Product Highlights
  • Used to create water-resistant, oil-based rim blocks
  • Useful for rim block cage applications
  • Can also gel mineral oil - ideal for making clear gel candles
  • Steady fragrance release
  • Crystal clear formulations
Oils & Fragrance

Air Care
All the CrystaSense rheology modifiers can be used to produce visually appealing air fresheners featuring high fragrance loading and innovative design possibilities, with steady, predictable fragrance release. The system can be used in the same way to gel insect repellents. The most suitable CrystaSense polymer depends on the polarity of the fragrance and compatibility with other formulation ingredients.

Water-Based Air Fresheners
The CrystaSense LP, MP, HP series can also be used for water-based air fresheners.

Toilet Rim Blocks
All the rheology modifiers can be used to formulate air fresheners for integration into toilet care products, such as rim blocks. Water-resistant oil-based rim blocks can be formulated using CrystaSense LP1, LP2 or LP3, and water-soluble formulations use.

Candles
CrystaSense LP1 and LP3 can both be used to gel mineral oil, therefore making them ideal for use in vibrant clear gel candles. The CrystaSense rheology modifiers will gel formulations containing mineral oil, dye and fragrance and will burn steadily throughout the candle’s lifetime. Liquid fatty acids such as Priolene™ 6907 and Prisorine™ 3501 are used to bring clarity to the formulations at low polymer concentrations. Figure 2 shows a candle made with 20% CrystaSense LP3.

Surfactants & Aqueous Systems

Hard surface cleaners
Thickened hard surface cleaners are ideal for vertical surfaces due to the increased contact time. This allows for a reduction in surfactant levels, milder pH levels and improved consumer usability. Gelled formulations appear more concentrated and dosage can be more predictable, appealing to the consumer.

Acidic Cleaners

Thickened hard surface cleaners are valuable for household applications but also I&I applications where acidic cleaners are used on heavy duty soils such as limescale and traffic film on automotive wheels. Large areas of vertical surfaces are often difficult to clean with mechanical action, therefore any cleaning solutions need to be highly effective - increased contact time for acid cleaners will equate to cleaner surfaces.

Applications
  • Air care
  • Toilet care
  • Hard surface cleaners
  • I&I cleaners

The highly versatile polymers can be used with oils and fragrance to formulate visually appealing air fresheners with high fragrance loadings, vibrant gel candles and water-soluble or water-resistant toilet care products. The CrystaSense LP, MP, HP Series also shows compatibility with aqueous systems and can add structure to shear thinning hard surface cleaners, including acidic formulations, allowing increased contact time and more controlled application.

Technical Details & Test Data

Clearly Superior Gellants
  • The CrystaSense LP, MP, HP Series consists of six unique patented amide polymers designed for use as rheology modifiers in a wide range of formulation types and formats.
  • The gellants are chemically inert and work by forming a three dimensional structure, locked in by hydrogen bonding. Oil is attracted to the fatty dimer acid chains and the hydrophobic pockets that are formed trap the oil. The strength, or hardness, of the gel is controlled by the polymer concentration and molecular weight of the gellant.
Polymer Selection

As each CrystaSense gellant has different chemistry, the series has a wide range of compatibilities with other ingredients. A suitable gel can be chosen depending on the other ingredients in the formulations, what the intended application of the product is, and the ideal physical characteristics. Figure 5 shows a variety of common ingredients and the CrystaSense amide polymer that is likely to show compatibility with that ingredient, based on polarity.

Croda CrystaSense LP1 Polymer Selection

The properties of gels made with CrystaSense rheology modifiers vary depending on a number of factors. Table 2 shows how the physical properties of the gels change by increasing or decreasing concentration and the molecular weight of the rheology modifier.
 

System Compatibility Decreased molecular weight = Increased compatibility
Gel Strength Increased concentration = Increased gel strength
Increased molecular weight = Increased gel strength
Gel Clarity Increased concentration = Increased gel clarity
Decreased molecular weight = Increased gel clarity

Compatibility
  • Oils & fragrance
  • Surfactants & aqueous systems
  • Acidic formulations
Formulating

CrystaSense LP are solid colourless wax-like pastilles and therefore require heating for processing. For example, to produce an air freshener all ingredients except volatile components must be mixed and heated to at least the softening point of the CrystaSense component. The mixture is then cooled to a suitable temperature and the volatile ingredients are added. The mixture is then poured into moulds; full gel strength is obtained after approximately two hours at room temperature.
