This present invention provides a process for keratin hydrolysis by means of microbiological and/or enzymatic processes. In particular, the keratin is derived from feathers of animals, such as chicken and are submitted to hydrolysis by a strain of Bacillus sp.
I brought this to try on my locs that have been being dyed for two years. I haven't noticed that my locs are any softer, but the curls in my new growth were tight and shiny and my hair held on to water during my entire retwist (which has never happened).
your skin, hair, and even your fingernails is the same material: keratin. AC Keratin Hydrolysate 30 PF is an aqueous solution derived from sheep wool that is an ideal ingredient where conditioning benefits are desired. Keratin is a structural protein that does not soften in hot or cold water and is not susceptible to proteolysis.
Keratin is a highly specialized fibrous protein, which is found in hair, feathers, wool and nails. Keratin is distinct from other proteins in that it is rich in cysteine (a sulfur-containing amino acid) giving keratin a unique strength and protective quality. Derived from sheep's wool. pH value: 5.0-5.8. Contains 20-23% of protein.
Wool keratin hydrolysis with total solubilisation was achieved at pilot level. • Alkaline and alkaline-enzymatic keratin hydrolysates have specific properties. • FTIR-ATR, 13 C-NMR analyses confirm antimicrobial or bioactive components. • Alkaline keratin hydrolysates can be reintegrated in ecological agriculture.
Comparison with other protein hydrolysates aimed for fertilizer suggests that keratin degradation products, obtained by enzymatic hydrolysis, have potential to be used for foliar fertilization, alone or in a combination with another complementary hydrolysate of a different source, such as skin or plant proteins.
Summary. The goal of the protocol is to prepare keratin hydrolysate from chicken feathers by alkaline-enzymatic hydrolysis and to test whether adding keratin hydrolysate into a cosmetics ointment base improves skin barrier function (heightening hydration and diminishing transepidermal water loss).
Results. Keratin peptides were obtained by enzymatic hydrolysis of keratinases using Bacillus subtilis AMR. The microorganism was grown on a feather medium, pH 8.0 (1% feathers) and supplemented with 0.01% of yeast extract, for 5 days, at 28°C with agitation.

The present invention relates to methods and uses of a combination a protease and a non-sulphur containing surfactant in the degradation of keratin and subsequent uses of the keratin hydrolysate produced. BACKGROUND OF THE INVENTION. Keratin is the collective name for a family of tough proteins which are found in a number of structures.
Optimization of the process of enzymatic hydrolysis of keratin-containing stock aimed at obtaining hydrolysates of high biological value has been performed. The increasing of the stock/water weight...
hair is composed of a protein known as keratin, and are trying to rebuild and condition hair using this as a basic building block. Oleo Phytokera-tin™ SH allows the consumer to get all the benefits from keratin amino acids, but from a plant source. A study was performed to assess the effects of Phytokeratin™ PF Protein
FSS Plant Keratin OS is a vegetable derived alternative to animal hydrolyzed keratin. FSS Plant Keratin OS is an oil soluble product designed to help lock in moisture when applied to the hair and skin and is suitable for many formulations and skin types. This complex is an ideal ingredient for both rinse-off and leave in skin and hair care ...
Provide a more comprehensive for plant nutrition. Amino acids and their derivatives and metal complexes prepared by hydrolysis of keratin have dual effects on crop germicidal, disease control and growth stimulation. They can be used as fungicides, insecticides, herbicides and plant growth promoters. Pharmaceutical
In order to prove the J. curcas seed oil hydrolysis, FTIR spectroscopy supported the FFA% by showing the main peaks and their functional groups of the J. curcas seed oil. The comparison between J. curcas seed oil (a), hydrolysis at 1.00M (b) and at 1.75M of ethanolic KOH concentration (c), FTIR spectra is shown in Figure Figure6. 6.

Hydrolysis of vegetable oils and fats is an endothermic reaction ().The extent of hydrolysis increases with an increase in temperature. Additionally, the miscibility of water in lipid increases at high temperatures and pressures, thereby enhancing the rate of the hydrolysis reaction.
The optimal conditions for the preparation of keratin hydrolysates from keratin concentrations of 2–12% were attained by hydrolysis of wool and feathers for 6–9 min at boil.
Hydrolyzed Keratin for good hair 1.BRC,KOSHER,HALAL,ISO22000. 2.The hydrolyzed keratin is made from wool and other keratin collagen, processed by enzymatic hydrolysis technology into small molecular weight collagen peptide. 3.It's good for skin's compatibility and moisture, easily absorbed by hair and it stops the wound of the hair.
Hydrolysis, in chemistry and physiology, a double decomposition reaction with water as one of the reactants. Thus, if a compound is represented by the formula AB in which A and B are atoms or groups and water is represented by the formula HOH, the hydrolysis reaction may be represented by the
Keratin Hydrolysates, Process for Their Production and Cosmetic Composition Containing the Same Jun 30, 2008 This present invention provides a process for keratin hydrolysis by means of microbiological and/or enzymatic processes.
Abstract: Keratin hydrolysates are materials with wide spectrum of utilization. They can be prepared by many different methods of hydrolysis. This article describes wool treatment on keratin hydrolysates by combined two-steps alkali-enzymatic hydrolysis, where the wool was firstly disrupt in calcium hydroxide solution and
Hydrolyzed vegetable protein (HVP) products are foodstuffs obtained by protein hydrolysis and are used as ingredients with an authentic bouillon (broth) taste.. Regarding the production process, a distinction can be made between acid-hydrolyzed vegetable protein (aHVP), enzymatically produced HVP, and other seasonings, e.g., fermented soy sauce.
FSS Plant Keratin PF features hydrolyzed proteins derived from wheat, corn and soybeans, which combined can enhance moisturization and conditioning properties of a wide variety of skin care and hair care applications, in addition to, providing film forming and anti-irritant benefits to leave skin and hair hydrated and healthy
A supplier has reported that hydrolyzed hazelnut protein is produced by enzymatic hydrolysis. 10 Hydrolyzed Keratin Hydrolyzed keratin may be prepared from sheep's wool.11 The wool is first washed to remove soil and debris and then boiled to remove residual oils. Next, the wool is enzyme-hydrolyzed under mild conditions for 4-6 hours.
Hydrolysis of virgin coconut oil (VCO) had been carried out by using an immobilised lipase from Mucor miehei (Lipozyme) in a water-jacketed batch reactor. The kinetic of the hydrolysis was investigated by varying the parameters such as VCO concentration, enzyme loading, water content, and reaction temperature.
