Color Cosmetic Trend Updates• “Nails were all the rage a few years ago, but it appears that category does not

have as tight of a grip today.” 1

• “Growth in color is shifting to eyes and lips, according to the global information company The NPD Group.”1

• NPD beauty analyst Karen Grant says that “consumers go to color when looking to change up their looks. Brands that respond to that demand quickly, swapping out their palettes in response to changing trends, are going to benefit handsomely” 1

• “Color is key when it comes to makeup with fashion and consumers are willing to experiment, as they seek way to make bold statements and refresh their look.” 1

• Eye brow makeup saw an increase by 34% 1

• Eye Shadow by 9% 1

• Lip color by 13% 1

Lip Category Market

• “Lip cosmetics are used by the vast majority of women, with approx. 87% reporting usage 2

• “Bold lip colors continue to be the on point trend, with nearly one third (32%) of lip product users aged 18-24 looking for intense lip colors” 2

• “Lip cosmetics have the highest overall reported use among color cosmetics. Lip balm, lipstick, and lip gloss all have similar rates of penetration, suggesting that many women rely on a suite of lip products depending on the occasion or desired look,” says Shannon Romanowski, beauty and personal care analyst at Mintel. 2

Most pigments have a hydrophilic surface that containspolar hydroxyl groups and adsorbed moisture.

• Agglomeration of particles causing poor skin feel

• Poor wettability and dispersibility in cosmetic fluids

• Poor dispersion stability and poor formulation stability

• Poor pressability in pressed powder

• Poor chemical stability of metal oxides

• Titanate treated pigments can be easily wetted by and dispersed in organic vehicles, like esters, mineral oils or petrolatum• Oil absorption is substantially reduced and loading of the pigments in the formula can thus be increased

Major Benefits of ITT Treatment

• Allows for high loading of pigments and fillers, so that a cream-to-powder formulation can give a powdery after feel on the skin

• Easy to make highly pigmented products such as Lipstick

• Greatly improves the compressibility in pressed powders as well as reducing breakage

• Good skin affinity because of its fatty acid functional group

Benefits of Size Reduction by Dispersions

• Easy to use. No dusty work

• High color strength for pigments

• Good batch consistency of color

• Good storage stability due to optimal formulation

• Nice skin feel

Advantages of Dispersions for Foundations

• Foundations can be made very easily by using dispersions

• No grinding is needed

• Shades are closer because of the consistency of the dispersions

• Easier to add color corrections

• Better mass to skin

• Pigments fully dispersed

• Good for global companies; each plant receives the same dispersion

Advantages of Color Dispersions in Lipsticks

• Lipsticks can be easily made• No grinds needed• Huge labor and cost savings• Less color correction is needed• Color corrections can be added more easily• Great for high concentration and high intensity lipsticks• With a high pigment concentration there is more room in formula for other ingredients• Great for volatile lipsticks because more room is available for volatile• Great for global companies

Pigmentary Dispersions

Page 19: High Impact Pigments for Color Cosmetics - Kobo … ·  High Impact Pigments for Color Cosmetics Isabella Borges – Kobo Products, Inc. in-cosmetics Brasil October 2015

www.koboproducts.com

• Wet the surface of pigment particles to promote a high

pigment content.

• Use mechanical force to de-agglomerate the pigment in

a carrier (volatile or non-volatile)

• Create dispersions with both high and low viscosities.

Steps to Optimize the Particle Size

High Impact Paradox

Consumers want high coverage, gloss and

comfort

High Amount of Pigment in the formula

Decrease glossBecome draggy

and uncomfortable

Solution: Using Pigmentary Dispersions to impart high color strength of pigments by

decreasing their particle size to create a film which is glossy and comfortable to wear

Conclusion

• Pigmentary Dispersions are convenient and effective tools to

be used in color cosmetics

• The product options available are immense, allowing these

materials to be used in any formula situation

• Eliminating the initial handling of grinding and milling of

pigment powders alleviates cost and time

• Those benefits are extended into final formulation since

dispersions are high quality, consistent and are easy to use

• Pigmentos tratados com ITT podem ser facilmente molhados edispersos em veículos orgânicos, como ésteres, óleos minerais epetrolatum. • A absorção de óleo é substancialmente reduzida e a concentrçãode pigmentos na fórmula, pode portanto, ser aumentada

Page 72: High Impact Pigments for Color Cosmetics - Kobo … ·  High Impact Pigments for Color Cosmetics Isabella Borges – Kobo Products, Inc. in-cosmetics Brasil October 2015

Principais benefícios do Tratamento ITT

• Permite alta concentração de pigmentos e fillers, para queformulas cream-to-powder possam ter um efeito de pó após aaplicação

• Produtos com alta concentração de pigmentos, como batom,podem ser produzidos facilmente

• Melhora substancialmente a compressabilidade dos póscompactos, reduzindo também a quebra

• Boa afinidade com a pele devido a presença de gruposfuncionais ácidos graxos

Vantagens das Dispersões para Batons

• Grande economia em tempo e custo• Mais fácil o ajuste e correção de cor dentro de um lote• Menor ajuste de cor na fábrica• Ótimo para batons de alta intensidade e cobertura• Com dispersões de maior concentração de pigmentos há mais

espaço na fórmula para outros ingredientes; assim como nocaso de batons com voláteis

• Molhar a superfície das partículas pigmentárias para

promover um alto teor de pigmentos.

• Usar força mecânica para desaglomerar o pigmento em

um veículo ( volátil ou não volátil)

• Possível criar dispersões de alta e baixa viscosidade

Como otimizar o tamanho de partícula
