LAURYL LACTATE.

Valuable CAS 6283-92-7 / SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT

Lauryl Lactate is a versatile skin conditioning agent and emollient that deeply moisturizes the skin, imparting a soft and smooth feel. As a lactic acid derivative, it offers mild, non-irritating exfoliating benefits to promote cell renewal and improve skin texture, while simultaneously forming a protective barrier to retain moisture.

Science

Mechanism of Action

Lauryl Lactate functions as a robust skin conditioning agent by significantly boosting skin hydration, resulting in a smooth, supple complexion. Its chemical structure, which incorporates a lactic acid component, enables gentle, non-irritating exfoliation, thereby accelerating skin cell turnover and refining overall texture. Furthermore, it establishes a protective layer on the skin's surface to enhance moisture retention and can act as a penetration enhancer, optimizing the spreadability and absorption of other active ingredients.

Key findings

  1. 01 Clinical trials involving healthy adults demonstrated that Lauryl Lactate rarely induced irritation in leave-on cream formulations at concentrations up to 10%.
  2. 02 The CIR Expert Panel deemed it safe for use in cosmetics at concentrations of 10% or less, provided the final product formulation maintains a pH of 3.5 or greater.

Stability

Lauryl Lactate exhibits optimal stability at a neutral pH (approximately 7), maintaining integrity for over 96 hours. However, it is prone to hydrolysis under strongly acidic or alkaline conditions. For typical cosmetic applications, the CIR safety assessment specifies a final formulation pH of 3.5 or greater. It is soluble in oils and alcohol, and partly dispersible in water.

Synergies

  • Enhances penetration and spreadability of other topical ingredients.

Conflicts

  • Strong acids or strong alkalis (risk of hydrolysis)
  • Combining with other strong alpha hydroxy acids (AHAs) or retinoids (potential for increased irritation or flaking, suggesting careful formulation and spaced-out usage)

Sensitization risk Low

The CIR Expert Panel confirms Lauryl Lactate's safety in cosmetic applications at concentrations of 10% or less, within formulations with a final pH of 3.5 or greater. For salon-specific products, it is considered safe at up to 30% concentration, at a pH of 3.0 or greater, for brief, discontinuous use followed by thorough rinsing, when applied by trained professionals with sun protection advisories. It holds regulatory approval from bodies like the FDA and European Commission within recommended limits, and is also FDA GRAS (Generally Recognized As Safe) as a food additive.
