Keratin Hair Protector Liquid, IO

Every flat iron pass, bleach session and rough towel dry takes a little away from the hair fiber.

Product data

Liquid hair care ingredient. The card lists hair care as the application. For this ingredient, the supplier CoA of each lot confirms the exact INCI, composition and recommended level.

Hair keratin under stress

Hair is made mostly of keratin, arranged in a cortex and protected by overlapping cuticle scales. Heat, chemical treatments and friction lift and break these scales, so hair feels rough, tangles and splits. Protective care aims to smooth the surface, reduce friction and keep the fiber feeling strong.

Product formats

Heat-protection spray

A leave-in mist applied before blow-drying or flat ironing.

appearance support mask

A weekly rinse-off mask for bleached or colored lengths.

Conditioner

Daily rinse-off care for easy combing.

Shampoo

A mild cleanser that leaves hair feeling soft.

Formulating guidance

Add the ingredient to the water phase during cool-down. Pair it with hydrolyzed keratin for a protein story, D-Panthenol for moisture and Polyquaternium-11 for a light film in sprays. More hair care ingredients are listed under actives.

Claims

Use cosmetic wording such as stronger-feeling, smoother, shinier hair and easier combing. Support numbers with combing-force or breakage tests on tresses, ideally after heat cycles.

Testing on tresses

Prepare bleached hair tresses, apply the product and run repeated flat iron passes at a fixed temperature. Compare breakage, feel and shine against untreated tresses. This gives credible data for a heat-protection claim.

Who the products are for

Customers who style with heat every day, those with bleached or colored hair and anyone growing long hair who wants fewer split ends.

Sensory design

Leave-in sprays must not leave hair sticky or heavy. Test on fine and thick hair types and adjust film-formers accordingly.

Testing

Run stability at room temperature and 40 °C, checking pH, viscosity and odor.

Packaging

Fine-mist sprays for leave-ins, tubes or jars for masks, pump bottles for shampoos and conditioners.

Batch quality

Keep the CoA for each lot and store retained samples.

Salon positioning

Professional lines often sell a protective step after coloring. A mask with this ingredient used at the salon, plus a matching spray for home use, creates a clear routine and repeat purchases.

Original recipe: heat-protection spray, 100 g

Purified water 88.70 g, Keratin Hair Protector Liquid 3.00 g as an example level per CoA, propanediol 2.00 g, Polyquaternium-11 1.50 g, panthenol 1.00 g, hydrolyzed keratin 1.00 g, PEG-40 hydrogenated castor oil 0.80 g, fragrance 0.20 g, preservative 0.80 g, citric acid solution 1.00 g. Premix fragrance and solubilizer, add to water with the remaining ingredients and stir. Adjust pH to about 5.0.

Routine for customers

A clear routine helps results: shampoo and conditioner in every wash, a mask once a week and the spray before every heat styling session. Print the steps on the packs and show them on the product page. Customers who follow a routine notice smoother, stronger-feeling hair sooner and are more likely to repurchase.

Fine versus thick hair

Offer lighter versions for fine hair and richer ones for thick or curly hair by adjusting conditioning agents, not the active.

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 the container closed in a cool place away from light.
