Abstract

Powder-to-Cream is a composition that has the appearance of a powder but the characteristics of a cream. This kind of formulation has been investigated for both skin and hair care markets since 2009. Their unique texture quickly gains consumers' interest as it makes them feel more special and luxurious even at home when spa treatments are not affordable due to recession. However, commercial products are not satisfying enough to consumers who criticize their powdery feeling and encounter stability issues. Moreover formulators are also facing some issues regarding the flexibility of the formulation (especially with PDMS) and its feasibility at higher scale. Therefore the success of these formulations has been very limited, if not inexistent. Powder-to-cream technology consists in combining an active, a powder which acts as the thickener for the active, and a powder with low affinity for the active. Powder-to-cream compositions having emulsified siloxanes and enhanced stability are described in the present work.

Powder-to-Cream is a composition that has the appearance of a powder but the characteristics of a cream. This kind of formulation has been investigated for both skin and hair care markets since 2009. Their unique texture quickly gains consumers’ interest as it makes them feel more special and luxurious even at home when spa treatments are not affordable due to recession. However, commercial products are not satisfying enough to consumers who criticize their powdery feeling and encounter stability issues. Moreover formulators are also facing some issues regarding the flexibility of the formulation (especially with PDMS) and its feasibility at higher scale. Therefore the success of these formulations has been very limited, if not inexistent.  Powder-to-cream technology consists in combining an active, a powder which acts as the thickener for the active, and a powder with low affinity for the active.

II.            Introduction

Powder-to-Cream is a composition that has the appearance of a powder but the characteristics of a cream. It is composed of a combination of a powder which acts as the thickener for a liquid active, a powder with low affinity for the active and the active itself. Although the preparation of such formulations with various types of actives (UV filters, skin moisturizers, antiperspirants, hydrotropes, anti-dandruff, bleaching agents, perfume oils or plant extracts) is claimed in the literature, only a few formulations were commercialized which applied this concept. Indeed, the success of the powder-to-cream concept was limited by factors, such as, despite the high price, commercial products are not satisfying enough to consumers who criticize their powdery feeling and stability issues. Moreover formulators are also facing issues of flexibility in formulating with PDMS) and feasibility at higher scale.

A water-containing powdery cosmetic which is liquefied by scrubbing has been described by Kose Corporation1 that claims storage stability and uniform applicability without caking or streaking. The polymeric components disclosed include polymers based on styrene, acrylate or methacrylate but no silicones. LCW described a preparation of cosmetic having the texture of a cream by subjecting it to mechanical stress2. This preparation could contain an oil, but no mention is made of specific oils or silicones. Evonik proposed a formulation containing up to 95% water and which could contain various actives such as skin moisturizers or deodorizers. As the formulations contain mainly water, the sensory feel is very fresh but not creamy. Moreover, these formulations require high shear during processing and, after drying on skin, the sensory is very dry, r...
