Do these two cancel each other out?

In summary: However, mixing it with handwash 1 won't make it less effective either. In summary, using both handwashes together will not cancel out the antibacterial effects of either one. Handwash 2 is specifically designed for antimicrobial purposes, so it would be the best option if that is your primary concern.

I'm wondering if by mixing these to handwashes, the antibacterial effect of both is cancelled.

Handwash 1: Aqua, Sodium Laureth Sulfate, cocamidopropyl betaine, sodium chloride, glycerin, polyquaternium-7, parfum, sodium benzoate, lactic acid, tetrasodium glutamate diacetate, benzotriazolyl dodecyl p-cresol, limonene, hexyl cinnamal, butylphenyl methylpropional, linalool, CI 42051

Handwash 2: Aqua, sodium laureth sulfate, sodium chloride, citric acid, cocamidopropyl betaine, sodium benzoate, cocamide DEA, disodium EDTA, glycerin, PEG-7 glyceryl cocoate, chamomilla recutita flower extract, methylchloroisothiazolinone, methylisothiazolinone, potassium sorbate

Any idea?

Thanks

In both cases, the main antibacterial is sodium benzoate. They won't interfere with each other.
The second handwash has methylchloroisothiazolinone, methylisothiazolinone, and potassium sorbate. It is unlikely that anything in the first handwash would interfere with these, but I don't know.

Here's the ingredients for the first one:

Aqua: water
Sodium Laureth Sulfate: a soap and surfactant
cocamidopropyl betaine: a natural mix, a surfactant
Sodium Chloride: salt
glycerin: probably included to provide a sweet scent
polyquaternium-7: antistatic or "fabric softener"
parfum: fragrance
sodium benzoate: preservative, this is your first antibacterial agent, it requires an acid environment to be effective
lactic acid: and here's you acid environment
tetrasodium glutamate diacetate: preservative booster (antibacterial)
benzotriazolyl dodecyl p-cresol: protects this mixture from UV
limonene: orange scent
hexyl cinnamal: fragrance
butylphenyl methylpropional, fragrance
linalool, fragrance
CI 42051: blue coloring

Additional ingredients in second one:
citric acid: provides acid environment and perhaps fragrance
cocamide DEA: foaming agent
disodium EDTA: water softener
PEG-7 glyceryl cocoate: skin conditioner
chamomilla recutita flower extract: fragrance
methylchloroisothiazolinone: antibacterial
methylisothiazolinone: antibacterial
potassium sorbate: antibacterial

Wow - thank you so much for that detailed reply! I'm pleased that you've explained what the different ingredients do - always wanted to know that!

So, it looks like handwash 1 wouldn't be weakened by handwash 2, but it's possible that handwash 2 is weakened by handwash 1. Have I got that right?

It is very unlikely that either will interfere with the other. But if you are looking for an antimicrobial handwash, stick with handwash 2; it was specifically developed for that. Mixing it with handwash 1 won't make it more antimicrobial.
 

1. Can two opposite forces cancel each other out?

Yes, two opposite forces can cancel each other out. This phenomenon is known as equilibrium, where the resulting net force is equal to zero.

2. How do you determine if two forces will cancel each other out?

To determine if two forces will cancel each other out, you need to compare their magnitudes and directions. If they have the same magnitude but opposite direction, they will cancel each other out.

3. Can two negative numbers cancel each other out?

Yes, two negative numbers can cancel each other out. This is known as additive inverse, where the sum of two numbers with opposite signs is equal to zero.

4. What happens when two opposite forces cancel each other out?

When two opposite forces cancel each other out, the resulting object will experience a state of balance or rest. This is because the net force acting on the object is equal to zero.

5. Is it possible for two forces to partially cancel each other out?

Yes, it is possible for two forces to partially cancel each other out. This happens when the forces have different magnitudes and directions, resulting in a net force that is not equal to zero.
