Organoclay for Cosmetics & Personal Care

Where We Supply — Cosmetics Markets

Our cosmetic-grade organoclay is primarily exported to India and South Korea — two of the most active cosmetics manufacturing markets in Asia. The most common applications our customers work with are products that require reliable thickening: lotions, nail polish, face creams, and other personal care products where uniform viscosity and suspension stability throughout shelf life are non-negotiable. In these systems, organoclay provides both the thickening rheology (high viscosity at rest) and the thixotropic performance (smooth application under shear) that alternative thickeners struggle to deliver simultaneously.

Organoclay in Cosmetic Formulations

Applications by Cosmetic Product Type

Key Functions

Pigment Suspension

Color cosmetics require pigments (iron oxides SG 4.5–5.1, ultramarines SG 2.4, TiO₂ SG 3.9) to remain uniformly dispersed in the oil or wax phase throughout shelf life. Organoclay builds a three-dimensional platelet gel network that immobilizes these particles at rest while allowing smooth application under shear.

Silky Non-Greasy Skin Feel

The extremely fine platelet structure of ≤10 μm organoclay grades creates a distinctive silky, smooth skin feel on application — the platelets slide over each other on the skin surface, creating a lubricious sensation that contrasts with the heavy, waxy drag of conventional wax thickeners. Based on consumer panel testing across 30+ foundation formulations, organoclay-structured foundations score consistently higher on "silkiness" and "non-greasy" attributes vs. wax-only controls at equivalent viscosity.

Oil Control and Mattifying

Organoclay absorbs excess sebum on the skin surface, providing a matte finish. Particularly valued in foundations, primers, and BB creams for oily skin — organoclay at 1.0–2.0 wt% provides 3–5 hours of oil control without the chalky, heavy feel of some mineral oil-absorbing powders.

Transfer Resistance

In lip color and foundation, organoclay platelets align in the applied film and contribute to reduced smearing and transfer to surfaces (cups, garments). This mechanism supplements the wax-film transfer resistance in stick products.

W/O Emulsion Stabilization

In water-in-oil (W/O) creams and sunscreens, organoclay platelets adsorb at the oil-water droplet interface — a Pickering stabilization mechanism that provides additional mechanical barrier against droplet coalescence, supplementing chemical emulsifier stability.

Grade Selection by Oil/Silicone Phase

Note: Grades with dispersion fineness ≤10 μm (CP-MP, CP-MPS, CP-EDS) are strongly recommended for all cosmetic applications — coarser particles may cause visible specks or a gritty skin feel.

Recommended Grades for Cosmetics

Incorporation in Cosmetic Manufacturing

Lipstick and Stick Products

1. Melt wax phase (carnauba, candelilla, ozokerite) at 80–90°C
2. Add liquid oils; stir to homogenize
3. Add organoclay powder under agitation; add polar activator if using conventional grade
4. Mix with high-shear mixer or pass through colloid mill — uniform dispersion is critical for skin feel and pigment suspension
5. Cool to 75–80°C; add pre-dispersed pigments and mix
6. Add fragrance and actives at 60–70°C; cast into molds and cool

Anhydrous Sunscreen / Foundation

1. Combine liquid oils and silicones
2. Add organoclay and polar activator; mix at 2,000–3,000 rpm for 15–20 minutes
3. Add UV filters or pigments under continued high-shear mixing
4. Final homogenization to target fineness; check viscosity and sensory
