ACUDYNE DHR Durable Hold Resin All Day Flexible Style and Shine for 55% VOC Sprays

Transcription

1 Personal Care ACUDYNE DHR Durable Hold Resin All Day Flexible Style and Shine for 55% VOC Sprays Description THE CHALLENGE In Hair Styling products, there is a constant trade-off between Strong Hold and All Day Flexible Style. The tradeoff is amplified in 55% VOC hair sprays. To deliver the targeted level of strong hold, compromises are often made in natural movement (flexible) and hair feel. THE SOLUTION... Introducing ACUDYNE DHR Developed specifically for high performance 55% VOC aerosol sprays and pumps, ACUDYNE DHR delivers Strong Hold and All Day Flexible Style because of its unique Dual Phase (soft and hard) polymer design. Consumer & Stylist Preference Salon testing of Acudyne DHR showed perceivable improvements over commercial benchmarks: All Day Flexible Style Shine Low Tack (Not sticky) Natural Feel (No build up)

2 BENEFIT Hair Style Durability Not Sticky on Hair Good Humidity Resistance Easy Shampoo Removability Compatibility - In all water, 55% VOC, and high VOC pump and aerosol sprays ENABLING MECHANISM 2 polymer interpenetrating phases provide a tougher film giving long-lasting hold. Hydroxylated polymer backbone composition does not form hydrated phases readily. Polymer easily swells during shampooing, and is removed from hair. Polymer structure and composition - With DME and Dymel 152a in aerosols With DME/hydrocarbon where DME is the dominant propellant - In alcohol free or alcohol containing gels Tunable Stiffness on Hair Non-corrosive to aerosol tin plate cans Low viscosity in 55% VOC formulations enables dry sprays at higher solids. No corrosion causing salts in the polymer Chemical and Physical Properties ACUDYNE DHR is a mixture of two acrylic polymers consisting of a hard phase and a soft phase. The polymers are random and linear, consisting of polymerized methacrylic acid, hydroxyethylmethacrylate, and various acrylate esters. It is manufactured as an emulsion in water. Upon neutralization, it dissolves into water or water/alcohol to form clear solutions. Physical Description Tradename: INCI Name: Appearance: ACUDYNE DHR Solids: 44-46% ph Acidity: Acrylates/Hydroxyesters Acrylates Copolymer Molecular Weight: About 60,000 Preservative: Emulsion in water (neutralizes to a clear solution) mmoles/gram active 0.75% benzoic acid

3 Hair Application Data Durability 5 Cycle Compression Durability Test on Curled Tresses Using Dia-Stron The dual phase film improves the durability of the hair style as shown in the Dia-Stron experiment, where the curled tresses were compressed 5 times. With ACUDYNE DHR, formulating a strong hold resin is possible, and the curled tresses bounce back after being compressed. With the commercial hair spray, the crust is broken after the first compression. Durability Bouncing Head Mannequin Test, 6 Hours ACUDYNE DHR improves the durability of the hair style when stressed continuously to help deliver all-day flexible style.

4 Durability Bouncing Hair Tresses for rpms Curled tresses treated with 55% VOC ACUDYNE DHR retain their definition versus commercial mega-hold 80% VOC pump spray. Least Sticky on Hair in 55% VOC Spray Dia-Stron Tack Test on Hair Tresses ACUDYNE DHR is the least sticky on hair, from the time it is sprayed until it dries. Shorter Tack Time in 55% VOC Versus 80% VOC Commercial Sprays ACUDYNE DHR in a 55% VOC pump spray gives a shorter duration of tack than 80% VOC commercial pump hair spray based on Amphomer.

5 Humidity Resistance High Humidity Curl Retention for Pump Spray at 90% RH, 25 C for 4 hrs Excellent humidity resisitance. Shine Benefit ACUDYNE DHR sprays provide a noticeable shine benefit on hair, without shine additives.
