The research demonstrated that heat treatment affects wet and dry hair differently. Heat treatments produce chemical damage and limited structural harm in dry hair but cause both chemical damage and extensive structural harm in wet hair which drastically changes its physical properties. Rapid water evaporation from the hair appears to be the main cause of the observed increase in damage.
Research has explored multiple ingredients to determine their ability to function as heat insulators and prevent styling damage. The validated ingredients for heat insulation include sodium polystyrene sulfonate and quaternium-70 as well as polyquaternium-11 and PVP/DMAPA acrylate copolymer with PEG-40 sodium maleate/styrene sulfonate copolymer and silicone quaternium-22 PPG-myristyl ether. Certain humectant-like substances, such as hydrolyzed wheat protein, have been found to mitigate damage.
This research examined a heat protection spray that uses ethanol as a volatile solvent and operates without water. Excluding water from formulations and using volatile components such as ethanol to serve as the base solvent makes heat protection sprays more effective.
Preparation of heat shield spray formulations: The prototype formulations tested in this study consisted of vinylpyrrolidone/vinyl acetate co-polymer (50%) in ethanol, Quanternium-70 (50%) in propylene glycol, Bis-PEG/PPG-20/20 dimethicone, fragrance, methylchloroisothiazolinone and methylisothiazolinone (1.5%) in water, and water (for "wet" spray) or ethanol (for "dry" spray).
What is Quaternium-70 and what are its primary benefits?
Quaternium-70 is a mild cationic emulsification agent that significantly enhances the substantivity of products to skin and hair. It provides moisture-binding and anti-static properties, making it an excellent choice for hair care formulations. It also offers thermal protection against heat from curling irons and blow dryers and provides exceptional detangling properties.
In which hair care products can Quaternium-70 be used?
Quaternium-70 is versatile and can be incorporated into various hair care products, including shampoos, conditioners, mousses, cream gels, pomades, waxes, pastes, and permanent wave solutions. Its formulation compatibility makes it suitable for a wide range of applications aimed at improving hair texture and manageability.
What are the recommended use levels of Quaternium-70 in formulations?
For thermal protection benefits, it is recommended to use Quaternium-70 at a concentration of 1%. In rinse-off applications, the suggested use level goes up to 0.7%. These concentrations ensure optimal efficacy while maintaining the safety and performance of the product.
How does Quaternium-70 function as an anti-static agent?
Quaternium-70 helps to reduce electrostatic charges on hair, which can result in smoother, more manageable hair. This anti-static property is particularly beneficial for those dealing with frizzy hair issues or in climates where static electricity is more prevalent.
What makes Quaternium-70 an effective hair conditioning ingredient?
As a hair conditioning agent, Quaternium-70 leaves hair easy to comb, supple, soft, and shiny. It also imparts volume, making it an excellent choice for products formulated to enhance hair appearance and texture while providing essential conditioning benefits.
