Coltide™ Silk

1 of 9 products in this brand
Coltide™ Silk is manufactured by the hydrolysis of pure silk and displays natural substantivity and excellent moisture retention properties. This imparts a moisturizing effect to the skin and a softening effect to tissues/fabrics, improving softening and handling characteristics. Applications include automatic and hand dishwashing, fabric and laundry care, and tissue coatings.

Features & Benefits

Product Background

Coltide™ Silk is manufactured by the hydrolysis of pure silk fibers under carefully controlled conditions to provide a high quality water soluble silk protein. Furthermore the natural silk raw material is obtained without harm to the silk worm or moth. Silk is renowned for its excellent moisture retention and absorption properties. Coltide™ Silk is no exception; it is composed of the free amino acids occurring in natural silk and has a molecular weight of approximately 100-150 Daltons. As a result, it too has excellent moisture retention properties.

Coltide™ Silk is a naturally substantive material. The excellent moisture retention properties of the substantive silk amino acids in Coltide™ Silk impart a moisturizing effect to skin and a softening effect to tissue, improving the softness and handling characteristics. This is particularly apparent at low ambient relative humidities when fibers feel harsh and are easily damaged as a consequence of reduced plasticity.

Applications & Uses

Markets
Fibre care

Fiber protection and repair are relatively new claims for carpet and upholstery care. Croda's Coltide Naturals range of hydrolysed and functionalised proteins have been proven to provide effective conditioning of natural fibers such as cotton, linen and silk thereby reducing fiber erosion and degradation. The Coltide Naturals range are moisture retentive, with the low molecular weight variants enabling penetration of fibers to reduce brittleness. Coltides are stable over a wide pH range and are compatible with anionic, nonionic and amphoteric surfactants. Coltide Naturals offer excellent label claims and marketing potential

Applications
  • Fabric capsules (pods)
  • Fabric detergents
  • Fabric conditioners
  • Auxiliary fabric products
Formulation guidelines

Coltide Naturals form clear solutions at all concentrations when diluted with water and are easily formulated into fabric softeners and detergents. They are compatible with all common anionic and amphoteric detergents and cationic conditioners. They are stable between pH 4 and pH 10 and will withstand heating up to a temperature of 80oC. Recommended inclusion levels are 0.1 - 0.5% active depending on the desired effect.

Applications

Coltides are ideal for inclusion in fabric care products. However, their primary application is in fabric softeners and detergents. Optimum performance can be achieved with levels as low as 1% as supplied.

  • Fabric conditioners/softeners
  • Laundry detergents - suitable for liquids, powders and tablets
  • Fine and delicate wash concentrates
  • Woolens treatments

 

Liquid soaps

In addition to household use, liquid hand soaps can be used in washrcoms when dispensers make them nue hygienic and less wasteful than soap bars. Crodasinic LS30 (sodium lauroyl sarcosinate), a mild anionic surfactant with counter irritancy properties, is recommerded to reduce the irritation of commodity anionic surfactants. Skin conditioners and moisturizers, such as Solan E or Coltide, can be used to increase the skin care properties of such systems. Solan EIE50 in particular are gentle cleansing agents which do not defat the skin and have been shown to the harsh defatting effects of detergent/solvent cleaning systems without impairing foaming.
