There are two different families of clays: terrestrial clay and marine clay. One comes from rocks, the other comes from the sea.
What is Earth Clay?
Earth clay is a sedimentary rock composed primarily of silica, but it also contains aluminum, magnesium, calcium, iron, phosphorus, sodium, potassium, copper, zinc, selenium, cobalt, manganese, and lime. It is found several meters underground. Depending on its composition, clays can come in different colors (green, white, pink, blue) and it is found in several forms: powder, crushed or ready to use.
Green clay: rich in oxidized iron and organic matter, it is the best known and most used clay, but also the most active
White clay (or kaolin) is composed of aluminum silicates. Its lack of minerals and its neutral pH make it a very soft clay.
Red clay : it owes its color to the absence of organic matter combined with the presence of highly oxidized iron
Pink clay: it is a mixture of white clay and red clay, so it combines their properties
Yellow clay : it gets its luminous color from the copper and zinc that compose it
Blue clay : it is rarer than the others and owes its color to its high silica content
Violet clay: this clay is a mixture of white kaolin clay and mineral pigments, it is very rich in silica and mineral salts
Rhassoul: clay from Morocco where it is commonly used in hammams for skin and hair care
So what is the difference with the marine clay used in Perlucine products?
Marine Clay used in Perlucine products comes from the south of Brittany, in the village of Moutiers-en-Retz, The deposit of marine alluvium has formed a clay whose average thickness is about 5 to 7 meters with, in places, pits of about twenty meters. The clay is harvested and filtered in order to get rid of its sandy or stony particles. The latter can thus be used in an institute, after having been possibly enriched by the addition of essential oils or plant extracts. This clay can also be micronized in order to obtain a fine powder, which can thus be used for body wraps, by mixing it with water, but also in formulation as a remineralizing treatment or as a nutritional supplement. The clay of Moutiers-en-Retz, rich in minerals and trace elements,
What are the benefits of Marine Clay?
Rich in negative ions from disintegrated marine flora and fauna, sea clay is known for its remineralizing and detoxifying action. Mixed with seawater and applied as a poultice to targeted areas of the body, the mud effectively combats rheumatism and certain dermatological disorders.
Cellular regeneration: the covering power of the Moutiers Marine Clay, probably thanks to its aluminum silicate content, by forming a protective film, stimulates tissue renewal
Remineralising: thanks to the presence of minerals in the marine clay
Absorbent, it eliminates toxins and gently cleanses acne-prone skin
Marine clay is used in Perlucin toothpaste, as well as in body and face mask.
