Abstract
Liquid lamellar cleansing compositions are described that contain synthetic surfactants, hydrophilic emollients and exfoliant particles where 80% or more of the particles have a major axis length of between 100 and 1000 microns. The combination of the mild surfactants, moisturizers, and exfoliants provide the user with simultaneous moisturization and exfoliation in a convenient liquid cleansing product.
Claims18
A lamellar liquid cleansing composition, comprising:
- a) about 1 to 65% by wt. of one or more anionic surfactants;
- b) about 0.1 to 25% by wt. of one or more amphoteric surfactants;
- c) at least about 10% by wt. of total surfactants including one or more of anionic, amphoteric, nonionic surfactants, or a blend thereof;
- d) an effective amount of a lamellar phase inducing structurant for forming a lamellar phase in the cleansing composition, the structurant being selected from a C8 to C24 alkenyl or branched alkyl fatty acid or ester thereof with a melting point below 25 C, a C8 to C24 alkenyl or branched alkyl fatty alcohol or ether thereof with melting point below 25 C, a C5 to C12 alkyl fatty acid;
- and hydroxystearin;
- e) about 7 to about 40% by wt. of the total composition of a lipophilic emollient;
- and
- f) an effective amount of exfoliant particles having a particle size dimension along the major axis of the particle in the range of about 100 microns to about 1000 microns for exfoliating the skin during cleansing as indicated by the average preference of the Exfoliates Attribute according to the Consumer Test Protocol as measured on a 0 to 5 scale being in excess of that observed in the absence of the exfoliant particles.
A method for simultaneously exfoliating and moisturizing the skin comprising the steps of:
- a) providing a cleansing composition including
- i) about 1 to 65% by wt. of one or more anionic surfactants;
- ii) about 0.1 to 25% by wt. of one or more amphoteric surfactants;
- iii) at least about 10% by wt. of total surfactants including one or more of anionic, amphoteric, nonionic surfactants, or a blend thereof;
- iv) an effective amount of a lamellar phase inducing structurant for forming a lamellar phase in the cleansing composition, the structurant being selected from a C8 to C24 alkenyl or branched alkyl fatty acid or ester thereof with a melting point below 25 C, a C8 to C24 alkenyl or branched alkyl fatty alcohol or ether thereof with melting point below 25 C, a C5 to C12 alkyl fatty acid;
- and hydroxystearin;
- v) about 7 to 40% by wt. of the total composition of a lipophilic emollient;
- vi) an effective amount of exfoliant particles having a particle size dimension along the major axis of the particle in the range of about 100 microns to about 1000 microns for exfoliating the skin during cleansing as indicated by the average preference of the Exfoliates Attribute according to the Consumer Test Protocol as measured on a 0 to 5 scale being in excess of that observed in the absence of the exfoliant particles.
- b) applying the composition to the skin;
- c) adding sufficient water to wet the skin and develop a lather;
- d) rubbing the lather onto the skin for a time sufficient to remove dead skin cells and coat the underlying skin with the hydrophilic emollient.
