Dunaliella salina is a halotolerant microalgae cultivated for its exceptionally high beta-carotene content. It is supplied as a dried powder and used across food, cosmetics, feed, and agriculture industries.
Dunaliella salina has a high content of carotenoids and the vital substance beta-carotene. Beta-carotene is the precursor of vitamin A and therefore essential for human health and a protected skin.

Dunaliella salina is a unicellular photosynthetic microalgae naturally occurring in hypersaline environments such as salt evaporation ponds, salt lakes, and coastal saline water bodies [1, 2]. It has been identified in environments including highly saline inland lakes and salt flats across multiple continents [2].
The organism accumulates beta-carotene as a physiological response to environmental stressors including high light intensity, elevated salinity, and temperature variation [3, 4]. This natural accumulation mechanism makes it a primary commercial source of natural beta-carotene.
Beta-carotene concentration in the biomass is influenced by cultivation conditions; production parameters are adjusted to achieve the desired carotenoid content [4].
We supply Dunaliella Salina in bulk for B2B buyers across the food supplement, feed, cosmetics, and agriculture sectors. Delivery times are available on request. Contact us to request a quote, discuss volume requirements, or obtain a product specification sheet.
Dunaliella salina is a unicellular halotolerant microalgae found in saltwater and hypersaline environments worldwide. It is commercially cultivated primarily as a natural source of beta-carotene and other carotenoids [1, 2].
It is used as a natural colouring and beta-carotene source in food ingredients, as an antioxidant and anti-aging active in cosmetics, as a nutrient-rich component in aquaculture feed, and as a functional ingredient in food supplements [3, 4, 5, 6, 7].
The organism produces and accumulates beta-carotene as a protective mechanism against environmental stressors such as intense light and high salinity. Under optimal cultivation conditions, this accumulation can reach commercially significant levels [4].
Dunaliella salina is used in the food, cosmetics, aquaculture feed, nutraceutical, and agriculture industries [3, 4, 5, 6, 7].
Beta-carotene functions as a provitamin A precursor and as an antioxidant capable of neutralising free radicals associated with cell damage. Research has also explored its anti-inflammatory properties and relevance to skin aging [3, 4, 9, 10].
It is cultivated in controlled or semi-controlled saline environments under sunlight or artificial light. Carotenoid content is influenced by cultivation parameters including salinity, light intensity, and temperature [4].
Yes. Its beta-carotene content, antioxidant activity, and skin-supportive compound profile make it relevant for use in cosmetic applications. It is important to verify regulatory compliance for the target market before formulating [5, 8, 9].
Yes. It is important to check local regulations before integrating Dunaliella salina into products intended for human consumption.
