Beldi soap: a professional specification guide

Moroccan black soap, known as savon beldi or savon noir, is bought by spas, hotel groups, contract manufacturers and body-care brands for very different purposes. Two buyers can use the same product name and mean two different specifications. This guide sets out the questions a professional buyer should answer before requesting a quotation, so that samples can be compared on a like-for-like basis.

Start by defining the intended application

Write down where the product will be used and by whom: a therapist-applied hammam or spa protocol, a retail or amenity body-care product, a component in a formulation, or an internal evaluation before a wider decision. The application determines almost every other line in the brief, including texture, packaging, labelling requirements and the documentation a buyer will need to accept the product.

Composition, preparation and INCI questions

Ask each candidate source, in writing, what the oil base is, how the soap is prepared, what the resulting INCI declaration looks like, whether anything is added for scent, colour, preservation or viscosity, and how the finished product is stored before dispatch. Ask what varies between production runs. Answers should be attributed to a named product from a named supplier rather than to a category, because preparation practice differs from producer to producer.

Texture and sensory criteria

Define the sensory outcome you are buying against: paste consistency at ambient and at working temperature, spreadability, colour, odour profile and rinse behaviour. Record these as acceptance criteria before samples arrive. Sensory criteria written after tasting the first sample tend to describe that sample rather than the requirement.

Format and packaging

State the evaluation quantity, the pilot quantity and the eventual working quantity separately, along with the container type, fill weight, closure, labelling language and any artwork or regulatory marking you need. Note whether repacking is acceptable and who would carry it out. Formats are assessed per supplier and brief; bulk or packed options are not guaranteed.

Documentation to request

List the documents required for your own compliance file, for example composition or INCI documentation, safety data, origin information and any lot-level paperwork your registration or auditing process depends on. Ask which of these a supplier can provide for the exact product and lot being offered, and treat any gap as an open item to resolve rather than an assumption. Al Mamlaka confirms what is available for the selected product, supplier and lot, and identifies what is missing.

How to compare samples

Request samples of the product as it would actually be supplied rather than a reference presentation, label them blind where possible, and evaluate them against the criteria you wrote in advance. Keep quantity, storage and elapsed time consistent across samples, involve the people who will use the product, and record results in a single comparison sheet. Where a sensory or performance difference matters commercially, repeat the evaluation before concluding.

What to include in the brief

A workable brief states the intended application, the composition and preparation requirements, the sensory criteria, format and packaging, documentation requirements, evaluation and pilot quantities, destination, and any timing constraint. With those defined, sources and formats can be assessed against the requirement instead of against a product description.
