Something I do is put a drop or two of dish soap in a normal 500ml water bottle and add water to create a concentrate. Then I pour about 100ml of that or so into a gallon of water.
If you ever run out of wetting agent, a good alternative is a few drops of washing up liquid - does same job.
Conventional wetting agents are usually alcohol or petroleum distillates, such as polyacrylamides. Polyacrylamides are commonly used on an industrial scale in irrigation water to (in theory) improve the absorption of water by soils and to reduce soil erosion.
Dish soap is fine--I have used it many times. I use about a full 20 ounce bottle in my 400 gallon tank. In recent years I have been using laundry detergent--wets well and smells nice. A tablespoon is slightly too much for a hand sprayer--a good squirt or a teaspoon is more like it.
You can buy a wetting agent for hydrophobic soil at most garden centres or make one at home using agar (powdered kelp). It's also possible to use diluted dishwashing liquid or dishwater/laundry water as a soil wetter because the surfactants in the detergent break surface tension in water like wetting agents do.
In most domestic homeowner situations, the easiest and most accessible surfactant to use is dishwashing liquid. As mentioned earlier, soap contains the surfactant Sodium stearate. Liquid dishwashing liquid can be added to a tank mix of the herbicide or pesticide being applied and mixed with water.
The active ingredient is usually a 'surfactant', which behaves in the same way as a detergent: a long molecule that contains a 'tail' and a hydrophilic 'head'. The head can be positively charged (cationic), negatively charged (anionic) or carry no charge (non-ionic).
BestWet is a liquid non-ionic wetting agent that has been developed for use on amenity grass, golf greens and tees. It is designed to help prevent the occurrence of Localised Dry Patch (LDP) which prevents healthy grass growth.
Unlike fertilisers that can cause toxicity if applied too frequently or in too large an amount, wetting agents present no such risk. While they won't cause in problems, applying them too frequently is a waste of money – once they have done their job there is nothing more that can be achieved.
The hydrophilic–lipophilic balance (HLB) value of wetting agents is generally 7–9. Methylcellulose, acacia, pectin, surfactant–sodium lauryl sulfate, polysorbate 80, poloxamers, Pluronics, etc., are some of the wetting agents used in liquid formulations (Mahato and Narang, 2017).
Adding dish detergent to your weed killer could tear apart the molecular structure of the chemical, making it less effective in killing weeds. It is possible that adding a dish detergent to your weed killer as a surfactant could increase the adhesion of the chemical to the leaf of the weed.
In some cases, they are used as makeshift wetting agents in various applications like painting or gardening. However, detergents may contain additional chemicals like fragrances, dyes, or harsh agents that could interfere with the intended purpose.
You can make your own wetting agent using the same soap you use on your sponge, your hands and dishes.
The simplest way to do this is to add extra organic matter such as well-rotted manure or compost, digging in a good amount to fix the immediate issue, and continuing to add smaller amounts throughout the year to maintain the soil's condition.
With an enhanced SAR, the plant has improved resistance to environmental stresses such as drought, cold, heat, excess humidity and heavy metal toxicity. Aloe Vera has saponins, which make it an effective wetting agent in root drenches and surfactant, or carrier in foliage applications.
Another way of making your own wetting agent is to add 3 drops of detergent to 5 litres of water. Make sure that you are using a plant-based detergent that does not have a fragrance as fragrances are often toxic.
Desmopressin link (DDAVP) is often the first choice of medicine for bedwetting. This medicine slows the amount of urine your child's body makes overnight, so the bladder doesn't overfill and leak. Desmopressin can work well, but bedwetting often returns when a child stops taking the medicine.
Glycerine is also a humectant (wetting agent), which promotes scalp hydration, disciplines the hair and improves curl definition.
Contains the active ingredient Nonyl Phenol and Alcohol Ethoxylates. Is a spray additive that is suitable for herbicides, insecticides and fungicides.
"Soap is a surfactant. Shampoo contains surfactant and detergents contain surfactants. Baking soda does not."
Baby shampoo tends to use milder foaming agents and by using less harsh chemicals and cleansers they avoid irritating sensitive skin and eyes. Baby shampoos shy away from sulfate based cleansers or surfactants and instead rely on amphoteric surfactants that can clean, while also preventing irritation.
