Papain

Papain at a glance

Papain is a powder that dissolves in water. It is a protein-splitting enzyme from papaya. In cosmetics papain is used for gentle enzyme exfoliation: it helps loosen the dull cells on the skin surface, so skin looks smoother and brighter without scrubbing. Confirm activity, purity and microbial quality on the supplier CoA.

Enzyme exfoliation

Unlike acids or scrubs, enzymes work by breaking down the proteins that hold dull cells together. The result is a gentle refining effect that suits users who find scrubs too rough. Enzyme peels and powder cleansers are popular for this reason.

Product formats

Enzyme powder cleansers

Dry powders that foam lightly when mixed with water in the palm.

Enzyme peel masks

Gel masks left on for a few minutes and rinsed off.

Smoothing creams

Low levels in rinse-off creams.

Foot care

Enzyme masks for rough feet.

Processing

Enzymes lose activity with heat, extreme pH and some preservatives. Add papain at cool-down, below about 40 °C, and keep the pH near neutral. For best stability, put papain in a dry product such as a powder cleanser, where water activates it right before use.

Good partners

Bromelain adds a pineapple enzyme. Rice starch and Oat milk suit powder cleansers, and Allantoin gives a soothing feel. Browse more in the actives catalog.

Testing

Measure enzyme activity over time if possible, since activity drops in water-based products. Run patch tests, because enzymes can tingle.

Claims

Gentle exfoliation; skin looks smoother and brighter; scrub-free refining.

Characteristics

Form: powder. Solubility: water. Type: protein-splitting enzyme from papaya. Activity and grade: supplier CoA.

Original recipe: enzyme powder cleanser, 100 g

Rice starch 50.00 g, sodium cocoyl isethionate 25.00 g, kaolin 15.00 g, papain 3.00 g, oat milk powder 5.00 g, allantoin 1.00 g, maltodextrin 1.00 g. Mix all powders thoroughly in a dry, clean bowl, sieve and fill into airtight containers. Users mix a small amount with water in the palm before use.

Directions for users

Suggest using enzyme products one to three times a week, avoiding the eye area and rinsing well. Advise a patch test before the first use and following with a moisturizer.

Moisture protection

Dry enzyme products should stay dry until use. Choose airtight jars or sachets and advise users to keep wet fingers out of the container.

Range ideas

An enzyme powder cleanser, a peel mask and a foot mask can share papain.

Lot records

Keep each CoA with the batch file and note the lot used.

Choosing the right format

A dry powder cleanser keeps the enzyme stable for the longest time, because there is no water until use. A gel peel mask is more convenient but needs careful testing, since enzyme activity can fall during storage. Some brands use two-part kits, with a powder and a liquid activator mixed just before application. Choose the format according to the shelf life you need.

Contact time

In masks, the contact time shapes the experience. Five to ten minutes is common for enzyme masks. Test several contact times with volunteers and give clear directions on the label.

Avoiding irritation

Keep enzyme levels moderate and avoid combining papain with strong acids or retinoids in the same product.

Label wording

Describe the product as a gentle enzyme exfoliant and explain the routine simply. Avoid promising dramatic results; a smoother, brighter look after regular use is an honest message that matches the experience.

Record the lot number in your batch log so every production run can be traced back to its certificate of analysis. Retain a small sample of each lot for at least the shelf life of the finished product, since it makes later quality questions much easier to answer.

Storage

Store closed in a cool, dry place. Close the container after use.
