Liquid Castile Soap: Easy Recipe and Ways to Use It

Liquid Castile Soap: Easy Recipe and Ways to Use It

The move to reduce the amount of wastage and pollutants that could harm the environment has become so universally accepted and expected that many people have gradually adopted new practices for the new normal. A few companies in recent years have also slowly joined the fray, offering products that are hoped to lessen the potential damages to the climate such as green cars, air conditioners with less freon, solar lights among other things.

Even cosmetic and personal care companies now offer products with less harsh chemicals or at least not leave residues that would negatively affect the ph level of the water. For example, micro-beads which used to be a major compound in astringents or body wash are no longer allowed. Household products that use heavy substances were also slowly taken out of the market.

For this reason, many people have started patronizing cosmetics and beauty products that would at least ensure that no compounds would be released to the environment and at the same time, protect their health and skin. Aside from this, some have also opted to make their own or more popularly known as Do-it-Yourself for them to have better control on the type of ingredients and volume that they would consume.

Making your own soap is one popular DIY that a lot of environmentally conscious people have started to adopt. And one type that has gradually attracted a lot of people is Castile Soap.

The Versatility of Castile Soap

So what is Castile soap? From the name itself, this soap is named after a northern region in Spain where the soap was popularised. However, it was on the Mediterranean coast when Castile soap first became known.

In the US and Europe, a lot of pharmacies and apothecaries carry Castile soap both in bar and liquid form. You can also find some brands available in select large chain supermarkets.

Basically, what sets Castile soap apart from other soaps is its use of vegetable oils instead of harsh synthetic compounds. Olive oil, which is aplenty in southern Europe and Mediterranean areas, is its main ingredient. In recent years, however, other vegetable-based oils such as coconut oil, walnut oil, castor oil have replaced olive oil, or at least mixed with olive oil to produce more moisture and anti-bacterial properties.

The versatility of Castile is unchallenged because you can hardly find a soap that not is only good for the body, but has a lot of purposes such as for cleaning the house, washing dirty laundry and for grooming pets.

These and not leaving harsh residues in the water that can hurt the environment.

Some Uses of Castile Soap

Since this soap makes use of natural oils that are gentle on the skin, Castile soap can be used for:

Personal Hygiene

  • Face wash: Since a few of its main ingredients are mild and have pimple fighting components, Castile soap is perfect for cleansing the face.
  • Body wash: Its mild ingredients and bacteria-fighting formula make it also a perfect soap to wash away dirt from the body without drying the skin.
  • Shampoo: From head to toe, Castile soap can also be used as a shampoo. Just mix about one tablespoon of this soap with about a cup of water and lather.
  • Wound cleaner: Its antibacterial properties also make it as an alternative wound cleaning agent. Just use like normal soap and then rinse off with clean water.
  • Baby soap: Due to its mild and moisture-rich properties, Castile soap is safe enough for baby’s delicate skin.
  • Shaving cream: Surprisingly, you can also use this as an alternative for commercial shaving creams and gels since it’s packed with moisture that can easily soften body hairs, allowing the razor to glide smoothly. Lather it on your face (for men), legs and armpits and glide your razor.

Other Uses

Vegetable cleaner

Again, because it is vegetable oil-based, Castile soap can also double as vegetable and fruit cleaner without affecting the taste. Just soak them in water with a drop of liquid castile oil.

Dog shampoo

Dog lovers will definitely love the versatility of this soap as it can also be used to clean and wash away all the dirt from your dog’s body, even making your dog’s coat and fur shiny.

Sinus decongestant

We all know how irritating it is when we have a clogged nose. Castile can help ease your breathing by dropping a few drops of this on a bowl of hot water, then adding a few mixtures of eucalyptus or peppermint oil. Lean over the water, covering both your head and the bowl to trap the steam. Inhale and relax until your breathing eases.

Bug spray

While castile soap won’t kill the ants or bug, it’ll deter them from wreaking havoc on your plants. Mix a portion of water with 1 tablespoon of Castile liquid soap around the plant. Don’t spray the plant as it could make them wilt.

Floor cleaner

Its natural and antibacterial properties also make it an ideal floor cleaner. With a bucket of water, add two tablespoons to create a cleaning mixture. Soak your mop and then mop away the dirt and grime.

Window cleaner

It may not be as tough compared to commercial cleaners, but this soap can also wipe away window stains and soot. Add one to two tablespoons of castile soap to a quarter of water. Place the mixture on a clean spray bottle. Spray directly to the window; leave the liquid for a few minutes then wipe away using a cloth or sponge.

Kitchen and bathroom scrub

The thought may seem a little strange but Castile soap is also recommended for scrubbing away the accumulated dirt and oil in the kitchen and bathroom. Just create a mixture of the cleaning scrub with 1 cup of Castile soap and three cups of water. To make it more effective, add some baking soda. Put the mixture into a spray bottle, spray the directly to the desired area then wipe off the dirt.
