General Information:

Uses in the Cosmetic Industry

· Facial Cleansers

Quaternium 73 is effective at very low concentration of 0.005-0.02% therefore, it is suitable for oily, acne-prone and combination skin facial cleansers.

It is primarily used as a powerful antibacterial agent for acne-prone skin by reducing and preventing breakouts through targeting acne-causing bacteria.

· Toners

In toners, quaternium 73 works well in oily and acne-prone skin thus it is used mainly for antibacterial and anti-acne control.

It acts as a preservative booster with a light, non-sticky feel since it is gentle, non-exfoliating and suitable for daily use.

· Lotions

Quaternium 73 is mainly used in lotion for antibacterial and anti-acne control hence it helps prevent and reduce breakouts, mainly in body or facial lotions for acne-prone skin.

However, it is suitable for leave-on formulations when properly balanced at very low concentrations of 0.005-0.01%.

Remember, quaternium 73 does not affect lotion texture because it is non-comedogenic. Therefore, it acts as a preservative booster, supporting product microbial stability.

· Essences

Here it helps to control acne-causing bacteria in lightweight, leave on products since it is a non-comedogenic and does not leave residue.

It acts as a preservative booster thus is suitable for watery, fast-absorbing essences.

Since it’s suitable for oily and acne-prone skin, quaternium 73 is mainly used for antibacterial and anti-acne protection.

· Shampoos

Quaternium 73 does not condition hair nor improve slip or replace anti-fungal dandruff. It is used for antibacterial scalp care.

In shampoos, it is very effective at low levels thus it works well on oily and problem scalps. Moreover, it acts as a preservative booster so it helps control scalp bacteria, color, and scalp acne.

· Conditioners

Quaternium 73 supports microbial stability as a preservative booster thus helps control bacteria on the scalp, reducing scalp acne and color.

In conditioners, it is effective at a very low concentration so it does not provide hair conditioning, detangling or shines; rather it is used for antibacterial and scalp-care purposes.

· Shower Gels

In shower gel, quaternium 73 is used for antibacterial and anti-acne skin protection therefore, it keeps the skin clean and refreshed by controlling skin bacteria.

This cosmetic ingredient remains effective even on oily skin areas since it reduces microbial overgrowth without over-drying.

Quaternium 73 acts as a preservative booster by reducing the need for high levels of traditional preservatives thus improving microbial safety of the shower gel.

Formulating Quaternium for Cosmetic Products

· Working pH

Quaternium 73 is most effective in acidic formulation of pH 3.5-6.0 because it is a cationic conditioning polymer hence it binds effectively to negatively charged surfaces like hair or skin.

Remember, it may lose its effectiveness or may precipitate if the pH is more than 7 since high pH reduces its cationic activity.

· Recommended Concentration

The recommended concentration depends on the type of the product, so overuse may leave a slightly sticky or heavy feel on hair or skin. It can interact with anionic surfactants since it’s a cationic polymer thus the pH and the surfactant system affect effective concentration.

· Solubility

Quaternium 73 is soluble in water so it is best to pre-dissolve in water before adding to the formulation. More importantly, it is slightly soluble in glycerin and practically insoluble in oils or non-polar solvents therefore it should be incorporated in aqueous phases of formulations.

· Thermal Stability

It is stable up to 80c in aqueous solutions thus should be added later in the formulation process to avoid degradation.

This helps maintain cationic activity and solubility.

Chemical Composition of Cosmetic Grade Quaternium 73

Quaternium is designed for safe conditioning and film-forming on skin and hair since its water-soluble quaternary ammonium polymer. It is made of an acrylic-based polymer backbone with permanent positive charges and anti-static performance in cosmetic products.

Working Mechanism

Quaternium 73 works by binding to negatively charged skin and hair since it’s a positively charged conditioning polymer.

Its performances is based on electrostatic attraction and film formation since it deposits evenly on hair shafts or skin, even in rinse of products.

Because of its ionic bonding, part of the polymer remains after rinsing hence improving softness, moisture retention and manageability without clogging pores.

Quaternium 73 works on the surface hence does not treat acne or kill bacterial since it’s not an active treatment or preservative.

Benefits in Skincare and Hair Products

· Antimicrobial Properties

This ingredient has a mild, supportive antimicrobial activity due to its positive charge thus can reduce microbial attachment on skin or hair surface.

· Inhibit Melanin Formation

It does not inhibit melanin formation but it indirectly improves skin appearance by hydration and barrier support.

· Anti-inflammatory Effects

Quaternium 73 hydrates and soothes skin to minimize redness and friction therefore it indirectly reduces skin irritation and inflammation.

· Antiacne

It supports acne-prone skin but does not treat acne directly thus it maintain skin barrier, which can prevent irritation-induced breakouts.

· Skin Brightening

Quaternium indirectly improves hydration and skin barrier, making skin look smoother and radiant.

· Anti-static Properties

It neutralizes static electricity on hair therefore it is useful in shampoos, conditioners and hair serum for dry or fizzy hair.

Safety and Approval for Use

Quaternium 73 is a safe, compliant conditioning ingredient that is generally well tolerated by skin and scalp.

This cosmetic ingredient is approved for cosmetic use in major markets like EU, USA and internationally hence it is not banned under EU cosmetic regulation [EC] No.1223/2009.

When it is properly formulated, it must be listed on labels under its INCI name [Quaternium-73/Polyquaternium-73].
