Promois

Hydrolyzed Proteins (Peptides) and their Derivatives

Promois is the trademark for peptides and their derivatives obtained through hydrolysis of natural proteins.

They are raw materials for cosmetics with an excellent conditioning effect that moisturizes, protects, and repairs skin and hair, and are gentle to human and friendly to the environment. It has different functions in every origin and derivative.

Classification by Protein Origin

The various proteins sources of Promois products are pea, soybean, wheat, rice, sesame, pearl shell, silk, keratin, collagen, fish collagen and milk.

  • Soybean

    Soybean

    Among plant-derived proteins, soybean especially gives softness and smoothness to the hair.

    1. Standard type
    2. Cationized type
    3. Acylated type
    4. Silylated type
  • Wheat

    Wheat

    Among plant-derived proteins, wheat especially gives softness to the hair.

    1. Standard type
    2. Cationized type
    3. Silylated type
  • Pea

    Pea; Botanical Keratin

    Among plant-derived proteins, pea especially gives body and stiffness to the hair.

    1. Standard type
  • Rice

    Rice; Botanical Silk

    Among plant-derived proteins, rice especially gives slippery smoothness to the hair.

    1. Standard type
  • Sesame

    Sesame

    Among plant-derived proteins, sesame especially gives strength to the hair.

    1. Silylated type
  • Pearl

    Pearl

    Pearl (Conchiolin) contains many small amino acids, therefore it forms smooth coating film and gives shine.

    1. Standard type
  • Silk

    Silk

    Fibroin contains many amino acids which form β-sheet structure, therefore it has good coating ability and gives gloss appearance and smooth texture. Sericin contains many amino acids having a hydroxyl group, which gives moisture and smooth texture.

    1. Standard type
    2. Cationized type
    3. Acylated type
    4. Ethyl esterified type
    5. Silylated type
  • Keratin

    Keratin

    Keratin peptide is a hydrolysate of keratin which is a main component of hair. It adsorbs to the hair highly and gives body and stiffness.

    1. Standard type
    2. Cationized type
    3. Acylated type
    4. Silylated type
  • Collagen

    Collagen

    Collagen contains many amino acids having a hydroxyl group, therefore it has an excellent moisturizing property and gives softness and smoothness to the hair.

    1. Standard type
    2. Cationized type
    3. Acylated type
    4. Silylated type
  • Fish Collagen

    Fish Collagen

    Fish collagen is suitable for not only hair care but also skin care due to its low odor and less color.

    1. Standard type
    2. Acylated type
    3. Silylated type
  • Milk

    Milk

    Milk (Casein) contains many acidic amino acids, therefore it gives an excellent moisturizing ability.

    1. Standard type
    2. Cationized type

Classification by chemical modifying

In addition to the normal peptides, the Promois series also include the peptide derivative series.
The peptide derivative series is a range of raw materials with special properties brought about by chemically modifying the peptide to make it suitable for incorporation into cosmetics.

  • Standard type

    A peptide obtained by hydrolysis of natural proteins. Different origins of protein have each efficacy, therefore you can choose most suitable one as you want.

    1. Soybean
    2. Wheat
    3. Pea
    4. Rice
    5. Pearl
    6. Silk
    7. Keratin
    8. Collagen
    9. Fish collagen
    10. Milk

  • Silylated type

    A derivative bonded with a silyl group. It protects and repairs hair, and improves its texture by a heat enhancing effect that results in the formulation of a film on the hair in response to heat from hair dryers or hair ironing.

    1. Soybean
    2. Wheat
    3. Sesame
    4. Silk
    5. Keratin
    6. Collagen
    7. Fish collagen
    Heat Active

    The heat active sites of SIG series react to heat and form a film on the hair surface, which improves hair strength.

  • Cationized type (Q/CAQ/SAQ series)

    A derivative bonded with a quaternary ammonium group in order to enhance the adsorption to the anionic damaged hair. It is suitable for incorporation into hair conditioner and treatment formulations.

    1. Soybean
    2. Wheat
    3. Silk
    4. Keratin
    5. Collagen
    6. Milk
    Hydromagic

    CAQ series is a unique ingredient which precipitates inside and outside hair when it is diluted with water.

    Perm Assist

    SAQ series is a unique ingredient which improves and keeps hair perming.

    Wavecanceller

    Promois WK-SAQ suppresses the hair waving induced by damage.

  • Acylated type (Promois E/E-118 series)

    A derivative bonded with a fatty acid and it is devided into washing type and conditioning type. E series, which has surfactant ability, is safe for skin and hair, and it is suitable for detergent having hair repairing effect. E-118 series, which has solubility of many solvent used for cosmetic, is suitable for cosmetic without water.

    1. Soybean
    2. Silk
    3. Keratin
    4. Collagen
    5. Fish collagen
    6. Milk
    CMC repair

    E-118 series has a similar structure to the CMC (Cell Membrane Complex) and repairs CMC.

  • Ethyl esterified type

    An ethyl esterified derivative in order to be dissolved in alcohol. It is suitable for cosmetics without water such as aerosol or nail enamel formulations.
