Spirulina powder is a nutrient-rich blue-green algae (INCI: Spirulina Platensis) used mainly in cosmetic formulations for skin and hair. Azlok's spirulina is cosmetic-grade, which means it is processed for topical use in face masks, hair packs and DIY personal-care products rather than as a food supplement.
What is spirulina powder?
Spirulina is a microalgae that grows in freshwater and dries into a deep blue-green powder. It carries proteins, B-complex vitamins, minerals and antioxidants, which is why it has become a favourite ingredient among small skincare brands and home formulators. In cosmetics, it is valued for helping draw out impurities and refresh tired-looking skin.
Common uses in skincare and haircare
- Detoxifying face masks: Spirulina helps lift away excess oil, dust and surface impurities, making it useful for dull or oily skin.
- Rejuvenating packs: Its antioxidant content makes it a popular add-in for weekly "glow" masks.
- Hair packs: Blended into hair masks, it adds nutrients that condition the scalp and strands.
- Soap and formulation colour: A pinch gives cold-process soaps and bath products a natural green tint.
How to use spirulina powder
A little goes a long way, so start with small quantities and adjust.
- Simple face mask: Mix 1 teaspoon spirulina powder with enough water, rose water or honey to make a smooth paste. Apply an even layer, leave for 10-15 minutes, then rinse with lukewarm water.
- Clay-and-spirulina mask: Combine 1 teaspoon multani mitti with half a teaspoon spirulina and a little water for a deeper cleanse.
- Hair pack: Blend 1-2 teaspoons into your usual hair mask base (curd, aloe vera gel or a conditioner) and apply to scalp and lengths for 20 minutes before washing off.
- Soap colourant: Add roughly a quarter to half teaspoon per 500 g of soap base, adjusting to the shade you want.
Spirulina stains, so mix in a bowl you don't mind tinting and wash brushes promptly.
Tips and safety notes
- Patch-test first: Apply a small amount on your inner arm and wait 24 hours before using on the face.
- This grade is for external use: Cosmetic-grade spirulina is meant for topical products, not for eating. Do not ingest it.
- Keep away from children and avoid contact with eyes.
- Mix fresh: Prepare masks just before use rather than storing wet mixtures, which can spoil.
- Manage the colour: Rinse thoroughly; the green tint washes off skin easily but can mark light fabrics and grout.
Buying and storage
Azlok offers spirulina powder from 100 g packs up to 20 kg, so home hobbyists and small businesses can both find a suitable size. Pricing starts at ₹299, and larger packs suit soap makers and personal-care brands buying in bulk.
- Store in a cool, dry place, away from direct sunlight and moisture.
- Keep the pack tightly sealed after each use; moisture causes clumping and shortens freshness.
- Shelf life is around 2 years when stored well.
- For formulation and compliance records, ask for the COA and MSDS.
Good spirulina powder has a fine texture, a deep green colour and an earthy, seaweed-like smell. If the powder smells off or has changed colour, it is best not to use it.
FAQ
Can I eat Azlok spirulina powder?
No. This is cosmetic-grade spirulina intended for external, topical use in skincare and haircare formulations. It is not sold as a food or supplement, so please do not ingest it.
How often can I use a spirulina face mask?
For most skin types, once or twice a week is a good starting point. Always patch-test first and reduce frequency if your skin feels dry or irritated.
Will spirulina stain my skin?
It can leave a light green tint while on the skin, but this rinses off easily with lukewarm water. Be more careful with clothes, towels and light surfaces.
What is the shelf life and how should I store it?
Spirulina powder keeps for about 2 years when stored in a cool, dry place in a tightly sealed pack, away from sunlight and moisture.
Which pack size should I choose?
For occasional home use, the 100 g or 500 g pack is plenty. Soap makers and small personal-care brands often prefer the 1 kg and larger bulk packs.
