As hot weather arrives, high-SPF sunscreen lotions and outdoor sun sprays enter their peak sales season of the year. To achieve high sun protection factors of SPF50+ and PA++++, mainstream formulas incorporate high levels of oils, organic UV filters and physical powders. However, this creates a widespread industry pain point: products are prone to oil-water separation, greasy surface, powder sedimentation and viscosity collapse during high-temperature storage in summer, long-distance ocean transportation and outdoor exposure to intense sunlight.

Newman TR Series with INCI name Acrylates/C10-30 Alkyl Acrylate Crosspolymer, including TR-1, TR-2 and TR-3, integrates four core functions: emulsification, thickening, suspension and high-temperature stabilization. Compatible without conventional emulsifiers, the series locks high-oil formula systems at the molecular level and fundamentally eliminates oil-water separation of sun care products under hot conditions.

1. NM-Carbomer R-1: Long-Term Stabilizing Base for High-Oil Sunscreens

Conventional thickening and emulsifying systems are susceptible to thermal demulsification under high summer temperatures, resulting in water bleeding, phase separation and viscosity thinning. As a universal stabilizing substrate for sun care, NM-Carbomer TR-1 enables the formulation of oil-in-water emulsions without additional traditional emulsifiers. It boasts a broad pH compatibility range: it can emulsify up to 20 wt.% oil at pH 3.0–11.0, and up to 30 wt.% oil at pH 4.0–5.5, perfectly accommodating skincare and UV-filter oils in summer sunscreen formulas. Supporting both cold and hot processing for flexible production, TR-1 delivers long-term emulsion stability at a low dosage of 0.2–1.5 wt.%. Combined with other carbomer polymers, it further enhances thickening performance, allowing formulators to customize sunscreen lotions with variable viscosities for wide application coverage.

2. NM-Carbomer TR-2: High Oil Loading & Light Texture, Ideal for Sunscreen Sprays

Custom-designed for sunscreen spray emulsions, NM-Carbomer TR-2 achieves an oil emulsification capacity up to 50 wt.%, far exceeding conventional emulsifying ingredients. Only a minimal dosage of 0.2–0.5 wt.% is required to prepare low-viscosity O/W emulsions. The resulting sunscreen sprays feature ultra-light texture and excellent fluidity, spread effortlessly on skin, offer superior atomization performance, and rapidly form absorbable films upon application on face and body.

3. NM-Carbomer TR-3: Preservative-Free Mild Stabilizer for Sensitive Skin Sunscreens

As a preservative-free polymeric emulsifier, Newman NM-Carbomer TR-3 completely eliminates preservative-induced sensitization risks at the ingredient level. Tailored for barrier-compromised and vulnerable sensitive skin in hot summer conditions, it serves as a core raw material for summer-sensitive-skin sunscreen and skincare repair products.

Featuring low dosage for stable systems and high oil loading without greasiness, it can carry up to 50 wt.% oils and is compatible with a wide range of UV filters and skincare oils. It simplifies formula with HLB calculation required. Finished products deliver an ultra-light, refreshing texture with minimal residue, enabling all-day gentle protection for sensitive skin while maintaining high sun protection efficacy and excellent high-temperature stability.

The core competitiveness of summer sunscreen products no longer lies merely in SPF/PA ratings, but in high-temperature stability, shelf-life consistency and superior skin feel. Newman NM-Carbomer TR series consists of three differentiated acrylate copolymers that effectively solve the high-temperature demulsification challenge of high-protection sunscreens. With the core advantages of high oil loading, high temperature resistance, zero delamination, refreshing texture and mildness, it adapts to full sunscreen scenarios including sunscreen creams, lotions and sprays for sensitive skin. It helps brands stabilize product quality, reduce after-sales risks and develop differentiated best-selling summer sunscreen products.
