These pure soap flakes contain no unnecessary chemicals and are gentle enough for both hand washing and machine washing, making them a dependable choice for everyday laundry.
Made using cold-saponified Coconut Oil and Sunflower Seed Oil, they form a true vegetable soap that cleans effectively while remaining kind to fabrics and skin. Lightly fragranced with pure Patchouli essential oil (Pogostemon cablin), this is one of the most natural and characterful laundry detergents you can buy.
Patchouli essential oil has a long history of use in textile care. Traditionally, it was used to protect fine Indian shawls during transport, where its distinctive aroma helped repel moths and insects — a property still valued today. It is also known for its natural deodorising, antibacterial, and antifungal qualities, making it particularly suitable for everyday clothing, heavier fabrics, and stored garments.
With its warm, earthy scent, Patchouli leaves laundry subtly fragranced rather than perfumed, offering a grounding, reassuring aroma that feels timeless and comforting.
Produced using the pure artisanal tradition of cold saponification and certified organic by Ecocert, these soap flakes combine traditional knowledge with modern ingredient transparency.
This laundry soap is based on a true soap formulation, created by cold-saponifying organic vegetable oils with sodium hydroxide. During this traditional process, the alkali is fully transformed, leaving behind a mild yet effective soap enriched with naturally occurring glycerin.
Organic Sunflower Oil supports fabric care and helps preserve fibres
Organic Coconut Oil delivers effective cleansing power for dirt and odours
Naturally retained glycerin helps prevent fabrics from becoming dry or brittle
Patchouli essential oil provides fragrance alongside deodorising and traditionally protective properties
The formula cleans by binding to dirt and allowing it to rinse away naturally, without synthetic detergents, enzymes, or optical brighteners.
Natural Laundry Boosters (Optional)
For whites or heavy-duty cleaning:
Add 1 tablespoon of sodium percarbonate to the detergent drawer along with your soap mixture. This acts as a natural whitener and provides additional deodorising and antibacterial support.
As a natural fabric softener:
Add 100–200ml of white vinegar to the fabric softener compartment. This softens towels and fabrics naturally and, when used regularly, helps prevent limescale build-up in your machine.

Contains Patchouli essential oil (Pogostemon cablin), a naturally occurring fragrance ingredient. Free from synthetic fragrance, dyes, enzymes, optical brighteners, and preservatives.
Those with very sensitive skin or fragrance sensitivities are advised to test on a small wash before regular use.
Each pack provides approximately 200 washes, making it an exceptionally economical and low-waste laundry solution.
This impressive longevity comes from the highly concentrated nature of true soap flakes. With no added fillers, thickeners, or synthetic bulking agents, only a small amount is needed per wash. The flakes dissolve fully and work efficiently, even in cooler washes and short cycles.
Fewer washes per pack also means:
Less packaging over time
Fewer repeat purchases
Lower transport and environmental impact
It’s a clear example of how traditional formulations often outperform modern detergents, delivering both performance and long-term value without compromise.

Maison Berthe Guilhem is an artisan family savonnerie that hand make all their soaps.
Berthe Guilhem made her first goat's milk soaps in 1956 alongside ointments and the famous gardener's balm. Initially she made all the products for herself, her children, friends and neighbours.
Today Marc & Jean-Luc, Berthe Guilhem's grandsons, and their families, continue using her original methodology and recipes that adhere to strict and uncompromising respect for their formulations and for the environment.
Their believe "you can work in a human-sized laboratory, maintain an artisanal identity while manufacturing effective, efficient and state-of-the-art organic cosmetic products."
Marc Guilhem, grandson of Berthe Guilhem, is also a former student of the European Center for Applied Naturopathy
Creamy and durable, our soaps are made by hand
Maison Berthe Guilhem use a cold saponification method; The combination of organic vegetable oils and organic goat's milk in an unaltered state gives them exceptional results. Always cold, the formulation is kneaded before being vigorously pressed and molded. The soaps are hand cut and stamped after several weeks of drying. Their lifespan is extended due to their low percentage of humidity (8 to 10%).
100% natural ingredients
They make all their own infusions, decoctions, macerations and mother tinctures ensuring they make the best use of their natural properties.
What is cold saponification?
Cold saponification is the result of a mixture of soda in water, then later in oil. This manufacturing method is called Cold Saponification because it does not use the heat like traditional Savon de Marseille: The heat is naturally induced by the addition of soda to the water and then to the Oil that raises the temperature of the mixture until it blends. Once this process has occurred the ‘soap’ is left to dry for several weeks before Organic Goats Milk and other ingredients for example Avocado Oil, Shea Butter or Essential Oils are added.
Certified organic natural artisanal know-how
The Berthe Guilhem laboratory is certified to the National Agency for the Safety of Medicines and Health Products (A.N.S.M.). The majority of products are labeled COSMEBIO and certified organic QUALITÉ FRANCE and COSMECERT. At each stage of their manufacture, they are subject to dermatological tests and quality controls proving their safety. These tests, carried out by an independent laboratory, are done on healthy volunteers.
Berthe Guilhem: highly organic products
Maison Berthe Guilhem ensures the quality of its products and their composition. They all contain between 55% and 100% organic ingredients, which is very important compared to the 20% needed to obtain an organic certification!

I bought the trial pack to start and was impressed. It seems to wash well and I like the fact there isn't lots of nasty ingredients. I am converted to this now !
Am pleasantly surprised at the cleaning power of the laundry soap flakes! Guilt free washing for a change. No nasty chemicals or unneccessary additives. Scent not as strong as I would have liked but will definitely buy again.
Easy to make up and use. Smells divine and very economical
Live the smell with clothes
We love these soap flakes. The smell is great, washes well and lasts forever. Very economical. Second purchase and won't be the last.
