1 30/04/2015 Enzymes used in the detergent industry

2 NOVOZYMES PRESENTATION30/04/ Types of enzymes are used for different detergents Cellulase Cellulose Cotton, viscose Carbohydrases Amylase Lipase Protease Starch Triglycerides Proteins Examples Rice, noodles, potatoes, corn Organic fats and oils, sebum, lipstick Substrate Blood, egg, milk grass, meat

3 NOVOZYMES PRESENTATION30/04/20153 Catalytic actions of detergent enzymes

4 NOVOZYMES PRESENTATION30/04/20154 Stain removal  Surfactants can remove most of the soils in laundry. Why do we need the enzymes?  Enzymes and surfactants generally work complementary, and together they can do the cleaning job at low temperature + mild pH  The following cartoon shows how enzymes degrade soil partially and surfactants bring the reminder into suspension

5 NOVOZYMES PRESENTATION30/04/20155 Removal of stain 1: The stain is bound to a surface Stain Substrate Fibre

6 NOVOZYMES PRESENTATION30/04/20156 Removal of stain 2: A surfactant has been added Soil Fibre Surfactant

7 NOVOZYMES PRESENTATION30/04/20157 Removal of stain 3: Enzymes are added and degrade available sites Soil Fibre Surfactant Enzyme

8 NOVOZYMES PRESENTATION30/04/20158 Removal of Stain 4: The soil comes loose and goes into suspension Soil Fibre Surfactant Enzyme

9 NOVOZYMES PRESENTATION30/04/20159 General principle of stain removal Stain Clean vest Stain less visible Stain no longer visible Wash, no enzýmes Wash with enzymes 

10 NOVOZYMES PRESENTATION30/04/ Removal of invisible stains: redeposition Conclusion: Enzymes give more permanent cleaning! Washed in dirty water, No enzymes Stain Washed Clean vest Washed in dirty water, With enzymes 

19 NOVOZYMES PRESENTATION30/04/ Facts about proteases  Novozymes proteases have been used since 1963  Are used in 75 % of all detergents  Protease is a basic ingredient in laundry and ADW detergents  Protease effects cannot be substituted by any other ingredients

20 NOVOZYMES PRESENTATION30/04/ Protease effect on blood spots not washedwashed 3 times, no protease washed 3 times, with protease

26 NOVOZYMES PRESENTATION30/04/ Low temperature profile of polarzyme Activity profile of Polarzyme shifted towards lower temperatures maintaining activity at high temperature

27 NOVOZYMES PRESENTATION30/04/ Protease benefit tested in wash & wear test  Consumer wash and wear test: 70 men asked to wear a white cotton T-shirt  T-shirts collected and cut in half  One half washed in detergent with 0.1% Polarzyme 12T  Other half washed in well known non-biological brand  T-shirts sewed up, redistributed for another wearing and washing cycle (4 cycles in total)  After each cycle the person responsible for the family´s laundry was asked to rate the result

28 NOVOZYMES PRESENTATION30/04/ Protease benefit in wash & wear test - overall consumer preference

29 NOVOZYMES PRESENTATION30/04/ Protease benefit in wash & wear test consumer preference for each performance attribute

30 NOVOZYMES PRESENTATION30/04/ Status for proteases  Protease is applied in laundry and ADW for complete removal of protein  Protease is recognised world-wide as a neccesary provider of basic detergency

31 NOVOZYMES PRESENTATION30/04/ Lipases

32 NOVOZYMES PRESENTATION30/04/ Lipase mechanism Lipase No odor Lipase Odor + + Short chain fatty acids (C 4 –C 8) Dairy soils

33 NOVOZYMES PRESENTATION30/04/ Lipases from Novozymes  Lipolase®Original lipase wild type lipase. Multi wash lipase  Lipex® First wash protein engineered Lipase. Stain removal and anti redeposition effects.

34 NOVOZYMES PRESENTATION30/04/ Effects with Lipase  First Lipase introduced in 1988  First protein engineered lipase introduced in 1998  Lipase can to some extent replace surfactants  Remove fatty matter at low temperature  Provide stain removal  Give in-depth cleaning  Reduces redeposition  General whitening + Lipase - Lipase Lipstick

35 NOVOZYMES PRESENTATION30/04/ Activity of Lipolase during drying Relative Activity (%)

36 NOVOZYMES PRESENTATION30/04/ Lipase performance  Lipolase works best at low water concentration i.e. during drying of laundry  Lipex also works at high water concentrations such as in the main wash

37 NOVOZYMES PRESENTATION30/04/ Lipase for fat removal from outside of cotton fibres no lipase with lipase Lard Sebum Olive Oil

38 NOVOZYMES PRESENTATION30/04/ Lipase effect on inside of cotton fibres Olive oil Unwashed Olive oil Washed with detergent Olive oil Washed with detergent & lipase Cross sectional specimen of yarns soiled with olive oil

