Reetha Liquid Extract: The Natural Cleanser for Your DIY Soaps, Shampoos and Skincare

Reetha liquid extract, also called soap nut liquid extract, is a natural cleansing ingredient made from the berries of the Reetha plant. It is rich in saponins — plant compounds that foam and lift away dirt — which is why makers add it to shampoos, soaps, face washes and other DIY personal care products at around 1–2%. In short, it gives you gentle, plant-derived cleansing power without harsh synthetic detergents.

What is Reetha (soap nut) and why is it used?

Reetha grows widely in the coastal belts of Maharashtra, the Konkan region and Goa. For generations, Indian households have used the whole soap nuts to wash hair and clothes. The active ingredient is saponin, a natural surfactant that produces a soft lather in water. Azlok's Reetha liquid extract concentrates this cleansing action into an easy-to-blend liquid form.

A few useful specifics about this extract:

• INCI name: Sapindus Mukorossi / Sapindus Trifoliatus
• Source: berries of the Reetha plant
• Strength: 4:1 herb-to-extract ratio (4 kg of herb yields 1 kg of extract)
• Appearance: liquid, tasteless and practically odourless
• Free from: gluten, artificial colour, heavy metals and fertilisers
• Preservative: none added to the extract itself

Common uses in DIY and small-batch formulations

Because it is a mild, water-friendly cleanser, Reetha extract fits into a wide range of homemade and small-business products:

• Shampoos and hair rinses for gentle, sulphate-free cleansing
• Soaps, body wash and hand wash as a plant-based lathering aid
• Face wash, scrubs and cleansing serums
• Lotions and creams where a light natural cleanser is wanted
• Commercially it also appears in dishwashing liquids, laundry detergents, glass cleaners and carpet cleaners

Azlok offers it as both a water-soluble version (solvent-extracted using vegetable palm glycerin/glycerol, alcohol free) and an oil-soluble version (extracted using soy oil), so you can match it to the base of your formulation.

How to use it

The recommended usage level is 1–2% of your total formulation. That is a small amount, so measure carefully — for a 100 g batch, that works out to roughly 1–2 g.

1. Choose the water-soluble extract for water-based products (shampoos, toners, face wash) and the oil-soluble extract for oil-based products.
2. Add it during the cooling or blending stage, once your mix is no longer very hot, and stir until evenly combined.
3. Since no preservative is added to the extract, any water-containing product you make must include your own broad-spectrum preservative to prevent microbial growth.
4. Always test a small batch first and check the final feel, lather and stability before scaling up.

Safety and storage tips

Reetha is a well-known traditional herb, and no herb-drug interactions are recognised for it. Still, treat it like any active cosmetic ingredient:

• It is for external, cosmetic use — do not ingest it.
• Avoid direct contact with the eyes; saponins can sting.
• Patch-test your finished product on the inner forearm before regular use.
• Keep it out of reach of children.
• Store in a cool, dry place, tightly closed. Shelf life is up to 2 years when stored well.

Buying and pack sizes

Azlok stocks Reetha liquid extract in sizes from a handy 100 gm right up to bulk 25 KG packs (100 gm, 500 gm, 1 KG, 5 KG, 10 KG, 20 KG and 25 KG), starting at ₹299. Smaller packs suit hobbyists and testers, while the larger drums make sense for soap studios and small brands running regular batches. When you order, note whether you need the water-soluble or oil-soluble grade, and ask for the COA and MSDS documents if you are formulating for sale.

FAQ

How much Reetha liquid extract should I add to my product?

Use around 1–2% of the total weight of your formulation. For a 100 g batch that is roughly 1–2 g. Start on the lower side and adjust after testing.

Does Reetha extract contain preservatives?

No. This extract has no added preservative. If your finished product contains water, you must add your own suitable broad-spectrum preservative to keep it safe.

What is the difference between the water-soluble and oil-soluble versions?

The water-soluble version is extracted using vegetable glycerin/glycerol and is alcohol free, ideal for water-based products. The oil-soluble version uses soy oil for extraction and suits oil-based formulations.

Can I use Reetha extract directly on my skin or hair?

It is designed to be blended into formulations rather than used neat. Always dilute it as directed, keep it away from the eyes, and patch-test your finished product first.

How long does it last and how should I store it?

It has a shelf life of about two years. Keep the bottle tightly closed and store it in a cool, dry place away from direct sunlight.
