Collection: Natural Castile Washes & Cleansers For Mature Skin | Australia Made

Castile wash is a traditional plant-based cleanser that originated in the Mediterranean, named after the Castile region of Spain where soapmaking was historically centred. It is made entirely from vegetable oils such as olive oil, with no animal fats, making it vegan and biodegradable. Its cleansing action comes from soap molecules that have one end attracted to water and the other to oils and dirt, allowing it to lift away grime when rinsed.

Because it is free from sulphates and harsh synthetic detergents, Castile wash provides a gentle yet effective cleanse that is well suited to sensitive and dry skin. Its plant-based nature also makes it non-corrosive and versatile, suitable for use on the body and in a range of everyday cleaning applications.

Yes! Castile wash is often well suited to sensitive skin because it is made from simple plant oils and is free from sulphates, synthetic detergents, and harsh foaming agents that can commonly trigger dryness or irritation. Its gentle cleansing action helps remove dirt and impurities without disrupting the skin’s natural protective barrier.

Because it relies on naturally derived soap from oils such as olive oil, it tends to be less stripping than conventional body washes, making it a common choice for those with reactive, dry, or easily irritated skin. Many people also prefer it for everyday use because it supports a clean feel without leaving skin tight or overly dry.

Castile wash is a highly effective yet gentle cleanser, well suited to sensitive skin due to its simple, plant-based formulation. It is free from sulphates and harsh synthetic detergents, helping to cleanse without stripping the skin’s natural oils or causing irritation. Because it is highly concentrated, only a small amount is needed per use, making it both economical and long-lasting while also helping to reduce overall product waste over time.

Sulphates are a group of cleansing agents commonly used in body washes, shampoos and household cleaners to create foam and help lift away oil and dirt. The most common ones are sodium lauryl sulphate (SLS) and sodium laureth sulphate (SLES).

They are not inherently “toxic”, but they can be too strong for some skin types. Because sulphates are highly effective degreasers, they can also strip away the skin’s natural oils, which may leave the skin feeling dry, tight, or irritated—particularly in people with sensitive, dry, or eczema-prone skin.

For this reason, many people choose sulphate-free cleansers, such as traditional castile washes, which use plant-based oils instead to gently cleanse without disrupting the skin’s natural moisture barrier.

Yes! Castile wash can be used as a wonderful shampoo for many hair types, particularly for those looking to avoid sulphates and synthetic cleansing agents. Because it is made from plant-based oils such as olive oil, it cleanses the scalp without the harsh degreasing effect of conventional shampoos, helping maintain natural moisture balance.

It is especially popular with people seeking a simpler, low-irritant hair care routine. Depending on hair type, it may feel less foamy than conventional shampoos, but it still effectively removes dirt and excess oil while remaining gentle on the scalp. Some users choose to follow with a light conditioner or acidic rinse to support softness and manageability.
