She was astonished at how fresh, clean and soft her laundry came out. (She’s another one who will never look back.)

Comparison: 96 loads with 18X soap nut liquid concentrate

Comparison: 96 loads with 18X soap nut liquid concentrate

If you are using NaturOli’s EXTREME 18X soap nuts liquid concentrate this is quite different. The same “little more” or “little less” principle still applies, but this is a very highly concentrated soap nuts detergent. You will typically use only a half to one teaspoon per load. No kidding. That’s just a squirt or two if using the dispenser bottle. That’s a no-brainer. You can use the compartment as you would with any liquid detergent. You simply use much less. You are probably best to start with a teaspoon (2 squirts) and then cut back and compare. Overcome that feeling of needing more – and let the end results speak for themselves. This is where “concentrated” takes on an entirely new meaning. It is actually more of a pure soap nut extract. A small 8 ounce bottle of EXTREME 18X will have as much or more cleaning power than those  that come in a big 32 or even 64-ounce jug. I know, it’s tough to grasp that, but that is only because of the brainwashing factor again. NaturOli set out to produce the greenest detergent and cleaner possible – and did (winning a major award in the process). There is no laundry soap on the planet with a lower carbon footprint. Why do companies  ship all that water anyway? For that totally pure, unaltered, soap nuts clean and fresh result, you will be happiest with EXTREME 18X. It contains no essential oils that can leave residue and cause “wicking” of the fabric fibers, plus it is totally unscented. If you desire a scent I recommend using an absorbent cloth with a little of your scent of choice and tossing it in the dryer. Use more or less as desired. The oils will not impact the cleaning effects when used in such fashion.

If you are using soap nuts powder, you want it to be as fine as you can possibly get it (dust like is preferred). It’s likely better to purchase finely pre-ground and sifted. A course grind and/or a short wash cycle will result in much saponin just going down the drain and being wasted. It won’t have time to fully release its saponin. (Grinding your own sounds easy enough, but it is a bit trickier than you may think. The shells must be very dry first, and if you have a grinder that will produce an ultra-fine powder, plus a fine filter, an airborne soap nut “dust” will be difficult to avoid. The dust will be irritating if inhaled, or if gotten into eyes. I recommend purchasing it ready-made for use.) Approximately a teaspoon of very fine, quality soap nut powder (added into the powder compartment or directly in with your laundry) will wash an average load. Using powder may be a less economical method of using soap nuts because you’ll likely use more soap nuts than required if reusing them in the wash bag method, or if using liquid. Liquid ensures optimal use of the saponin in the berries.

In all cases, if you are adding salts, water softeners, sodium percarbonate (oxy-bleach basically), washing soda, vinegar, etc. to adjust your water’s pH level and/or for whitening and cleaning boosters, that’s totally fine – plus part of the fun! Experimentation is key to obtaining consistently excellent results.

btw: Soap nuts powder makes for an awesome green scouring powder. That is predominantly what I use powder for. Forget about the toxic Comet and rubber gloves! Powder works great!

There is no rocket science here. Most of this is plain, old-fashioned common sense. The only real hurdle is changing the way we think, and some old habits. Good results are what we are striving for. It may take a couple loads to dial in the best results for your particular scenario, but you will soon know exactly what to do. If you have a pre-wash and a main wash cycle, simply use them as your owner’s manual suggests.

It is noteworthy to point out that with soap nuts you really don’t need a second rinse cycle unless your laundry is very dirty. In most cases, that second rinse is to help flush out all the chemicals in the fabrics. Since we aren’t using chemicals with soap nuts it is no longer needed. It becomes a matter of choice, not necessity. So you do have an opportunity to save quite a bit of water. That’s a nice plus.

I hope this has helped you. It is actually hard to really do something very wrong when using soap nuts liquid or powder. If you are not satisfied with the results, take a look at what you did and make some adjustments. If you have very hard water then you will typically need to use more than average amounts. Once again, let the final results be your finished laundry. Once you have dialed in what is right for you, your laundry will be clean, fresh, soft and absorbent – unlike you have ever experienced before. If you are like the vast majority, you will never want to use anything except soap nuts detergents again.