39 NOVOZYMES PRESENTATION30/04/ Lipase 1’st wash effect on polyester washed without lipase washed with lipase 0.2 mm

40 NOVOZYMES PRESENTATION30/04/ Lipex - visual soil removal in 1st wash No LipexLipex 500 LU/L Lipex 1000LU/L

41 NOVOZYMES PRESENTATION30/04/ Anti-redeposition benefits after 1st wash - a secondary effect of Lipases Unwashed textiles - Lipex + Lipex

42 NOVOZYMES PRESENTATION30/04/ Status for Lipases  Lipase can be used in laundry for complete lipid removal especially at lower temperatures  Secondary effect of lipases are contribution to general cleanness by preventing redeposition of fats, oils and colorants  In depth cleaning of textile fibres  There is a smell issue that limits the dosage

43 NOVOZYMES PRESENTATION30/04/ Amylases

44 NOVOZYMES PRESENTATION30/04/ Amylases from Novozymes  Termamyl®Original amylase for high temp.  Termamyl® UltraHighly stable liquid amylase  Duramyl® Improved stability in the presence of bleach  Stainzyme®High performance “Stainfighter”. Performs well under low temperature wash conditions

45 NOVOZYMES PRESENTATION30/04/ -Amylases  Amylases hydrolyse a-1,4-glucose-linkages randomly forming soluble dextrins and oligosaccharides  The viscosity of the gelatinized starch is reduced and the solubility enhanced

46 NOVOZYMES PRESENTATION30/04/ Removal of soils containing starch  Gelatinization and swelling are needed to make the starch susceptible to enzymatic breakdown  For most starchy foods, various degrees of gelatinization result from cooking  Amylases boost the removal of starch e.g. from pasta, potato, gravy, chocolate, and baby food  Amylases prevent starch from adhering to the surface of laundry and dishes and act as a glue for particulate soils

47 NOVOZYMES PRESENTATION30/04/ Removal of invisible starch stain Washed in dirty water, No enzymes Starch stain Washed in any detergent Clean vest Washed in dirty water, With enzymes

48 NOVOZYMES PRESENTATION30/04/ pH-profile of Termamyl and Stainzyme

54 NOVOZYMES PRESENTATION30/04/ Status for Amylases  Amylases important for stain removal in laundry  Amylases are to a large extent recognised as a provider of basic detergency in laundry  Amylases very important type of enzymes for dishwashing applications  Stainzyme launch is a break through in amylase technology

55 NOVOZYMES PRESENTATION30/04/ Cellulases from Novozymes Celluzyme®first cellulase from NZ, colour clarification, prevents anti-redeposition, tolerant towards LAS. Multi-component enzyme product Carezyme®colour clarification, care cellulase, high activity on cellulose fibres, sensitive to LAS Endolase®prevents anti-redeposition and maintain whiteness (in EU liquids). Works on soluble cellulose Renozyme®colour clarification, robust towards anionic surfactants, cost effective cellulase

56 NOVOZYMES PRESENTATION30/04/ Many cellulases have a domain structure Catalytic Core Hydrophilic Linker Cellulose Binding Domain

57 NOVOZYMES PRESENTATION30/04/ “Cellulase” enzymes working together to degrade cellulose Carezyme / Renozyme CBH I CBH II EG R NR GG EG Endolase

58 NOVOZYMES PRESENTATION30/04/ Cellulase reactions  Cellulases hydrolyse b-1,4-glucose-linkages forming soluble dextrins  The substrate is water-rich amorphous cellulose In fibers this is especially found in stress points where the cellulose crystal structure is disrupted  Some cellulases are only active on soluble forms of cellulose

59 NOVOZYMES PRESENTATION30/04/ Removal of fuzz No Cellulase With Carezyme = Clearer Colors

60 NOVOZYMES PRESENTATION30/04/ Cellulase effects  Fuzz removal (Color clarification)  Depilling / anti-pilling  Soil removal (cleaning)  Anti-redeposition  Softness

62 NOVOZYMES PRESENTATION30/04/ Endolase® cleaning effects UnwashedWash 1Wash 2Wash 3 No Endolase Endolase Whiteness

63 NOVOZYMES PRESENTATION30/04/ Status for cellulases Big difference in effects of different cellulases  Color clarification & care: Celluzyme, Carezyme and Renozyme  Anti-redeposition & Cleaning: Celluzyme and Endolase Cellulases can support both basic performance and aesthetics

64 NOVOZYMES PRESENTATION30/04/ Factors influencing enzyme wash performance  Detergent composition  Enzyme concentration  Temperature  pH  Water hardness  Contact time  Type of soil  Type of wash system  Type of wash method
