Coltide™ HQS is a quaternized wheat protein known for its substantivity to natural fibers, providing garment wear prevention. It enhances the softening and anti-static properties of fabric conditioners, offering consumers a noticeable difference. Its chemical name is stearyldimonium hydroxypropyl hydrolyzed wheat protein. Coltide™ HQS finds applications in fabric and laundry care as well as industrial and institutional cleaning. It acts as a fiber and surface protector.

Product Background

Natural protein conditioning agents

Add a natural touch to your fabric care product. The Coltide Naturals range of natural protein additives has been specifically designed for enhanced conditioning of natural textiles, including cotton, linen and silk.

Coltide Naturals are a range of short-chain peptides and hygroscopic amino acids which act as effective moisturizers. Our protein range includes silk, cotton, cashmere and wheat derivatives which offer opportunities for fabricspecific brand extensions. Coltide Cotton, for example, is a hydrolysed cotton derivative that attracts moisture to fibers due to its hydrophilic groups. Coltide Cotton is also naturally substantive and would improve the condition and feel of cotton and linen fabrics. As novel conditioning agents based on naturally occurring sources, Coltide Naturals offer excellent label claims and marketing potential for niche categories such as speciality fabric softeners.

Static reduction
  1. Static can build up on fibers, particularly synthetics, and produce a ‘clinging’ effect
  2. By increasing moisture content of fibers, static electricity can be conducted away
  • Proven benefit using Coltide HQS
  • Polyester/cotton fabric
  • Standard dose detergent and conditioner
  • Antistatic performance measured by charge decay meter
Summary

Hydrolysed proteins from natural sources used as skin smoothing and conditioning agents.

Applications & Uses

Markets
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

Substantivity and moisture retention

Coltide Naturals are highly substantive materials which are readily adsorbed onto and absorbed into negatively charged substrates such as cotton, cashmere, silk etc. They are substantive not only from aqueous solutions but also from conditioners and detergents. The excellent moisture retention properties of the substantive amino acids in Coltide Naturals impart a deep conditioning effect to fabrics, improving the softness and handling characteristics.

Coltide HQS is ideal for inclusion in fabric care products and is especially suited to fabric softeners. Optimum performance can be achieved with a recommended formulation inclusion level of 0.5%.

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 Imisturisers, 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 reduce the harsh defatting effects of detergent/solvent cleaning systems without impairing foaming .
 

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
  • Fabric conditioners
  • Auxiliary fabric products

Technical Details & Test Data

Perceptible Conditioning

The handle/feel of fabric is defined as the effect that the consumer can easily perceive and, as such, is very important when marketing fabric conditioners. Coltide HQS improves the lubricity of fibers and imparts texture, softness and body. This unique combination of bodying properties and lubricity is a direct result of having a fatty quaternary group covalently bonded onto a hydrolysed protein backbone.

In subjective handle tests a panel of 20 individuals showed a statistically significant preference for material treated with a conditioner containing Coltide HQS. The independent study evaluated the conditioning properties of Coltide HQS on 100% terry cotton toweling when included in an esterquat-based fabric softener. Standard machine-wash protocol was adopted and the fabrics were put through 20 wash cycles.

  • After 10 wash cycles, 65% preferred Coltide HQS
  • After 20 wash cycles, 100% preferred Coltide HQS

Croda Coltide HQS Perceptible Conditioning

Proven Fibre Protection - Wool

After 20 wash cycles, a wool sample treated with conditioner only, Image 2, shows that the cuticle has been stripped off the wool fiber, whereas the sample treated with conditioner plus Coltide HQS, Image 3, shows some cuticle damage, but the majority of the cuticle is still intact.

Proven Fibre Protection - Cotton

After 10 wash cycles, cotton fibers treated with conditioner only show some fibrillation, whereas the fiber surface of the fabric treated with conditioner plus Coltide HQS is almost as undamaged as the untreated control sample. After 20 wash cycles the conditioner with Coltide HQS sample, Image 6, shows some fibrillation, but overall the amount of fibrillation is markedly less than that found on the conditioner only sample
