Neutral enzyme TS-13 is recommended for the following advantage in the finishing in the laundry.

• High color contrast finish

• Good strength retention

• High degree of reproducibility and reliability

• Improved wash look, or create new looks

• Easy and cost effective reformulation

Typical Characteristics

Appearance: Light Yellow Powder

Odor: Slight fermentation odor

Activity: 6000 ECU/g

The optimal pH and Temperature ranges for Neutral enzyme TS-13 are pH 5.5-6.5

and 40-60°C to optimize its performance. Usually the Neutral enzyme TS-13 is mixed with buffer salts and some dispersing agents to do the reformulations.

The user should take the actual processing pH into considerations and make sure the pH of the bath is in the right range of pH 5.0-6.5 under the addition of 2% of the reformulated products, and if not, add some acid to adjust the pH to 5.0-6.5 to get the optimal activity and performance.

Neutral enzyme TS-13 unitable for reformulations in the laundry. The following reformulation recipe is a basic recipe for your reference and you could adjust the base enzyme and the buffer system according to the finishing effect and local environment requirements

A typical reformulation is based on the following general formula, targeting an end-use dosage between 0.5-2% o.w.g.:

3-7% Cellulase enzyme TS-13

20% monoammonium phosphate

5% citric acid

10-20% Surfactants like some anti-back staining agents

20-40% Soluble fillers, e.g. sodium sulphate

0-10% Conditioner, e.g. starch and silicates,talcum powder

A phosphate or phosphate/citrate buffer is particularly suitable for the pH range in requirement in 5.5-6.5. However, a combination of citric acid and adipic acid (6% and 50% respectively) can be used as a non-phosphate alternative.

The suggested buffer systems should be used as a starting point; additional adjustment to meet local conditions may be necessary (see recipes).

Neutral enzyme TS-13 is compatible with most nonionic surfactants. Anionic surfactants should be avoided. In particular, alcohol ethoxylates are widely used in denim finishing. Most surfactants of interest are liquids or pastes at room temperature. However, it is possible to include a liquid surfactant in a solid formulation by spraying the surfactant onto a carrier material such as kaolin, silicate or starch.

The formulation should be thoroughly mixed to ensure homogeneity. Auxiliary compatibility with Neutral enzyme TS-13 should be determined by conducting performance and enzyme stability evaluations.
