Nautica Liquid Soap Base - COSMOS Organic is a ready-made organic liquid soap base designed for gentle cleansing and easy customisation. It offers a practical starting point for hand wash, face wash, body wash, and shampoo-style DIY projects, without the need to build a liquid soap from scratch. Because it is unfragranced, it can be left as is or personalised with suitable essential oils to suit your preferences. This is a fully formulated base that is suitable for most skin types, including sensitive skin.
♡ Why we love it: A good soap base makes DIY much more accessible, and this one keeps things simple without feeling limiting. It is especially useful when you want a clean, organic foundation that can be used as is or personalised with your own scent and style.
