LUVISKOL VA 73 W is a film-forming agents and fixatives in hair care, particularly in aerosol sprays, pump sprays, liquid products, mouses and gels.
LUVISKOL VA 73 W is an easy-to-use aqueous solution that is compatible with carbomers, and is particularly suitable for alcohol-free formulations, forming a clear solution in water.
LUVISKOL VA 73 W has a K-Value (1% in ethanol) of 24.0-32.0, a solids content of 48.0-52.0%, and a water content of approx 50%.
LUVISKOL VA 73 W by BASF is a setting polymer and styling agent.
LUVISKOL VA 73 W is used in hair gels, hair creams, mousses, pump sprays and liquid hair styling preparations.
The LUVISKOL VA grades are polymeric film-forming agents that are used as hair fixatives particularly in aerosol sprays, pump sprays, liquid products, mousses and gels.
LUVISKOL VA 73 W is used a film-forming agents and fixatives in hair care, particularly in aerosol sprays, pump sprays, liquid products, mouses and gels.
LUVISKOL VA 73 W is an easy-to-use aqueous solution that is compatible with carbomers, and is particularly suitable for alcohol-free formulations, forming a clear solution in water.
LUVISKOL VA 73 W is suitability for hair-setting solutions, gels and mousses.
Because of their good solubility in water, the LUVISKOL VA 64 and LUVISKOL VA 73 grades are particularly suitable for liquid hair setting products, gels and mousses.
Further, these polymers possess excellent setting properties.
All the LUVISKOL VA grades can be completely removed from the hair by straightforward washing.
The easy-to-use aqueous LUVISKOL VA solutions (VA 64 W and VA 73 W) as well as LUVISKOL VA 64 Powder are particularly suitable for alcohol-free formulations.
In the usual concentrations (1 – 5% solid polymer), they form clear solutions in water and are very compatible with carbomers.
The moderate hydrocarbon compatibility of LUVISKOL VA 37 can be greatly improved by adding small quantities of water.
This makes LUVISKOL VA 73 W possible to achieve cloud points below 0 °C.
Uses of LUVISKOL VA 73 W:
LUVISKOL VA 73 W is used a film-forming agents and fixatives in hair care, particularly in aerosol sprays, pump sprays, liquid products, mouses and gels.
LUVISKOL VA 73 W is an easy-to-use aqueous solution that is compatible with carbomers, and is particularly suitable for alcohol-free formulations, forming a clear solution in water.
Care:
In the manufacture of hair sprays and hair setting lotions, LUVISKOL VA 73 W is worth filtering the solutions before filling, to remove any particulate matter that may be present.
The following concentrations are recommended (solids):
Aerosol hair spray 2 – 6%
Pump spray 3 – 7%
Setting lotions 1 – 5%
Setting mousse 1 – 5%
Gels 1 – 5%
Hair waxes 1 – 5%
LUVISKOL VA 73 W suitability for hair sprays:
The LUVISKOL VA grades are used as film-forming agents and fixatives in hair care.
They possess excellent properties both for aerosol sprays and for non-aerosol products.
The higher the proportion of vinylpyrrolidone, the more hygroscopic the LUVISKOL VA grade is.
The adhesion of LUVISKOL VA films (e.g. LUVISKOL VA 64 and VA 73) to the hair also increases with the proportion of vinylpyrrolidone, without adversely affecting their excellent combing-out and washing-out properties, thanks to the nonionic nature of the polymer.
LUVISKOL VA 37 and VA 55 grades are particularly suitable for hair sprays whose films LUVISKOL VA 73 W must be possible to remove from the hair by brushing.
The hair is even degreased on brushing, as the grease is effectively removed together with the LUVISKOL VA 73 W film.
The LUVISKOL VA 64 grades and the LUVISKOL VA 55 grades, by contrast, are preferable for hairsprays that are to have a particularly hydrophilic character, e.g. for use in dry climates.
LUVISKOL VA 73 W is also suitable for sprays with a high water content.
Hair sprays for dry and brittle hair should include a small quantity of plasticizer (0.1 – 0.2%), such as a polyethylene glycol like Pluracare E 400, or Palatinol M (dimethyl phthalate), Luvitol EHO, silicone oils or other plasticizers frequently used in cosmetics.
Propellant compatibility Solutions of the LUVISKOL VA grades are readily compatible with dimethyl ether (DME).
Propane, butane, isobutane, pentane DME/pentane and DME/butane mixtures can be used together with solvents such as ethanol and methylene chloride.
Characteristics of LUVISKOL VA 73 W:
Offers degreasing characteristics.
Good washing-out properties.
Improves wet and dry combability.
Solubility of LUVISKOL VA 73 W:
The solubility of LUVISKOL VA 73 W in water depends on the VP:VA ratio.
Products with a high proportion of vinylpyrrolidone (LUVISKOL VA 64 and LUVISKOL VA 73) form clear solutions in water, other grades can be dispersed in water.
The LUVISKOL VA 73 W solutions are slightly acidic.
The polymers are nonionic and thus do not need to be neutralized.
All the LUVISKOL grades are soluble in ethanol, isopropanol, n-propanol, glycerin, methylene chloride, esters and ketones.
Any precipitates that occur in solutions in ethanol or isopropanol in the cold disappear again on heating.
LUVISKOL VA 37 forms clear solutions in ethanol abs., ethanol 96% and ethanol/ water (VOC 80% and VOC 55%).
Solutions in isopropanol are clear, sometimes with a bluish tint.
Without a solubilizer, the products are not soluble in ether or aliphatic hydrocarbons.
Water absorption Water absorption by films of LUVISKOL VA compared with LUVISKOL K 30 as a function of relative humidity at 20 °C.
