Description

Rice Protein Keratin - Bio-Protective Shield for Color and Hair Strand Integrity

Rice Protein Keratin is a specialized active ingredient obtained from rice grains, rich in peptides, amino acids, and phytic acid. It is specially designed to protect the hair fiber against oxidative damage caused by solar radiation and pollution, while simultaneously preventing keratin degradation and the fading of dyed hair. It acts as a biological shield, restoring the hair's internal structure and returning its natural shine and strength.

Ingredients: Aqua, Glycerin, Hydrolyzed Rice Protein, Phytic Acid, Oryza Sativa Extract, Pentylene Glycol, Levulinic Acid, Glyceryl Caprylate.

Characteristics

Presentation: Translucent liquid, yellowish color with a weak characteristic odor.
Solubility: Fully water-soluble, dissolves in water and glycols.
Composition: Based on vegetable glycerin, mild preservation system - Levulinic Acid, Glyceryl Caprylate, Pentylene Glycol.
Origin: Vegetable, derived from rice, suitable for natural and organic cosmetics; Vegan.

Tests and Clinical Studies

The product's efficacy was demonstrated through in vivo and ex vivo studies on hair samples subjected to extreme stress:

Color Protection (Ex vivo): After 5 exposures to UV radiation and repeated washings, significant preservation of color intensity was observed compared to the control, reducing sun-induced fading.
Keratin Resistance: Protein degradation tests showed that using a 1% active concentration protects the integrity of cystine (a key amino acid of keratin) against UV damage.
Hair Fiber Recovery: Electron microscopy analysis confirmed that hair treated with this ingredient presents a much smoother cuticle and fewer micro-cracks after repeated thermal styling.
Anti-Breakage Effect: Tensile studies indicated an increase in hair strand break resistance by up to 15% compared to untreated hair.

Main Properties

Keratin Protection: Prevents the degradation of structural proteins (keratin) caused by UV radiation and thermal treatments.
Color Preservation: Maintains the intensity and shine of dyed hair, preventing shade fading under the action of the sun.
Antioxidant Effect: Neutralizes free radicals and protects the hair fiber from oxidative stress.
Structural Repair: Small peptides penetrate the hair cortex, restoring damaged bonds and improving elasticity.
Shine and Texture: Smoothes the hair cuticle, offering a silky appearance and facilitating combing.

Usage Recommendations

Cosmetic ingredient. Recommended dosage: 0.5% – 5%. Suitable for the preparation of shampoos and cleansing products for daily maintenance. Ideal as an ingredient in repairing masks, conditioners for dyed hair, or protective leave-on serums.

Applications

Revitalizing shampoos and conditioners for dyed or damaged hair.
Serums for split ends and intense shine.

Formulation Guide

Procedure: Add to the aqueous phase or the final phase of the formulation, after the emulsion has formed.
Temperature: Incorporation at temperatures ≤ 40°C is recommended to maintain biological activity.
pH Range: Stable in a pH range between 4.0 and 7.5.
Compatibility: Excellent with most surfactants (anionic, amphoteric, and non-ionic) and conditioning agents.

Frequently Asked Questions (FAQ)

Is this product an animal-derived keratin?
No. Rice Protein Keratin is a 100% vegetable alternative obtained from rice, which mimics the amino acid profile of human keratin, making it ideal for vegan products.

Can it be used on natural, undyed hair?
Yes, it is highly recommended, as it protects the natural pigments of the hair from photo-oxidation and maintains the structural strength of the strand, preventing split ends.

Is it suitable for all hair types?
Yes, it is beneficial for all hair types, but the results are most visible on chemically treated, dyed, or damaged hair.

Does it contain gluten?
Being derived from rice, it is generally considered a gluten-free ingredient, unlike wheat proteins.
