2 ACULYN Excel, high-performing suspending agent Dow s new suspension aid helps formulators provide consumers multi-functional body washes exhibiting low ph and thus mildness to the skin while exhibiting good clarity. Broad Compatibility Globally approved ACULYN Excel Efficient in suspending visual cues Clear formulations Versatility with surfactants Viscosity built 2

3 ACULYN Excel suspension aid offers clarity and efficient suspension whatever the ph ACULYN Excel NTU: 41.5 «Acrylates Copolymer» 1 NTU: «Acrylates Crosspolymer-4» NTU: 29.4 «Acrylates Copolymer» 2 NTU: 105 ACULYN Excel NTU: 13.0 Acrylates Crosspolymer -4 NTU: 18.0 ACULYN Excel NTU: 18.0 Acrylates Crosspolymer -4 NTU: 6.6 Clear Hazy Clear Blueish At ph 5.0, 12% surfactant (SLES-CAPB), 2.2% ai polymer Suspension and clarity No suspension At ph 5.0, 15% surfactant (SLES-CAPB), 2.2% ai polymer Suspension and clarity No suspension At ph 6.5, 15% surfactant (SLES-CAPB), 2.2% ai polymer 3

ACULYN Excel is compatible with main personal care ingredients present in cleansing products. ACULYN Excel is cold processible. ACULYN Excel is freeze sensitive. These are typical properties, not to be construed as specifications. 6

7 Formulation guidelines later addition of RM recommended for isethionate-containing formulations (need for heat) no impact on clarity nor suspension no impact on clarity nor suspension - water RECOMMENDED PROTOCOL - ACULYN Excel - Anionic surfactant / (Nonionic surfactant) / Amphoteric surfactant - Sodium Hydroxide qs ph>8 - citric acid qs ph specification - (cationic polymer solution) - perfume / preservative / (colorant) / (beads/glitters/...) 7

8 Performance in SLES / CAPB systems ph 5.0 ph 5.0 ph 5.0 Influence of SLES degree of ethoxylation: Conditions: 9% SLES /3% CAPB Influence of SLES/ CAPB ratio Conditions: 3/1: 9% SLES / 3% CAPB 4/1: 9.6% SLES / 2.4% CAPB 5/1: 10% SLES / 2% CAPB Influence of total surfactant content Conditions: 10%: 7.5% SLES / 2.5% CAPB 12%: 9% SLES / 3% CAPB 14%: 10.5% SLES / 3.5% CAPB 17%: 13% SLES / 4% CAPB 8

9 Performance in SLES / CAPB systems Whatever the SLES/CAPB system parameters, clarity and suspension always go in opposite directions the higher the ACULYN Excel use level, the better the clarity 9

10 ACULYN Excel, high-performing suspending agent ACULYN Excel Rheology Modifier is differentiated from industry benchmarks as it is: Able to suspend both beads and bubbles Has a broader surfactants versatility Demonstrates excellent performance to Acrylates Crosspolymer-4 at all ph including low ph values Exhibits similar performance to the industry benchmark (Acrylates Copolymer) at higher ph values thus enabling brand owners who are covering different ph values to select a more versatile suspension aid. 10
