01. KERATIN & GLYCEROL¶

Tools¶

magnetic stirrer, magnet, glass jar, weight, silicon mold / petri dish, spoon

Recipe II.¶

a.	b.	c.
Keratin powder	Distilled water	Glycerol
30 g	150 ml	20 g

Recipe II.¶

a.	b.	c.	d.
Keratin powder	Distilled water	Glycerol	Citric acid
30 g	150 ml	20 g	20 g

Process¶

Turn on the magnetic stirrer and place the glass jar with the distilled water on the top - turn on preheating.
Turn it on 300-500 rpm and slowly add keratin powder - spoon by spoon. Wait till it will dissolve and add more powder.
Let it stirr at 60-70'C for 6 h so all the ingredients will be well mixed.
Pour the mixed solution into a silicone mold or a petri dish and place it to the dehydrator at 50-60'C for 24 h.

Conlusion¶

In my case every test failed - skin formed on the surface but the rest was too liquid to get it out of the mold.

02. KERATIN & ALGINATE¶

Sodium Alginate¶

Description: Sodium alginate is a water-insoluble, gelatinous, cream-coloured substance that can be created through the addition of aqueous calcium chloride to aqueous sodium alginate. It has many applications in biology, but primarily known for its healing properties due to the compound's ability to encase enzymes in order to simulate new plant tissue.
Alginate is a naturally occurring anionic polymer typically obtained from brown seaweed due to its biocompatibility, low toxicity, relatively low cost, although the addition of divalent Ca2+ (calcium ions) results in mild gelation. Thus, considered a naturally occurring biomaterial.

03. KERATIN & GELATINE¶

Collagen is formed from three complex, fibrous long-chain proteins that twist into a helix. Collagen makes up your skin, bones, intestinal barrier, muscles, tendons, and joints. It acts like a glue for your entire body by keeping things pulled together and working properly.

Tools¶

magnetic stirrer, magnet, glass jar, weight, silicon mold / petri dish, spoon
