The Science of Bubbles

If you’ve tried our soap before, you may have noticed that it lathers much differently than commercial soap.  Natural soaps tend to have a much creamier lather, and not as many bubbles.

Why is that you ask?

Now, I don’t know if you’ve ever tried to blow a bubble with either pure water or oil, but it just doesn’t work (side note, Smarty Pants: sticking a straw in a cup full of either one and blowing bubbles does not count).  The surface tension of both solutions is too strong for any air bubbles to last.  That’s where soap comes in.  Soap molecules are made of long carbon and hydrogen chains with one hydrophilic end and one hydrophobic end, which is just a fancy way of saying that one end of the chain likes to be in water and the other end hates it.

Stick with me here I’m going to get a little soap nerdy:)

So, in a solution of soap and water, the ends that hate water (hydrophobic) want to get out at all cost.  They come to the surface, essentially pushing all the water out of the way.  The further the distance between water molecules, the weaker the surface tension of the water.  Some water molecules are bound to get stuck in between, however, and the soap molecules surround the trapped water molecules with the water-loving ends pointing outward towards the rest of the solution and the water-hating ends pointing inside.

Whew! So what does that mean? It means we are left with a bubble! Just some lonely water molecules sandwiched between soap molecules.

Here’s the kicker, though! Commercial soaps add a lot of harsh sulfates, surfactants, and petrochemicals to make those bubbles last much longer and foam as much as they do.  For dishes and other things with heavy amounts of grease on them, this is great.  The hydrophobic end of soap molecules may shun water, but they conveniently attach easily to grease.  When they attach themselves to the grease, the grease particles are surrounded by other soap molecules and wash away.  For your skin, this is not great at all.  Sulfates strip your skin of its natural moisture and clog pores. 

As in all of our products, our soap only uses whole oils that gently clean, nourish, and put essential moisture back into your skin.

Too many of us naturally equate bubbles with cleanliness.  More bubbles means more effective, right? 

Wrong! Especially when it comes to skin care. I highly doubt you are in need of a super-duper, grease-fighting detergent that is worthy of a cast iron skillet for your body. 

Take care of your skin! Put moisture into it! 

Our soap will lather, just maybe not the same way you are used to with added surfactants.  I heard an awesome metaphor: “It’s like baking a cake – if a recipe calls for plain flour, you wouldn’t bother adding self-rising flour.” The natural stuff will do it’s job!  Remember that extra bubbles are just a trivial side effect.
