5g 4-Butyl Resorcinol Powder (Activated Resorcinol)

4-Butyl Resorcinol Powder, often referred to in the cosmetic industry as Activated Resorcinol, is regarded as one of the most effective non-hydroquinone skin-brightening ingredients available for professional cosmetic formulations. Unlike traditional brightening agents that mainly target surface discoloration, 4-Butyl Resorcinol works at the biological level by significantly reducing the activity of the enzymes responsible for melanin production before excess pigment forms.

What makes this ingredient exceptional is its ability to inhibit both Tyrosinase and Tyrosinase-Related Protein-1 (TRP-1), two key enzymes involved in melanogenesis. Many brightening ingredients primarily target tyrosinase alone, whereas 4-Butyl Resorcinol interferes with multiple stages of the pigmentation pathway, making it particularly effective against stubborn hyperpigmentation.

It is widely incorporated into advanced formulations developed to address:

• Post-inflammatory hyperpigmentation (PIH)
• Melasma
• Sun-induced pigmentation
• Age spots
• Acne marks
• Uneven skin tone
• Dark knuckles, elbows and knees
• Underarm discoloration
• Intimate area brightening products

One of its greatest advantages is that it delivers visible brightening results at remarkably low concentrations, allowing formulators to create highly effective products without relying on aggressive exfoliation or high percentages of acids. When properly formulated, it gradually restores a clearer, brighter and more even complexion while helping minimize the risk of irritation commonly associated with stronger depigmenting agents.

Because of its potency, 4-Butyl Resorcinol is frequently considered a premium active ingredient and is commonly found in dermatologist-recommended pigmentation serums, luxury brightening creams, intensive spot correctors and professional skin correction treatments worldwide.

INCI Name: Butylresorcinol

CAS Number: 18979-61-8

Appearance: Fine white to slightly off-white crystalline powder with very low odor.

Country of Origin: China

Formation: Synthetic cosmetic active produced through controlled organic synthesis to achieve high purity and consistent cosmetic performance.

Specification:

• Assay: ≥99%
• Cosmetic grade
• High purity
• Low heavy metal content
• Excellent formulation stability under recommended conditions
• Suitable for leave-on cosmetic applications

Grade: Cosmetic Grade

pH Stability:

Performs best in formulations with a pH between 4.5 and 6.5, where it maintains excellent activity and stability. Although it can tolerate a slightly wider range, prolonged exposure to highly acidic or highly alkaline formulations may gradually reduce its effectiveness. It is therefore most suitable for mildly acidic skincare systems, which also align well with the skin's natural pH.

Recommended Usage Percentage:

• Daily brightening serums: 0.1–0.3%
• Brightening creams and lotions: 0.2–0.5%
• Intensive pigmentation treatments: 0.3–1%
• Professional depigmenting formulations: Up to 1%

Most formulators achieve excellent results between 0.3% and 0.5%, where efficacy is high while maintaining excellent skin comfort.

Solubility:

4-Butyl Resorcinol is poorly soluble in water.

It dissolves readily in various cosmetic solvents including:

• Propanediol
• Ethoxydiglycol
• Propylene Glycol
• Butylene Glycol (limited)
• Pentylene Glycol
• Certain cosmetic esters
• Ethanol

Because of its low water solubility, it should first be dissolved in a suitable solvent before incorporation into emulsions or water-based systems to ensure uniform distribution and optimal performance.

Compatibility:

One of the strengths of 4-Butyl Resorcinol is how well it integrates into comprehensive pigmentation-correction systems. It works synergistically with many modern brightening and skin-renewing ingredients, making it a favorite in advanced formulations.

Compatible with:

• Niacinamide
• Tranexamic Acid (TXA)
• Alpha Arbutin
• N-Acetyl Glucosamine (NAG)
• Kojic Acid Dipalmitate
• Vitamin C derivatives (MAP, SAP, AA2G, Ethyl Ascorbic Acid)
• Azelaic Acid
• Licorice Root Extract
• Glutathione
• Ferulic Acid
• Ceramides
• Panthenol
• Hyaluronic Acid
• Allantoin
• Peptides
• Centella Asiatica Extract
• Green Tea Extract

It also performs exceptionally well alongside carefully balanced exfoliating systems such as Mandelic Acid, Lactic Acid and Polyhydroxy Acids (PHAs), where improved skin renewal can complement its pigment-correcting action without unnecessarily increasing irritation.

Mixing Phase & Temperature Range:

Typically incorporated during the cool-down phase after first dissolving in a compatible solvent.

Recommended incorporation temperature:

Below 40°C, preferably 25–35°C.

Avoid prolonged exposure to elevated temperatures, as excessive heat may reduce stability over time.

Application:

Ideal for formulating:

• Facial brightening serums
• Dark spot correctors
• Hyperpigmentation treatments
• Melasma creams
• Brightening facial moisturizers
• Neck correction creams
• Underarm brightening creams
• Intimate brightening products
• Brightening body lotions
• Dark knuckle treatments
• Dark elbow and knee creams
• Acne mark correction serums
• Professional pigmentation treatments

Performance:

4-Butyl Resorcinol is recognized for delivering targeted pigment correction rather than general skin bleaching. Its mechanism focuses on reducing the formation of excess melanin, helping discoloration fade gradually as the skin naturally renews itself.

With consistent use in a well-formulated product, it can help:

• Visibly reduce stubborn hyperpigmentation.
• Improve the appearance of melasma and sun-induced discoloration.
• Fade post-acne marks and post-inflammatory hyperpigmentation.
• Brighten dull, uneven-looking skin.
• Promote a more uniform skin tone without creating an unnatural whitening effect.
• Help minimize the recurrence of new dark spots by reducing excessive melanin production.
• Deliver noticeable results at relatively low concentrations, making it highly efficient in premium formulations.

Because pigmentation develops over time, visible improvement typically occurs progressively with regular use alongside diligent daily sunscreen application.

Storage:

Store tightly sealed in its original container in a cool, dry environment away from moisture, excessive heat and direct sunlight. Protect from prolonged exposure to air and humidity to preserve product quality and potency.

Shelf Life:

Approximately 24 months from the manufacturing date when stored under recommended conditions in unopened packaging.

Precaution:

• For external cosmetic use only.
• Use within the recommended concentration range.
• Always dissolve completely in an appropriate solvent before adding to the formulation.
• Avoid unnecessary exposure to high processing temperatures.
• Conduct stability and compatibility testing when developing new formulations.
• Perform a patch test before widespread use, particularly on sensitive skin.
• Daily use of a broad-spectrum sunscreen is strongly recommended in pigmentation-correction routines to help maintain results and reduce the formation of new discoloration.
• Keep out of reach of children.
