Mechanism of action of cationic conditioning agent in scalp-hair interface system
Scalp care skin care
I.Scalp care≠hair care
Traditional hair care products have a single core focus, focusing on only two points: the care of the surface of the hair, the smooth touch immediately after washing, and only the surface repair, ignoring the health of the scalp.
But now the current trend of scalp care and skin care has changed this idea, no longer just staring at the hair itself, but focusing on a complete system: the scalp-hair follicle-hair interface system.
This also allows the product positioning of cationic conditioners to be upgraded, getting rid of a single functional label：
❌ No longer just a simple hair softener
instead
✔ Scalp hair interface regulator
✔ Charge neutralization and stabilization system
✔ Hair fiber arrangement regulator
The daily formula is used in combination with Stearalkonium chloride, which can further optimize the interface adaptability and make the overall conditioning effect more balanced and gentle.
II.Core principle
The surface of our hair is naturally negatively charged, especially damaged hair, this characteristic will be more obvious.
After the hair scales are opened and damaged, the negative charge on the surface increases, causing the hair friction to become larger, dry and frizzy. Daily combing and blowing can easily produce static electricity and blow hair into knots.The core action logic of our commonly used quaternary ammonium salt cationic conditioners is simple and intuitive: relying on electrostatic adsorption, they are firmly attached to the surface of the hair.
In the end, three major effects are achieved: a uniform cationic protective film is formed on the surface of the hair, the coefficient of friction of the hair is greatly reduced, the messy hair fibers are straightened out, and the static electricity problem of frizz is improved from the root cause.
3.1 Molecular properties
Cetrimonium Chloride is a short-chain quaternary ammonium salt, which is particularly water-soluble, adsorbs on the hair and scalp very quickly, and is effective and efficient.
3.2 Core functional features
Focusing on rapid conditioning effect, it is the best choice for lightweight hair care formula：
-Quickly neutralize excess charge in the hair and eliminate static electricity
-Improve the knotting problem immediately after washing, and greatly improve the smoothness of combing hair
-The skin feels fresh and light, without a heavy and sticky feeling
3.3 Applicable scenarios
Based on the above characteristics, this system is more suitable for lightweight hair care products：
-Refreshing light conditioner
-Washed scalp care products
-Special formula for fine and soft hair and oily scalp
3.4 Adaptability of scalp skin care
In line with the core needs of scalp skin care, it focuses on refreshing, soothing, cleansing and conditioning the scalp.
The biggest advantage is that there is almost no residue, no film will accumulate on the scalp, and the problem of clogging of hair follicles can be avoided to the greatest extent. It is very friendly to people with oily and sensitive scalp.Sebacic acid copolymer can further enhance the film-forming breathability of the formula, taking into account the conditioning effect and scalp breathing.
4.1 Comprehensive upgrade of molecular structure
Behentrimonium Chloride is equipped with a long hydrophobic chain of C22, with a larger molecular weight, a stronger hydrophobic anchoring effect, and a binding force to the stratum corneum of the hair far exceeds that of the short-chain system.
4.2 Advantages of film-forming mechanism
Compared with MY1631, it can form a thicker and longer-lasting conditioning protective film on the surface of the hair.
The overall adsorption force is stronger, the adhesion rate of active ingredients is higher, the flushing speed is slower, the hair care effect is longer-lasting, and the long-lasting softening ability is outstanding.Adding TRIBEHENIN to the formula can help optimize the film-forming texture, make the film body more uniform and delicate, and improve the overall moisture content.
4.3 Getting started with somatosensory
It is a typical high-end moisturizing experience: the cream is mellow and silky, and has a strong ability to comb and knot hair. After blow-drying, the hair is smooth and drape very well, and the effect of smoothing frizz is full.
4.4 Core structure advantages
The long hydrophobic chain has its own crystallization properties, which can form a regular and orderly protective film on the surface of the stratum corneum of the hair. It is not a false slip floating on the surface, but a true and supple texture for deep repair.
V.Synergy between cationic conditioning agent and formula system
5.1 Anionic surfactants (shampoo system)
The interaction of cation and anionic components will form a condensed layer structure, which accurately regulates the adhesion of active ingredients to avoid excessive residues or insufficient effects.
5.2 Fatty alcohol/Structural regulator
Stabilizing the structure of the overall conditioning system can greatly enhance the mellow texture of the paste of the MY2231 system and make the product texture more delicate and uniform.
5.3 Silicone oil/Ester grease
Further enhance the smooth touch of the hair, reduce frictional resistance, and at the same time make the conditioning ingredients adhere more evenly to the surface of the hair, and the repair effect is more comprehensive.
VI.Formula design ideas
6.1 Lightweight scalp Conditioning Products
With MY1631 as the core raw material, the main low-residue, no-accumulation formula, with a quick rinse design, is suitable for daily refreshing care needs, nourishing the scalp and not stuffy acne.
6.2 High-end nourishing hair care cream
With MY2231 as the core, it builds a layered and delicate structure, has a high adhesion rate of ingredients, and has strong moisturizing and repairing power. It is specially aimed at dry, perm and damaged hair.
VII.Core product adaptation positioning
OSMFACT® MY1631
Fast-acting lightweight conditioning raw materials, different solvent systems, low residue, scalp-friendly, suitable for refreshing, daily basic care formula.
OSMFACT® MY2231
High-performance waxy conditioning system and different solvent systems can create a mellow and silky product texture and enhance the high-grade smooth texture of hair. It is the core raw material of high-end nourishing hair care products.
VIII.Summary of core technologies
Nowadays, cationic conditioners are no longer simple hair care, but engineering-grade repair raw materials for the scalp-hair interface.
Its final use effect mainly depends on four core factors: component adsorption speed, hydrophobic chain molecular structure, hair stratum corneum adhesion performance, and compatibility with anions, silicone oils, fatty alcohol and other systems. Adaptability.
