We do not use any synthetic detergent agents, fillers, synthetic preservatives, chemicals, fragrance oils, or other scientifically proven and well recognised synthetic ingredients known as endocrine disruptors, neurotoxins or immunotoxins.
Our soap is made using methods dating back centuries and know as castile soap. It is made by hand, in small batches (up to 200L for liquids and 100 bars for hard bar at one time). This means there can be very minor variations in colour and the soap itself, however we strive for consistency each time.
We recognise any ingredient used in any product can however be an irritant, allergen, or cause problems for some people, and we suggest when changing to any product, ours or otherwise, caution is used.
Our products are safe on the environment and in septic systems. We are constantly researching and staying informed to ensure our products continue to meet the highest health and safety protocols, and also do the job they are intended to do - properly!
All proper Soaps are made using Sodium Hydroxide or Potassium Hydroxide. This saponifies during the process with the oils and water and by the time your soap is a hard bar or finished liquid soap, the Sodium or Potassium Hydroxide has evaporated from the soap and has turned into bi products including glycerine.
Another name for the combination of Sodium or Potassium Hydroxide and Water is called Lye, or you will see it as "Saponified Oils".
A soap made without lye is made with either animal products like Tallow or a combination of detergents, surfactants and emollients from laboratory produced synthetics. Technically, it does not therefore meet the definition of soap.
People are sometimes worried about Sodium and Potassium Hydroxide. In a properly made soap it is completely absent from the soap once you buy it. We are actually not required to disclose lye, or sodium hydroxide as an ingredient because it is no longer in the finished product, however Kahuku believes in full disclosure.
Sodium Hydroxide can actually be found in food, as it is used in curing processes, and also adds "crunch" to some products like Pretzels.
Kahuku Products are free from animal products, detergents, and synthetically produced ingredients.
