Hydrolyzed keratin powder is a plant- and feather-derived protein that has been broken down into small fragments so it can be added to water-based hair and skin products. Because those fragments are smaller than whole keratin, they spread easily through a formula and help support the surface of hair and skin. Azlok supplies it as a fine white powder that dissolves in water, making it a straightforward ingredient for home and small-batch makers.
What is hydrolyzed keratin powder?
Keratin is the structural protein naturally found in hair, nails and skin. The raw keratin fibres for this ingredient are extracted from feathers, then put through enzymatic hydrolysis. This process splits the large protein molecule into shorter pieces by adding hydrogen and hydroxide bonds. The result is a smaller, water-soluble protein that behaves well in cosmetic formulas.
A few useful specifications at a glance:
- INCI name: Hydrolyzed keratin protein, butylene glycol, phenoxyethanol, ethylhexylglycerin

- Form and colour: White powder, mild odour
- Solubility: Soluble in water
- pH: 5.0–5.8
- Purity: 99%
- Shelf life: 24 months
Common uses
Hydrolyzed keratin is a versatile film-forming protein, which is why it appears in so many product types. It is popular in:
- Shampoos and conditioners
- Hair masks, serums and sprays
- Leave-in treatments and heat-protectant sprays
- Facial serums, moisturisers and creams
- Anti-ageing products, lotions and body butters
In hair products it is prized for its conditioning feel and its ability to leave a smooth surface. In skin products, it acts as a humectant-friendly protein that helps a formula feel softer on application.
How to use it in a formula
Because it is water-soluble, hydrolyzed keratin is added to the water phase of your product. A simple approach:
- Weigh your total batch and calculate your keratin at the usage rate you want (commonly around 1–5% of the total formula for leave-on and rinse-off products).
- Disperse the powder into your water phase and stir until fully dissolved.
- Combine with the rest of your formula as usual, keeping heat moderate — proteins prefer gentle handling rather than prolonged high heat.
- Always include a suitable broad-spectrum preservative in any water-containing product.
Start on the lower end of your usage range. Too much protein in a hair product can make strands feel stiff or straw-like, so balance it with conditioning and humectant ingredients. Check and adjust the final pH of hair and skin products to a skin-friendly range.
Tips and safety notes
This is a cosmetic raw ingredient meant for external application only. Please keep these points in mind:
- Do not ingest it, and do not use it on broken, irritated or diseased skin.
- Patch-test any new formula on a small area before regular use.
- Handle powders in a ventilated space and avoid inhaling fine dust; wear a mask if you are weighing large quantities.
- Keep out of reach of children and pets.
- Refer to the COA and MSDS for handling and specification details before scaling up.
Buying and storage
Azlok offers hydrolyzed keratin powder in sizes from 50 Gm and 100 Gm for hobby batches up to 500 Gm, 1 KG, 5 KG, 10 KG and 20 KG for small businesses and larger production runs. The 50 Gm pack starts at ₹349, which makes it easy to trial before committing to bulk.
For storage, keep the powder in a cool, dry place away from direct sunlight and humidity. Reseal the pack tightly after each use, since moisture can cause clumping. Stored well, it holds a shelf life of up to 24 months. Buying a smaller size first is sensible if you are still testing recipes, so your stock stays fresh.
FAQ
What does hydrolyzed keratin powder do in hair products?
It is a small, water-soluble protein that conditions and forms a smooth film on the hair surface. Because it is hydrolysed, its fragments are compact enough to work well within shampoos, conditioners, masks and sprays.
How much should I add to my formula?
A common range is about 1–5% of the total batch, depending on the product. Begin at the lower end and adjust, because too much protein can make hair feel stiff.
Is it soluble in water or oil?
It is soluble in water, so add it to the water phase of your formula and stir until fully dissolved.
Can I use it on my skin?
Yes, it is used in facial serums, moisturisers, creams and body butters for external application. Always patch-test first and avoid using it on broken or irritated skin.
Can I take it internally as a supplement?
No. This product is a cosmetic raw material meant only for external use. Do not ingest it.
