Collagen

Collagen for hair and body

This collagen is a liquid that dissolves in water. The supplier specification focuses on hair and everyday personal care: care for dry and damaged hair with added shine, a scalp that looks less flaky, hygiene products, shampoos, bath foams and shower gels. Decorative cosmetics and lipsticks are listed too. The full INCI and the recommended level for each lot are confirmed on the supplier CoA.

Proteins in rinse-off products

Proteins have a long history in shampoos and bath products. They leave hair feeling smoother and less brittle, and they make a foaming product feel gentler on the skin. For a brand, a named protein lifts a basic shampoo or shower gel into a care product with a clear benefit on the label.

Hair care

Shampoos for dry hair

Add collagen at the end of the shampoo process. Together with a mild surfactant system and a conditioning polymer, it helps dry hair feel softer after washing.

Conditioners and masks

Rinse-off conditioners give more contact time. For damaged hair, a mask with collagen, panthenol and a plant oil gives a smoother, shinier finish.

Scalp care

The supplier specification mentions a less flaky-looking scalp. A gentle scalp shampoo or tonic can carry collagen alongside soothing plant extracts.

Bath and body

Bath foams and shower gels are listed directly. Collagen adds a soft skin feel after rinsing. Add it after the surfactants are mixed, and check the viscosity again, since proteins can shift it slightly.

Lipsticks and decorative products

In lipsticks and tinted products, the liquid needs an emulsified or gel-type base, since it does not mix into pure wax. A lip cream or liquid lipstick is a practical option.

Processing

Add collagen below 40 °C, or at the end of a cold-process surfactant system. Stir gently to avoid foam. Follow the CoA for the level.

Partners

Panthenol, glycerin, polyquaternium-10 and mild betaines work well. For a fuller hair line, combine it with Silk Protein or Revitalizing hair mask with keratin. More actives are in our actives catalog.

Testing

Check color and odor in warm-cabinet tests, since proteins can darken. Use hair swatches to compare combing and shine. Make sure the preservative system is strong enough for a protein-containing product.

Claims

Use simple wording: shinier, smoother, softer hair; a caring, gentle wash; skin that feels soft after the shower.

Original recipe: collagen shine shampoo, 100 g

Distilled water 55.70 g, sodium laureth sulfate 70% 15.00 g, cocamidopropyl betaine 10.00 g, decyl glucoside 8.00 g, collagen 4.00 g, glycerin 2.00 g, panthenol 1.00 g, polyquaternium-10 0.30 g, sodium chloride 1.50 g, preservative 1.00 g, fragrance 0.50 g, citric acid solution to target pH 1.00 g. Dissolve the polymer in water, add surfactants, then the rest, and adjust pH.

Planning a hair and body line

Because collagen fits both hair and body products, a small brand can build a matching shampoo, conditioner and shower gel with one hero ingredient. Shared fragrance and packaging make the set easy to sell as a gift. Start with the shampoo for dry hair, which is the largest category, then add the shower gel and bath foam. A lip cream with the same protein can be a small add-on at checkout.

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 place away from light. Close the bottle after each use.
